Packing material package with details
Packing straps (bundling tapes) are mainly made of polyethylene and polypropylene resins. Nylon and polyester are also used as raw materials. They are produced by uniaxial extrusion. The elasticity of the plastic packing belt is good, the strength is high, the water resistance is good, the chemical resistance is strong, light and soft, and it can be packaged by hand or machine. Easy to use, low cost, can be made of red, white, blue, yellow, green and other colors, according to color package different grades of goods, easy to distinguish the level of goods, improve delivery efficiency. In addition to packing and packing for corrugated boxes, materials and fruits can also be packaged. The tensile strength of polyester and nylon straps is good, while the cost of polyethylene and polypropylene straps is low, and the resilience of polypropylene is good. Different materials can be used as packing straps.
1, from the production of PP material can be divided into core packing and solid packing belt;
2, from the product quality points can be divided into transparent A-level, transparent B-level, A-level, AB-level, B-level, BC-level and C-level, etc.;
3, from the use of the machine can be divided into manual packing, machine packing belt (also divided into automatic packing and semi-automatic packing belt);
4, from the use of the scope can be divided into packaging with packaging (packing tape) and crafts packing belt;
5, there are other printing and non-printing packing belts and so on.
PET packing belt: Alias ​​plastic packing belt, referred to as plastic steel belt. It is a product that gradually replaces the metal strap. The main component of PET is polyester resin. According to the color can be divided into black plastic steel belt and green plastic steel belt, according to the production process can also be divided into embossed plastic steel belt and smooth plastic steel belt.
So what are the advantages of plastic packaging?
First, high strength: PET plastic steel tape has a strong tensile, close to the same specifications of the steel belt, but also have the ability to resist the impact of the extension, and better ensure product safety.
Second, high toughness: PET packing belt has a plastic characteristic, has a special flexibility, in the transport process can avoid the bump caused by the breakage of the strapping caused the scattering of objects to ensure the safety of transportation.
Third, flexibility: PET plastic steel strip without sharp edges, will not cause damage to the packaged objects. There is no harm to the operator when packing and unpacking, and all unsafe factors are avoided.
Fourth, adaptability: PET plastic strip melting point is generally between 255 °C ~ 260 °C, can maintain long-term between -110 °C ~ 120 °C invariability, good dimensional stability. Because of the material and production process factors, PET plastic steel belt can adapt to various climate changes, and is resistant to high temperature and humidity. Unlike steel belts, it is polluted by rust, pollutes the environment, and loses tensile strength. The strength of the binding is reduced.
Fifth, the appearance is not rust: the steel belt will be exposed to the air and absorb moisture in the air resulting in rust, PET plastic steel belt will not.
