Benefits of Recycling Plastic Film and Bag Production Wastes In-house

Due to the large size of productions of 15 years old fast-growing bag manufacturer for many different companies, the scraps generated from plastic flexible packages, patch and soft handle bags, punched-out handle bags, courier bags, exam bags, gift packages, shrink films and document pouches were considered as high. The bag producer needed to work with several professional recyclers to reprocess them.

In-house recycling, in another word post-industrial recycling, is an escalating trend among plastic manufacturers around the world as well as in Türkiye. Istanbul, Esenyurt based plastic flexible package and courier bag producer Sürmeli Plastik has also started to recycle its own production wastes within the factory by Repro-Flex 100 .

Being unable to have full quality control over recycled pellets, and costs occurring from storing, logistics, and outsourced recycling; the bag producer considered starting in-house recycling on by own.

Which Machine is Most Suitable for In-house Recycling?

The plastic scraps from the cargo bags, shopping bags and gift bags to recycle are made of several variations of PE materials, and contain OPP and PP adhesive tapes on them. Moreover, these plastic scraps are clean (not contaminated by dirt, oil, etc.), dry (no moisture from the washing lines) and have varied printed surface. Some of the bags are slightly printed, and some of them have up to 50% of printed surfaces.

Among them, the final pellets quality found stable and satisfactory from the two recyclers who are using POLYSTAR Repro-Flex plastic recycling machines.
