Advantages and characteristics of transparent vacuum packaging bags for composite packaging bag manufacturersTransparent vacuum packaging bag is a kind of plastic flexible packaging with high strength. Co-extruded film has the characteristics of stretching during processing. After stretching, the strength of the plastic can be increased accordingly. Plastic materials such as nylon and metallocene polyethylene can also be added 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 strengths.The structural design of the transparent vacuum packaging bag is also very flexible. Using different structural designs can meet your needs for different product spaces and sensory requirements. The 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 must achieve the same barrier effect, and co-extruded films have a greater cost advantage. Due to the simple process, the cost of the produced film product can be reduced compared with dry composite film and other composite films10-20%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, walnut kernels, preserved fruits and other foods. This transparent vacuum bag comes for packaging. It is a co-extruded film that uses different plastic materials with different barrier properties to achieve a high barrier effect on oxygen, water, carbon dioxide, and odors. It is usually called decompression packaging, which is carried out according to the principle of atmospheric pressure, and the main function of transparent vacuum bags is to remove oxygen, so as to help prevent food from mildew and deterioration. Not only that, but it is extremely functional: resistant to oil, moisture,120High-temperature cooking in Celsius, resistant to low-temperature freezing, quality preservation, freshness preservation, and odor preservation, can be used for vacuum packaging, aseptic packaging, and air-filled packaging.
