The collapse of plastic packing belts during use is often encountered, so what causes the collapse, we need to understand clearly, and then avoid it. One is that the reserved length of the welding joints of plastic packing belts is uneven, and the length of the belts is unevenly tied, resulting in uneven force. Secondly, the welding time is too long, forming a virtual weld, or causing the strap to become thinner and reducing the tension. In addition, insufficient welding time, incomplete welding, misalignment of packing belts at the welding port, left and right misalignment, reduced overlapping area, and reduced tension are all possible reasons. Of course, there may be other reasons. In short, we must do a good job in its quality inspection when using it.
In addition, because the product is also affected by the environment, we should take into account different environments when using it, and do a good job of maintenance accordingly, to better exert its effect.
Plastic packing belts have good elastic recovery, high strength, good water resistance, strong chemical resistance, lightweight and softness, and can be tied by hand or by machine. Easy to use and low cost, it can be made into red, white, blue, yellow, green, and other colors, and goods of different grades are bundled according to colors, which is convenient for distinguishing the grades of goods and improving delivery efficiency. In addition to being used for the sealing and bundling of corrugated boxes, it can also be used for bundling materials, fruits, etc.
The tensile strength of polyester and nylon strapping is good, while the cost of polyethylene and polypropylene strapping is low, and the resilience of polypropylene is good, and strapping straps of different materials can be selected according to needs.
Plastic strapping is divided into machine straps (J type) and manual straps (S type) according to the usage method.
