In modern packaging product manufacturing, PE (polyethylene) zippers have become key auxiliary materials in multiple fields such as food, medicine, daily chemicals, and electronics due to their lightweight, waterproof, moisture-proof, and corrosion-resistant properties. High-quality PE zippers not only enhance the functionality and aesthetics of packaging but also ensure product safety, extend shelf life, and optimize user experience. The importance of their quality is mainly reflected in the following aspects:
1. Sealing performance determines product freshness and safety
In the field of food packaging, the sealing performance of PE zippers directly affects the preservation effect. High-quality PE zippers can effectively block oxygen and water vapor. For example, the water vapor transmission rate of vacuum preservation bag zippers should be less than 5g/m²·24h; otherwise, it may lead to food oxidation and deterioration. In medical packaging, medical-grade PE zippers must meet the ISO 11607 sealing standard to ensure a sterile environment. Inferior zippers may cause medicines to become damp or contaminated, posing safety risks.
2. Durability affects packaging reliability and cost
High-quality PE zippers can be opened and closed over 5,000 times (ASTM D2061 standard), while inferior zippers may break or have teeth slip after several hundred uses, leading to packaging failure. For instance, in e-commerce logistics, if low-quality zippers are used in frequently opened and closed packaging bags, the damage rate can be as high as 5%, increasing return and after-sales costs. In contrast, high-strength PE zippers can withstand compression and friction during transportation, reducing the damage rate to below 0.3%, which is more economical in the long run.
3. Environmental performance aligns with sustainable development trends
With increasingly strict global environmental regulations, the sustainability of PE zippers has become an important consideration. High-quality PE zippers use recyclable materials or bio-based PE, such as PLA composite zippers that can degrade by over 90% within six months. Inferior zippers may contain harmful additives and fail to meet EU REACH or US FDA standards, affecting product exports and market competitiveness.
4. Special functions expand packaging application scenarios
In fields such as electronic anti-static packaging and heavy industrial packaging, PE zippers need to have anti-static and high tensile strength (above 20kg/cm) properties. For example, carbon fiber reinforced PE zippers can prevent static damage to electronic components, a requirement that ordinary zippers cannot meet. Additionally, smart zippers (such as those integrated with NFC chips) can achieve anti-counterfeiting and traceability, enhancing brand value.
The quality of PE zippers directly affects the performance, safety, and cost-effectiveness of packaging. Although high-quality zippers have a higher initial purchase cost, they can significantly reduce damage rates, extend product shelf life, and enhance brand image. In the future, with the development of smart packaging and green materials, high-performance PE zippers will become an important competitive factor in the packaging industry.
