LK® 7F1221 – 12×21 LLDPE Flat Bag | 1,000/CS

LK® 7F1221 — 12×21 Inch Clear LLDPE Flat Poly Bag, 1,000 Per Case

The LK® 7F1221 is a 12-inch by 21-inch flat poly bag made from 1.0 mil TUF-R® Standard LLDPE film. Sold 1,000 units per case, this non-standard dimension addresses fill lengths that exceed the 20-inch size but do not require a full 24-inch bag. The extra inch of clearance provides the sealing headroom operators need when running these bags on tabletop heat sealers.

When Is a 12×21 Flat Bag the Right Choice?

The 12×21 format suits products whose fill length runs 17 to 19 inches, requiring roughly 2 inches of bag above the product for a clean seal. Garment packagers use this size for extra-long dress shirts and untucked fashion tops that spill past 20-inch bags. Food distributors bag long French baguettes and specialty bread loaves that benefit from the additional headroom. The 21-inch length also accommodates standard 18×12 architectural prints with room for a top fold seal.

1.0 Mil TUF-R® LLDPE: Film Specs That Matter in Production

TUF-R® Standard LLDPE at 1.0 mil is formulated for sealing consistency. The resin’s narrow melt-flow window means heat-seal dwell times remain predictable across production runs, reducing seal failures caused by gauge variance. Slip and anti-block additives in the film formulation allow individual bags to open cleanly from the case without static clinging or sticking at the mouth.

12×21 Bags for Gym Apparel Sets, Long Art Tubes, and Promotional Posters

Athletic apparel brands use the 21-inch length to accommodate track pants, leggings, and long-sleeve base layers packaged as folded sets. Print and promotions distributors slip rolled or flat 12×21 promotional posters into these bags for client delivery — an alternative to mailing tubes that keeps large-quantity shipments flat. Sign and banner producers use this bag to individually protect 12-inch-wide banner panels before stacking them for bulk shipping.
