Product Introduction
The Grooved Surface BL-215G Polyethylene Foam Breathable Gasket is a single-piece bottle cap liner. It is composed of a 1.5mm-thick polyethylene foam liner full of breathable holes and a PTFE breathable membrane with excellent corrosion resistance and hydrophobicity. It provides reliable sealing for products in bottles such as pesticides, fertilizers, and disinfectants that are prone to generating gas and causing bottle expansion. While blocking the penetration of the products, it allows the gas generated by the products in the container to be released, to prevent the gas from damaging the container's sealing performance and causing leakage accidents. The foam surface of the Grooved Surface BL-215G Polyethylene Foam Breathable Gasket is covered with grooves, which increases the air permeability to meet higher air permeability requirements.
