Advantages and Features of Transparent Vacuum Packaging Bags Transparent vacuum packaging bags are a kind of plastic flexible packaging with high strength. The co-extruded film has the characteristics of stretching during the processing process. After the plastic is stretched, the strength can be increased accordingly. It is also possible to add plastic materials such as nylon and metallocene polyethylene in the middle to make it have a composite strength that exceeds that of ordinary plastic packaging. Delamination and peeling phenomenon, good flexibility, excellent heat sealing performance. This is also one of its advantages. The structure design of the transparent vacuum packaging bag is also very flexible, and different structural designs can be used to meet your different product space and sensory needs. General bag types are: three-side seal, back seal bag, brick bag, side seal bag, etc. The biggest advantage of transparent vacuum packaging bags is the cost advantage. Compared with glass packaging, aluminum foil packaging and other plastic packaging, transparent vacuum packaging bags have a greater cost advantage to achieve the same barrier effect. Due to the simple process, the cost of the film products produced can be reduced by 10-20% compared with dry composite films and other composite films. Because of its advantages and functions that cannot be underestimated, transparent vacuum bags are widely used in various industries, such as Roast duck, roast chicken, beef, salted duck eggs, rice, millet, mung beans, walnuts, preserved fruits and other foods all need this kind of transparent vacuum bag to pack. It uses different plastic materials with different barrier properties, and co-extrudes the film to achieve high barrier effect on oxygen, water, carbon dioxide, odor, etc. Usually referred to as decompression packaging, it is carried out according to the principle of atmospheric pressure, and the main function of the transparent vacuum bag is to deoxygenate, which is beneficial to prevent the food from being moldy and deteriorating.
