A paper bag is a bag made of paper, usually kraft paper. Paper bags can be made either with virgin or recycled fibres to meet customers demands. Paper bags are commonly used as shopping carrier bags and for packaging of some consumer goods. They carry a wide range of products from groceries, glass bottles, clothing, books, toiletries, electronics and various other goods and can also function as means of transport in day-to-day activities. Paper bags are highly biodegradable and recyclable, and hence does not pose the same environmental footprint as plastic bags do. The fibres are reused 3.6 times on average in Europe, while the world average is 2.4 times. Plastic or water-resistant coatings or layers make recycling more difficult. Paper bag recycling is done through the re-pulping of the paper recycling and pressing into the required shapes.
