METRONIC 30-33 Gallon Can Liners Review

Affiliate disclosure: WC Safety earns a commission on qualifying Amazon purchases at no extra cost to you.

The economy-LD class from our gauge decode, in the flesh: 0.6-mil liners for light mixed waste in mid-size cans — 250 for the listed price or 14 cents per liner on cans that never see weight. Buying gauge you don't need is the most common liner overspend; this is the case that stops it.

Editorial rating: 4.3/5. The right cheap liner for genuinely light duty; the decode chart tells you which cans qualify.

Who it's for

Low-fill office and retail cans, lobby waste, light break-room duty — the receptacles that fill with volume, not mass.

Skip it if

Kitchens and collection points: 0.6 mil on wet, dense waste is a blowout schedule. Match the gauge to the load or pay in mopping.

How it fits the facility safety program

Waste containment is exposure control: right-density, right-size liners keep sharps and liquids inside the bag. Density to waste stream, size from the can's math — the calculator does the arithmetic. New to the department? Start at the janitorial & facility safety collection overview.

How it compares

vs 1.6-mil 33-gal: the same size at working gauge. (Our take: full 1.6-mil 33-gal review.)

vs Aluf HD: the HDPE philosophy at smaller size. (Our take: full Aluf HD review.)

Pros and cons

Pros

• 14¢/liner at case rate
• 250-count case
• Fills the economy row of the gauge chart

Cons

• Genuinely light-duty — respect the gauge
• Import brand consistency check on case one
• Wrong anywhere liquids concentrate

Build out the facility program

One product is a purchase; the program is what protects people. Decision tools: the dispenser compatibility guide, the trash liner size calculator, and the mil & micron decode. Ranked picks: paper towels, liners, wet floor signs, vacuums, carts, entrance mats, and eyewash stations. The safety context is the custodial worker safety hub with the chemical safety and floor stripping guides; crews run nitrile gloves, splash goggles, and slip-resistant footwear. Shop the department: janitorial & facility safety and its collections — equipment, liners, restroom, matting, eyewash — with case orders via bulk & business orders.

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.

Common questions

How does this Wave-4 gear fit the existing department?

It's the gap fill: mops for the buckets we already sold, receptacles for the liner program, JRT hardware for the tissue cases, cone signs for the doors A-frames can't hold, and the liner sizes the decode chart listed but the store didn't stock.

What do mil and micron ratings actually mean?

Mil is thousandths of an inch on low-density (LLDPE) bags; micron is thousandths of a millimeter on high-density (HDPE) film. Different materials, different failure modes — our decode guide has the full charts.

How do I pick the right gauge?

Density to waste stream first (LLDPE for mixed and edged waste, HDPE for light dry), then gauge to weight: 0.6-mil for light fill, 1.1-1.6 for working duty, 2+ mil for heavy loads, 3-mil for debris. Overspending on gauge is the most common liner mistake.

Why do rectangular cans need special liners?

Geometry: round-cut bags on Slim Jim rectangles bunch in corners and shortchange overhang — the fit failure that dumps bags into cans. Rectangle-cut liners match the perimeter and hang correctly.

What size liner fits my can?

Width = half the can's circumference; length = height + bottom reach + 3-4 inches of overhang. The free liner size calculator does the math and names the standard size to order.

Why does overhang matter so much?

The 3-4 inches folded over the rim is what carries the load — bags gripped only by friction slide in as they fill. Right-size liners with real overhang are the difference between a bag pull and an excavation.

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.
