The quantity of packaging belts used in the packaging industry is very large. There are nearly a thousand production lines in the Guangdong market, which are mostly produced using waste materials. There are many impurities and frequent screen changes, and all of them are manually shut down and replaced, resulting in a large amount of recycled materials and waste materials, which can easily form a vicious cycle. The strength of waste materials is inherently low. Recycling consumes energy, wastes labor, and the quality of reproduction products will also be reduced.

PP box strapping plant screen changer

Characteristics of PP box strapping plant process:

1. High requirements for product dimensional accuracy and mechanical properties;

2. Usually using recycled resin or adding partially recycled resin;

3. Usually, PP or PET resin systems are used;

4. PET resin has low viscosity and is easy to crystallize;

5. The fluctuation of melt pressure can easily cause flow interruption or shutdown;

6. Product impurities and bubbles can easily cause obvious defects and quality issues.

PET box strapping plant screen changer

Features of PET box strapping plant screen changer:

1. Optimize the structural design, achieve the functions of preheating the filter and discharging the material, completely eliminate the fluctuation of melt pressure and temperature during the mesh changing process, and design multiple heating methods to ensure the stability of resin pressure and material flow during the mesh changing process;

2. Improve product plasticization, reduce resin loss during mesh replacement, and reduce usage costs

3. It also has a super large area and self flushing function.
