Main production process:
Melting of plastic pellets---pressing---forming---cooling---winding---packing---warehousing
PET plastic-steel strapping is a packaging material with a mesh structure produced by heating, melting, stretching and cooling polypropylene. The basic parameters that affect the strapping quality are tension, length, bending, elongation, etc. In the same pressure and other parameters, the longer the size, the lower the cost.
So what are the advantages of plastic steel packaging?
①High strength: PET plastic steel belt has muscular tensile strength, which is close to the steel belt of the exact specification, twice that of PP belt, and has the flexibility to resist impact, which can ensure the product's safety.
②High toughness: PET packing belt has plastic characteristics and exceptional flexibility, which can avoid scattering objects due to the break of the packing belt caused by bumps during transportation and ensure the vehicle's safety.
③Flexibility: PET tape does not have the sharp edges of steel tape and will not cause damage to the packaged objects. When packing and unpacking, it will not cause harm to operators and avoid all unsafe factors.
④Adaptability: The melting point of the PET plastic steel strip is 255℃~260℃, and it can remain unchanged between -110℃~120℃ for a long time and has good dimensional stability. Due to the material and production process factors, the PET belt can be suitable for various climate changes, resistant to high temperature and humidity, unlike steel belts damp and rusted to pollute the environment and lose tensile strength, which reduces the power of the bale.
⑤Convenience and environmental protection: Because the PET tape is light in weight, it is convenient to carry; its small size saves warehouse space; the used PET tape is easy to recycle and meets environmental protection requirements.
⑥Economic benefits: The density of PET plastic steel belt is 1.30~1.38 g/cm³, which is only 1/6 of the steel belt thickness (7.8g/cm³), and the price per unit length is relatively low.
⑦Beautiful and non-rusting: the steel belt will absorb the moisture in the air and cause rust when exposed to the air, but the PET plastic steel belt will not.
⑧ Withstand tremendous pressure and strong pulling force.
Packing straps (bundling straps) are made of polythene and polypropylene resin as the primary raw materials, and nylon and polyester are also used as raw materials. They are made by unidirectional stretching by extrusion. Plastic strapping has good elastic recovery, high strength, good water resistance, strong chemical resistance, light and soft, and can be packaged by hand or machine. It is easy to use and can be made low cost into red, white, blue, yellow, green, etc. Different goods can pack according to the colour, convenient for distinguishing the goods' status to improve delivery efficiency. In addition to sealing and packing corrugated boxes, it can also pack materials and fruits. Polyester and nylon straps have good tensile strength, while polythene and polypropylene straps have low cost, and polypropylene has good resilience. Different materials can be used according to needs.
1. The PP material produced can be divided into a core-spun packing belt and solid-core packing belt;
2. According to the machine used, it can be divided into manual packing belt and machine packing belt (also divided into automatic packing belt and semi-automatic packing belt);
3. From the scope of use, it can be divided into packaging straps (packing straps) and crafts straps;
4. There are other packing belts with printing and non-printing, etc.
PET strapping: alias plastic steel strapping, referred to as plastic steel strap. It is a product that gradually replaces iron strapping. The main component of the PET is a polyester resin. The production process can also be divided into an embossed plastic steel belt and a smooth plastic steel belt.
