Buy eco-friendly bags
Polybags Ltd. is an UK manufacturer and supplier of environmental bags. Having been on the market for over 45 years Polybags is a high quality plastic bag supplier. In these days is very important to look after the environment and for that Polybags offers biodegradable bags different sizes and shapes. Go and have a look at Polybags biodegradable bags.
What are eco-friendly bags
Environmental bags are made in such a way that its material can biodegrade which is a process by which organic substances are broken down by the enzymes produced by living organisms.
What eco-friendly bags are made of?
Eco-friendly bags can be made from many different sources and materials such as starch based polymers, polyesters (bacteria based polymers), starch or polyester blends, oxo-biodegradable polymers, photodegradable polymers and water-soluble polymers.
Biodegradable plastic bags
Biodegradable plastic bags degrade in a short time when disposed of in special landfills by the action of bacteria, some of the common forms of biodegradable bags include: kitchen waste and refuse bags, bin liners, carrier bags and standard bags.
Differences between degradable and biodegradable
We say that something degrade when very large molecules are broken into smaller molecules or fragments aerobically, that means oxygen is incorporated into these molecular fragments. As the molecules become much smaller they become weak and likely to break as a result of oxidative degradation.
Biodegradation instead is the process by which microorganisms such as bacteria, fungi or algae, convert materials into biomass, carbon dioxide and water.
So the main differences between 'degradable' and 'biodegradable' are first: heat, moisture and/or UV exposure most often causes the degradation of a degradable product, whereas microorganisms degrade a biodegradable product and second: degradable products tend to take much longer to break down into carbon dioxide, biomass and water.
When degradable plastics break down into smaller molecules, eventually they will be small enough to be consumed by microorganisms and so biodegradation occurs. In essence then, all degradable films will eventually biodegrade but at different speeds.
