Thermoplastic composite sheet
Architectural interior wall panel from recycled wood and biopolymers
An alternative to conventional High Pressure Laminate (HPL) systems, this bio-composite sheet potentially replaces HPL as top layer for plywood. Its recycling is easy, it can be made of recycled materials, it is more cost efficient,and no adhesive is needed during hot-pressing onto plywood.
