As part of an EU research initiative, the Paint Research Association has created a new food packaging product which could replace the current coatings used which involve petrochemicals, a hazard to the environment in a number of ways. PlantPack, the new development, is both eco-friendly and can be applied to paper or cardboard materials as a spray-based product, making it great for a range of containers and wrappers.
The director of PRA, Ian Claris, stated that PlantPack offers a real breakthrough for packing technology, providing not only a cost-effective solution for packaging companies but also a sustainable alternative to the current coating products. The development is biodegradable so it can be recycled easily, becoming an eco-friendly offering to replace those currently on the market. As global warming becomes an increasing issue, more and more companies are seeking out safer options for the environment.
Packaging coatings are used in a variety of companies, from cartons to paper wrappings – coatings are used to provide a barrier between the container and the product. PlantPack is developed from seaweed extracts – these are new to the packaging industry, although they have been used as a sustainable source for other food and pharmaceutical products. The downside to seaweed is that it isn’t the strongest of materials, making it difficult to mould or reform. Researchers have overcome this issue by combining seaweed with starch derivatives to create a sturdy and flexible coating that can be applied to different materials.
This new development looks set to provide a sustainable and recyclable alternative to current package offerings, which consist primarily of petrochemical-derived polymers and waxes. Though effective, these are costly, damaging to the planet and increase the risk of volatility in oil-producing countries. As the food packaging industry seeks out a reliable alternative, PlantPack could be the answer to a number of questions.
