The self-sealing bag is a kind of pressing bag that can be repeatedly sealed. It is also known as dense bag, bone pasted bag, sealed bag, zipper bag. It is an environmentally friendly product, tough and durable, reusable, can be printed on the surface of advertising, shipping marks, can be used as refrigerator storage bag, long service life. Many clothing and food brands have the use of zipper bags to package products, which can prevent things from falling, play an inductive role, and give consumers a neat and standardized image, which is welcomed by consumers. But also can be reused, gently press the ziplink bag will be sealed tightly, non-toxic and tasteless, good flexibility, sealing at will, very convenient. The following professional flexible packaging manufacturer the Guangdong Shunfa Color Printing Co., Ltd. to talk about the advantages and characteristics of self-sealing bags.
1, High Barrier: The self-sealing bag is mainly the use of different packaging materials high barrier performance co-extruded film, and then achieve the effect of oxygen, carbon dioxide, water, smell and other high barrier.
2, Stable Performance: moisture resistance, oil resistance, low temperature freezing resistance, preservation, quality, odor protection, can be used for vacuum packaging, sterile packaging, inflatable packaging.
3, Low Price: compared with glass packaging, aluminum foil packaging and other plastic packaging, waterproof self-sealing bag to achieve the same barrier effect, its co-extruded film has a greater advantage in price. Due to its simple process, the price of the film products produced can be reduced by 10-20% compared with dry composite films and other composite films.
4, Flexible Specifications: can arbitrarily choose different can meet the different needs of different self-sealing bag products.
5, High Strength: the co-extruded film has the characteristics of stretching during the processing, and the plastic stretching can also improve the strength accordingly, but also can add nylon, polyethylene and other packaging materials in the middle, so that it can have more than the composite strength of general plastic packaging, and there is no delamination peeling phenomenon, excellent softness, heat sealing performance is also very good.
6, Small Capacity Ratio: Self-sealing bag can use vacuum shrink packaging, capacity volume ratio is almost 100%, such a packaging effect is glass, tin, paper packaging can not be matched.
