Product Description


Pack of 100 A3 size Bio-degradable and compostable bags (With a self seal adhesive fixing strip for quick and easy sealing) .

At last a 'Green' clear display bag for putting your finished prints etc. in for resale.

These bags are made in the UK from film that has been accredited to ‘OK biobased’ and  DIN EN 13432. They are made from annually renewable PLA derived from plant starches (corn / potato etc.) and are fully biodegradable and compostable, breaking down to CO2 and H2O.

Bio-bags are barely distinguishable from their polypropylene equivalents, offering similar clarity, rigidity and protection. However they are slightly less robust - if handled roughly will show white 'stress marks'. These tiny marks often often don't show in use but if you use them for bulky items or they get crumpled up they will show. So they are not suitable or strong enough for very heavy items. 

In normal conditions bio-film bags are quite stable - they may well take years to start degrading. (Our supplier has kept some of the first batch they made from about five years ago and they are still OK. Until they start to degrade we don't have a definitive time scale.)

The main thing to avoid is prolonged exposure to humidity - avoiding excessive heat, moisture and light will maximise shelf life.
(If a bag is splashed with water they don't start to degrade immediately. If wiped off straight away they should come to no harm.)


All our Biofilm bags are made in the UK from film that has been accredited to ‘OK biobased’ and DIN EN 13432. They are made from vegetable starch and are fully biodegradable and compostable, which means that they break down to CO2 and water which can then be reused in the eco system to make new plants. This process can happen in either commercial or home composting or landfill but in commercial composting the temperature will be higher and the process is much quicker. (As a guide, the film specs state that it takes approx. 45 days for them to decompose at a constant 58°C - similar to that found in industrial composting.) The biodegradation process uses naturally occuring bacterial / fungi to break down the film into CO2 and H2O and ecotoxic free biomass (compost). In a colder home composter or landfill this will require the presence suitable bacteria / fungi to start the process and it will just take longer. The time scale will largely depend on the local conditions, it will inevitably take longer to compost in the Highlands of Scotland than it does in Cornwall. 


Our Biofilm (PLA) bags are made from sustainable and annually renewable vegetable starch which is derived from an annually renewable crop, as opposed to petro-chemical based plastics which are non-renewable. Thereby offering a greener alternative to polypropylene etc. without wasting the planets finite supply of petrochemicals and adding to greenhouse gas emissions.
