Nowadays, the types and colors of the straps on the market are various, how to distinguish the quality of the straps among the many straps, and the characteristics of the straps. In fact, the quality of the strap is directly proportional to the purity of the polypropylene it contains, so here is how to choose high-quality straps and their corresponding features.
There are many types of strapping on the market: pure polypropylene, polypropylene plus masterbatch, polypropylene plus recycled material, polypropylene plus recycled material and masterbatch. The packing belt produced by pure polypropylene is fully transparent, the packaging of polypropylene and masterbatch is translucent, the packing belt produced by polypropylene plus recycled material is basically opaque, and the packing belt of polypropylene plus masterbatch and recycled material is produced. Completely opaque. There is also a packing belt produced by the whole recycled material and the calcium carbonate powder sandwich material. The packing belt produced by the completely recycled material is relatively soft, and the belt of the sandwich material only has the surface as the raw material, and the rest are the calcium carbonate powder (lime powder). The quality of the strap is completely dependent on the purity of the polypropylene. The higher the purity of the polypropylene, the better the tension of the strap.
Packing tape, also known as PET strapping, is a new type of strapping belt that is popular in the world to replace steel belts. The characteristics of strapping are:
1. High strength: PET plastic steel belt has strong tensile strength, close to the same specification steel strip, which is twice the PP belt, and has the ability to resist impact and extend the product to ensure the safety of the product.
2, high toughness: PET strapping has plastic characteristics, with special flexibility, in the transportation process can avoid the breakage of the strap caused by bumps caused by bumps, to ensure the safety of transportation.
3, flexibility: PET belt does not have the sharp edge of the steel belt, will not cause damage to the packaged object. It will not cause damage to the operator when packing and unpacking, and avoid all unsafe factors.
4. Adaptability: The melting point of PET plastic strip is 255°C~260°C, which can maintain the invariance between -110°C~120°C for a long time, and has good dimensional stability. PET belt can be suitable due to material and manufacturing process factors. All kinds of climate change, high temperature and humidity resistance, unlike the steel belt damp and rust pollution environment and loss of tensile strength, the bale strength is reduced.
5. Convenience and environmental protection: Because the PET belt is light in weight and easy to handle; it is small in size and saves warehouse space; the used PET belt is convenient for recycling and meets environmental protection requirements.
6. Economic Benefit: The density of PET plastic strip is 1.30~1.38 g/cm?, which is only 1/6 of the density of steel strip (7.8g/cm?). The price per unit length is relatively low.
7, beautiful, no rust: steel strip will be exposed to the air and absorb the moisture in the air causing rust, PET plastic strip will not.
Plastic steel strapping is widely used in steel, aluminum, chemical fiber, cotton spinning, tobacco, paper, metal cans, etc. due to its low cost, beautiful and durable, environmentally friendly recycling and high degree of automation.
