The workhorse gauge in the workhorse size: 1.5-mil low-density liners cut 40x46 for the Brute-class cans that anchor every custodial route, US-made, a hundred to the case. This is the collection-point liner most facilities should be running.
Editorial rating: 4.5/5. The middle of the liner program done right: honest gauge, standard size, domestic supply chain.

Who it's for
Central collection points, kitchens, and mixed-waste routes — the cans that take whatever the floor produces, most of which isn't sharp but all of which is heavy.
Skip it if
Deskside paper waste (HD liners do it for a third the cost) and true debris (that's the 3-mil class).
How it fits the facility safety program
Waste containment is exposure control: right-sized, right-density liners keep sharps, liquids, and biohazard surprises inside the bag per the handling expectations that flow from OSHA's sanitation and bloodborne rules. Density to waste stream, size from the can's math. New to the department? Start at the janitorial & facility safety collection overview.
How it compares
vs Aluf 16-gal HD: the deskside half of the two-SKU program. (Our take: full Aluf 16-gal HD review.)
vs Tasker 3-mil: the step up when debris appears. (Our take: full Tasker 3-mil review.)
Pros and cons
Pros
- 1.5 mil is the honest mixed-waste gauge
- 40x46 fits the 44-gal Brute math exactly
- Made in USA for domestic-sourcing policies
Cons
- 55¢/liner vs pennies for HD on light duty
- 100-count case runs out faster than it feels
- Black film visibility trade again
Build out the facility program
One product is a purchase; the program is what protects people. Map every dispenser-to-refill pairing in the dispenser compatibility guide, size every can with the trash liner calculator and the mil & micron decode, and rank the categories in our best-of guides for commercial paper towels, can liners, and wet floor signs. The safety context lives in the custodial worker safety hub with its floor stripping and cleaning chemical safety guides. Crews need nitrile gloves, chemical-resistant gloves, splash goggles, and slip-resistant footwear; liquid failures belong to spill control. Browse the department: janitorial & facility safety, paper towels & dispensers, trash can liners, wet floor signs — case-lot orders via bulk & business orders.

Janitorial & facility supply FAQ
General questions about ratings, OSHA limits and fit are answered in the dispenser compatibility guide guide.
How we review
WC Safety reviews are spec-honest: we work from the manufacturer's published data and the live Amazon listing, flag any claim that exists only in listing copy ("per the listing"), and never invent certifications or test results. Ratings are editorial judgments about fit-for-duty at the captured price — not aggregated user scores.
Sources
Manufacturer product pages and the Amazon listing linked above; OSHA 29 CFR 1910.22 (walking-working surfaces), 1910.141 (sanitation), 1910.1200 (hazard communication) as referenced; our own category testing of dispenser-refill pairings documented in the compatibility guide.

Common questions
How do I know the plug is actually sealed?
The occlusion effect: with the plug seated, your own voice sounds boomy and hollow and ambient noise drops obviously. If speech sounds normal to you, the seal is not there — and most of the label rating is not either, however comfortable the fit feels.
When do I need plugs AND muffs together?
When the derated exposure still clears 85 dBA: doubling up typically adds roughly 5 dB over the higher-rated device, which is how the loudest industrial work is actually covered. Measure first — dual protection is a numbers decision, not a comfort one.
What size liner does my can take?
Width = half the can's circumference; length = height + bottom reach + 3-4" overhang. The free trash liner size calculator does it from your measurements and picks the standard size.
When is 3-mil actually necessary?
Edges and demolition weight — lumber, glass, metal, tear-off. Routine facility waste never needs it; 1.5-mil LLDPE or micron-gauge HD covers everything a custodial route produces.
Why did my liner fail at the seam?
Overfill past the rim, pooled liquid on a flat seal, or HD film asked to survive a puncture. The fix is density and overhang discipline, not blindly adding gauge.
Clear or black liners?
Policy, not performance: clear supports security screening, recycling audits, and sharps visibility; black conceals contents in public areas. Same duty at the same spec either way.
Star seal vs flat seal bottoms?
Star seals distribute liquid weight through a multi-point weld and conform to round cans — the commercial default. Flat seals suit dry waste and square cans; pooled liquid finds their corners.

Why trust WC Safety
WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.
Our methodology
Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
