Most commonly plastic bags or made from polyethylene with different densities. An example would be, grocery store bags are made from high-density polyethylene (HDPE) and the shiny shopping mall bags are made of linear low-density polyethylene (LLDPED)
Welll LLDPED is veryh technical more like i cba to work out what it is :D
Bags can be made with a variety of plastics films. Polyethylene (LDPE, LLDPE for example) is the most common. Other forms, including laminates and extrusions can be used when the physical properties are needed. In recent years many countries have demanded the demise or mass reduction in the use of these bags because of their inability to decompose in the ground as waste matter. Now many new producers are using 10 % virgin material such as Polyethylene (LDPE, LLDPE for example) and 90% recycled bags which are mixed in and dissolve in the production process.
Plastic grocery bags are made of non degradable polyethylene.
Plastic. The kind that your purchases are placed in at a store checkout are usually made of polyethylene ("polythene", if you're a Brit).

bags - I am assuming your meaning bags in which to carry things in there are paper, plastic and now the environmental friendly cloth bags. Paper bags are created by using trees - using the pulp in which bags are made from. Paper bags can be recycled. Plastic bags are typically made from oil by-products. Plastic bags can be recycled by it is process is hard. Biodegradeable plastic bags which are not made from petroleum products but derived from our food sources. Cloth bags made from cloth and can be washed and reused. Saving energy and our resources.
