Packaging

High concentration of chemical solvents are corrosive and easy to release gas, so it is necessary to use a breathable but leak-free container packaging such as high barrier breathable gaskets, breathable plugs, breathable caps, etc., to balance the internal and external pressure difference of the container, otherwise the container will be deformed or even leak due to high internal pressure.

Tissue culture refers to the new science and technology of growing, multiplying, differentiating and regenerating plant organs, tissues, cells and protoplasts in vitro on artificial medium. Tissue culture bottle and tissue culture cap are widely used in the culture process of tissue culture seedlings, and the bottle cap plays an important role in isolating the inside and outside environment of the bottle.

In order to meet the needs of different assembly torque and sealing, chemical foam liners, physical foam liners, IXPE high-foam liners, various aluminum foil sealing materials are widely used in various cosmetic packaging materials such as emulsion bottles, cream bottles, vacuum bottles, etc

With the increasingly strong demand for waterproof intelligent electronic devices, the ePTFE waterproof sound transmitter film has been created, which has the functions of sound transmitter and pressure equalizing on the basis of waterproof and dustproof. The waterproof solution represented by "waterproof breathable film" has risen strongly under the general trend of "waterproof", "dustproof" and "breathable" of smart electronics, and has realized the application on terminal products such as smart phones, smart watches, and TWS headphones.

Food sealing materials are materials used to package food and keep it fresh and safe. Common food sealing materials include plastic film, aluminum foil, pressure sensitive gaskets, physical foam gaskets, paper and other composite materials. These materials can be used in sealed bags of food, canned food and other food packaging. Some sealing materials also have moisture-resistant, leak-proof, breathable and antioxidant properties to ensure food quality and safety.
