Products displaying this icon are made from freezer-grade polythene that contains an ethylene-vinyl acetate (EVA) additive which prevents the polythene from cracking at low temperatures.
The Food Standards Agency recommends that freezers should operate at around -18°C, at which temperature regular polythene bags will crack up, potentially contaminating the bag contents.
Our EVA additive is an elastomeric polymer that, when added to polythene, makes the material softer and more flexible, whilst improving stress-crack resistance and strength at temperatures as low as -30°C.
This means that you can rely on polythene bags containing the additive - such as our duo-grip freezer bags - to remain fully intact and flexible when placed in your freezer, either at home or in a commercial kitchen.

Yes, we can technically add the EVA additive to any polythene product on request so, if our regular freezer bags are not exactly what you need, but you want something similar, then please get in touch.
Just tell us exactly what you need and a member of the Polybags team will get back to you asap.
Please note: Whilst freezer-grade bags containing the EVA additive are ideal for keeping food fresh in your freezer, you should always follow the freezer guidelines on the packaging for the food in question.
