That’s a wrap: keeping crops and the environment safe

Crops need to be protected when they’re young, but existing wrappers are usually non-biodegradable plastic that stays in the environment.

More than 500 films were tested during the research. The different options were analysed for protective properties during the crop’s first four-to-six weeks as well as degradation during the crop cycle to stop them overheating closer to harvest.
