Water-Bottle Cap Is Totally Biodegradable

摘要

A new LDPE water-bottle cap formulated with a proprietary additive is said to completely biodegrade in five to 10 years. The additive also maintains clarity and tensile strength. Called the Earth Cap and molded by Norland International Inc., Lincoln, Neb., at its plant in the Far East, the injection molded, 55-mm cap is said to be a first for 5-gal water bottles. It also has a first-of-its-kind biodegradable, non-adhesive, tamper-evident label and 2-mm foam seal, making the entire cap structure totally biodegradable.
