Most dairy products need to be stored and transported under sealed and refrigerated conditions, to ensure the flavor and taste of dairy products, We generally use aluminum foil as the sealing material for our dairy products to block air, while the sealing layer is made of heat-sealable materials selected according to the properties of different materials.

For the sealing of plastic cup products, since there is no protection from a lid, the edges of the seal are usually wider and the material is thicker. Sometimes, embossed patterns are pressed onto the aluminum foil to increase the material’s thickness, ensuring a good contact surface during sealing.

Moreover, to make it easier for users to peel off, the sealing layer of dairy products uses easy-to-peel heat-sealable materials.
