Sealing tape is also called bopp scotch tape, packing tape, etc. It is based on BOPP biaxially oriented polypropylene film, evenly coated with pressure-sensitive latex to form an 8----28-inch rubber layer. It is an indispensable item in light industrial enterprises, companies and personal life.

The country does not yet have a sound industry standard. only one industry standard“QB/T2422-1998 BOPP sealing with pressure-sensitive tape”The surface will be rough through the high-voltage corona treatment of the original BOPP film. Glue is applied to the top, first form a master roll, and then cut into small rolls of different specifications by a slitting machine, this is the adhesive tape we use every day. Pressure-sensitive adhesive emulsion, the main component is butyl ester.





Unitization: This is one of the biggest features of packaging film packaging. Due to the superior winding force and shrinkage performance of the film, the product is compact and fixedly bundled into a whole, so that the scattered small pieces become a whole, and the product will not loosen or separate under unfavorable environments, and there is no sharpness. Edged and sticky to avoid damage.


Primary protection: Primary protection provides surface protection for the product, forming a very light protective appearance around the product to achieve dust, oil, moisture, water and safety. It is especially important that film packaging enables the packaged items to be compressed evenly and avoids damage caused by uneven forces. This is not the case with traditional packaging methods (bundling, wrapping, tape, etc.).


Compression fixation: The product is wrapped and wrapped by the retractive force of the stretch film to form a compact, space-saving unit, so that the pallets of the product are tightly wrapped together, effectively preventing the product from being in transit. Mutual misalignment and movement, while adjustable tension can bring hard products close to each other and soft products close together, especially in the tobacco and textile industries

Cost saving: The use of packaging film can effectively reduce product packaging. The stretch film is only about 15% of the original box packaging°, about 35 of the heat-shrinkable film°, about 50 in carton°. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grade
