Why Choose 4 Mil Poly Tubing?

At 4 mils thick, this low density polyethylene tubing strikes the perfect balance between durability and cost-efficiency. It's thick enough to protect products during shipping and storage, yet economical enough for high-volume packaging operations.

Common Applications for 4 Mil LDPE Tubing

  • Food Packaging: Bakery items, produce, frozen goods, bulk foods
  • Industrial Parts: Metal components, hardware, automotive parts
  • Retail Products: Toys, textiles, sporting goods, craft supplies
  • Long Items: Curtain rods, lumber, pipes, rolled materials

How to Use Poly Tubing

Using poly tubing is simple:

  1. Measure your product and add 3-4 inches for sealing
  2. Cut the tubing to your desired length
  3. Insert your product
  4. Heat seal, tape, or staple both ends closed

Sealing Options

Heat Sealing: Use an impulse sealer or heat gun for a professional, tamper-evident seal. Perfect for food products and high-volume operations.

Tape or Staples: Quick closure method ideal for non-food items and lower-volume operations.

Frequently Asked Questions

What is 4 mil low density poly tubing?

4 mil low density poly tubing is a continuous plastic sleeve, open at both ends, made from 100% virgin low density polyethylene (LDPE) at 4 mils thick (0.004"). You cut it to whatever length your product needs, then seal one or both ends, so a single roll replaces dozens of stock bag sizes. It ships on 12" diameter rolls with 3" cores.

Is 4 mil poly tubing food safe?

Yes. Our 4 mil poly tubing is made from 100% virgin LDPE with no recycled content and meets FDA requirements for direct food contact, so it can be used for bakery items, produce, frozen goods and bulk foods. The film is also recyclable as LDPE (resin code #4) where your local facility accepts it.

What is the difference between 2 mil, 4 mil, and 6 mil poly tubing?

The mil rating is film thickness, and thicker film means more puncture and tear resistance at a higher cost per foot. 4 mil is the medium-duty middle ground that suits most food, retail and light industrial packaging. For lighter-weight items see our 2 mil poly tubing; for sharp or heavy parts see our 6 mil poly tubing.

How do you seal poly tubing?

Measure your product, add 3 to 4 inches for the seals, cut the tubing to that length, insert the product, then close both ends. An impulse sealer or heat gun gives a professional, tamper-evident seal and is the right choice for food products and high-volume runs; tape or staples work fine for non-food items and lower volumes.

Can you print on 4 mil poly tubing?

Yes. One side of the film is surface-treated to accept printing inks, so it can be custom printed with your logo, product information or handling instructions. Contact Prism Pak for custom printing options and minimums.

What widths and roll sizes does 4 mil poly tubing come in?

We stock a wide range of lay-flat widths so you can match the tubing to your product's dimensions, all supplied on 12" diameter rolls with 3" cores. Browse the stock widths above, or contact us if you need a custom width or a different roll length.
