OPP TapeAnalysis of the difference betweenand 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.
The choice of packaging material inevitably influences its cost, durability, effectiveness and lead times. This is true across all industries, including bulk bags. Modern bulk bags have been engineered thoroughly and stood the rigours of various tests to prove that they are a great solution for storing and transporting large quantities of material.
However, there are three types of bulk bags that have different properties as a result of their fabric. All are made from polypropylene (PP), which is a strong and durable polymer. Knowing which PP fabric to choose can make a massive difference to the value that you get out of your packaging products.
Custom Bulk Bags is a leading manufacturer and supplier of high-quality bulk bags in South Africa. We produce up to 3.5 million bulk bags per year for various customers. All of our bulk bags have a minimum safety factor rating of 5:1 and are manufactured in accordance with international regulations and standards.
PP is simply the acronym for polypropylene. This plastic has many beneficial properties that make it perfectly suited to packaging and protective coatings. It is often extruded into tapes and woven to create the fabric that is used to manufacture bulk bags. However, PP can be further manipulated.
Hualei are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Orientated polypropylene (OPP) is a type of plastic film that is stretched in one direction, hence the microscopic fibres are aligned. This helps with strength and creates a clear plastic film. OPP is commonly used to manufacture small plastic bags, clear labels and flip files.
Biaxially orientated polypropylene (BOPP) is a plastic that is stretched in two perpendicular directions. This further improves the strength of the plastic and is highly suited to printing, which is why BOPP is often used as a clear coating or laminate over woven PP tapes used for bulk bags. BOPP is ideal for brands that need intricate printing and details on their bulk bags, such as barcodes and small labels.

PP, OPP and BOPP are suited to specific applications. Your packaging company will be able to guide you towards the best product for your needs, but let’s cover some basics. PP bulk bags are your standard packaging product. They can also make good sandbags and geotextiles (or eco-bricks) due to their versatility, durability and cost-effective price point.
OPP is better suited to small packaging materials in the medical, pharmaceutical and food sectors. These packaging products don’t need to carry much weight, but they still need to be protective and durable. Think of sealable sandwich bags or packets for pills.
BOPP is best suited for heavier materials, such as dog food, charcoal or wood. However, when it comes to bulk bags, BOPP can be used as a laminate over the PP fabric to improve the durability of the packaging and the precision of printing.
Custom Bulk Bags manufactures an array of bulk bags that are suited to your needs. These are all based on PP fabric that is extruded and woven in-house. We offer several optional extras, including printing and customisation. For more information about our bulk bags, please contact us today.
