Glass-Look PCTG Bottles
\nby Injection Blow Molding<\/span>:
\nAchieving Sub-2% Haze for K-Beauty<\/h1>\n

PCTG injection blow molded bottles with S136 SPI A1 mould tooling achieve 0.8\u20131.6% ASTM D1003 haze across all 30 cavity positions \u2014 meeting the sub-2% optical threshold that Korean luxury K-beauty dropper vial and serum bottle brands specify as the glass-look equivalence criterion. This guide covers the physics of IBM bottle optical clarity, the complete S136 SPI A1 tooling specification, validated process parameters for Eastman PCTG TX1001, and production economics at Korea Ever-Power EP-ZQ135.<\/p>\n

HAZE ACHIEVED<\/p>\n

0.8\u20131.6%<\/p>\n

ASTM D1003 integrating sphere method at 0.5\u20130.6 mm body wall, PCTG Eastman TX1001, S136 SPI A1 mould (Ra \u22640.010 \u03bcm), 18\u201322\u00b0C blow mould cooling, EP-ZQ135. Consumer glass-look perception threshold: <3% haze. Sub-2% = luxury glass-look equivalence for Korean premium K-beauty dropper vial and serum bottle.<\/p>\n<\/div>\n

\n

MOULD STEEL<\/p>\n

S136 SPI A1<\/p>\n

S136 stainless steel (HRC 50\u201354) polished to SPI A1 surface finish (Ra \u22640.010 \u03bcm, equivalent to #3 diamond buff). Standard H13 SPI B1 tooling achieves Ra 0.05\u20130.10 \u03bcm and haze 3\u20138% \u2014 above the 2% luxury threshold. S136 SPI A1 adds 35\u201350% mould cost vs H13 SPI B1; justified at K-beauty luxury retail margin (1,500\u20138,000 KRW per bottle).<\/p>\n<\/div>\n

\n

PEAK CAVITY OUTPUT<\/p>\n

30 @ 10 ml<\/p>\n

EP-ZQ135 confirmed 30 cavities at 10 ml PCTG dropper vial (1,300 mm platen, 38 mm pitch). Annual output: approximately 428 million crystal-clear dropper vials per EP-ZQ135 unit at 5.0 s cycle, 3 shifts, 330 days. Highest single-machine K-beauty IBM output with sub-2% haze specification.<\/p>\n<\/div>\n

\n

VS GLASS ECONOMICS<\/p>\n

40\u201360%<\/p>\n

Lower cost per unit for PCTG IBM vs moulded glass dropper vials at equivalent luxury K-beauty 10 ml format. Break-even with glass tooling investment recovered in 3\u20136 months at Korean K-beauty contract manufacturing (CMO) production scale. PCTG IBM also lighter (\u221260% vs glass), drop-safe, and BPA-free.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
