Cap surface without hole, the gas flow through the gasket groove back directly, by thread clearance within the cap air exchange.
Deformation and seepage problem, can be used to solve the packaging container keep container inside and outside pressure balance, to prevent deformation, expansion, absorption and leak container.
Breathable gasket application which can effectively prevent liquid leakage, ensure continuous container gas exchange inside and outside at the same time, even if the container filling organic matter, surfactants, oils, or solvents.
Breathable spacer allows end users to choose a smaller wall thickness, the minimum weight packaging container;
Breathable spacer can minimize the container costs and procurement costs, reduce processing costs at the same time;
Breathable spacer can be widely used a variety of sizes and specifications of the gasket thickness, can simply instead。
