Standard plastic thermoformed cups often allow moisture vapor transmission over 6–12 months, causing kaolin/bentonite clay to solidify. Yanmei uses co-extruded high-barrier thermoforming films (PP/EVOH/PE) paired with multi-layer heat-seal aluminum foil lidding. EVOH (Ethylene Vinyl Alcohol) provides a near-zero Oxygen Transmission Rate (OTR < 0.1 cc/m2·day) and Water Vapor Transmission Rate (WVTR < 0.1 g/m2·day), maintaining optimal paste plasticity for 24 months. --- ### Q2: What are break-to-use card packs and why are they surging in DTC subscription boxes? Break-to-use (one-hand snap) card packs feature a rigid backing with a micro-perforated central fold line. When folded with one hand, the internal membrane bursts outward, dispensing 1.0ml–3.0ml of serum or lotion cleanly without tearing or messy fingertips. Measuring less than 2mm in thickness, they fit inside standard envelope direct mailers (saving 70% shipping postage compared to bulky bottles) and slide easily into monthly subscription boxes like Ipsy or Birchbox. --- ### Q3: Can active chemical peels (AHA/BHA) be safely filled into Yanmei beauty pods? Yes. Highly acidic active treatments (such as 10% Glycolic Acid or 2% Salicylic Acid at pH 3.5) will degrade low-grade polyolefins. We conduct 30-day accelerated chemical compatibility stress tests using high-density inert polymer linings that resist ester leaching, swelling, or lidding delamination. --- ### Q4: What pod capacities and branding customizations are available? Capacities range from 3g, 5g, 8g to 15g. Customizations include dual-color cup injection, matte soft-touch exterior coating, debossed brand logos on the peel tab, and full-color CMYK high-definition foil lid printing. --- ### Q5: What is the typical sampling and pilot production turnaround? Standard formula samples with generic pod packaging dispatch in 3–5 business days. Custom printed prototypes with brand artwork take 7–10 days. Pilot production runs of 5,000 pods typically ship in 3 weeks following artwork confirmation. --- ## Contract Manufacturing Inquiries To request technical dossiers, formulation compatibility tests, and pilot batch quotes (MOQ 5,000 units): - **Direct Factory Email**: alex@yanmeicos.com - **Official RFQ Portal**: https://yanmeicos.com/contact.html - **Company Identity**: Yanmei Bio-Technology Co., Ltd.
