Large three-dimensional aluminum foil bags - plastic film vacuum bags plastic composite film composite membrane types of plastic into plastic film and aluminum composite membrane two kinds. Plastic film structures 1, PET / aluminum CPP (lightweight product structure) 2, PET / AL / PE (10KG below with structure) 3, PET / AL / CPP (use of pesticides structure) 4, PET / AL / NY / PE (re-use of packaging structure) product thickness can recommend or light products according to customer requirements thickness recommend sided 4-sided silk pesticide products recommend a thickness of 10 silk repackaged product recommendations based on product features single wire thickness of 12 to 15 wire Product specification roll film width: 1000mm ~ 1500mm. 1000 m length is generally triangular envelope bags: width 50mm ~ 1000mm length 2.5 Mira chain bag: Width 50mm ~ 1200mm height: 1 meter Features flexibility, moisture and oxygen barrier, shading, shielding, antistatic, can be evacuated, You can color printing. Each used a different material structure, leading to the final performance is not the same. Indicators 10 times or even a hundred times may vary. Scope can be used for food, medicine, pesticide, chemical, mechanical and electrical products. Vacuum bags and bags of ordinary by comparison, has a relatively superior performance, both to extend the shelf life of goods, but also to ensure its flavor intact. This is because the bag has a special functionality. The vacuum bag must have a very good sealing properties, namely air and moisture barrier properties, the barrier of the ingredients are water, oxygen and carbon dioxide, so that goods in a completely isolated environment protected, this high barrier made of co-extruded film, a relatively stable nature
