Who makes Kirkland Signature Flex-Tech Kitchen Trash Bags, 13 Gallon, 200 ct?
No reliable public evidence identifies the manufacturer of Kirkland Signature Flex-Tech Kitchen Trash Bags, 13 Gallon, 200 ct as of August 10, 2026.
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.
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.
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.
