Sealing machine according to the unique properties of aluminum with aluminum and other high barrier materials after dry composite into aluminum foil bag products. ,
The main film substrates of the composite bag are: the outer printable film BOPABOPETBOPP the inner heat-sealable film CPPPE and the co-extruded film. Aluminum foil is also one of them, the characteristics and differences of aluminum foil bags and composite bags Aluminum foil bags refer to a composite bag containing aluminum foil. Usually as the middle layer of these materials according to the requirements, the plastic drum sealer is combined into a composite film by glue.
Aluminum foil bag rare structure: PET/PA/PE or CPPPET/AL/CPPPA/AL/CPPPET/PAO/AL/CPP basic characteristics are: the PE is suitable for the use of low temperature, CPP is suitable for high temperature cooking makes PA in order to increase the physical strength, durability performance, AL aluminum foil is to increase the barrier performance, milk tea sealing machine shading is generally used as an intermediate layer PET to increase mechanical strength, crisp. Toy blister sealing machine and then according to demand, combination, various performance, but also transparent in order to increase the barrier resistance of oxygen and moisture can use water resistant PVA high barrier coating 1 aluminum foil bag with metallic luster, filling sealing machine has a high reflection ability to heat and light, vacuum packaging bag and aluminum foil bag printing color is more beautiful and bright.
The aluminum foil bag has good isolation performance, strong maintenance performance, and has the characteristics of imperishable gas and moisture. The blister sealing machine can effectively prevent moisture absorption and gasification of the contents, which is not easy to be damaged by bacteria and insects. The shape stability is good and is not affected by humidity changes. 3 The use of shielding or elute local aluminum plating, can obtain any pattern and any transparent window, aluminum foil sealing machine so that customers can see the packaging contents, which is a major progress in aluminum foil bag production technology, but also a significant feature of aluminum foil bag composite bag and aluminum foil bag, the difference between vacuum bags.
