LK® 8F0507 – 5×7 TUF-R® Heavy LLDPE Flat Bag, 1.8 Mil | 2,000/CS

LK® 8F0507 — 5×7 TUF-R® Heavy LLDPE Flat Bag, 1.8 Mil, 2,000/CS

The LK® 8F0507 is a 5-inch by 7-inch heavy-gauge LLDPE flat bag made from 1.8 mil TUF-R® Heavy film, packed 2,000 per case. TUF-R® Heavy is LK Packaging’s heavy-duty LLDPE line engineered for applications where standard-duty film is insufficient. The open-top flat construction is compatible with heat sealing, impulse sealing, or self-sealing closures and handles both manual and automated bagging operations.

When Should You Choose 1.8 Mil Over Standard LLDPE for a 5×7 Bag?

Use 1.8 mil TUF-R® Heavy when the 5×7 format carries items with any combination of sharp edges, meaningful weight, or surface abrasion. Components like metal stampings, ceramic tiles, or hardened plastic parts that would notch or puncture standard film are ideal candidates. Heavy-gauge film also extends effective shelf life for products that remain in the bag during storage, reducing film fatigue from repeated handling. Where customer perception of quality matters — such as retail or e-commerce packaging — the heavier gauge communicates a premium product standard.

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

TUF-R® Heavy bags are extruded from 100% linear low-density polyethylene (LLDPE). At 1.8 mil, the film delivers high puncture resistance, superior dart impact strength, and excellent elongation-to-break. LLDPE’s flexible molecular backbone allows the film to stretch and conform under load rather than crack or split, protecting contents from impact damage. The film is optically clear for full visual inspection, heat-sealable to an airtight seam, and free of coatings, plasticizers, or barrier layers.

Greeting Card, Photo Print, and Stationery Bagging in the 5×7 Format

The 5×7 dimension is the industry-standard format for greeting cards, photo prints, and art prints. Card and stationery publishers, photo labs, and independent sellers routinely bag 5×7 product in individual poly bags for moisture protection during shipping and retail display. The 1.8 mil gauge provides a stiffer, more premium feel than standard-duty bags, reducing the tendency for bags to collapse around flat media and improving presentation at point of sale. The film’s clarity shows the artwork at full quality, and heat-sealed edges eliminate any risk of moisture ingress in humid shipping environments.
