Which is more affordable, PET strapping strap or PP strap?

PET strapping is a very versatile plastic environmental protection strapping. PET strapping has been produced in China for more than 20 years. Since 2002, China’s demand for PET strapping has grown at an annual rate of 500%. It is now widely used in wood, paper, steel, aluminum ingots, steel pipes, profiles, glass, building materials, ceramics, electrical appliances, and metal products. , Tobacco, chemical fiber, cotton and other industries. The appearance is transparent (opaque after adding the adhesion promoter), the surface is flat or has prismatic patterns. The main raw material of PET strapping is polyethylene terephthalate.

PP strapping straps are packaging straps (bundling straps) made of polyethylene, polypropylene resin, cold-rolled strip steel as the main raw materials, and nylon and polyester are also used as raw materials. They are made by extrusion and unidirectional stretching, and are heat-treated. Made blue. In addition to corrugated box sealing and strapping, hot-rolled steel coil strapping, cold-rolled steel coil strapping, it can also strap glass, pipes, materials, fruits, etc.

The two different materials belong to the packaging consumables used in packaging, and they have been popular in China for 20 years. The two kinds of strapping have different characteristics, so they are used in different industries. PET plastic-steel belts are often used to pack heavy goods due to their tensile strength, strong elongation, low elongation, strong temperature resistance, and good safety. However, PP packaging belts have a small specific gravity and low tensile strength. The reason why the number of meters in the weight is longer is often applied to pack lighter goods. Generally, cartons for electronic products are mostly packed.

For these two kinds of packing belts, it is not appropriate to compare the unit price alone to determine which is more affordable, because the goods that can be packed by the two kinds of packing belts are not the same, so when you need to develop a packing plan, you need to consider this kind of packing. Whether the belt is suitable for you, instead of blindly seeking the lowest price.
