Bags increasingly replace metal tins and rigid containers. The market research institute Ceresana analyzed the European market for flexible packaging made from plastics, paper, and aluminum.

Linear low density polyethylene (LLDPE) is the most versatile type of polyethylene. Large amounts of this plastic are used in the production of films in particular. Global revenues generated with LLDPE amounted to US$ 40.0 billion in 2013. A new study of the market research institute Ceresana expects global market value of LLDPE to increase by about 3.9% p.a. until 2021.

Low-density polyethylene (LDPE) is one of the most commonly produced plastics and mainly used for packaging. According to a new study published by the market research institute Ceresana, low-density polyethylene worth almost US$33 billion was sold worldwide in 2013. Ceresana expects global sales to rise by 1.5% p.a. until 2021.

Plastics bags are increasingly attacked by environmental activists and legislators alike; yet at the same time consumption of plastic packaging rises.
