The common claim vs. the evidence

The common claim

What most answers say — and what the evidence supports

The prevailing answer is Reynolds - owner of the Hefty brand and, through its Reynolds Presto Products subsidiary, a major store-brand bag co-packer - and Costco's own website groups part of its trash-bag assortment under a 'REYNOLDS CONSUMER PROD CO' manufacturer filter. But that filter could not be tied to the specific Kirkland Signature Flex-Tech line through the archive (Costco blocks automated access and no snapshot of the Kirkland bag's product page exists), and it conflicts with a second signal: 'Flex-Tech,' the sub-brand printed on the Kirkland bags, is a trademark registered for trash bags to Poly-America, L.P., a large Texas bag manufacturer whose products use the same 'flex' and gripping-drawstring technology. No route reliably resolves which company makes the Kirkland bags, so no manufacturer is asserted here.

The honest part

Evidence & sources

Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below is the documented search — every database and record we checked, and what each one returned.

What we checked — 7 databases & records on August 10, 2026
Costco manufacturername (mfName) facet (costco.com/trash-bags.html; costco.com blocks automated fetch) July 5, 2026

Costco's trash-bags category exposes a manufacturer filter that includes 'REYNOLDS CONSUMER PROD CO' (live URL: costco.com/trash-bags.html?manufacturername=reynolds-consumer-prod-co). But that facet spans Costco's whole trash-bag assortment - which also includes branded Hefty bags (a Reynolds brand) - and could NOT be tied to the specific Kirkland Signature Flex-Tech line: costco.com blocks bots and no Wayback snapshot of the Kirkland Flex-Tech product page (item 100342484 / 100488871) exists to read its per-item mfName. Route inconclusive for this SKU.

USPTO trademark route (TSDR / Trademarkia for the on-package 'Flex-Tech' mark) July 5, 2026

'Flex-Tech,' the sub-brand printed on the Kirkland bags, is a registered U.S. trademark for 'trash bags' (serial 87146443, reg. 5188538) reported to be owned by Poly-America, L.P. of Grand Prairie, TX - a large domestic bag manufacturer whose products feature the same 'patented flex technology' and gripping drawstrings as the Kirkland line. This points to Poly-America, NOT Reynolds, and directly conflicts with the Costco mfName facet. Could not archive-verify the USPTO/Trademarkia record (TSDR is JS-only; trademarkia.com and uspto.report return 403 to automation), so the ownership is a secondary-index assertion, not a verified primary record - upgrade path: confirm the TSDR owner block from Ian's browser.

CPSC recall database (SaferProducts.gov REST API) July 5, 2026

Zero recalls for 'trash bag' or 'garbage bag'; the 2 'Kirkland' recalls on file (Valdobbiadene Prosecco bottles; six-quart saute pans) are unrelated to bags. No co-packer surfaced via the recall route.

ImportYeti / U.S. customs bills of lading July 5, 2026

Route is structurally inapplicable here: both candidate makers (Reynolds and Poly-America) are domestic U.S. manufacturers, and U.S.-sold Kirkland trash bags are produced domestically, so import bills of lading would not capture the maker - absence of records proves nothing (tier-5 caveat, same as the paper-goods records).

News and executive-statement sweep (Google/Bing news, trade press, Hunker, The Kitchn) July 5, 2026

No executive statement or investigative report names the maker of Kirkland trash bags. Reporting repeats 'Reynolds/Hefty' without evidence; the closest documented analog is Hunker's finding that Reynolds Presto Products makes Walmart's Great Value bags (tied by Reynolds-owned trademarks such as 'Stand 'N Store' and co-defendant lawsuits) - but that is Walmart, not Costco, and no equivalent Kirkland-specific documentation exists.

Costco help/FAQ and disclosure pages (via Wayback; costco.com blocks automated fetch) July 5, 2026

No Costco page names the trash-bag supplier. Costco's chemical-disclosure/SDS route (which names manufacturers for Kirkland detergents and dish soap) does not exist for plastic/paper goods, so that avenue is unavailable for trash bags, mirroring the paper-towels finding.

Community/rumor scan (Reddit r/Costco, content-mill listicles) July 5, 2026

Claims are contradictory and evidence-free: Reynolds/Hefty is the most repeated name, while the 'Flex-Tech' trademark implicates Poly-America. No consistent, verifiable single maker emerges.

Frequently asked

Who makes Kirkland Signature trash bags?
No reliable public evidence identifies the manufacturer. Two signals point in different directions and neither could be verified through the archive: Costco's website filters part of its trash-bag range under a 'Reynolds Consumer Prod Co' manufacturer facet (Reynolds owns Hefty and the Presto Products store-brand bag business), while the 'Flex-Tech' sub-brand on the Kirkland bags is a U.S. trademark registered for trash bags to Poly-America, a large Texas manufacturer. Costco does not disclose the supplier, and no recall, court record, or executive statement names it.
Are Kirkland Flex-Tech trash bags the same as Hefty?
That is not publicly documented. Hefty is a Reynolds brand, and Reynolds is the most commonly repeated guess for Kirkland's bags, but the claim is unverified - and the 'Flex-Tech' name on the Kirkland bags is actually a Poly-America trademark, a different manufacturer entirely. No public source establishes that Kirkland bags and Hefty bags share a maker.
Did the maker of Kirkland trash bags change?
No manufacturer change is publicly documented, because no manufacturer was ever reliably documented in the first place. The two candidate companies - Reynolds and Poly-America - are both domestic U.S. bag makers, which is also why import records are no help: U.S.-sold trash bags are produced domestically, so customs data would not capture the maker.
