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 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.
