The L203B is a black polypropylene (PP) plastic lid with a 43-400 neck finish and a smooth skirt design. It features a pressure-sensitive (PS) liner made from foamed polystyrene that adheres to the bottle's landing when the lid is affixed. The high heat tolerance and fatigue resistance of PP make this lid durable and reliable for various packaging needs.

This closure offers efficiency by securely sealing containers and ensuring product integrity. It is compatible with bottles requiring a 43-400 neck finish, commonly used in industries like pharmaceuticals, chemicals, and food & beverage. The pressure-sensitive liner provides a tight seal, safeguarding contents from leaks or contamination during storage and transportation.

Shipping with this lid is hassle-free, and its commercial advantages include enhancing product shelf life and maintaining freshness. The PS liner ensures a secure seal until the lid is removed for dispensing, contributing to a professional packaging solution. Ideal for businesses seeking reliable packaging solutions, the L203B lid is a practical choice for streamlining operations and delivering quality products to customers.
