LK® 8F1218 – 12×18 TUF-R® Heavy LLDPE Flat Bag, 2 Mil | 500/CS

LK® 8F1218 — 12×18 TUF-R® Heavy LLDPE Flat Bag, 2 Mil, 500/CS

The LK® 8F1218 is a 12-inch by 18-inch heavy-gauge LLDPE flat bag made from 2 mil TUF-R® Heavy film, packed 500 per case. TUF-R® Heavy is LK Packaging’s heavy-duty LLDPE line, and at 12×18 this bag is one of the larger formats in the flat bag range — appropriate for oversized industrial components, large food items, garments, and sheet media. The flat open-top construction accepts heat sealing, impulse sealing, or twist-tie closure for both manual and automated applications.

When Should You Choose 2 Mil Over Standard LLDPE for a 12×18 Bag?

The 12×18 format is typically used for content with both significant face area and meaningful weight or edge risk. Standard-duty film in this size provides limited resistance to puncture from rigid corners or hardware embedded in soft goods, and the large face area means any localized stress travels farther before the film can distribute it. The 2 mil gauge addresses this by providing substantially greater resistance per unit area. Use 2 mil when filling with auto parts, tool assemblies, large garments with hardware (zippers, rivets), produce bundles over 3 pounds, or oversized retail merchandise requiring a premium-feel poly bag.

TUF-R® Heavy LLDPE Film Properties — 2 Mil Gauge

TUF-R® Heavy 2 mil bags are extruded from 100% LLDPE at 2.0 mil nominal gauge. The film provides high puncture resistance and dart impact strength across the full 12×18 surface area. LLDPE’s elongation characteristics allow the film to stretch and distribute impact stress before failure rather than tearing at the point of contact. The material is optically clear for full content inspection, consistently heat-sealable across the wide seal zone, and free of coatings, barrier layers, or plasticizers.

Framed Art Print and Picture Frame Protective Bagging in the 12×18 Format

The 12×18 flat bag is a standard format in the art print and picture framing industry for protective bagging of 11×14 and 12×16 framed pieces before shipment or retail display. Frame hardware — hanging wire, D-rings, and corner reinforcements — creates multiple hard-point contacts against the bag interior that can puncture standard-duty poly during transit. The 2 mil TUF-R® Heavy gauge resists these contact points without failing, keeping the frame surface protected from scratches, moisture, and handling damage through the distribution channel. The film’s optical clarity provides full visual display of the framed artwork on the gallery or retail floor without requiring the protective bag to be removed from standard display pieces.
