Six-pack rings

Invented in the 1960s, within 10 years, plastic rings had completely replaced the paper and metal-based holders then common in the market.

Though interest in multi-packs has continued to grow, other variations, including paperboard baskets and LDPE plastic can carriers, have grown in popularity, providing an alternative to conventional six-pack rings.

[3] Compared to fishing gear, cigarette butts and other plastic wastes, six-pack rings are a smaller contributor to marine litter.

[7] In 1994 The US Federal Regulation proposed that all plastic ring carriers be naturally degradable materials, applying to all importers and processors.

[10] In 2018 Carlsberg Breweries announced the use of a new type of glue, which took three years to make, that would hold their beers together instead of plastic rings.
