In retail outlets, especially supermarkets, convenience stores, and chain pharmacies, hanging hole bags have become the preferred packaging solution for small items due to their convenient hanging display function and excellent physical properties.
Packing list envelope bags are not only transparent and tear-resistant, but also available in back-opening and side-sealing versions to meet the needs of different scenarios.
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.
