About PET plastic strapping

January 07, 2019



  PET History: First in 1941 by the British J. Tt . Whinfield and J. T. Dickon was successfully developed. PET has been a fiber raw material for 53 years. British Imperial Chemical Company (1.c. I) was put into production in 1946 with Teleron fiber, and then Dupent in the United States in 1948. (Dacron) Fiber is put into production. PET Classification and Use: PET The main raw materials, p-xylene and terephthalic acid (PTA), are widely used as fibers and can be divided into non-engineering plastic grades and engineering plastics grades. PET has excellent properties (heat resistance, chemical resistance, toughness, electrical insulation, safety, etc.) and is inexpensive, so it is widely used as fiber, film, engineering plastics, polyester bottles, etc.

The PET straps are made of POLYESTER (PET) material, commonly known as plastic straps. Polyethylene terephthalate is therefore a finishing material for strained materials. It is a new type of steel used in place of steel. Environmentally-friendly packaging materials have been used extensively in the non-ferrous metals, steel industry, chemical fiber industry, aluminum ingot industry, paper industry, screw industry, tobacco industry, electronics industry, textiles after the successful opening of new materials and cost reductions in recent years. In addition to the advantages of significantly lower packaging costs, PET tapes have the following advantages:
· High strength: PET plastic steel strip has strong tensile strength, close to the same specifications of the steel strip, is twice that of the PP strip, and it is also able to resist the impact of the ductility, and better ensure the quiet of the product.
· High toughness: PET Strapping tape has special plasticity and special flexibility. In the process of transportation, it can restrain the strap from breaking due to the bumps caused by the bumps and ensure the quietness of the transportation.
· Flexibility: PET strips do not have sharp edges on the strip and do not damage the packaged objects. In the package and open package will not cause harm to the operator, restraint is not quiet. 
   Although steel packing tapes are still widely used, they are inconvenient to process because of their high hardness, and are prone to burrs, and the surface roughness is easy to scratch the fingers, and there are many inconveniences for the packaging of goods. The new PET plastic steel strap has a small density and good toughness, and the surface is smooth and not easy to hurt. Because of the small weight and low cost, many packaging industries are now using this product [3]. PET is an ester bond, which is decomposed under the action of strong acid, strong alkali and water vapor. It is resistant to organic solvents and weather resistance but has the disadvantages of low crystallization rate, difficult molding process, high molding temperature, long production cycle and impact. Poor performance material. The main method of PET plastic steel material is film extrusion method, which can be mass-produced according to the grain properties of PET materials, which provides the best support for mass production of PET plastic steel products.

· Economic benefits: The density of PET plastic steel belt is 1.30~1.38 g/cm3, which is only 1/6 of the density of the steel belt (7.8g/cm3), and the cost per unit length is relatively low.
· It is elegant and does not rust: The steel strip will cause rust due to the moisture in the atmosphere exposed to the atmosphere, and PET steel strip will not.
