PP is a raw material for a polypropylene transparent tape substrate, and O is a directionally stretched polypropylene. O mainly refers to the transparent tape with high tear strength in the production process of transparent tape. In fact, the transparent sealing adhesive is basically OPP tape . Let's take a look at the difference between OPP tape and BOPP tape, as follows:
Analysis of the difference between OPP tape and BOPP tape
Analysis of the difference between OPP tape and BOPP tape
1. OPP is a uniaxially stretched polypropylene, and the English full name is Oriented Polypropylene. OPP tape: Scotch tape based on polypropylene film, with high tensile strength, light weight, non-toxic and tasteless, environmentally friendly, its performance is good, and its use range is also very wide.
2, BOPP is biaxially oriented polypropylene, the English full name is Biaxial Oriented Polypropylene, that is, the double-line stretching in the longitudinal and transverse directions, so that its performance is greatly improved. Its characteristics: thin thickness, transparent appearance, non-toxic, odorless, good safety, easy to use, high efficiency, high anti-buffering strength, good retraction rate.
