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.
In the choice of self-adhesive label materials, can often be heard PP, OPP, BOPP of the three, that in the end there is no difference between them? The difference in where? Here by Philip open for you to do a simple analysis:
OPP: oriented polypropylene (BOPP)
PP: Polypropylene
BOPP: Biaxially oriented polypropylene
PP is a semi crystalline thermal plastic plastic, has a high impact resistance and mechanical properties of strength and toughness, various kinds of organic solvent and acid and alkali resistance, in the industrial sector is widely used, is one of the usual common polymer materials. Australian coins also use polypropylene production.
OPP, PE, PET and so on are plastic products, often put BOPP (BOPP) referred to as OPP.
Touch, OPP is more brittle and soft PP will be slightly better.
Opp tape: polypropylene film as base material, and has high tensile strength, strength and elongation lightweight, non-toxic, tasteless, environmental protection, the use of a wide range of advantages OPP bottle: light weight, low cost, improve transparency, heat resistance is good, suitable for used for hot filling. In recent years, two-way polypropylene (OPP) has become a transparent bottle PET bottle PP is selected. Polypropylene, polypropylene as general structure parts, corrosion resistant chemical equipment parts, electric heating insulation. Identification of waste plastics are: plasticizing temperature differential method, combustion method, density identification method, identification method: the melting temperature of the melting temperature of LDPE110~115; HDPE140~145 LLDPE125~130:PP165~170; PS145~150; PVC150~170; combustion characteristics of combustion flame identification method: name degree of appearance smell PE upper yellow, blue bottom; uninterrupted combustion; smokeless, melting such as paraffin drops; the same smell of burning PP PE flame color; ditto black smoke, melt dripping; such as oil smell PS orange flame; ditto thick smoke, softening and foaming; such as styrene taste PVC upper yellow, the bottom green self extinguishing white smoke, soft spinnbarkeit; such as hydrogen chloride pungent flavor, Neihuang PET blue burning uninterrupted split into pieces; pungent appearance characteristic: PE feel is smooth, not colored, translucent, soft Tough. LLDPE feel more soft and hard PP HDPE are slightly harder than the PE, better transparency, no coloring white translucent PVC color is yellowish and transparent, transparent than PE PP. Soft soft and tough products. Hard products hardness is higher than LDPE and lower than PP. PET PET: the bottle bottle material for high temperature crystalline material, the bottle and the bottle with the same color as the material of low temperature....... Dongguan Jiabao Industry Main: Dongguan PE PET PET lens protective film protective film anti scratch protective film.
