Poly Layflat Tubing


Layflat Tubing

Layflat Tubing

Layflat tubing is now available in polypropylene.

Lay flat / layflat poly tubing is flexible thin seamless plastic tubing pressed flat then wound on rolls. Lay flat tubing is synonymous with layflat tubing or lay-flat tubing.  Brentwood Plastics custom manufactures lay flat tubing made from polyethylenes ( LDPE and HDPE ), polypropylene and other specialty resins. While " slit-seal " tubing is cheap and works for light duty packaging, there is no substitute for seamless tubing in demanding applications.

Shown below are some photos from the lay flat tubing manufacturing process in our factory.  This is our first blown film extrusion line put in service in 1961.

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


Lay flat tubing is widely used as a non-edible casing for portion controlled meat packaging by clipping the end of tubes filled with meat.  These are "cook-chilled" for later use.   

An 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 3.125"

Brentwood Plastics has manufactured lay flat tubing for 53 years. We are manufacturers, so we have no stock poly tubing program. As manufacturers, we have rational manufacturing MOQ 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.
