Compostable and renewable packaging film specialists Futamura grabbed headlines at Packaging Innovations 2018 in London with its 100 percent plastic-free, compostable crisp bag made from barrier film NatureFlex. The bag is the first of its kind on the European market, originally launched in Germany. Futamura collaborated with packaging manufacturer Bio4Pack to create the pack for German organic crisps producer, myCHIPSBOX. The bag was displayed on the Packaging Innovations Showcase as well as the Futamura stand.
“To make a product which is as sensitive to moisture and light as crisps and package it in non-plastic materials is a real technical challenge,” explains Sweetman.
“What we have here is a laminate of two different materials: NatureFlex on the outside providing the barrier properties, laminated to another material on the inside which is giving perfect seal integrity.”
“So although we are using two different materials, what they have in common is that they are both compostable, providing an option for end-of-life reuse of the material through composting, whereas otherwise conventional plastics will not be recyclable.”
Beyond crisps, the pack can also be used for other foods. Sweetman continues: “The bag can be used for any kind of dry foods. All different food products have different technical needs but with NaturaFlex material, we can actually modify the barrier properties depending on the specific needs of those food products.”
“For example, we can package for cheeses or baked goods with might need some permeability. With foods like potato chips, cookies biscuits and so on, that’s where we deliberately make the materials very much more barrier proof to moisture.”
Sweetman describes how this product is the first of its kind on the European market, but that the concept can go much wider: “We can go pretty much worldwide,” he says.
“Certainly in the Americas there are a lot of packs using similar types of constructions already for potato chips.”
“Two or three years ago, this type of pack wasn’t possible. It’s the introduction of higher barrier materials from us and metallization techniques which allow us to achieve these kind of properties, so it’s very much a development of the last two or three years,” Sweetman concludes.
The supplier’s bio-films are manufactured using renewable resources, predominately wood-pulp from managed plantation) and are certified to the European (EN13432) and American (ASTM D6400) norms for industrially compostable packaging.
In addition, the majority of grades have been certified by TÜV Austria to the OK Compost Home standard for home composting and certain grades have been proven to biodegrade in a waste-water environment. Further testing has proven that most NatureFlex grades are also suitable for anaerobic digestion.
Futamura’s 100 percent compostable bag captured the general atmosphere of the show as the debate around plastic packaging and its alternatives played out, quite literally, during a much-anticipated plastics debate involving several UK industry leading figures. Meanwhile, A Plastic Planet exhibited a plastic-free aisle with a number of compostable and biodegradable plastic-alternative packages.
