Heat Shrink Film
A certified highly transparent eco-friendly compostable heat shrink film has also been created by ECO365 Compostable. This shrink film goes back to nature as compost once composted within 60 to 180 days.
Food packaging innovations and sustainability
- Compostable laminate
- Corn protein
- Cellulose 'pomace'
- Wood foam packaging
Most companies are looking to cut down their environmental impact. In France, fruit and vegetables sold in plastic packaging is now banned from January 2022 onwards. However, in some businesses, plastic packaging is still favoured, so those brands may be needing to explore recyclable plastic solutions if they want to avoid any potential backlash from eco-conscious customers.
Plastic packaging waste is a big problem for the environment so therefore businesses are looking for ways to eliminate plastic packaging for food. Here are some new packaging materials entering the market:
Compostable Laminate
Minton’s Good Food have introduced home compostable packaging to replace their non-recyclable plastic packaging. This duplex compostable laminate is said to break down within 26 weeks in a home composting environment so that it is beneficial for the environment as well as providing an eco-friendly product for eco-conscious consumers.
Corn-based material
A biodegradable, bacteria killing food packaging made from corn protein and other naturally derived biopolymers has been developed by a team of scientists. This plant-based waterproof packaging made from corn protein called Zein is infused with natural anti-microbial oils that can extend shelf life of fresh fruit by up to three days more than traditional plastic containers.
When the packaging is exposed to an increase in humidity or enzymes from harmful bacteria, the fibres in the packaging release the natural anti-microbial compounds killing common dangerous bacteria that contaminates food. The material is said to have the potential to be used on a wide variety of fresh food products including ready-to-eat foods, raw meat, fruit, and vegetables!
Next to this, there are currently developments to use the by-product of as part of thermal insulation solutions. Even though, the solution is not yet on industrial scale, the developments are encouraging and driving the market in the right direction.
Wood Foam Packaging
Wood foam is another packaging material approaching the market and is developed by researchers at the Fraunhofer Institute for Wood Research in Brunswick. The aim is for wood foam to be used as a sustainable replacement for cushioning and insulating products. This is because it consists of 100% renewable resources, is climate friendly, and recyclable. In just a few years, it is said the large-scale industrial manufacture of wood products made of wood foam should be established in the market.
Cellulose coating made from 'pomace'
No more plastic packaging for fruits and vegetables could soon become a reality for everyone and not just those in France! Empa researchers teamed up with retailer Lidl Switzerland to develop an alternative cellulose coating for fruit and vegetables made from ‘pomace’ – squeezed fruit and vegetable peels! This means it can reduce packaging and prevent food waste.
New Paper Packaging Materials
- Honeycomb packaging
- Insulated packaging made from recycled paper
- Paper-based bottle made from waste
While paper material in itself is not new, the growing need for flexible packaging materials is making the paper packaging materials market pick up pace. Paper packaging materials are witnessing huge demands in the pharmaceutical, food and drink, and cosmetic industries which is further driving the growth in the market.
This is because paper-based packaging is versatile and a cost-effective method that protects and preserves a wide range of products. With the industry being hit by supply chain issues and massive corrugate shortages over the past year, the demand has not been easy for the packaging industry to handle – which you can read all about in one of our latest articles.
