Why composite paper cans can achieve excellent sealing? This depends on the composite paper can made of paper and aluminum foil, which has good sealing performance and has the functions of waterproof and moisture-proof, so it can better ensure the safety of food and greatly improve the shelf life of food.
Besides, our high-barrier LS film can replace aluminum foil to achieve compostable and environmentally friendly purposes. As a sustainable company, our composite paper cans are made up of all paper. Especially for the bottom sealing, the whole paper material replaces most of the metal material sealing on the market. We are realizing the technology of all-paper airtight cans.
