IBM vs EBM
\nfor K-Beauty Container<\/span>: Korean Cosmetic Packaging Guide<\/h1>\n

Korean K-beauty brands selecting a blow moulding process for cosmetic cream jars, lotion bottles, toner bottles and serum bottles face a key decision: IBM (Injection Blow Moulding) on Korea Ever-Power ZQ machines versus EBM (Extrusion Blow Moulding). The choice determines container surface quality, neck OD precision, parting line presence, material options and production economics for Korean cosmetic packaging programmes.<\/p>\n

IBM vs EBM FOR K-BEAUTY \u00b7 KEY DECISION FACTORS<\/p>\n<\/div>\n

\n
\n

PARTING LINE<\/p>\n

IBM: None<\/p>\n

IBM cosmetic containers have no parting line flash on the body or base \u2014 the blow mould seam is on the container base where it is not visible. EBM cosmetic containers have a visible parting line seam running the full length of the bottle body and across the base from the EBM mould pinch-off, requiring trimming and leaving a visible seam line on the K-beauty container<\/p>\n<\/div>\n

\n

NECK OD TOLERANCE<\/p>\n

IBM \u00b10.05mm<\/p>\n

IBM neck OD tolerance \u00b10.05mm (core rod controls neck geometry at all 3 IBM stations). EBM neck OD tolerance \u00b10.15\u20130.30mm (EBM neck is formed by the mould pinch-off and cannot match IBM core rod precision). For Korean K-beauty pump fitment (Aptar 24\/410, Yonwoo 28mm pump): IBM \u00b10.05mm is required for consistent Korean pump application torque; EBM \u00b10.15\u20130.30mm can cause Korean pump fitment variability at Korean cosmetic filling line<\/p>\n<\/div>\n

\n

MATERIAL OPTIONS<\/p>\n

IBM: PP, PCTG<\/p>\n

IBM: PP (opaque white, colour, pearl, metallic), PCTG (transparent crystal), HDPE. EBM: HDPE (primary EBM material for K-beauty: shampoo, body wash, sunscreen), LDPE (squeeze tubes), PP (EBM PP is possible but produces lower surface quality than IBM PP), PVC (declining in Korean cosmetic market). PP IBM is preferred over PP EBM for K-beauty premium cosmetic containers due to superior IBM surface quality and neck OD precision<\/p>\n<\/div>\n

\n

TOOLING INVESTMENT<\/p>\n

IBM Higher<\/p>\n

IBM cosmetic container mould investment (KRW 7\u201318M for 8\u201312 cavity IBM mould at Korea Ever-Power Ansan-si) is higher than EBM mould investment (KRW 2\u20136M for typical 4\u20138 cavity EBM cosmetic bottle mould). IBM tooling investment is justified for K-beauty premium cosmetic containers requiring no parting line, precise neck OD and PP monomaterial recyclability, at annual volumes above 200,000 pcs\/year<\/p>\n<\/div>\n<\/div>\n<\/div>\n
