Author:composite film packaging customized    Time:14/10/20    Click:
Because a lot of base material composite film bag, the test standard is basically to smooth appearance, no scratches, burns, bubbles, and oil, and wrinkle, heat sealing level off, without a virtual closure.Film can not have crack, pore and composite layer separation.Without impurities, foreign bodies, and oil and pollution.Because it is used for packing food, at the same time have requirements to the smell of the bag, can not have peculiar smell, odor, turbidity and decoloring phenomenon.
In terms of physical and mechanical properties, the performance of the composite film bag generally higher than that of monolayer film bag.In such aspects as the tensile strength, elongation at break, tensile ability is stronger, the compound thin film composite membrane bag made of food packing bag can better prevent in use process, the phenomenon of the broken and damaged.
Composite film bags and barrier property, oil resistant, heat resistant, cold resistant, resistance to medium such as index, the sealing of bag bag body of stripping force, pressure and resistance to fall with related indicators.
Is mainly detected composite film bag of safety and health for evaporation residue, potassium permanganate consumption, heavy metals, decolorizing test, etc.
