Processing of Post-Commercial Agricultural Films
When it comes to agricultural film one has to be aware of the many different application areas. As diverse as their usage - as unique and individual the recycling concept and the challenges that must be met so films can become films again. Here is where the technological know-how and experience of LINDNER WASHTECH really pays off. We have supplied many clients from all over the world with machines for this application – tailored to sometimes highly specialised customer requirements.
Agricultural Films
When it comes to agricultural film, no two applications are alike: Whether as green house film, bale wrapping, silo film, strawberry, asparagus or salad film. The contamination degree varies between 20% and 80% depending on the application. The type of soiling also ranges from hay inclusions to soil, sand, stones and strong odours.
The Recycling Solution
As a rule, the aim of reprocessing post-consumer films is to produce new film packaging from the recyclate. Labels and adhesives must therefore be thoroughly removed, especially for the downstream extrusion process - this usually requires a high friction and, optionally, a hot wash. When planning the drying processes, the high proportion of stretch film in particular must be taken into consideration.
