This sandwich panel has a core of PLA based hexagonal honeycomb made in a continuous production process. Only moments after the core is produced, skin layers are added in a second step of the continuous production process. These skins can be made from unfilled PLA material to make a mono material panel or, in case a higher performance is required, can be replaced with consolidated flax in a PLA matrix.

Poly-Lactic Acid (PLA) is a biopolymer used to make for example packaging, consumer goods and furniture and is derived from renewable resources instead of oil. A biopolymer offers more disposal options and is more environmentally friendly to manufacture than traditional petroleum-based plastics. Derived from 100% annually renewable resources, PLA generates significantly less greenhouse gas emissions over the life time when compared to traditional materials like PP.
