Unit of measure (MOQ): 1 Yard .002” thick x 30” wide x 1 yard long

Description: BMNFLF is a high strength and flexible Nylon material used for the last layer in the vacuum bagging process.  This flat bagging film is made to withstand temperatures in excess of 400 degrees Fahrenheit.  The material can be used at room temp, or used in Ovens or Autoclaves on cures from 250 to 350 degrees.  This material is also a good choice to use when wetting out dry fabric with the resin of your choice.  And because this material is chemically resistant to resins as well as solvents such as MEK and Acetones, this material also works well as a protective barrier over table tops and other surfaces that you may want to keep clean.

Application: To start the application process, cut the material to the desired size and dimensions, remembering to allow for extra material when forming pleats in the vacuum bag.  Even if pleats are not needed, you will want to cut your bag at least 2 Inches larger than your vacuum bagging sealant tape.   Apply bagging film on top of your layup and other bagging materials; apply pressure to the tape all the way around being careful not to leave any creases along the edge that may cause a leak.   After you are satisfied with the application of the bagging material you can then cut the holes in the bag over the probe base and connect the top of the vacuum probe to the probe base.  Now you can apply the vacuum hose to the probe.  As the bag is being sucked down take time to adjust the bag as needed, remember that you do not want to allow bridging in any radius or part contours.  Once your bag is pulled down and you are sure of no leaks you can attach a vacuum gauge and remove the vacuum supply hose and check your bag for leaks.  You do not want to drop the vacuum pressure more that 1”Hg in one minute.  If your bag does not hold at least 22”Hg you will want to check for leaks prior to proceeding to the curing process.  After the materials have cooked off simply remove the bagging film and discard.
