Parkside, a manufacturer of flexible packaging, has added three new materials to its compostable flexible packaging range to help break through barriers commonly associated with compostable films.
The company said the new materials mark a step-change in its sustainable flexible packaging, which have largely focused on paper-based packaging or industrially compostable films. To complement the existing range, the new filmic structures combine home compostability with performance features traditionally associated with multilayer plastics. Together, the new cellulose-based range of films address major challenges in compostable packaging such as low barrier properties, heavier structures and a reliance on industrial composting.
The move to lighter, more efficient film structures is part of Parkside’s ongoing commitment to innovation, led by the recently expanded New Product Development (NPD) team.
“Consumers are increasingly demanding packaging that can be composted at home, not just in industrial facilities,” said Georgina Merry, NPD manager at Parkside. “Our new structures are designed to compost in a well-managed domestic environment within approximately 26 weeks, making the move to sustainability practical for consumers. In addition, their structure allows for transparent or metallised finishes, alongside high-barrier laminates, for a stronger barrier performance. This, coupled with a reduction in layers to make the overall structure lighter, not only ensures barrier integrity, but also extends their shelf life. These innovations are ideal for customers looking for lightweight, functional and more sustainable flexible packaging solutions.”
To deliver an enhanced oxygen and moisture barrier for sachets and flow wraps, the HCFD6 and HCFD7 were designed by Parkside to incorporate a single functional barrier layer. This cellulose-based structure also offers light protection, making it ideal for snacks and powders.
In order to meet the demands for nutraceuticals, speciality foods and light-sensitive goods, the HCFT1 was created with a dual metallised structure for a high barrier performance. This triplex structure, comprising cellulose and two metallised layers, helps to retain moisture protection, offers a dense barrier matrix for oxygen-sensitive products, and provides strong light-blocking capabilities for UV-sensitive products.
Also in the range is the HCFT2, which features a triplex construction. It is best suited for products with a moderate shelf-life, but has strong oxygen and moisture barrier properties, thanks to its combined cellulose with a metallised and bio-polymer layer.
The company also claimed that all materials are accredited for home compostability under DIN CERTCO – an European standard for home compostable packaging.
Georgina said, “The new materials reaffirm our commitment to ongoing innovation for novel and evolutionary products and, crucially, do not contain conventional fossil-based plastics and therefore are able to meet home compostable standards. This expansion to our sustainable flexible packaging portfolio comes at a critical time in the packaging industry, where changing legislation is now front of mind for many, and businesses must make the right choices to reduce waste and meet consumer demand for sustainable packaging.”
