LK® 8F0608 – 6×8 TUF-R® Heavy LLDPE Flat Bag, 1.8 Mil | 1,000/CS

LK® 8F0608 — 6×8 TUF-R® Heavy LLDPE Flat Bag, 1.8 Mil, 1,000/CS

The LK® 8F0608 is a 6-inch by 8-inch heavy-gauge LLDPE flat bag made from 1.8 mil TUF-R® Heavy film, packed 1,000 per case. TUF-R® Heavy is LK Packaging’s heavy-duty LLDPE line, designed for applications where standard-duty film thickness is insufficient for the product or process. The open-top flat format accepts heat sealing, impulse sealing, or fold-and-seal closure and runs on standard tabletop and automated bagging equipment.

When Should You Choose 1.8 Mil Over Standard LLDPE for a 6×8 Bag?

For the 6×8 format, the transition to 1.8 mil TUF-R® Heavy is warranted when fill weight exceeds approximately one pound, when contents have irregular geometry that concentrates stress on specific points of the bag, or when the packed product will experience thermal cycling between frozen and ambient temperatures. Freezer-grade applications benefit significantly from heavy-gauge LLDPE: standard-duty film becomes brittle at sub-zero temperatures and may crack or split, while 1.8 mil TUF-R® Heavy retains its flexibility and elongation characteristics across a broad temperature range.

TUF-R® Heavy LLDPE Film Properties — 1.8 Mil Gauge

TUF-R® Heavy bags are extruded from 100% LLDPE resin at 1.8 mil nominal gauge. The film provides high puncture resistance, strong dart impact resistance, and outstanding elongation-to-break — allowing the bag to stretch and absorb stress rather than crack under load. The film is optically clear for visual inspection of contents, heat-sealable to a consistent airtight seam, and free of coatings, plasticizers, or barrier additives. LLDPE maintains flexibility at freezer temperatures, making TUF-R® Heavy an appropriate specification for frozen and refrigerated food applications.

Frozen Food Portioning and Meal Prep Packaging in the 6×8 Format

The 6×8 flat bag is a widely used format in frozen food portioning, meal prep operations, and catering commissaries. Individual protein portions — chicken breasts, fish fillets, beef medallions — and portioned vegetable mixes fit the 6×8 footprint at typical meal-prep sizes. The 1.8 mil TUF-R® Heavy gauge addresses two specific failure modes common with standard-duty bags in frozen applications: seal failure at the jaw-sealer when film chills rapidly, and bag splitting during stacking and transport of frozen product. FDA-compliant LLDPE is appropriate for direct contact with raw and cooked food products, and the film seals cleanly on commercial impulse and continuous band sealers at standard settings.

FDA Compliance and Recyclability of TUF-R® Heavy LLDPE Flat Bags

TUF-R® Heavy LLDPE film is FDA-compliant under 21 CFR for direct food contact, covering fresh, frozen, and cooked food packaging applications. The film’s 100% LLDPE single-resin composition carries resin identification code #4 (LDPE) and qualifies for recycling at retail plastic film drop-off programs when clean and dry. No coatings, dyes, or barrier layers are incorporated into the film formulation.
