The infant consuming from the bottle has a developing immune system, a higher fluid intake relative to body weight than an adult, and no ability to signal when something is wrong. This makes <strong>baby bottle manufacturing<\/strong> the application in which material safety, dimensional precision, contamination-free production, and structural performance under drop impact must all be met simultaneously \u2014 and where the consequences of failure are, uniquely, both regulatory and ethical.<\/p>\n<p>The global pivot away from polycarbonate (PC) as the standard baby bottle resin \u2014 driven by BPA migration concerns that became public knowledge in the mid-2000s \u2014 created a commercial opportunity for alternative resins, particularly Eastman&#8217;s Tritan\u2122 copolyester. Today, <strong>Tritan baby bottle manufacturing<\/strong> by injection stretch blow moulding has become the industry standard for premium baby bottles in Korea, Japan, and Western markets, and PETG is the standard for mid-tier baby bottles where Tritan&#8217;s cost is a constraint. A correctly specified <strong>baby bottle manufacturing machine<\/strong> \u2014 whether a <strong>BPA-free bottle machine<\/strong> for Tritan, or a <strong>baby bottle blow moulding<\/strong> line for PETG in higher-volume configurations \u2014 must address resin-specific processing requirements, wide-neck mould geometry, GMP documentation, and drop-resistance engineering simultaneously. This guide covers how to configure an <strong>ISBM machine for baby bottles<\/strong> correctly across all four dimensions, including the specific requirements for <strong>Tritan injection stretch blow moulding<\/strong> that most general ISBM guides overlook.<\/p>\n<p><!-- JUMP NAV --><\/p>\n<nav style=\"background: #f0f6ff; border: 1px solid #c4d9f0; border-left: 5px solid #0066cc; border-radius: 0 8px 8px 0; padding: 20px 24px; margin: 0 0 44px;\" aria-label=\"\u0932\u0947\u0916 \u0915\u0940 \u0935\u093f\u0937\u092f-\u0938\u0942\u091a\u0940\">\n<p style=\"font-size: 12px; font-weight: 800; color: #003366; text-transform: uppercase; letter-spacing: 0.10em; margin: 0 0 12px;\">\u0905\u0902\u0924\u0930\u094d\u0935\u0938\u094d\u0924\u0941<\/p>\n<ol style=\"margin: 0; padding-left: 20px; font-family: Arial,sans-serif; font-size: 14px; line-height: 2.1; color: #0066cc;\">\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#why-strict\">Why Baby Bottles Have the Strictest Packaging Requirements<\/a><\/li>\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#resins\">The Three Safe Resins for Baby Bottle ISBM<\/a><\/li>\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#processing\">Processing Requirements \u2014 What Changes for Each Resin<\/a><\/li>\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#why-isbm\">Why ISBM Is the Right Process for Baby Bottles<\/a><\/li>\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#machine-selection\">Machine Selection for Baby Bottle Production<\/a><\/li>\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#mould-design\">Mould Design for Baby Bottles<\/a><\/li>\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#quality\">Quality Testing for Baby Bottle Compliance<\/a><\/li>\n<li><a style=\"color: #0066cc; text-decoration: none;\" href=\"#conclusion\">\u0928\u093f\u0937\u094d\u0915\u0930\u094d\u0937<\/a><\/li>\n<\/ol>\n<\/nav>\n<p><!-- FIGURE 1 --><\/p>\n<figure style=\"margin: 0 0 44px; text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-67\" style=\"width: 100%; height: auto; display: block; border-radius: 8px; box-shadow: 0 4px 22px rgba(0,51,102,0.13);\" src=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/types-of-bottle-1.webp\" alt=\"BPA-free baby bottle manufacturing \u2014 Tritan PETG PC baby bottles wide-neck infant bottles produced by ISBM injection stretch blow moulding machine\" width=\"1024\" height=\"1536\" srcset=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/types-of-bottle-1.webp 1024w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/types-of-bottle-1-980x1470.webp 980w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/types-of-bottle-1-480x720.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><figcaption style=\"font-size: 13px; color: #556; margin-top: 10px; font-family: Arial,sans-serif; font-style: italic; line-height: 1.6;\">Figure 1 \u2014 Baby bottle formats produced by ISBM: standard-neck 150\u2013330 ml feeding bottles in Tritan or PETG, wide-neck 150\u2013240 ml slow-flow bottles for transition feeding, and specialty formats including storage bottles and sippy-cup bodies.

