Small Clear Round Ribbed Plastic Cap for Cosmetic Bottles

Plastic Cap

1. Hermetic Seal
   Internal liner or plug‐type land mates with the bottle finish to block air ingress and product egress, preventing evaporation, contamination and leakage.
2. Child-Resist / Tamper Evidence (when specified)
   Some versions incorporate a break-ring or ratchet bead that fractures upon first opening, giving visible proof of tampering while still fitting small, portable formats.
3. Grip & Ergonomics
   Fine vertical ribs (knurling) let wet or lotion-covered fingers maintain torque control during one-handed opening/closing.
4. Visual Inventory Check
   Crystal-clear resin allows consumers and retailers to see fill level, color shift, or phase separation without removing the closure—reducing returns and overstock.
5. Dropper / Pump Compatibility
   Short, low-profile skirt keeps overall height minimal so the cap can nest over a dropper bulb, orifice reducer, or fine-mist sprayer without looking oversized.
6. Chemical & UV Resistance
   Clarified PP or PET withstands essential oils, alcohols, and mild acids; optional UV-absorbing additives protect light-sensitive actives (e.g., vitamin C serums).
7. Decoration Canvas
   Smooth crown and ribs accept pad-printing, silk-screen, or hot-stamping for logos, batch codes, or color-coding without obscuring contents.
8. Lightweight & Recyclable
   <2 g closure lowers shipping cost and is mono-material (PP or PET) to simplify post-consumer recycling streams.
