The Characteristics And Advantages Of Self-sealing Bags

1. High barrier: Self-sealing bags are mainly co-extruded films with high barrier properties of different packaging materials, thereby achieving high barrier effects on oxygen, carbon dioxide, water, odor, etc. Bone-on ziplock bags are the most common in life. How to use bone-on ziplock bags to keep frozen food fresh? 2. Stable performance: moisture resistance, oil resistance, low temperature freezing resistance, freshness preservation, quality preservation and odor preservation, can be used for vacuum packaging, aseptic packaging, and inflatable packaging. 3. Low cost: Compared with glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect of waterproof ziplock bags, its co-extruded film has a greater cost advantage. Due to its simple process, the cost of the film product produced can be reduced by 10-20% compared to dry lamination films and other lamination films. 4. Flexible specifications: you can choose any different ones to meet your different needs for different ziplock bag products. 5. High strength: The co-extruded film has the characteristics of stretching during the processing process, and the strength of the plastic can be increased correspondingly after stretching. At the same time, packaging materials such as nylon and polyethylene can also be added in the middle, so that it can have It exceeds the composite strength of ordinary plastic packaging, and there is no phenomenon of delamination and peeling, the flexibility is very good, and the heat sealing performance is also very good. 6. Small volume ratio: Ziplock bags can be shrink-wrapped in vacuum, and the volume-to-volume ratio is nearly 100%. This packaging effect is unmatched by glass, iron cans, and paper packaging.
