Double-layer staggered exhaust PE valve bag is a packaging bag with a special structure, mainly used to improve packaging efficiency and protect the internal items. Its design features include double-layer structure, staggered exhaust and PE material, which work together to enable the valve bag to better protect the contents during transportation and storage.
Structural features
Double-layer structure: The double-layer staggered exhaust PE valve bag consists of an outer bag and an inner bag. The top of the inner bag is fixedly bonded with a double-layer structure valve port. This design can effectively exhaust and improve exhaust efficiency, while preventing external air from entering the bag body and preventing it from slipping during transportation.
Offset exhaust The bag body is equipped with staggered breathable components, which are located between the outer bag and the inner bag to ensure that the gas can be discharged smoothly and the outside air cannot enter the bag body.
Anti-slip array design: The surface of the outer bag is equipped with an anti-slip array, located between the two breathable components, to further prevent the bag body from sliding during transportation.
Materials and manufacturing process
Material: The main material of the double-layer offset exhaust PE valve bag is polyethylene (PE), which is wear-resistant, waterproof, moisture-proof and resistant to heavy pressure, and is suitable for packaging that needs to withstand a certain weight and pressure
