Machine-grade stretch films are primarily classified based on raw material quality, stretchability, thickness specifications, usage environment, and packaging requirements. Different grades vary in terms of strength, ductility, self-adhesion, and scope of application; users can select the appropriate grade based on the characteristics of the goods and the requirements of their packaging equipment.
Standard-Grade Machine Stretch Film
Primarily used for the routine packaging of general cargo, this film is produced from conventional polyethylene materials and offers basic stretchability, transparency, and load-securing capabilities. It is suitable for lighter loads and shorter transport distances-such as cartons and pallets-offering cost-effectiveness and ease of use.
Reinforced-Grade Machine Stretch Film
This grade improves upon the standard version by enhancing material formulations and production processes to increase film strength and toughness, thereby offering superior tear and puncture resistance. It is suitable for heavier loads, complex shapes, or challenging transport environments, providing greater load stability and reducing the risk of film breakage during the packaging process.
High-Performance Machine Stretch Film
Typically produced using multi-layer co-extrusion technology, this film features an optimized layer structure that combines high stretch ratios, high elastic recovery, and excellent self-adhesion. Designed for high-speed automated packaging equipment, large logistics centers, and industries requiring superior load stability, it delivers excellent protection while reducing material consumption.
Functional Machine Stretch Film
This category incorporates special features beyond basic performance characteristics, such as anti-static properties, UV resistance, high transparency, color coding, or low-temperature resistance. These films are primarily used in sectors with specific packaging requirements, such as electronics, specialized industrial goods, and export shipping.
