What is it?
Created using a unique recycling technology that turns materials that previously were very hard to recycle into a strong cellulose fibre-reinforced composite material.
B40 is a mixture of:
57% multi-layered plastic film waste
40% plastic-coated paper carton waste
Multi-layered film is used for flexible food packaging for chips, soups, candy, chips, sliced meat, and many other categories of food. The plastic film can consist of up to 12 layers of different types of plastics but most often the majority is polyolefin, e.g. polyethylene and polypropylene.
The advantage of multi-layered film is its enhanced mechanical properties and its ability to significantly increase the shelf life of the food product. However, it is difficult to recycle because the individual layers cannot be separated or sorted by common mechanical recycling technologies.
The other component used to create B40 is plastic-coated paper carton, which is a laminate of paper, aluminum foil, and several layers of plastic film. The material is used for the ubiquitous Tetra Pak beverage, milk, and food cartons. Plastic-coated paper carton is also difficult to recycle because the individual layers cannot be separated.
The moulded sample in the PositivePlastics material sample kit is made from post-industrial recycled materials, but it is also possible to use post-consumer recycled materials, if the materials are cleaned thoroughly before processing.
B40 is manufactured by processing coated paper cartons using a new patented recycling technology that breaks the aluminum down into very small pieces and separates and distributes the cellulose fibres within the paper, so there are no residual paper fragments left. The resulting material is mixed with molten multi-layered plastic film and additives. The cellulose fibres significantly increase the tensile strength and rigidity of the material.
Flexural Modulus (MPa): 2000
Tensile Strength (MPa): 43
Strain at break (%): 7.5
Izod Notched Impact Strength, +23°C (kJ/m2): 5.0
Density (kg/m³): 1.06
Melt Mass-Flow Rate (230°C,5kg g/10min): 4.1
The mechanical properties of this material are on the same level as most unfilled virgin engineering plastics, such as ABS or PBT, and can in certain applications be considered a replacement for them.
Look and feel
The material has a nice matte surface, and you can see the evenly distributed metallic flakes from the shredded plastic-coated paper carton within the plastic. The natural colour is dark grey and it can be coloured to produce other dark shades of blue, green, red, etc.
Because of the difficulty in recycling, a high percentage of both post-consumer plastic-coated paper cartons and multi-layered plastic film is incinerated or landfilled. This new process enables the recycling of these materials into a cellulose fibre-reinforced plastic composite that can replace virgin fossil-based plastics in many applications, while contributing to the reduction of CO2 emissions.
