What Makes LDPE Bags Different?
Low Density Polyethylene (LDPE) is the most commonly used plastic bag material because it offers the best combination of flexibility, clarity, and affordability. LDPE bags are softer and more flexible than LLDPE (Linear Low Density) or HDPE (High Density) bags, making them ideal for food packaging where product visibility and gentle handling matter.
LDPE vs LLDPE Side Gusset Bags:
| Feature | LDPE Side Gusset Bags | LLDPE (TUF-R®) Gusset Bags |
|---|
| Material Feel | ✅ Soft, flexible, gentle | Stiffer, more rigid |
| Clarity | ✅ Excellent (showcases products) | ✅ Excellent |
| Puncture Resistance | Good | ✅ Superior (per mil) |
| Best For | ✅ Food, bakery, retail | Industrial, heavy items |
| Cost | ✅ Lower per bag | Slightly higher |
| FDA Compliance | ✅ Yes (virgin resin) | ✅ Yes (virgin resin) |

Frequently Asked Questions
What is a side gusset bag?A side gusset bag is a poly bag with creased, expandable pleats on both sides that open out when the bag is filled, so it holds bulky items a flat bag of the same width cannot. LK Packaging LDPE side gusset bags are made from seamless tubing with a sealed bottom and are stocked in 1.0, 1.5, 2.0 and 3.0 mil gauges. Are LK Packaging LDPE side gusset bags food safe?Yes. LK Packaging LDPE side gusset bags are made from 100% virgin polyethylene resin and meet FDA requirements for direct food contact, so they are used for bakery goods, produce, bulk snacks and other food service applications. What does "seamless tubing" mean on a poly bag?Seamless tubing means the bag is extruded as one continuous tube of polyethylene and sealed only at the bottom, with no side seals. Side seals are the weakest point on many bags, so seamless construction reduces the risk of splitting or tearing. Why do bags 15 inches wide and under come in dispenser packs?LK Packaging packs bags 15" wide and under in 100-count dispenser packs so a worker can pull one bag at a time without contaminating the rest, which keeps the bags clean and reduces waste. Cases and inner packs are bar coded and clearly labeled for easy identification. Can you heat seal LDPE side gusset bags?Yes. LDPE side gusset bags seal cleanly with an impulse sealer or other heat sealer, which gives a tamper-evident closure for food. They can also be closed with twist ties, tape or staples for non-food items. What is the difference between LK Packaging and Elkay Plastics?They are the same company. Elkay Plastics rebranded as LK Packaging, and the product quality and specifications remain identical. Which mil thickness should I choose for gusseted bags?Match the gauge to product weight: 1.0 mil for lightweight items such as clothing, textiles and baked goods; 1.5 mil for standard bakery and retail use; 2.0 mil for heavier produce and bulk items in the 5-10 lb range; and 3.0 mil for industrial parts and heavy food items. For sharp or very heavy contents, step up to LLDPE TUF-R® gusset bags instead. What is the difference between LDPE and LLDPE (TUF-R®) gusset bags?LDPE gusset bags are softer, more flexible and very clear, which makes them the usual choice for food, bakery and retail packaging. LLDPE TUF-R® gusset bags are stiffer and offer more puncture resistance per mil, so they suit industrial and heavier loads. Both are made from virgin resin and meet FDA requirements for food contact. Request samples to test before bulk ordering.
