LK® 7F0418 – 4×18 LLDPE Flat Bag | 1,000/CS

TUF-R® Standard LLDPE 4″ × 18″ Flat Bag for Full-Length Narrow Product Packaging

The LK® 7F0418 is a 4-inch by 18-inch flat bag manufactured from TUF-R® Standard LLDPE film at 1.0 mil thickness. At 18 inches, this long-format flat bag packages full-length narrow items in the 15–17 inch range with proper sealing clearance above. FDA-compliant material supports direct food contact. Sold 1,000 bags per case.

What Items Need a 4″ × 18″ Flat Bag?

Applications include full-length leeks, whole asparagus bundles, tall cut flowers and roses, extra-long baguettes, jumbo pretzel rods, wooden dowels, full-size rulers, curtain rod sections, medical device components, and long industrial parts. The 4-inch width keeps items aligned while the 18-inch length eliminates folding or trimming for full-length products.

Why Long-Format Flat Bags Require Higher-Performance Film

At 18 inches, a flat bag carries significantly more weight per unit than standard-length bags, and stress concentrates at the bottom seam and lower sidewalls when filled bags are stacked vertically. TUF-R® Standard LLDPE at 1.0 mil provides the dart impact strength and elongation-before-failure properties needed to maintain bag integrity throughout distribution. The film does not develop seal creep or stress whitening under the weight of full-length items, maintaining visual clarity through retail display.

How a 4″ × 18″ Flat Bag Packages Full-Length Products That Would Require Specialty Containers in Any Other Format

Full-length asparagus, single-stem roses, and long dowels would require custom-length bags or specialty packaging in most bag lines. The 7F0418 provides a standard-SKU solution for these items — available in case quantities from stock without custom runs or minimums. For operations packaging multiple full-length item types, one bag specification covers the range, reducing procurement complexity and inventory SKU count compared to sourcing specialty packaging for each item type.
