This 4″ × 8″ LLDPE flat poly bag is a dependable choice for packaging, storing, and protecting parts, products, and supplies.
TUF-R® Standard LLDPE 4″ × 8″ Flat Bag for Elongated Item and Food Packaging
The LK® 7F0408 is a 4-inch by 8-inch flat bag made from TUF-R® Standard LLDPE film at 1.0 mil thickness. The 2:1 length-to-width ratio makes this format ideal for elongated items that need a 4-inch opening with room to extend, covering a broad range of food, retail, and industrial packaging applications. FDA-compliant material supports direct food contact. Sold 1,000 bags per case.
What Items Are Typically Packaged in a 4″ × 8″ Flat Bag?
Common applications include granola bars, pretzel rods, string cheese, licorice sticks, candy bars, long snack items, markers, paint brushes, small hardware kits, craft supply bundles, and multi-part retail kits. The 4-inch width keeps narrow elongated items positioned without folding or bridging at the bag bottom.
Why 1.0 Mil LLDPE Is the Right Specification for 4-Inch Flat Bag Formats
TUF-R® Standard LLDPE at 1.0 mil provides the strength-to-weight ratio that 4-inch flat bag formats require. The heavier gauge compared to 0.9 mil adds marginal material cost but meaningfully improves puncture resistance at item corners and edges — relevant for hardware kits, marker sets, and other items with protrusions that can stress thinner films. Clarity and seal performance remain consistent across manual and semi-automated sealing equipment.
How a 4″ Opening With 8″ of Depth Balances Loading Ease and Bag Efficiency for Medium-Profile Elongated Items
The 4 × 8 dimension is sized to avoid two common failure modes: bags too short to seal cleanly above the item, and bags with excess depth that adds material cost and creates loose packaging. A 6-inch item fills approximately 75% of the bag depth, leaving 2 inches of consistent headspace for heat sealing. This proportion supports clean, repeatable seals across manual and semi-automated packaging lines without oversizing the bag.
