Bio-based composites: A sustainable future
Bio-based composite materials deriving from renewable sources such as plant fibers offer a sustainable alternative to traditional materials. With strength and versatility comparable to traditional alternatives, they minimize environmental impact and promote the circular economy. Despite challenges around scalability and perception, collaborative efforts across industries can achieve their full potential. Adopting bio-based composites is not just about innovation; it is a commitment to a greener, regenerative future for all.
In addition to a wide variety of natural fibers such as flax, hemp and bamboo, the matrix plays a crucial role and bio-based thermoplastic films from Pontacol are ideal for this. Biopolymer films from Pontacol are based on raw materials from castor plants and have a much lower CO2 footprint compared to petroleum-based plastics. These new bio-based matrix films from Pontacol have many advantages, such as less reliance on fossil resources as feedstock, and do not conflict with food production.

These adhesive films, made from 100% recycled carbon, are over 90% bio-based, have a melting range of 185-210 °C and are available in various versions. One with low viscosity that can be used as a matrix material with good tissue penetration and fiber adhesion, or another type that is heat and light stabilized and is ideally used as surface protection with a high UV barrier.
