LK® 8F0408 – 4×8 TUF-R® Heavy LLDPE Flat Bag, 1.8 Mil | 2,000/CS

LK® 8F0408 — 4×8 TUF-R® Heavy LLDPE Flat Bag, 1.8 Mil, 2,000/CS

The LK® 8F0408 is a 4-inch by 8-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 0.75–1.0 mil bags lack sufficient puncture resistance or tear strength. The open-top flat construction accepts heat sealing, impulse sealing, or twist-tie closure and fits standard wicket or tabletop bagging equipment.

When Should You Choose 1.8 Mil Over Standard LLDPE for a 4×8 Bag?

Step up to 1.8 mil when the contents have sharp edges, abrasive surfaces, or significant weight — or when film failures at the packing line are causing rework and rejects. The 4×8 footprint fills quickly with dense items like hardware kits, machined parts, or retail product samples where a standard-duty bag would stretch, puncture, or compromise seal integrity. TUF-R® Heavy LLDPE elongates before failing, absorbing impact stress rather than splitting, making it the correct specification for lines handling rigid or irregular components.

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

TUF-R® Heavy bags are produced from 100% linear low-density polyethylene (LLDPE) resin. At 1.8 mil, the film offers superior tensile strength, puncture resistance, and dart impact resistance compared to standard LLDPE. LLDPE’s molecular structure provides excellent elongation — the film stretches significantly before tearing, protecting contents during handling and transit. The film is optically clear for visual inspection, heat-sealable for airtight closure, and free of plasticizers, coatings, or barrier layers that would complicate recycling.

Pharmaceutical Sample and Blister Card Bagging in the 4×8 Format

The 4×8 dimension is a standard format in pharmaceutical sample packaging — blister cards, unit-dose packets, and promotional sample kits typically measure 3×6 to 4×8 and require over-packaging in a clear protective bag for distribution to clinicians, pharmacies, or trade show contacts. The 1.8 mil gauge provides sufficient rigidity to protect card edges from bending during transit while remaining thin enough for efficient heat sealing on automated bagging equipment. FDA-compliant LLDPE is appropriate for secondary packaging applications under 21 CFR guidelines for pharmaceutical and medical device packaging.

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, making it suitable for food packaging, food service, and any application requiring food-safe materials. The film is manufactured from 100% LLDPE with no coatings, colorants, or barrier layers, qualifying it as resin identification code #4 (LDPE) for recycling. Clean, dry bags are accepted at most retail plastic film drop-off locations for recycling into reclaimed LLDPE resin.
