Korean MFDS Cosmetic Regulation (Korean Cosmetics Act and Enforcement Decree) applies to ABS eye cream jar containers. ABS is classified as a cosmetic container material in the Korean MFDS Standards for Cosmetic Containers — it is listed as an acceptable cosmetic primary container material with the restriction that it must not contain heavy metals above Korean MFDS limits (lead <100 ppm, cadmium <75 ppm in the total polymer including additives and colourants) and that it must not transfer restricted chemicals to the cosmetic product contents above Korean MFDS cosmetic migration limits. For Korean ABS eye cream jar IBM: (1) specify Korean MFDS cosmetic-grade ABS from Korean MFDS registered additive-clean Korean ABS supplier; (2) confirm colourant is Korean MFDS cosmetic positive list pigment (titanium dioxide, iron oxides, organic pigments on Korean positive list); (3) confirm no recycled ABS content — Korean MFDS cosmetic container regulations require new (virgin) polymer for direct cosmetic contact containers. Korea Ever-Power provides ABS material declaration documentation for Korean MFDS cosmetic registration as part of the IBM container qualification package.

Korean luxury cosmetic brand gloss specifications for IBM eye cream jars are measured using a specular gloss meter at 60-degree measurement geometry (ASTM D523 or ISO 2813). The 60-degree geometry is the standard for medium-to-high gloss surfaces — producing gloss unit (GU) readings that correlate with the visual gloss impression of the ABS jar exterior under Korean department store display lighting. Korean luxury eye cream IBM jar gloss specification: 85-95 GU at 60 degrees. This range corresponds to a near-mirror high-gloss finish that Korean consumers associate with premium cosmetic packaging quality. ABS HG (high-gloss) grade IBM at Ra 0.05 um blow mould cavity polish consistently achieves 88-95 GU on the jar body exterior — within specification with adequate margin. Korea Ever-Power measures gloss on production trial jars at 5 positions (top, bottom, left, right, centre of body exterior) per cavity, and requires all measurements above 85 GU before issuing dimensional approval to the Korean luxury eye cream brand.

Yes — ABS and PP can both run on the same ZQ40 machine with mould set changeover between production runs. The barrel temperature adjustment between ABS (210-240°C) and PP (210-245°C) is minimal and does not require a significant machine warm-up period when switching. The critical changeover protocol when switching from ABS to PP: purge the barrel with PP at PP processing temperature before starting PP production to clear ABS residue, which would contaminate the initial PP jars with ABS flecks. The purge protocol requires 3-5 barrel shots of PP until the output shows clean, consistent PP colour before production starts. Switching from PP to ABS requires: (1) purge PP from barrel with ABS at ABS temperature; (2) confirm desiccant dryer ABS is adequately dried before introducing ABS to the barrel; (3) run 5-10 startup shots and inspect for silver streaks before declaring production quality. The mould temperature adjustment from PP (55-70°C for cosmetic PP IBM) to ABS (55-70°C for ABS IBM) is identical for cosmetic applications — no mould temperature adjustment is needed when switching between cosmetic ABS and cosmetic PP on the same ZQ40.

ABS IBM eye cream jar compatibility with Korean eye cream formulations is generally excellent — Korean eye cream formulations at neutral to mildly acidic pH (5.0-7.5) with emollient, humectant and active ingredient systems do not attack the ABS polymer structure at usage concentrations. Three ingredient categories require specific verification for Korean ABS eye cream IBM containers. First, aromatic solvents: Korean eye cream formulations containing benzyl alcohol (preservative at 0.5-1.5%) or phenoxyethanol (preservative at 0.5-1.0%) can cause slight ABS surface softening at extended contact in a sealed container over 18-24 months — verify by sealed compatibility test at 40°C/90 days for Korean eye cream formulations containing these preservatives above 0.5%. Second, high-concentration retinol or vitamin C derivatives: retinol at 0.3-1.0% in Korean prescription-level eye cream formulations is mildly oxidising and can produce slight yellowing of ABS surface at the formulation contact zone over time. Third, silicone-based eye cream: silicone fluid (dimethicone, cyclopentasiloxane) at high concentration (>30%) in Korean silicone-based eye cream can act as a plasticiser for ABS, causing slight gloss reduction at the interior surface contact zone. For most standard Korean eye cream formulations (aqueous emulsions with peptide actives, hyaluronic acid, niacinamide), ABS IBM containers are fully compatible for 24-month Korean luxury cosmetic shelf life without special compatibility testing beyond standard Korean MFDS cosmetic container migration testing.
