The so-called composite bag can be simply understood as two or more materials that are glued together by glue.
1. The composite bag has the advantage of high strength: due to the multi-layer material, the product has strong resistance to puncture and tearing
2. The composite bag can be resistant to cold and high temperature: it can be sterilized at high temperature and refrigerated at low temperature.
3. Beautiful appearance: it can better reflect the value of the product
4. Good insulation performance, strong protection performance, airtight and moisture-proof, not easy to be attacked by bacteria and insects, good shape stability, and not affected by changes in humidity.
5. The composite bag has stable chemical properties, strong acid and alkali resistance, can be stored for a long time, has strong tear resistance, and has a good packaging effect. The packaged items are not limited by shape and state, and can be filled with solids and liquids.
Sixth, the processing cost of composite bags is low, the technical requirements are low, and mass production can be carried out; and the composite bags are easy to shape, and the production materials are abundant and cheap.
Seven, the composite bag has high transparency, and the object to be packaged can be seen with the composite bag packaging, and the composite bag has good insulation.
8. The composite bag has high strength, good ductility, light weight and strong impact resistance.
