VTT develops transparent cellulose film to replace traditional plastic in food packaging

Foodstuff packages satisfy their most crucial tasks when they secure food and lessen waste. Thin plastic movies are however complicated to recycle, and they typically conclusion up in the wrong locations soon after use.

VTT has formulated a answer to the problem of plastic packaging. Regenerated or recrystallised cellulose can substitute plastic films.

“We can develop clear and flexible cellulose film. The customer can’t distinguish amongst the crystal-crystal clear material and common oil-based plastic. Cellulose film can resist dampness, but in nature it disappears as entirely as a sheet of paper does. The solution is biobased and biodegradable,” suggests VTT Analysis Professor Ali Harlin.

In addition to their protective qualities, plastics are crucial due to the fact buyers want deals that permit them to see the merchandise alone. Even so, when they have been utilized, a lot of deals are sources of issues.

If a bundle has the two paper and plastic, the buyer may possibly wonder if it can be recycled with cardboard, or if the plastic requires to be torn off very first. Some of the materials have alternating layers of fiber and plastic. Numerous offers are put amongst combined squander by people today who are not able to assume of a better way of disposing of it. Plastic that ends up in a cardboard recycling bin can be taken out, but the plastic normally ends up incinerated.

“The cellulose movie formulated by VTT can switch plastic as a much more weather-welcoming answer. It also makes recycling simple, as it can be put in cardboard recycling alongside with other offers,” says Atte Virtanen, Vice President, Biomaterial processing and items at VTT.

Finland continues to be significantly from the goals established by the EU for cutting down the environmental hurt prompted by plastics. At current about 20 per cent of plastics are gathered, and even a lot less ends up recycled. Under the EU goal, 55 per cent of plastics really should be recycled by 2025.

Plastic movie industry well worth 110 billion pounds

Finland is at the moment far more of a packaging material state than a printing paper place. Last 12 months the value of income of cardboard exceeded that of paper for the very first time. The forest market is seeking for new products with a major market place, which convey benefit-extra. Versatile, clear cellulose movie is 1 this kind of item. The globe market place for plastic movies was about 110 billion pounds past yr.

VTT’s special know-how has been employed in cellulose movie as a alternative for plastic.

“VTT has researched cellulose films for a lot more than 10 yrs, and for a lot more than 6 several years on regenerated cellulose in transparent films,” Virtanen claims.

The creation of packaging materials is in the pilot period, and it could be in intensive industrial use in 5–7 yrs.
