simplehuman's odorsorb custom fit liners are carbon-infused to naturally adsorb odors. These sustainable liners are made with 50% post-consumer recycled (PCR) plastic, keeping material out of landfills and oceans, and carbon out of the atmosphere. The odor-absorbing liners are also designed to fit each compatible can perfectly so there is no messy bag overhang or bunching — and they never slip. Extra-thick plastic and double-seam construction prevent rips and tears, even if you pack trash to the rim. Quick-dispense packs make it easy to grab liners one-by-one without messy unraveling. Refill packs are designed to fit perfectly inside sensor and step cans with the built-in liner pocket system for a faster liner change.
