A Knapsack is a transparent bag that you can use for a Knapsack holder. With this bag, you collect plastic packaging such as foil, PE packaging, PET bottles or plant pots. Because of the transparency of the Knapsack, you directly see the content of the bag. For every Knapsack holder we have (multiple) matching Knapsacks. From 60 liter up to and including 2500 liter. Perforated, unperforated, in different colors and materials.
Our Knapsacks are made of recycled or new material: LDPE (Low Density Polyethylene) and MDPE (Medium Density Polyethylene). At each product description it is indicated from which material the Knapsack is made from and whether the bag is perforated or not.
Difference LDPE and MDPE
The main advantage of LDPE material is that it is often made out of recycled material. We have bags in two different kinds of LDPE: virgin (new) and recycled material. Our future perspective is to only use recycled material for our bags. This could have the effect that some bags are cloudier than others. This depends on the material that is available at that moment
Which micron you choose depends on which waste stream you want to collect. If you only collect foil, you should choose a lower micron than when you collect plastic bottles. With plastic bottles a higher micron is needed, since this waste is thicker and heavier. The material is transparent, but can be made into various colors.
MDPE is made of virgin (new) material. The advantage of MDPE is the higher tear resistance and there is less material needed to produce the same quality of bag as LDPE. The bag has a cloudy white color.