Its commercial success rests on four properties that address both the regulatory and practical requirements of the baby bottle market simultaneously:<\/p>\n<ul style=\"padding-left: 24px; line-height: 2.1; font-family: Arial,sans-serif; font-size: 15px;\">\n<li><strong>BPA-free by composition<\/strong> \u2014 Tritan does not use bisphenol A as a monomer at any stage of its synthesis. This is a structural material property, not a processing achievement; it holds regardless of the production conditions or supplier.<\/li>\n<li><strong>Glass transition temperature ~98 \u00b0C<\/strong> \u2014 Tritan maintains its shape in dishwashers (typically 60\u201370 \u00b0C cycle temperature) and in microwave sterilisation, unlike PETG (T<sub>\u091c\u0940<\/sub> ~80 \u00b0C) which softens under sustained high-temperature cleaning.<\/li>\n<li><strong>High impact resistance<\/strong> \u2014 Tritan&#8217;s toughness is significantly higher than both PET and PETG at equivalent wall gauge. Drop impact resistance \u2014 which defines the survival rate of bottles falling from feeding chairs and changing tables \u2014 is a critical consumer performance requirement for baby bottles, and Tritan delivers it consistently.<\/li>\n<li><strong>Glass-like optical clarity<\/strong> \u2014 Tritan produces haze values below 0.5% in ISBM-blown bottles, matching PETG&#8217;s clarity performance and substantially exceeding PET.<\/li>\n<\/ul>\n<p>The processing challenge specific to Tritan is its sensitivity to barrel temperature variation. If the barrel temperature in any zone exceeds the target by more than \u00b12\u20133 \u00b0C, Tritan begins to yellow \u2014 a colour change that is immediately visible in the finished bottle and constitutes a rejection. Because yellowing is caused by thermal degradation at a molecular level, it cannot be corrected by downstream processing; the degraded material must be purged and the batch scrapped. The \u00b11 \u00b0C barrel temperature control that the ISBM machine&#8217;s PID-controlled barrel heating system must maintain for Tritan production is therefore a hard machine requirement, not a performance aspiration.<\/p>\n<h3 style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(16px,2vw,19px); font-weight: bold; color: #004a99; margin: 28px 0 10px;\">PETG \u2014 The BPA-Free Mid-Tier Option<\/h3>\n<p>PETG (glycol-modified polyethylene terephthalate) is the BPA-free resin most widely used in mid-tier baby bottles \u2014 Korean domestic brands, private-label for retail, and markets where Tritan&#8217;s premium cost is a commercial constraint. PETG&#8217;s optical clarity is comparable to Tritan (haze below 0.5% in well-processed ISBM bottles) and its chemical resistance to cleaning agents and sterilisation solutions is good. Its primary limitation for baby bottles versus Tritan is its glass transition temperature \u2014 at T<sub>\u091c\u0940<\/sub> \u2248 80 \u00b0C, PETG baby bottles are not recommended for repeated dishwasher cycles at temperatures above 65\u201370 \u00b0C, as sustained thermal exposure can cause slight dimensional distortion in the bottle neck finish. For parents using hand-washing or cold sterilisation (cold-water sterilising tablets), PETG performs entirely adequately; for parents relying on dishwasher or steam steriliser cycles at 60\u201370 \u00b0C, Tritan is the more durable choice.<\/p>\n<h3 style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(16px,2vw,19px); font-weight: bold; color: #004a99; margin: 28px 0 10px;\">PC (Polycarbonate) \u2014 Technically Superior, Commercially Declining<\/h3>\n<p>Polycarbonate was the original premium baby bottle resin \u2014 clear, rigid, autoclave-compatible, and highly impact-resistant. Its T<sub>\u091c\u0940<\/sub> of approximately 147 \u00b0C makes it the most thermally stable of the three resins in daily use, and its optical clarity is exceptional. The problem is structural: PC is synthesised from bisphenol A (BPA), and while BPA migration from properly processed PC into food is extremely small (typically below detection limits in routine testing), the public perception of BPA risk in infant products has effectively eliminated PC from the consumer baby bottle market in Korea, Japan, and all Western markets. PC baby bottles remain in use in some professional medical and neonatal settings where autoclave sterilisation is required and the risk profile has been formally assessed \u2014 but for commercial baby bottle manufacturing targeting consumer markets, PC is no longer a viable resin choice regardless of the regulatory compliance data.