The use of aluminum foil bag and classification

Aluminum foil bag packaging usually refers to lu: su composite vacuum packaging, such products are suitable for the large-scale precision machinery equipment, chemical raw materials, pharmaceutical intermediates, moistureproof, avoid light, vacuum packaging. With four layers structure, has the good water, oxygen insulation function. Can not restricted, quantity body custom make the packing bag of different specifications, style, can be made into flat pocket style, three-dimensional bags, organ bags, etc. Properties of different materials together, to improve the permeability of packaging materials, moisture permeability, oil resistance, water resistance and drug resistance, make it play a insect-resistant, dustproof, microorganisms, light, sweet, smelly odor such as isolation, as well as heat, cold resistant, impact resistance, better mechanical strength and processing performance, and have good printing and decoration effect. People have a lot of understanding of packaging, she is will be classified according to use environment and performance, the use of aluminum foil bag classification: according to the packing in the form of classification: in the three edge sealing, Yin and Yang bag, seal, pillow type bag, five edge-sealing bag, self-reliance bag, zipper bag, straw bags, coil, according to the functions such as cover material classification: Yin membrane bags, cooking bags, antistatic high antibacterial membrane bags, bag, anti-fog film bag, vacuum bag, resistance to chemical film bag, oxygen packaging film bag, packaging film bag of air, as according to the material classification for: laser aluminized film compound paper material, laser transfer paper, paper composite materials, composite materials, aluminum plastic composite material, fabric composites, etc. Aluminum foil bag composite flexible packaging material to be made into all kinds of packaging bags can finally use. Bag there are two ways, one is packing with vendors using film in automatic packaging machine, filling and forming into various packaging bags; Another is due to the bag making mechanism into various bags before loading content. Due to the professional bag control precision, beautiful bag type, change of bag, bag type, therefore, in quite a few cases, is first made into bags. Bags of the main varieties are: 3-side ( Crossing their seal) , back seal bags, folding help ( The organ bag) , vertical bag, etc.
