TUF-R® vs. Standard LDPE Bags: What's the Difference?
Not all poly bags are created equal. Here's why TUF-R® Linear Low Density bags outperform traditional Low Density bags:
Advanced Resin Technology
TUF-R® bags use a proprietary LLDPE resin blend that delivers 3x the puncture resistance of standard LDPE at the same gauge. This means a 2.75 mil TUF-R® bag performs like a 0.9-1.25 mil LDPE bag—but costs 30-40% less per unit.
Bottom-Sealed for Maximum Strength
Unlike side-sealed bags that split under stress, TUF-R® bags feature heat-sealed bottom seams for superior load distribution. Perfect for heavy items like:
- Metal fasteners and hardware
- Food products (nuts, grains, candies)
- Janitorial supplies and chemicals
- Textiles and apparel
- Medical devices and components
Crystal-Clear Visibility
TUF-R® bags offer exceptional clarity—no cloudiness or haze. Ideal for retail display, quality inspection, and inventory management. Your products look better, and you can identify contents at a glance.
Frequently Asked Questions
What does 2.75 mil mean on a poly bag?2.75 mil means the bag wall is 0.00275 inch thick, since 1 mil equals 0.001 inch. Because TUF-R® bags are made from linear low density polyethylene (LLDPE) rather than standard LDPE, a 2.75 mil TUF-R® bag carries loads that would normally require a noticeably heavier-gauge LDPE bag. Are 2.75 mil TUF-R® flat bags food safe?Yes. All TUF-R® bags meet FDA standards for direct food contact, so they can be used for dry goods, produce, bakery items, candy, nuts, and grains. They are not recommended for hot foods or liquids without proper testing for your application. What is the difference between TUF-R® LLDPE bags and standard LDPE poly bags?TUF-R® bags use an LLDPE resin that provides higher tensile and puncture resistance than LDPE at the same thickness, so a lighter TUF-R® bag replaces a heavier LDPE bag. TUF-R® bags are also bottom-sealed rather than side-sealed, which distributes weight across the seam instead of concentrating stress on the sides. What sizes do 2.75 mil TUF-R® flat bags come in?We stock 2.75 mil TUF-R® flat bags from small 4" x 6" sizes up to large industrial sizes around 24" x 36". Every bag 15" wide and under ships in 100-bag inner packs with barcode labels, which makes inventory counts and reorders easier. How much can I save switching from LDPE bags to TUF-R®?Customers typically save 30-40% by switching from heavier-gauge LDPE to TUF-R®, because a 2.75 mil TUF-R® bag replaces a 1.0-1.25 mil LDPE bag. You use less plastic per bag, which lowers both material cost and disposal volume. Can 2.75 mil TUF-R® bags be custom printed?Stock TUF-R® bags are sold unprinted, but Prism Pak does run custom printed poly bags for branded packaging. Minimum order quantities apply — call 570-709-0366 for print pricing and lead times. Industries Using TUF-R® Heavy Duty Bags