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-202\" src=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/bottle-5.webp\" alt=\"\u092c\u094b\u0924\u0932-5\" width=\"1536\" height=\"1024\" srcset=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/bottle-5.webp 1536w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/bottle-5-1280x853.webp 1280w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/bottle-5-980x653.webp 980w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/bottle-5-480x320.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1536px, 100vw\" \/><!-- \u2550\u2550 H2 \u00a73 \u2014 PROCESSING \u2550\u2550 --><\/p>\n<h2 id=\"processing\" style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(21px,2.9vw,30px); font-weight: 800; color: #003366; margin: 52px 0 16px; padding: 14px 0 12px; border-bottom: 3px solid #0066cc;\">Processing Requirements \u2014 What Changes for Each Resin<\/h2>\n<p>The processing conditions required for Tritan, PETG, and PC in an <a href=\"https:\/\/isbm-blow-molding.com\/hi\/product-category\/4-station-isbm-machine\/\">\u0906\u0908\u090f\u0938\u092c\u0940\u090f\u092e \u092e\u0936\u0940\u0928<\/a> are sufficiently different that a machine configured for one resin cannot run another without parameter changes \u2014 and in some cases, the machine must have specific hardware options fitted to process the target resin reliably.

PETG tolerates \u00b12\u20133 \u00b0C variation across the barrel zones without visible quality impact in most production contexts. Tritan does not: a single zone running 3\u20134 \u00b0C above target for more than a few cycles produces visibly yellow-tinted preforms that will appear as yellow-cast baby bottles \u2014 a quality failure that is immediately detectable by any parent and will result in brand rejection.<\/p>\n<p>The ISBM machine&#8217;s barrel temperature control system must use PID-controlled zone heaters with thermocouple feedback capable of maintaining setpoint to \u00b11 \u00b0C under production conditions (not just at steady-state idle). Korea Ever-Power&#8217;s HGY series machines meet this requirement across all barrel zones; buyers considering alternative suppliers should specifically request barrel temperature stability data under continuous production conditions, not just thermocouple accuracy specifications.<\/p>\n<p><!-- \u2550\u2550 H2 \u00a74 \u2014 WHY ISBM \u2550\u2550 --><\/p>\n<h2 id=\"why-isbm\" style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(21px,2.9vw,30px); font-weight: 800; color: #003366; margin: 52px 0 16px; padding: 14px 0 12px; border-bottom: 3px solid #0066cc;\">Why ISBM Is the Right Process for Baby Bottles<\/h2>\n<p>Baby bottles could theoretically be produced by two-step reheat blow moulding \u2014 but in practice, the application requirements push almost all premium baby bottle production toward one-step ISBM. Three specific characteristics of the one-step process align directly with baby bottle production requirements:<\/p>\n<h3 style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(16px,2vw,19px); font-weight: bold; color: #004a99; margin: 28px 0 10px;\">No Preform Storage \u2014 No Contamination Window<\/h3>\n<p>In two-step blow moulding, preforms are stored in bulk containers (gaylords) between injection and blowing \u2014 sometimes for hours, sometimes for days, in an uncontrolled environment. For standard beverage bottles, this is accepted as a practical production reality. For baby bottles, where the finished container may be in direct extended contact with infant formula at body temperature for hours each day, the contamination risk introduced by bulk preform storage \u2014 airborne particles, surface contact with other preforms, potential cross-contamination from adjacent materials \u2014 is a quality and regulatory exposure that many baby bottle brands refuse to accept.<\/p>\n<p>ISBM&#8217;s one-step closed-loop process eliminates this exposure window entirely. The preform is injected and blown in the same machine, in the same cycle, without external handling. The bottle exits the machine having had contact only with the precision-machined mould surfaces and the process air \u2014 a dramatically shorter and more controlled contamination pathway than two-step production.