Check the resin code
A #2 or #4 mark, or a printed How2Recycle Store Drop-off label, is the clearest sign a bag belongs in the film bin rather than the trash.
Packaging
Are shipping bags recyclable?
Not in the curbside bin, most places. A poly mailer is thin flexible film, and film jams the machinery that sorts household recycling. The route that actually works is store drop-off, the same bin that takes plastic grocery bags, and only for the bags built as a single layer of plastic. Sources read 2026-08-19, cited below.

Film, not paper
A poly mailer recycles like a grocery bag, not like a cardboard box, and only through the right bin.
Curbside jams on it; store drop-off is built for it
“At MRFs, plastic wrapping can fly into the air and get stuck in the machinery, causing them to halt their lines.” Plastic Film Recycling, plasticfilmrecycling.org, read 2026-08-19
That is the whole reason a poly mailer does not belong in the same bin as the box it came in. Cardboard is rigid and sorts by weight and shape; a thin plastic bag flexes, catches wind inside the sorting building, and wraps around moving parts. The same source describes the program built for it instead: store drop-off, a retailer-sponsored collection that takes plastic bags and other flexible plastic packaging back through bins at the store itself.

Which bags the drop-off bin actually takes
Read 2026-08-19: Plastic Film Recycling's guidance is that flexible packaging marked with the #2 or #4 resin code can usually go through a store drop-off location, with a plain caution alongside — some flexible packaging is not accepted through these programs, so verify with the bin at the store before dropping off.
Feel it before you toss it
Single-layer films that feel and tear like a grocery bag are generally recyclable, while a mailer that is stiff, crinkly or coated is likely a laminate the program will not take.
Watch for a metallic sheen
A shiny or metallic-looking mailer is almost always a multi-layer laminate built for extra puncture resistance, and it goes in household trash rather than the film bin.
Both points are read 2026-08-19 from EcoPackables, a packaging supplier's own guide to identifying recyclable film, cited below alongside Plastic Film Recycling.
Before it goes in the bin
Empty anything that shipped inside the bag and give it a shake. A stray paper packing slip is a minor contaminant that most programs tolerate, but tape, bubble lining, or anything glued to the film should come off, and the bag itself needs to be clean and dry. A mailer that will not tear cleanly like a grocery bag is the surest sign it is a multi-layer build the drop-off bin was not designed for.

Common questions
Are shipping bags recyclable?
Not in a curbside bin. Plastic Film Recycling explains why: "At MRFs, plastic wrapping can fly into the air and get stuck in the machinery, causing them to halt their lines." A single-layer poly mailer usually can go through a store drop-off film program instead. Read 2026-08-19.
Where do you actually recycle a poly mailer?
At a store drop-off bin, the same one that takes grocery bags. Store drop-off is a retailer-sponsored program that collects plastic bags and other flexible plastic packaging through bins at the store, and packaging marked with the #2 or #4 resin code can usually go through it. Read 2026-08-19.
How do I tell if my mailer qualifies?
Feel and look at it. "Single-layer films that feel and tear like a grocery bag are generally recyclable," while a mailer that is "stiff, crinkly, or coated" or carries "a metallic sheen" is probably a multi-layer laminate that store drop-off programs will not take. A #2 or #4 resin code or a How2Recycle store-drop-off mark is the clearest signal. Read 2026-08-19.
Does the shipping label need to come off first?
Peel off what comes off easily and make sure the bag itself is clean and dry before it goes in the bin; a small paper label left behind is a minor contaminant, but tape, bubble lining or anything that keeps the bag from tearing cleanly should come off first.
What if the mailer is padded or bubble-lined?
That is a multi-layer construction, and store drop-off film programs are built around single-layer polyethylene. A padded mailer that will not tear clean like a grocery bag generally goes in household trash rather than the film bin unless the packaging itself states otherwise.
