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. Ingredients must be very stable, most standardized raw glass production enterprises in developed countries used refined by specialized producers of raw materials. Ensure Melting furnace thermal parameters for a digital control system for optimal control of the whole process. Severe competitive situation improve production concentration in order to adapt the glass packaging industry faces other challenges caused by new packaging products, a large number of glass packaging manufacturer to begin merger and reorganization, increase the concentration of the glass container industry in order to optimize the allocation of resources, improve economies of scale, reduce disorderly competition, and enhance development capability, which has become the trend of the current world of glass packaging industry.