<\/p>\n<h3 style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(16px,2vw,19px); font-weight: bold; color: #004a99; margin: 28px 0 10px;\">GMP-Compatible Electric Drive \u2014 Critical for Certified Production<\/h3>\n<p>Baby bottle manufacturers targeting regulated markets (Korea MFDS, EU, FDA) frequently operate in controlled production environments \u2014 not necessarily full ISO-classified cleanrooms, but areas with defined environmental monitoring, no hydraulic oil contamination sources, and documented equipment qualification. The fully electric ISBM machine&#8217;s oil-free architecture is directly compatible with this controlled environment requirement. The hydraulic machine&#8217;s oil contamination risk, while manageable in a standard production setting, introduces a contamination source that complicates GMP compliance documentation and requires ongoing monitoring to verify absence of oil on product surfaces.<\/p>\n<p><!-- \u2550\u2550 H2 \u00a75 \u2014 MACHINE SELECTION \u2550\u2550 --><\/p>\n<h2 id=\"machine-selection\" style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(21px,2.9vw,30px); font-weight: 800; color: #003366; margin: 52px 0 16px; padding: 14px 0 12px; border-bottom: 3px solid #0066cc;\">Machine Selection for Baby Bottle Production<\/h2>\n<p><!-- FIGURE 3 --><\/p>\n<figure style=\"margin: 0 0 26px; text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-342\" style=\"width: 100%; height: auto; display: block; border-radius: 8px; box-shadow: 0 4px 22px rgba(0,51,102,0.13);\" src=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/Injection-Stretch-Blow-Moulding-Machine-application-1-2.webp\" alt=\"ISBM machine for baby bottle manufacturing \u2014 Korea Ever-Power HGY series producing Tritan PETG BPA-free baby bottles in cleanroom environment\" width=\"1935\" height=\"1088\" srcset=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/Injection-Stretch-Blow-Moulding-Machine-application-1-2.webp 1935w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/Injection-Stretch-Blow-Moulding-Machine-application-1-2-1280x720.webp 1280w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/Injection-Stretch-Blow-Moulding-Machine-application-1-2-980x551.webp 980w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/Injection-Stretch-Blow-Moulding-Machine-application-1-2-480x270.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1935px, 100vw\" \/><figcaption style=\"font-size: 13px; color: #556; margin-top: 10px; font-family: Arial,sans-serif; font-style: italic; line-height: 1.6;\">Figure 3 \u2014 Korea Ever-Power HGY series ISBM machine in baby product manufacturing.

Standard beverage and cosmetic bottles use neck finishes of 18\u201348 mm outer diameter; baby bottles use neck finishes of 50\u201372 mm to accommodate the silicone nipple sleeve and its mounting ring. The two dominant market standards are:<\/p>\n<div style=\"display: grid; grid-template-columns: repeat(auto-fit,minmax(min(100%,240px),1fr)); gap: 12px; margin: 14px 0 24px; font-family: Arial,sans-serif;\">\n<div style=\"background: #f7faff; border-radius: 7px; padding: 15px 17px; border-left: 4px solid #0066cc;\">\n<p style=\"font-size: 13px; font-weight: 800; color: #003366; margin: 0 0 7px;\">Wide-Neck Standard \u2014 &#8220;Avent-Style&#8221;<\/p>\n<p style=\"font-size: 13.5px; color: #1a2030; margin: 0; line-height: 1.72;\"><strong>Neck OD: ~61\u201363 mm<\/strong><br \/>\nUsed by Philips Avent, Medela, and numerous Korean and Asian baby bottle brands. The large neck diameter allows the nipple sleeve to be positioned further from the bottle axis, reducing the &#8220;dead space&#8221; of unused formula trapped around the nipple base. Preferred for wide-mouth feeding that reduces infant ingestion of air.<\/p>\n<\/div>\n<div style=\"background: #f7faff; border-radius: 7px; padding: 15px 17px; border-left: 4px solid #0066cc;\">\n<p style=\"font-size: 13px; font-weight: 800; color: #003366; margin: 0 0 7px;\">Standard-Neck Wide \u2014 &#8220;NUK-Style&#8221;<\/p>\n<p style=\"font-size: 13.5px; color: #1a2030; margin: 0; line-height: 1.72;\"><strong>Neck OD: ~52\u201355 mm<\/strong><br \/>\nUsed by NUK, Munchkin, and brands targeting a narrower nipple geometry for a more natural feeding position. This neck finish is smaller than Avent-style but still significantly larger than standard pharmaceutical or cosmetic bottle necks, requiring dedicated wide-neck preform tooling and appropriate injection clamping force.