Processing of 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.
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.
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.
Regarding the agricultural film, no two applications are alike and range from greenhouse film, bale wrap film, silage film, strawberry, asparagus or salad film (mulching film). The contamination degree varies between 20% and 80% and can include dirt such as hay inclusions, sand, and stones and a strong and pungent smell.
