Wenzhou Sanhui Machinery Manufacturing Co., Ltd. is one of the leading manufacturers and suppliers of bopp slitting machine in China. With abundant experience, we are able to meet the needs of the majority of our customers. Welcome to wholesale customized bopp slitting machine at competitive price from our factory.
Designed specifically for the characteristics of BOPP film-thin, smooth, and heat-sensitive-this bopp slitting machine eliminates common problems found in standard slitters, including surface scratching, jagged edges, edge curling, uneven tension, and wrinkling. With comprehensive optimization tailored to BOPP production challenges, this bopp slitting machine is perfect for handling large parent rolls. It efficiently performs unwinding, edge guiding, slitting, and finished rewinding all in one seamless operation.
The tension system of the bopp slitting machine adopts magnetic‑powder servo combined constant‑tension control. BOPP film is prone to elongation under tensile force. This machine delivers gentle and controllable tension throughout the whole process. Tension varies adaptively from unwinding and film passing to rewinding, preventing the film from being thinned or stretched. It solves common defects of finished products such as tight inner rolls and loose outer rolls, layer shifting and roll bulging.
Tool configurations can be selected as needed. Straight‑blade cutting is preferred for thin‑gauge BOPP, while rotary‑blade cutting is applicable for thick‑gauge and high‑basis‑weight BOPP. The tool holder features easy adjustment and fast slitting‑width switching. It delivers smooth cutting edges free of burrs and stringing, without generating film edge scraps. All rollers along the film‑travel path are polished to reduce scratches on the film surface and preserve the glossy finish of BOPP.
An optional static‑elimination device is available for upgrade. Static electricity is easily generated when BOPP film runs at high speed. Installing a static eliminator can reduce issues such as dust adhesion caused by static electricity and film material sticking. An automatic unloading mechanism is also optional to lower the labor intensity of manual roll‑removal. Applicable materials: Ordinary BOPP glossy film, BOPP heat‑sealable film, BOPP matte film, and post‑printing BOPP film. It is also compatible with films with similar properties such as PET and CPP.
Support customers to send BOPP sample films for on‑machine trial cutting. Adjust tension, speed and cutting tools according to the customer's film thickness, verify the slitting finished‑product effect, and then finalize the equipment configuration.
