HF embossing machine supplier.Standard for Judging the Quality of PP Packaging Belt Production Line in Embossing Machine

　　The PP packaging belt production line of the embossing machine is a mesh structure packaging material produced from polypropylene as raw material through heating, melting, stretching, and cooling. The basic parameters that affect the quality of the packaging belt production line include tension, length, curvature, elongation, etc. So, what are the quality standards for judging the PP packaging belt production line of the embossing machine?

　　1. The packaging belt should have good toughness. The PP packaging belt of the embossing machine should be repeatedly folded, and those with poor toughness are easy to break. For pattern issues, the pattern must be aesthetically pleasing and not subject to pressure deviation.

　　2. The quality of the PP packaging belt of the embossing machine is generally white (other colors should be bright), as these are not easily mixed with old materials.

　　3. The PP packaging belt of the embossing machine must have a gloss, and this type of packaging belt is generally produced from various materials. The tension is stable, and if the packaging belt is mixed with powder, the glossiness will be greatly reduced.

　　4. The width error of the PP packaging belt of the embossing machine is generally plus or minus 0.3mm. This type of packaging tape has uniform material and relatively uniform quality in production, and there is no distinction between good and bad.

　　5. Some embossing machines have new material on the outside of the PP packaging belt and fillers sandwiched in the middle (extremely poor). As long as you cut and look at the cross-section, you can see that the black core inside is of inferior quality.
