Paper-plastic compound bag-compound plastic woven bag is made of plastic woven bag (abbreviated as cloth) and composited by casting method (cloth/film composite is two-in-one, cloth/film/paper composite is triple One). They are mainly used for packaging engineering plastics, rubber raw materials, building materials, food, fertilizer, cement and other powdery or granular solid materials and flexible articles.
The performance requirements of this paper-plastic compound bag are particularly important, and the requirements are as follows:
1. Fastness: The tensile and impact strength of the bag can withstand the pressure in gravity, stacking and impact during transportation.
2. Sealing: due to the different packaging materials of paper-plastic composite packaging, each has different sealing requirements. In particular, the sealing performance of powder or toxic materials and materials that are afraid of being contaminated is very strict.
3. Anti-mildew properties: materials that are prone to moisture or mildew have special requirements for the airtightness of packaging materials.
4. Environmental protection requirements: The packaging bag must be degradable and recyclable materials to alleviate environmental pollution.
5,.Assembly and disassembly performance: modern large-scale industrial production will inevitably require high efficiency, large bag packaging is mostly raw materials or primary processing products, so paper-plastic composite packaging bags also need to meet the requirements of easy to open, easy to dump.
