A compostable Bag with self seal flap for A4 cards and envelopes, or artwork - made from 30mu Nativia ® film.

Nativia ® film is made from corn or other sources such as sugar beet and potatoes among others, and conforms to the EN13432 standard, meaning it is biodegradable and compostable. It has also achieved the OK Biobased certificate from Vincotte. Nativia ® film breaks down quickly into carbon dioxide, water and biomass by microbial digestion in the right conditions.

The film is sourced from renewable sources and is food safe.

The film manufacturer recommends that the bags are used within 6 months and stored in suitable conditions - away from local heat sources, out of direct sunlight and below 30 degrees Celsius.

This bag now comes with a compostable notice in green on the flap.

Nativia ® can be industrially composted and will disintegrate in six months to CO2, water and humus, a soil nutrient. It can also be mechanically and chemically recycled (not with other plastics because it has a lower melting temperature) and it can be incinerated. Nativia ® films do not biodegrade in landfill conditions.

How long will these bags take to decompose?

The film that these bags are made from has the EN13432 certification. EN 13432 requires compostable plastics to disintegrate after 12 weeks and completely biodegrade after six months. That means that 90 per cent or more of the plastic material will have been converted into CO2. The remaining share is converted into water and biomass – i.e. valuable compost.

How should I dispose of these bags?

These bags are industrially compostable, so they can be disposed of along with other industrially compostable materials like garden waste in green bin collections, or sometimes food waste. You will need to check the arrangements in your Local Authority though as arrangements do vary across the country.

I’m thinking of switching from Polypropylene bags to these – what are the main differences?

Apart from the environmental credentials which speak for themselves, these Nativia ® bags will feel slightly different. The film is a little stiffer, although still very clear. We recommend that you have a sample of the bag before switching, to make sure they will work for you.
