The shiny crisp packets and sweet wrappers are made with a piece of aluminium foil sandwiched between two plastic films - the aluminium is used to make the packet more oxygen-proof, this is key because oxygen makes the shelf life of most food go down meaning that the food will go off if exposed to too much oxygen so by making these oxygen proof bags ands wrappers if is increasing the shelf life of the food.
No, if they are PLASTIC bags they cant be made of dolphins
Plastic shipping bags are still being made. Biodegradable plastic and degradable plastic bags are much friendlier to the environment than just regular plastic bags.

Plastic bags are typically made from polyethylene, a type of plastic polymer derived from fossil fuels. The production of plastic bags contributes to environmental issues such as resource depletion, pollution, and habitat destruction. Many countries are working to reduce the use of plastic bags and encourage more sustainable alternatives.
The plastic polymer from which plastic bags are typically made is polyethylene.
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.

well it depends, what crisp packet it is because some are made out of plastic and some are made out of foil.
