The term co-extrusion refers to the technology used to make containers that contain multiple layers in their wall structures. The layers may be made of the same or different materials, coloured or uncoloured material or recycled or virgin materials.
Co-extrusion technology, while not new, is gaining momentum in the industry with the ever-increasing push to provide solutions in sustainability around plastic packaging. Presenting a great opportunity for the inclusion of recycled material in the middle layers, our modern multi-head co-extrusion machines are designed just for this.
We are currently involved in a number of innovative and exciting new projects including the addition of a middle layer of 100% post-consumer recycled material sourced from reclaimed New Zealand milk bottles, to our bottles and containers. These products enable us to reuse plastic from the recycling streams back into a multi-layered container without compromise to top load strength or outer layer surface finish, and with suitable chemical resistance to a variety of products. Best of all, these multi-layer bottles are again fully recyclable!
