Pp Strapping production process: melting of plastic pellets --- belting --- forming --- cooling --- winding --- packaging -- storage. The PP Strapping system is a packaging material with a mesh structure produced by polypropylene through heating, melting, stretching and cooling. The basic parameters that affect the quality of PP Strapping are tension, length, bending, elongation and so on.
Under the same tension and other parameters, the longer the length, the lower the cost. PP Strapping has introduced four of the world's most advanced Packing Belt production lines, using processing technology to produce high-strength, high-quality, environmentally friendly 3,000-meter new material PP Strapping. The unit price per meter is much lower than that of domestic return belts and similar imported belts. unit price.
There are the following criteria for judging the quality of PP Strapping machine:
1. The quality of PP balers is generally white (other colors should be bright), because these are not easy to mix old materials. 2. Some balers are made of new material on the outside, and the filler is sandwiched in the middle (extremely poor). As long as you cut it and look at the section, you can see that the black heart inside is of poor quality. 3. The baler belt should have gloss, and such baler belts are generally produced from all materials. The pulling force is stable. If the baler is mixed with powder, the gloss will be greatly reduced. 4. The baler belt should have good toughness. Fold the PP baler belt repeatedly, and those with poor toughness are easy to break. For the pattern problem, the pattern must be beautiful, and there should be no pressure deviation. 5. The width of the baler belt, the width error is generally plus or minus 0.3mm. Such a baler belt is uniform in material and quality, and the quality will be relatively uniform, and there will be no good or bad situation.
