Roll Film is not a finished packaging bag, but a continuous composite film roll that has not been cut into bags. The center is equipped with a standard paper core (usually 3 inches inner diameter), and the material is based on PET, PE, CPP, BOPP, aluminum foil, PA, EVOH, etc. Through the combination of double-layer/three-layer/multi-layer co extrusion composite, dry composite, extrusion composite and other processes, it accurately achieves different barrier, strength, temperature resistance, and preservation functions.
Precision process standards: using high-speed gravure printing, corona treatment, and solvent-free composite technology, with a printing accuracy of ± 0.1mm, high color reproduction, no smudging, and no odor; The slitting end face is flat and free of burrs, and the winding tightness is uniform. It is suitable for high-speed packaging machines with a capacity of 120-300 packages per minute, and can prevent problems such as film sticking, deviation, and breakage.
Basic specification parameters: width can be customized from 50mm to 1200mm, thickness from 30 μ m to 180 μ m, roll diameter from 200mm to 600mm, and each roll length from 500mm to 3000m; Support online molding of various bag types such as back sealed bags, three sided sealed bags, four sided sealed bags, self-supporting bags, and shaped bags, to meet the needs of different packaging machines and product specifications.
