The breathable gasket is developed to prevent the plastic bottle (barrel) from being filled with a certain liquid in the shaking state, or placed at different temperatures, producing gas, which causes the plastic bottle (barrel) to deform or crack the cap.

The “breathable gasket” is composed of a grooved PE gasket and a polymer breathable film, which fully achieves the effect of “breathable without leakage”.

Function: It mainly regulates the internal and external pressure of the bottle to prevent the danger of bottle expansion. Its function also has the hydrophobic and breathable function (to prevent the flow of internal and external liquid, but it can make the gas discharge) The breathable gasket is light and simple. The size and shape design change is simple and indirectly reduces the requirements of the bottle and the bottle cap.

PE foam gaskets usually have the following characteristics: Light weight: PE foam gaskets are made of polyethylene material, so they are light in weight. Durability: Good tear resistance and wear resistance. Good buffer performance: can provide good buffer protection, can reduce the impact of external impact on the packaging of goods. Thermal insulation: PE foam gasket has a certain thermal insulation performance, suitable for packaging items that need to maintain temperature. Waterproof and moisture-proof: Under normal circumstances, PE foam gasket has a certain waterproof and moisture-proof performance, which can protect the packaged items from moisture. These characteristics make PE foam gaskets widely used in packaging and protection fields.
