Six pack rings

Six-pack rings have been manufactured to be 100% photo-degradable

Six pack rings or six pack yokes are a set of connected plastic rings that are used in multi-packs of beverage, particularly six packs of

since 1989, six-pack rings have been manufactured to be 100 percent photo-degradable, so the plastic will begin to disintegrate in just a few days, allowing animals to easily free themselves from the brittle and crumbling rings.

Since the late 1970s, six pack rings were cited as a particularly dangerous form of marine litter as marine wildlife were found entangled in the rings, sometimes strangling to death. But since 1989, six-pack rings have been manufactured to be 100 percent photo-degradable, so the plastic will begin to disintegrate in just a few days, allowing animals to easily free themselves from the brittle and crumbling rings. This is in accordance with the U.S. Federal regulation for testing plastic photo-degradation, which is 40 CFR Ch. I (7–1–03 Edition) PART 238.

Six-pack rings are a relatively minor contributor to marine litter and wildlife fatalities. Fishing gear and other plastic wastes are a larger problem.
