Plastic Cap

1. Airtight & Leak-Proof Seal
   Precision-molded threads plus an inner liner (EPE, silicone seal or induction foil) lock out air and moisture, extending serum, lotion or essence shelf life and preventing travel leaks.
2. Controlled Grip & Ergonomics
   Vertical ribs around the skirt give wet or product-coated fingers extra friction, enabling smooth one-handed opening and firm re-closure without slippage.
3. Visual Inventory & Color Matching
   Crystal-clear resin lets consumers and retailers instantly see remaining product level and true color, reducing guesswork and returns.
4. Premium “Clean Beauty” Aesthetic
   Transparency conveys purity and minimalism, complementing frosted or clear glass bottles and supporting high-end skincare branding.
5. Universal Compatibility
   Standard 30mm neck sizes fit most PET, HDPE or glass skincare bottles, simplifying procurement and inventory.
6. Decoration & Branding Canvas
   Smooth crown area accepts silk-screen logos, metallic hot-stamps or seasonal stickers without obscuring the ribs; ribs themselves can be color-tinted for subtle accents.
7. Chemical & UV Resistance
   Clarified PP or PET resists essential oils, acids, alcohols and mild UV exposure, maintaining clarity and preventing stress-cracking.
8. Lightweight, Recyclable & Cost-Efficient
   Single-material construction (<2 g) reduces freight cost and is fully recyclable, aligning with sustainability goals while keeping a premium look.
