At Chinaplas 2014, recycling technology group Starlinger is exhibiting a method for turning production waste from polypropylene tape lines into useable masterbatch, as well as a system for turning recycled PET and HDPE into food-contact approved materials.
Waste from polypropylene tape production is clean and homogenous, and is relatively simple to recycle, says Starlinger. With recoBATCH, the name the firm has given to its system, users can upcycle the waste by adding calcium carbonate. This can then be used to substitute some of the new masterbatch required in the tape production process.
The group is showing a recoSTAR universal 65 VAC recycling line with the recoBATCH option at in Shanghai.
Starlinger is also displaying its viscotec line, set up with a deCON 20 decontamination dryer, for processing flakes and recycled pellets from PET and HDPE for use in food grade packaging. The deCON 20 dryer can process input material in different forms – e.g. pellets, flakes etcetera – simultaneously. The process is compliant with the relevant FDA and EFSA standards, says Starlinger, meaning that the material can be used for food grade packaging.
Also designed for the food packaging market is the firm’s viscoSHEET line, which produces thermoforming sheets for food packaging from up to 100 percent recycled PET.
