The tying materials in the package mainly include plastic strapping (also referred to as strapping) and plastic ropes, which are mainly used for corrugated cartons and other bulk foods and vegetable packaging. Its role is to bundle the packaged goods together, compress the volume, increase the strength of the package, and facilitate loading and unloading. There are also seals, anti-theft, and the role of preventing the loss or scattering of the package.
China Packaging Network experts pointed out that when packaging any item, no matter what kind of material or container is used for packaging, there is finally a problem of sealing or tying the package. The materials used to seal packaging containers are called packaging and packaging materials, and various materials for packaging products and combination packages are called packaging and binding materials.
Inner packaging, outer packaging, large packaging, and small packaging do not have the same purpose of sealing and binding, but their role is nothing more than the following aspects:
1: Prevent the contents from coming out, leaking, and dissipating;
2: Prevent the product from oxidation, corrosion, etc., extend the life of the product and increase the value of the product. 3: Prevent the contents of the product from being contaminated, be stolen, or be stolen;
4: Strengthen the strength of packaging containers, and sometimes have the effect of beautifying goods;
5: easy to store and handle.
The plastic strapping tape for packaging is made of polyethylene and polypropylene resin as the main raw materials, and nylon and polyester are also used as the raw materials, which are obtained through uniaxial extrusion. The elasticity of the plastic banding belt is good, the strength is high, the water resistance is good, the chemical resistance is strong, the quality is light and soft, and it can not only be bundled but also be bundled by machines. Easy to use, low cost, can be made of red, white, blue, yellow, green, and other colors, according to the color bundle of different grades of goods, to facilitate the classification of goods, improve delivery efficiency. In addition to the sealing and strapping of corrugated boxes, it is also possible to tie materials, fruits, etc. 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. Binder straps of different materials can be used as required.
The plastic strapping is divided into two types according to the use method: machine belt (J type) and manual belt (S type). The model name of the strap is material, the nominal size and type of width and thickness are distinguished: The strap is widely used Food, pharmaceuticals, home appliances, daily chemical, light industry, electronics and many other industries.
Experts pointed out that today's market economy is very active today. Any enterprise can not do without packaging. In recent years, with the continuous demand for the production of large, medium and small enterprises, the demand for packaging has grown rapidly. As a supporting material, the packaging industry has developed in the national economy.
