What is Plastic Dispensing Cap?

Plastic dispensing cap is plastic bottle cap with valve, also known as dispensing closure or squeeze bottle lid. The 38-400 plastic dispensing cap is a versatile dispensing closure developed for brands seeking a balance between functionality, durability, and cost efficiency. Manufactured using high-quality PP plastic injection molding technology, this bottle cap features a silicone valve insert that creates an effective sealing and dispensing system.

When the bottle is squeezed, pressure activates the silicone valve, allowing the product to flow smoothly through the opening. After dispensing, the valve immediately returns to its sealed position, reducing dripping and keeping the bottle opening clean.
