There is lots of misunderstanding going on with biodegradable bags and compostable bags. Now swiss pac will explain in very simple language the main difference between these two types of bags.
Biodegradable bags : This bags is made with 90% plastic polymers or 10% of additives. These additives are acidic in nature and it slowly starts up eating the plastic. After some time the plastic is eaten up and the plastic is cut into small pieces. But this small plastic piece will not 100% totally compost and become fertilizer. This small little plastic will take years to compost into the soil and will further damage our environment and soil. So biodegradable plastic bags are not 100% environmentally friendly packaging.
Compostable bags : this bag is made with 100% renewal source of products such as corn starch, potato starch, tapioca starch, wheat starch, rice starch, maize starch, or any type of wood pulp etc. This type of bags are truly compostable because after the bags are used and buried in soil the bags starts to become fertilizer and is eaten up by the bacteria and fully becomes soil after some time. We can custom print upto 9 colors and laminate compostable plastic with brown paper and make custom printed compostable bags. We can also make different shapes of bags with or without resealable zippers to catch customer attention.
