Application of BOPP Tape Slitter Rewinder Machines

BOPP packing tape, also known as biaxial oriented polypropylene film, after high-voltage corona treatment and then coated with acrylic pressure-sensitive adhesive on a rough surface. It has many properties of strong tensile resistance, light weight, low cost, etc, can be customized with different colors and graphic effects according to users’ needs, widely used in various applications such as packaging, bonding, and fixing. In recent years, with the rapid development of e-commerce express delivery industry, the requirement for BOPP tapes in packaging industry has been continuously increasing. As a professional tape production equipment, BOPP tape slitting machine is used to split wide tape rolls into different sizes of finished tape with narrow widths, greatly improve tape manufacturing efficiency and tape quality, meet the market demand for high-quality BOPP packing tapes.

Types of BOPP slitter rewinders

Small dual-shaft tape slitter rewinders are generally used for cutting BOPP tape mother rolls whose width and diameter are both within 500mm. It’s wound simultaneously by two 3-inch slip shafts, and use a razor blade slitting mechanism for cutting work. Realize tension control through PLC calculation to maintain a constant winding tension. The cutting width can be adjusted according to needs by changing the size of the gasket. It has advantages of small volume, convenient operation and low cost, very suitable for small-batch tape cutting applications.

Double or four shaft BOPP tape slitting machinery is generally used to slit BOPP tapes with a width of more than one meter. The operation of touch screen is simple and intuitive, PLC system is used for centralized control. It hasfunctions of meter counting, length setting, web guide and tension control. The four-shaft adhesive tape cutting machine can also complete the exchange of winding shafts to improve cutting efficiency. This type of adhesive tape slitter rewinder can be equipped with sound insulation covers, loading mechanisms, automatic labeling devices according to needs. In practical work, it’s generally used in conjunction with core loading machine, core cutting machine and small rewinding machine.

The fully automatic packing tape slitting machine completely realizes the automation of all processes including paper core loading, mother roll loading, fixed-length winding, shaft exchanging, labeling, tape cut-off, tape connecting, finished roll uploading, manipulator handling. The only thing operator needs to do is to input the corresponding parameters based on material properties, then complete the high-efficiency and high-quality cutting process with just one click. No need to do anything except load the master roll and collect waste edges periodically, greatly reducing the labor intensity of workers. Besides, it ensures the stability of the whole production process, the consistency of product quality won’t be affected by operator’s proficiency, very proper for large-scale, high-precision bopp tape cutting applications.

Development of BOPP tape cutting machines

The production volume of packing tape slitter rewinders has tight relation with demand for BOPP tapes. The economic development in East and South China is very fast, is also the region with the most tape production and use. As time goes on, the potential of consumer market in other regions will be gradually explored. With the optimizing and upgrading of consumption structure, packing adhesive tapes are developing in the direction of functionalization and high-technology. The slitting equipment has experienced the transition from low speed to high speed, from narrow width to wide width, from manual winding to full-automatic winding, from low-precision control to high-precision control. Especially for packing pressure-sensitive tape, the tension of the winding must be moderate, neither loose nor tight. If it is too loose, wrinkles and unevenness may occur, and if it is too tight, it may cause stretching deformation or even damage, ensure the bopp adhesive tape can be easily torn off. After more than 40 years of renovation, accumulation and continuous innovation, the added value and competitiveness of equipment have been continuously improved. Domestic bopp tape cutting machine manufacturers have become quite mature in management, production, technology, inspection, etc, and can basically replace imported BOPP tape slitting machine.
