The ‘composite film bags’ represents one of Bofeng New Materials' core achievements in packaging materials science, embodying the pinnacle of high-performance and customized packaging solutions. This product series is not composed of a single material. Instead, through innovative processes such as co-extrusion, dry lamination, and film coating, two or more distinct film materials (such as PE, PP, PET, PA, EVOH, aluminum foil, etc.) are precisely combined to achieve ‘1+1>2’ exceptional performance. We focus on imparting comprehensive advantages to film bags through precise interlayer structure design and material selection. These include barrier properties (moisture vapor, oxygen), mechanical strength (tensile resistance, puncture resistance), weather resistance (extreme temperatures, UV exposure), and specialized functions (antistatic, anti-fog). Our aim is to provide comprehensive solutions—from fundamental to cutting-edge—for industries with stringent packaging protection requirements.
- Multi-layer Composite Bags: Spanning from fundamental 2-layer and 3-layer co-extruded structures to 5-layer and 7-layer high-barrier composites with exceptional oxygen and moisture resistance, meeting varying levels of shelf-life and safety requirements for food, pharmaceutical, and electronic products.
- Functional Composite Bags: Offer anti-static bags protecting delicate electronic components, anti-fog bags maintaining clear visibility of contents, UV-resistant bags preventing product degradation, and high-transparency composite bags for optimal display effects.
- Specialized Composite Bags: Developed for extreme environments, these include high-temperature resistant bags withstanding steam cooking or sterilization, low-temperature resistant bags maintaining flexibility without cracking in freezing conditions, and puncture-resistant high-strength bags for packaging sharp items.
