Layflat Tubing

Lay flat poly tubing is flexible thin plastic tubing pressed flat then wound on rolls. Lay flat tubing is synonymous with layflat tubing or lay-flat tubing. Brentwood Plastics makes lay flat tubing available as LDPE or HDPE polyethylene lay flat tubing, or “polythene” lay flat tubing.

Bioplastic biodegradable lay flat tubing is now available made from ASTM D 6400 compliant Cereplast polylactic acid, or PLA.













Made by the blown film process, only lay flat tubing will work when a seamless, pinhole-free tube is required. Slit sealed poly tubing is not as strong and has inherent pinholes.

Lay flat tubing has many applications. The most common is heat sealed bottom seal bags. Tubular lay flat bottom seal bags can be either mass produced or made with a thermal impulse heat sealer for packaging parts of varying length.

Lay flat tubing is widely used for institutional food packaging by clipping tubes filled with product at each end. These are “cook-chilled” for later use. Handle bags are usually heat sealed at the opposite end.

Lay flat tubing is also a popular choice for portion-controlled meat packaging. Brentwood Plastics manufactures layflat tubing to very tight tolerances to ensure yield and accurate nutrition panel information.

The most often asked question is how to translate lay flat width to diameter and diameter to layflat width.

To calculate lay flat width, multiply diameter X 3.1416 X .5 = layflat width

To calculate diameter, multiply layflat width X .6368 = diameter

Our standard manufacturing tolerance is plus 1/8" / minus zero. For example, 3" layflat can go up to 3.125"

We combine 100% food grade FDA, USDA, Kosher approved resins which all comply with MIL SPEC S/B LP 378 type 1 to make lay flat tubing to your performance standards.

Features such as pigmentation, UVI, plain anti-stat, pink anti-stat, are all available.

Brentwood Plastics has manufactured lay flat tubing for nearly 50 years. We are manufacturers, so we have no stock poly tubing program. As manufacturers, we have rational manufacturing minimums for custom layflat tubing. Our prices are manufacturer direct; our short lead times may surprise you because we have several manufacturing lines.

Capabilities: 1" to 78" 1 mil to 10 mil

Distributors make comparison shipping difficult by stocking different roll lengths than other distributors. They make comparing the true cost per 1,000 feet of per pound of layflat tubing difficult. To save you time we created a spreadsheet to make it easy to compare published distributor prices where you will be able to compare price per 1,000 feet and price per pound.
