Why Choose LK Packaging 1 Mil Low Density Flat Bags?
Low density polyethylene (LDPE) flat bags offer the ideal balance of flexibility, strength, and cost-effectiveness for a wide range of packaging applications. LK Packaging's 1 mil bags are manufactured using seamless tubing technology, which creates bags that are significantly stronger than traditional side-sealed alternatives.
Seamless Tubing Construction: The LK Packaging Difference
Unlike standard plastic bags with heat-sealed sides, LK Packaging bags are formed from continuous polyethylene tubing. This manufacturing process eliminates the weak points created by side seals, which are often the first areas to fail under stress. The result? Bags that can handle heavier loads and resist tearing even when filled to capacity.
FDA-Approved for Food Contact Applications
Food safety is paramount in packaging. All LK Packaging 1 mil low density flat bags are manufactured from virgin LDPE resin that meets FDA 21 CFR 177.1520 standards for direct food contact. These bags are ideal for:
- Bakery items - Bread, pastries, cookies, and baked goods
- Produce - Fruits, vegetables, and fresh herbs
- Dry goods - Grains, nuts, candy, and bulk foods
- Frozen foods - Ice, frozen fruits, and pre-packaged meals
What Does "1 Mil" Mean?
Bag thickness is measured in mils, where 1 mil equals 0.001 inches (or 25.4 microns). A 1 mil bag provides excellent protection for lightweight items while remaining economical. For heavier or sharp-edged products, consider our 2 mil or 3 mil low density bags for added durability.
Common Applications & Use Cases
Retail & E-commerce: Protect products during shipping and display. Clear bags showcase contents while keeping items dust-free and clean.
Food Service: Package bulk ingredients, pre-portioned items, or takeout orders. FDA approval ensures safety for direct food contact.
Manufacturing & Industrial: Organize small parts, protect components from contamination, and streamline inventory management.
Healthcare & Labs: Store medical supplies, protect sensitive equipment, and maintain sterile environments.
Choosing the Right Size
LK Packaging 1 mil flat bags are available in a wide range of dimensions. When selecting a bag size, consider:
- Product dimensions - Allow 1-2 inches of clearance on all sides
- Fill weight - 1 mil bags typically handle up to 2-3 pounds
- Closure method - Leave extra length if using twist ties or heat sealing
Storage & Handling Best Practices
To maintain optimal bag performance, store bags in a cool, dry location away from direct sunlight. LDPE can degrade with prolonged UV exposure, so indoor storage is recommended. Keep bags sealed in their original packaging until ready to use to prevent dust accumulation.

1 Mil Low Density Flat Bags: Frequently Asked Questions
What does 1 mil mean on a poly bag?
One mil equals 0.001 inches, or 25.4 microns, of wall thickness. A 1 mil low density polyethylene flat bag is a light-duty gauge — thick enough to protect and contain lightweight items, and the most economical LDPE thickness we stock. Step up to 2, 3, 4 or 6 mil for heavier or sharp-edged products.
Are 1 mil low density flat bags food safe?
Yes. LK Packaging 1 mil low density flat bags are made from virgin LDPE resin that meets FDA 21 CFR 177.1520 for direct food contact. They are used every day for bread and bakery items, produce, nuts, candy and bulk dry goods, and frozen foods.
How much weight can a 1 mil flat poly bag hold?
A 1 mil LDPE flat bag typically handles up to 2 to 3 pounds. For heavier loads, sharp or angular parts, or bags that will be handled repeatedly, move up to a 2 mil, 3 mil, 4 mil or 6 mil low density flat bag.
What is the difference between seamless tubing bags and side-sealed bags?
Seamless tubing bags are formed from one continuous extruded polyethylene tube, so the sides of the bag are solid film with no seal. Side-sealed bags are heat-sealed along both edges, and those seals are usually the first place a bag fails under load. LK Packaging 1 mil flat bags use seamless tubing construction, which is why they resist tearing better than side-sealed bags of the same gauge.
What size flat poly bag should I order?
Measure your product and allow 1 to 2 inches of clearance on all sides, then add extra length at the top for your closure method — twist tie, tape, or heat seal. Flat bag sizes are listed width by length, and the width is the flat, unopened measurement across the bag.
How should poly bags be stored?
Store LDPE bags indoors in a cool, dry place out of direct sunlight, because prolonged UV exposure degrades polyethylene. Leave cases sealed in their original packaging until you need them so dust does not settle on the film.
Who uses 1 mil low density flat bags?
Bakeries, produce departments and food service kitchens use them for FDA-compliant food packaging. Retail and e-commerce sellers use them to keep products clean and dust-free in shipping. Manufacturers use them to bag and organize small parts, and healthcare and laboratory operations use them to store supplies and protect equipment.
