In modern logistics systems, a package often undergoes sorting, stacking, long-distance transportation, multiple loading and unloading operations, and even rough handling, from its origin to its recipient.
The durability of the sealing strip was evaluated by simulating extreme conditions such as repeated opening and closing, high temperature and humidity, and low temperature freezing.
Multi-layer co-extruded self-adhesive bags align with sustainable development trends by reducing material usage and waste generation.
For low-temperature environments, adding cold-resistant plasticizers or using special grades of PE resin can prevent the material from becoming brittle at low temperatures.
In the printing process of self-adhesive bags, the adhesive layer is the core component for achieving the sealing function, and its integrity directly affects the product's sealing performance and user experience.
PE logistics delivery bags, with their unique low-temperature toughness, have become the core packaging material to ensure the safety of goods in cold chain transportation.
