Sealing tape is also called BOPP adhesive tape, packaging tape, etc. It uses the BOPP biaxially oriented polypropylene film as the base material, which is evenly coated with pressure-sensitive adhesive emulsion through heating, so that it forms a glue layer of 8μM -28μM. It is an indispensable thing in light industrial enterprises, companies and personal life.
This is one of the biggest characteristics of winding film packaging. With the help of the super winding force and retraction of the film, the product is compactly and fixedly bound into a unit, so that the scattered small parts become a whole. Even in an adverse environment, the product does not have any looseness and separation. Bopp adhesive tape jumbo roll has no sharp edge and viscosity, so damage is avoided.
Primary protection provides the surface protection of the super sticky waterproof tape, forming a very light and protective appearance around the product, so as to achieve the purpose of dustproof, oilproof, dampproof, waterproof and burglarproof characteristics. It is particularly important to wrap the packaging tape around the film packaging, so that the packaged items can be stressed evenly and avoid damage to the items caused by uneven stress. This is impossible for traditional packaging methods such as binding, packaging and tape.
With the help of the retracting force of the winding film after stretching, the products are wrapped by winding to form a compact and space-free whole unit, so that the pallets of the products are tightly wrapped together. The adhesive packaging tape can effectively prevent the mutual dislocation and movement of products in the process of transportation, and the adjustable tensile force can make the hard products close together and tighten the soft products, especially in the tobacco industry and textile industry, it has a unique packaging effect.
The use of winding film for product packaging can effectively reduce the use cost. The winding film used for BOPP adhesive tape is only about 15% of the original box packaging, about 35% of the heat shrinkable film and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers and improve the packaging efficiency and packaging grade.
