This depends on the bag. For example:
The d2w™ rubbish bags, sacks and bin-liners are totally degradable and strong. They can be used to dispose of all forms of household and garden refuse.
Polythene combined with an additive that makes the material degradable.
The polythene is formed into a thin, tubular film using standard extrusion methods. It is printed at the same time. This film is then sealed into bag lengths and perforated using a stamping process, so that the bags can be torn off easily.
All plastic bags are potentially dangerous to small children. However, compared with other polythene bags, which are either non-degradable or partially degradable and which actually prevent decomposition, the d2w™ bags are much more acceptable environmentally. As they degrade, they don't litter the countryside, harm animals or marine life, produce harmful substances or fill up landfill unnecessarily.
The bags come in a variety of sizes and are easy to use.
