What is a composite bag

                                              What is a composite bag

Composite bag refers to two or more materials that are bonded together using machine glue. Suitable for vacuum packaging or general packaging of food, electronic products, chemicals, pharmaceuticals, tea, precision instruments, and cutting-edge national defense products.

The advantages of composite bags are:

1. The firmness of composite bags. Composite bags are made of multiple layers of materials bonded together, with high strength. Therefore, the product has excellent tear resistance, puncture resistance, tensile resistance, impact resistance, good extensibility, good insulation performance, and strong protective performance. And the composite bag is cold resistant and high-temperature resistant, which can achieve high-temperature disinfection and low-temperature refrigeration together with the product. Because the composite bag is opaque, the paper in the inner layer of the bag can avoid ultraviolet radiation, and it is not easy to age after long-term use, playing a certain anti-aging role. 

2. Waterproof properties of composite bags. Composite bags are not breathable, not easily affected by bacteria and pests, and not affected by humidity changes. They have good shape stability and can effectively prevent water, moisture, and mold, providing better protection for products. Some special materials also have special requirements for airtightness. 

3. The environmental friendliness of composite bags. The inner and outer layers of the composite bag can be recycled after soaking, and it is a biodegradable and recyclable material that can be processed in a way that leaves no residue. Its service life is longer than that of ordinary paper bags, which can reduce waste, save resources, and alleviate environmental pollution.

 4. The aesthetics of composite bags. Composite bags can be printed and customized in multiple colors, with different effects made according to different needs. At the same time, composite bags have different production processes and material classifications, which can achieve beautiful appearance while meeting needs, and better reflect the value of the product.

5. Chemical stability of composite bags. Composite bags have stable chemical properties, strong acid and alkali resistance, and can be stored for a long time. At the same time, the packaging effect is good, and the packaged goods are not limited by form or state. Both solid and liquid can be packed.
