(Summary description)

Breathable gaskets and vent plugs for packaging are mainly used for fertilizers, fermented liquids, peroxides and other solid and liquid packaging materials that can release or decompose gases. The main function is to not only leak, but also to ensure the pressure balance inside and outside the packaging. , Improve the safety, use time and stability of the packaging. ,

In the choice of the breathable gasket and the breathable membrane in the breathable plug for packaging, for water and ordinary liquid fertilizers, only need to choose a breathable membrane material with a certain water blocking ability and air permeability, but the surface tension of the liquid is relatively low. For products such as oils, solvents, flavors, surfactants, peroxides, formic acid and other liquids, ordinary breathable membrane materials are completely unsuitable, because liquids with low surface tension are very easy to penetrate the breathable membranes, causing the membrane pores to be blocked. It is breathable, loses its function, and leaks in a large area. Chuangcheng Technology has mastered the treatment technology against low surface tension liquids (the market is collectively referred to as oil-repellent treatment, and the breathable film that resists low surface tension liquids is called oil-repellent film).

The oil-proof breathable film has a wider application range in packaging. Not only ordinary liquids can be applied, but also the various low surface tension liquids mentioned above can be applied.

The oil-proof film produced by Chuangcheng Technology has been used in waterproof vent caps, waterproof vents, vent gaskets, chemical vent plugs, tissue culture vent caps and other products, and has been recognized by customers.
