A 20-400 screw top cap with an LDPE (Low-Density Polyethylene) polycone liner is a reliable and widely used closure system designed to provide a secure and leak-proof seal for bottles with a 20mm neck size and 400 thread finish.
Components:
- Cap: The screw top cap, typically made from durable plastic, features a threaded design that allows it to be screwed onto compatible bottles securely. It usually has a ribbed exterior for easy gripping and handling.
- LDPE Polycone Liner: The polycone liner, made from low-density polyethylene, is a conical insert inside the cap. This liner compresses against the bottle’s neck, creating a tight seal that prevents leaks and preserves the integrity of the contents.
Features:
- Secure Seal: The LDPE polycone liner ensures a tight, leak-proof seal, protecting the bottle's contents from contamination and evaporation.
- Durability: The cap's robust plastic construction provides excellent resistance to impact, chemicals, and temperature variations.
- Compatibility: The 20-400 thread finish is designed to fit bottles with a 20mm neck size, ensuring a secure and consistent fit.
- Ease of Use: The ribbed exterior of the cap allows for easy opening and closing, even with wet or slippery hands.
