Packing band alias PP strapping. Packaging with packing strap (binding belt) system to polyethylene, polypropylene resin as the main raw materials, but also to nylon and polyester as raw materials, extrusion one-way stretching system. Plastic strapping belt has good elastic recovery, high strength, good water resistance, strong chemical resistance, light and soft, which can be tied up and machine strapping. Easy to use, low cost, can be made into red, white, blue, yellow, green, and other colors, according to the color binding of different grades of goods, easy to distinguish the grade of goods, improve delivery efficiency. In addition to paper core sealing strapping, but also strapping material, fruit and so on. The tensile strength of polyester and nylon strapping belt is good, while the cost of polyethylene and polypropylene strapping belt is low, the resilience of polypropylene is good, and the strapping belt of different materials can be selected according to the need. The plastic strapping belt is divided into two types according to the use method: machine belt (J type) and manual belt (S type).
Packaging strap is a widely used consumable packaging material. It can be classified from different aspects:
1, from the production of PP material quality can be divided into core and solid core belt; 2, from the quality of products can be divided into transparent A, transparent B, A, AB, B, BC and C, etc.; 3, from the use of the machine can be divided into hand belt, machine belt (also divided into full automata belt and semi-automata belt); 4, from the scope of use can be divided into packaging belt and crafts belt; 5, there are other printing and non-printing tape and so on.
1: bend the left end of the packing belt, insert the packing buckle, and then fold the left fixed rod into the packing belt and tighten it.
2: Hold the packing belt with the right hand to bypass the packaging, bend the right end of the packing belt into the packing buckle, and fold the left fixed rod into the packing belt.
3: Fix the packing buckle with the left hand, and press the right end of the packing belt with the right hand to tighten the packing buckle.
4: Finally hold scissors to cut the packing belt.
The packing belt is made of a mixture of PP and PET plastics. Main production process: plastic particle melting — pressure tape —- molding —- cooling —– winding —- packaging – storage packaging tape system using polypropylene through heating, melting, stretching, cooling produced by the network structure of packaging material, the basic parameters that affect the quality of packaging tape are tension, length, bending, elongation and so on. In the case of the same tension and other parameters, the longer the length, the lower the cost.
