The Difference Between Opp and Bopp Tapes
May 23,2022
We often come into contact with transparent tapes in our daily life, generally for sealing tape purposes and other life uses. Commonly used transparent tape mainly has OPP tape and BOPP tape, but they have the difference?
The difference between OPP and BOPP tapes
The answer is yes, OPP tape is oriented polypropylene (film), that is, oriented polypropylene, is a kind of polypropylene material. The full English name is: Oriented Polypropylene, is a polypropylene film as the base material of transparent tape, with high tensile strength, light weight, non-toxic, tasteless, environmental protection, the advantages of a wide range of use. The most commonly used tape for sealing boxes for express delivery.
And BOPP tape is biaxially oriented polypropylene (film), is also a kind of polypropylene. The full English name is Bi axial Oriented Polypropylene, through the longitudinal and transversal bilinear stretching, so that its performance is greatly enhanced.
BOPP tape has the advantages of high tensile strength, light weight, low cost, non-toxic and odorless, etc. As a packaging material, it is widely used in sealing and packaging of cardboard boxes, fixing, strapping and sealing of objects.
BOPP tape is the upgraded version of OPP tape, both the scope of application and performance have been greatly improved. bopp tape can be applied to adhesive tape, transparent bags, heat sealing film, pearl film, metalized film, food packaging bags, etc.
CPP cooking bag is also a polypropylene material: cast polypropylene film, and the previous two are not related, the molecular structure is different, the nature is not the same. CPP cooking bag can be divided into ordinary cooking bag, high-temperature cooking bag, high-temperature toughness cooking bag. In addition to ensuring that sealed food can be well heated, but also to ensure that food ingredients do not penetrate and do not leak. And steaming bags must pass ROHS certification, can contact the food, harmless to humans.
The usual impression is that polypropylene material can only make rigid products, but in fact, it is not. Different molecular structures of polypropylene are used for different purposes, from garbage cans to toy cars and films, polypropylene has a wide range of uses.
