Korean liquid foundation IBM formulations require ABS compatibility verification for three ingredient categories. First, high silicone content: Korean full-coverage foundation at 15-25% dimethicone or phenyl trimethicone requires a 40°C/90-day accelerated compatibility test — silicone fluids at 15%+ can cause surface interaction with ABS (slight gloss reduction at the interior body contact zone) over 18-24 months. For Korean foundation ABS IBM, verify that interior body gloss does not visually degrade at the silicon contact zone at 18-month simulation — exterior body gloss (what the Korean consumer sees) is unaffected by interior contact. Second, fragrance loading: Korean foundation at 0.5-2% fragrance (benzyl alcohol, linalool esters) can reduce ABS surface hardness slightly at extended fill contact. Verify ABS surface hardness (Shore D) at 40°C/90 days for Korean high-fragrance foundation formulations. Third, preservatives at higher concentration: phenoxyethanol at 0.5-1.0% is compatible with ABS; methylisothiazolinone (MIT) at 0.01-0.05% in Korean preservative-minimal foundation is compatible; parabens at 0.1-0.4% are compatible with ABS at Korean foundation usage concentrations. For Korean natural and organic foundation formulations using non-standard preservative systems (sodium benzoate, potassium sorbate), Korea Ever-Power recommends a 40°C/90-day ABS IBM container compatibility test before Korean MFDS cosmetic registration, as novel preservative systems may not have existing Korean ABS IBM compatibility data available from the Korean ABS resin supplier’s technical reference library.

Korean luxury foundation matte black ABS IBM requires a specific masterbatch formulation that produces a deep matte black surface without the surface sheen that standard carbon black masterbatch produces on ABS. The matte black ABS IBM production protocol at Korea Ever-Power: (1) use a Korean cosmetic-grade carbon black masterbatch (carbon black <100 nm particle size, at 0.5-1.0% loading in ABS carrier) for deep, uniform black coverage — higher carbon black loading (above 1.0%) starts to show surface reflectivity variations; (2) add a matting agent (silica-based matting agent at 0.5-1.5% loading) to the ABS masterbatch blend to achieve the matte surface texture that Korean luxury foundation brands specify for their premium packaging design; (3) run at mould temperature 55-65°C (slightly lower than glossy ABS IBM) to allow the silica matting agent to create the required micro-texture surface; (4) verify the matte surface effect at 500 lux under 45-degree directional light — Korean luxury foundation brand acceptance: gloss reading 5-20 GU at 60 degrees (matte), ≤ 0.5 GU at 85 degrees (very low reflected sheen). Korea Ever-Power maintains matte black ABS IBM as a standard production capability for Korean luxury foundation and Korean luxury face cream jar applications.

Korean luxury foundation IBM bottles use four primary decoration techniques, all compatible with IBM’s flat body surfaces and zero parting line exterior. Hot stamp foiling: the most common Korean luxury foundation bottle decoration — Korean brand logo, product name and luxury visual mark stamped in gold, silver or holographic foil on the ABS IBM body flat zone. IBM body surface stability (no thermal warpage at 60-80°C hot stamp die temperature) ensures clean Korean foil transfer without adhesion failure. Screen printing: applied to the ABS IBM body for Korean brand identification and shade number printing. ABS IBM surface (Ra 0.4-0.8 um at body) achieves ceramic ink adhesion without primer or corona for most Korean UV-curable ink systems — verify adhesion with Korean cosmetic contract printing partner for specific ink systems. In-glaze printing (silk screen with UV ink): applied after hot stamp for Korean foundation shade range multi-colour text. UV coating: Korean luxury foundation ABS IBM bottles sometimes receive a UV topcoat over the hot stamp to provide abrasion resistance and chemical resistance against cosmetic contamination — UV coating over ABS IBM achieves excellent adhesion without adhesion promoter. Laser engraving: Korean luxury foundation brands use laser engraving of the ABS IBM body for Korean brand serial number, Korean expiry date and Korean product batch code — ABS IBM laser engraving produces clean Korean alphanumeric marks at 0.2-0.4 mm depth without mechanical surface damage.

Korean luxury foundation IBM project lead time from project initiation to first Korean commercial production delivery on Korea Ever-Power’s ZQ40 follows a standardised timeline. Design confirmation (3-4 weeks): Korea Ever-Power applications engineering reviews Korean brand’s container design drawings, confirms preform wall engineering for the airless pump body bore requirement and produces the IBM container specification drawing for Korean brand approval. Mould design and fabrication (10-12 weeks): injection mould (S136 stainless, mirror polish), blow mould (P20 steel, Ra 0.025 um mirror finish), stripping tool machined and assembled. Blow mould corner EDM for angular body designs adds approximately 1-2 weeks to standard round body mould fabrication. Pre-delivery production trial (1 week): ZQ40 ABS IBM production trial at Korea Ever-Power Ansan-si facility, producing 300-500 container samples per cavity. ABS drying protocol, process parameter optimisation, 100% appearance inspection at 500 lux, dimensional measurement (all 6 dimensions per cavity), airless pump fitment verification using Korean brand-supplied Korean airless pump assembly. Documentation package (1 week): Korea Ever-Power issues dimensional report, ABS material declaration, process declaration and mould maintenance protocol. Total lead time from project initiation to first Korean commercial production delivery: 16-19 weeks. For Korean luxury foundation launch season planning: Korea Ever-Power recommends confirming the Korean IBM container project at minimum 20 weeks before Korean brand launch date to allow for design revision cycles and production trial repeat if Korean brand requests specification changes after initial production trial review.
