Minigrip® Reclosable Poly Bags
The Red Line reclosable bag that became an industrial purchasing standard. Press-to-close, one-hand open, built to a construction spec that hasn't needed to change in 50+ years. Stocked in 2 to 6 mil LDPE, FDA and USDA compliant, shipping the same day on orders placed by 4PM EST.
Shop Minigrip® reclosable bags by thickness
Clear Red Line bags and white block, both by the gauge. Match the mil to your contents: lighter for retail and parts, heavier for sharp or industrial items.
Specialty reclosable styles
Distinct reclosable products for specific jobs: a slider closure, food storage, static protection, and material options. Each is its own line, not a gauge of the Red Line bag above.
What is the Minigrip® Red Line?
The red strip on the bag lip isn't decoration. It marks a genuine Minigrip® bag built to a defined construction standard, one that's stayed consistent long enough that buyers began calling it out by name on purchase orders. That's how Red Line became a spec item in industrial and institutional purchasing.
Red Line quality identifier
The red strip confirms a genuine Minigrip® bag, consistent bag after bag.
Ultrasonic-welded waffle seal
The zipper track is ultrasonically welded, not glued, so it resists delaminating under pressure or repeated use.
Reinforced side seams
Seams hold up to opening and filling without splitting, which matters in high-throughput lines.
One-hand open and close
Snaps open and shut reliably, single-handed, even with gloves on.
Minigrip® or ClearZip®, which do you need?
Both are reclosable LDPE zipper bags. The difference is brand recognition, construction, and price. Buy Minigrip® when your spec calls for it by name. Buy our own ClearZip® value brand when you want the same protection at a lower price.

Common questions about Minigrip® reclosable bags
Red Line construction: an ultrasonic-welded waffle seal, reinforced side seams, and a one-hand open-and-close zipper that holds up to repeated use. The red strip on the lip marks a genuine Minigrip® bag. That consistency is why it became a named specification in industrial purchasing over 50 years ago.
Both are reclosable LDPE zipper bags. Minigrip® is the named-brand spec with Red Line construction and recognized equity in industrial supply chains, worth the premium when a spec calls for it. ClearZip® is our own line at a lower factory-direct price, the better value when brand isn't specified.
Reclosable means the bag has a built-in closure you open and close by hand, like a zipper, again and again. Resealable is often used for adhesive or heat-seal closures that reclose once. Minigrip® bags are reclosable: the zipper reseals as many times as you need.
Yes. Minigrip® Red Line bags are made from LDPE and meet FDA and USDA specifications for food contact. Tell us the application and we'll confirm the right bag for it.
The zipper is leak-resistant for solids and most contents, but a press-to-close bag isn't guaranteed liquid-tight under pressure. For liquids, ask a packaging expert about leak-proof options.
