[Pure plated aluminum foil bags and bags of difference]: First, from the material, said aluminum is aluminum bags, high-purity aluminum bags doped composites. Second, from a cost that is higher than the price of aluminum bags aluminum bags. Third, from the performance that aluminum bags moisture, the cooling effect is better than aluminum bags aluminum bags completely dark, aluminum bags shading effect is four, from the use, the aluminum vacuum bags more suitable for loading Deli , meat, aluminum bags suitable for loading tea, powder, aluminum bags and other electronic components is a soft material, a certain degree of elongation, and aluminum bags are brittle. Water vapor transmission: ≤0.006g / m · 24h (40 ℃ · 90% RH) Oxygen transmission rate: ≤0.024ml / (. M · 24h · 0.1mPa) Composite strength:> 25 N / 15mm Edge Strength:> 35 Newton / 15mm puncture strength:> 24 lbs sealing temperature: 150 ℃ ± 10 ℃ 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.