<\/p>\n<\/div>\n<\/div>\n<p>The wide-neck finish creates a specific injection clamping force requirement. A 61 mm neck finish preform cavity has a projected area approximately 8\u201310\u00d7 larger than a standard 20 mm pharmaceutical preform cavity. At 160 MPa injection pressure, this produces a mould-opening force of 47\u201350 kN \u2014 which approaches the HGY50&#8217;s 50 kN injection clamp limit on a 1-cavity tool. A 2-cavity wide-neck tool at 61 mm neck would require approximately 95\u2013100 kN of injection clamping, which exceeds the HGY50 entirely and requires the HGY150-V3&#8217;s 150 kN injection clamp. Wide-neck baby bottle mould design always requires a clamping force calculation based on the actual neck finish projected area before the machine platform is selected.<\/p>\n<h3 style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(16px,2vw,19px); font-weight: bold; color: #004a99; margin: 28px 0 10px;\">Drop Resistance Design \u2014 Engineering the Bottle to Survive a Metre Drop<\/h3>\n<p>Baby bottles are dropped \u2014 repeatedly, from feeding chairs, changing tables, and infant car seats, at heights of 0.6\u20131.0 m onto hard floor surfaces. The bottle must survive this abuse without cracking, because a cracked baby bottle in service is a safety hazard: it can produce sharp plastic edges, allow formula contamination, or \u2014 on impact \u2014 cause the contents to spray onto the infant.<\/p>\n<p>Drop resistance is not achieved by increasing wall thickness alone \u2014 it is engineered through specific geometric choices in the bottle and mould design:<\/p>\n<ul style=\"padding-left: 24px; line-height: 2.1; font-family: Arial,sans-serif; font-size: 15px;\">\n<li><strong>Rounded shoulder transition:<\/strong> Sharp shoulder radii concentrate impact stress at the shoulder-to-body transition \u2014 the most common crack initiation point in drop testing. A shoulder radius of 15\u201325 mm (large relative to the bottle body diameter) distributes the impact force across a larger material volume, delaying crack initiation. Baby bottle moulds for Tritan and PETG routinely specify shoulder radii of 18\u201322 mm even on bottles where aesthetics would favour a sharper shoulder.<\/li>\n<li><strong>Reinforced base dome:<\/strong> The base dome is the primary impact surface in a vertical drop and the secondary impact surface in a horizontal drop. A base dome thickness 20\u201330% greater than the body wall gauge, combined with a slightly convex dome profile rather than a flat base, distributes impact loading through the dome&#8217;s curvature rather than concentrating it at a flat centre point.<\/li>\n<li><strong>Uniform body wall:<\/strong> Wall thickness variation in the body creates stress concentration at thin spots under impact. A body wall that varies by more than \u00b10.05 mm across a circumferential cross-section will consistently fail at the thinnest point in drop testing. This is why ISBM&#8217;s wall thickness consistency \u2014 typically \u00b10.04 mm from a well-designed tool \u2014 is a structural advantage in baby bottle production that is directly reflected in drop test survival rates.<\/li>\n<\/ul>\n<p><!-- \u2550\u2550 H2 \u00a77 \u2014 QUALITY \u2550\u2550 --><\/p>\n<h2 id=\"quality\" style=\"font-family: 'Helvetica Neue',Arial,sans-serif; font-size: clamp(21px,2.9vw,30px); font-weight: 800; color: #003366; margin: 52px 0 16px; padding: 14px 0 12px; border-bottom: 3px solid #0066cc;\">Quality Testing for Baby Bottle Compliance<\/h2>\n<p><!-- FIGURE 4 --><\/p>\n<figure style=\"margin: 0 0 26px; text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-190\" style=\"width: 100%; height: auto; display: block; border-radius: 8px; box-shadow: 0 4px 22px rgba(0,51,102,0.13);\" src=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/certificatification-1.png\" alt=\"Korea Ever-Power ISBM machine certifications \u2014 quality testing for Tritan PETG BPA-free baby bottle manufacturing compliance\" width=\"1536\" height=\"1024\" srcset=\"https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/certificatification-1.png 1536w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/certificatification-1-1280x853.png 1280w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/certificatification-1-980x653.png 980w, https:\/\/isbm-blow-molding.com\/wp-content\/uploads\/2026\/02\/certificatification-1-480x320.png 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1536px, 100vw\" \/><figcaption style=\"font-size: 13px; color: #556; margin-top: 10px; font-family: Arial,sans-serif; font-style: italic; line-height: 1.6;\">Figure 4 \u2014 Quality certification and testing for baby bottle production.
