Best Trash Bags for Odor Control

Why odor control claims vary so much

Odor control in a trash bag usually comes down to one of two approaches. A scent can mask smell, or a compound can neutralize it at a chemical level. Baking soda, the ingredient behind Arm & Hammer’s odor technology, works by neutralizing acidic and basic odor compounds rather than covering them up. A pure fragrance masks odor instead of breaking it down, which is a different mechanism with a different result once the scent itself fades. None of the manufacturers in this guide state which category their own claim falls into with that level of detail. What follows is what each brand’s own page actually says, not our own lab conclusion. If you’re trying to figure out what size bag and how many you’ll actually need, our trash bags calculator has that math.

Our pick: Glad ForceFlex MaxStrength, Fresh Air Scent

Glad ForceFlex OdorShield bags carry a specific, quantified claim. The manufacturer states four days of odor control, and that the bag “neutralizes trash odors” rather than just masking them.

The bags are made of polyethylene, and Glad’s own page states the bag itself isn’t recyclable or compostable. That’s a direct disclosure, not something buried in fine print elsewhere on the site.

Runner-up: Hefty Ultra Strong Kitchen Trash Bags

Hefty’s claim is built around a named ingredient rather than a duration. The bags use what the manufacturer calls Arm & Hammer Continuous Odor Control, a patented odor neutralizer licensed from Church & Dwight, the company that makes Arm & Hammer baking soda. Hefty doesn’t put a number of days on the claim the way Glad does. Both are still manufacturer marketing claims, not something either brand submits to independent testing that we could find.

Also consider

simplehuman doesn’t make an odor control claim on this product’s own page at all. What it sells on instead is fit. Its Custom Fit Liners are sized to specific simplehuman trash can codes rather than a generic gallon capacity, which means they aren’t interchangeable with a standard 13-gallon can the way the other three products in this guide are. The liners are made with 50% post-consumer recycled plastic, per the manufacturer.

What Seventh Generation sells on instead

Seventh Generation’s trash bags don’t make an odor control claim either, for a different reason. The product is explicitly unscented by design, with nothing added to mask or neutralize smell. What Seventh Generation discloses instead is recycled content. The bags are made with 55% post-consumer recycled plastic, built with what the manufacturer calls Greencore 3-Layer Technology, which sandwiches the recycled material between two layers of virgin plastic for strength. The company also states it’s a founding B Corporation, dated to 2007.

Scented or unscented?

On the pages we read, an odor claim comes with a scent. Hefty says so most directly. Its Ultra Strong large bags offer the “Arm & Hammer patented odor neutralizer on scented bags” and list a “Scent Free” option beside them, so the neutralizer claim covers the scented bags only. Glad’s odor claim is made for a scented bag, Fresh Air. Its unscented Heavy Duty Large Quick-Tie page makes no odor claim at all. Seventh Generation’s bags are unscented and make none either.

So if you want a bag with an odor claim behind it, you’re choosing a scented one. If you’d rather not have added scent, none of the unscented bags here claims to control odor.

How Glad’s odor claim compares to other brands

Glad makes the most specific odor claim of the four brands we compared. Its product page promises four days of odor control and says the bag neutralizes trash odors. Hefty’s page names a neutralizer, Arm & Hammer Continuous Odor Control, and gives no number of days. simplehuman and Seventh Generation make no odor claim on the pages we read.

So on paper, Glad says the most. That comparison is about what each brand claims. We found no independent test of how well any of these bags holds in smell. If odor is your main concern, Glad and Hefty are the two brands with a claim to weigh. If you’d rather avoid added scent, Seventh Generation’s bags are unscented by design.

How we researched this

Every fact in this guide comes from each brand’s own website. That means product pages and stated compatibility claims, retrieved directly, not through any retailer listing or third-party review site. The B Corp certification listed for Seventh Generation reflects the company’s own stated status, not a per-product directory match. Where a brand’s own page makes no claim about odor control, this guide says so directly rather than assuming a reason. No prices are shown. Every retailer link goes to a search results page for the exact product, not a specific listing, so it stays accurate regardless of what’s currently in stock.
