1.5 Mil vs 2 Mil vs 3 Mil: Which Thickness Do You Need?
1.5 mil bags are best for items under 5 lbs that need moisture protection but not heavy-duty strength. Match the gauge to the weight and edges of what you are packing:
- Light items (under 5 lbs): 1.5 mil is the cost-effective choice
- Medium items (5-10 lbs): Step up to 2 mil
- Heavy items (10+ lbs) or sharp edges: Use 3 mil, 4 mil, or 6 mil

Frequently Asked Questions
Are 1.5 mil LDPE flat bags food safe?Yes. All LK Packaging 1.5 mil low density polyethylene flat bags are FDA compliant under 21 CFR 177.1520 for direct food contact, and they are made from virgin resin with no recycled content. They are used every day for baked goods, candy, produce, and other dry foods. How thick is a 1.5 mil bag, and how much weight will it hold?A 1.5 mil bag is 0.0015 inches thick, or one and a half thousandths of an inch, held to a plus or minus 10% gauge tolerance. It is rated for light-duty use, generally items under 5 pounds with no sharp corners; for 5 to 10 pounds move up to 2 mil, and for 10 pounds or more or anything with edges that can puncture, use 3 mil or heavier. What is the difference between LDPE and HDPE bags?LDPE (low density polyethylene) bags are softer, more flexible, and crystal clear, so they are the right pick when the customer needs to see the product.
