PE Flat Bags

The PE flat edge heavy-duty film packaging bag is a simplified version of the M-fold PE heavy-duty film packaging bag, with the M-fold edge eliminated to ensure uniform strength performance. In practice, many factories are transitioning from woven bags or composite paper bags to PE heavy-duty film packaging bags. However, without access to large-scale, professional sealing equipment, investing heavily in such machinery during the initial stages can be risky. Consequently, most factories opt for simpler sealing devices.

These basic devices are unable to effectively heat-seal the 4-layer folded edge of the original M-fold PE heavy-duty film packaging bags, leading to issues such as package breakage and material leakage. To address this, the PE flat edge heavy-duty film packaging bag has been introduced. This variant is compatible with simple heat-sealing equipment, facilitating a smooth and cost-effective transition.

Moreover, some factories have embraced the single-cut PE heavy-duty film packaging bags. Freed from the constraints of M-shaped folding, these bags offer faster and more convenient sealing, thereby enhancing work efficiency.
