Product Description


The VS Elite™ vacuum bagging material has been designed for VeneerSupplies.com using an advanced thermoplastic polyurethane that can withstand pressures exceeding 3,750+ psi and stretch more than 6 times its width and length*. Our polyurethane film has superior resilience and unmatched puncture resistance. Made in the USA. 

Each bag is welded with a state-of-the-art custom RF welding machine operating at 7,000 watts and 50 lb/in of pressure. This exact combination of frequency and clamp strength yields the most durable and airtight seam available. Each bag then undergoes a series of inspections including a final check that I do prior to shipment.

*Elongation and breaking strength based on ASTMD 412 test method.


Features

  • New Flush-Mount Valve StemNew Flush-Mount Bag Stem - The VS Elite vacuum bag also includes our new flush-mount bag stem assembly that allows you to use the full length of the vacuum bag without worry of project surface damage. A specially designed 2.5" diameter 50 mil flange is molded onto the polyurethane stem body and is permanently welded onto each bag. This creates a 70 mil total thickness reinforcement area for maximum durability. Please note that a lock-on connector is required to attach your vacuum tube to the bag stem.
  •  
  • Lubricant Infusion - VS Elite vacuum bags are infused with a non-transferring lubricant that works in several ways to make vacuum bagging easy and trouble-free. This lubricant prevents most woodworking adhesives from sticking to the bag. Glue that sets on the bag simply peels right off. Unlike traditional urethane material, our lubricant-infused polyurethane allows the user to easily slide the platens and project panel into the bag without "blocking" or binding. The slippery surface makes inserting project panels a breeze.
  •  
  • Superior Resilience - Months of extensive testing resulted in a custom formulation that is unsurpassed in durability. VS Elite bagging material withstands 500% more use than standard 30 mil vinyl yet weighs 33% less.

Product Notes

  • pg-closure-included.gifThe opening on this bag is on the 54" side.
  • Click here to download the PDF instructions.
  • A lock-on connector, which is included with all of our vacuum press kits, is required to connect a vacuum line to this bag.
  • This bag is sealed on three sides. Some users prefer to have two opposing open ends so that a shop helper can assist with loading larger projects from the other end of the bag. To do this, purchase an additional bag closure and simply trim off the end seal.
  • The vacuum stem is mounted in the center (left to right) and approximately 15" in from the bag opening.

How do I attach my vacuum tube to this bag?
Our lock-on connector is required to connect a vacuum tube to this vacuum bag. This connector is included with all of our vacuum press systems.

What else should I know about the bag?
The maximum project size that is listed for this bag is approximate. It will vary because of tolerances in the manufacturing process. The maximum project size will also vary depending on the total thickness of the platens and project. You can maximize the usable size of the bag by using breather mesh instead of a top platen.

Does the vacuum bag have to stay connected to the vacuum press after full vacuum is achieved?
Yes because a perfect seal on a vacuum bag is virtually impossible. Here are some things to consider.

  • Sometimes the bag closure doesn't seat perfectly across the opening.
  • Sometimes the bag stretches a bit after full vacuum is created and then needs a bit of additional vacuum. This happens most often when there is a large project in the bag. You'll hear the vacuum system cycle off (if you have any auto-cycling system) and then turn on again for a few seconds. After that, it may not cycle again for several minutes or even hours.
  • After many uses some bags develop pin holes which can be almost invisible. In those cases, it's best to let the vacuum press keep the bag vacuum under control.

If the vacuum system is disconnected from the bag, you won't know if there is a leak because there is no vacuum gauge on the bag itself. If the bag is connected to a vacuum press system, you can easily see the vacuum level by looking at the gauge on the vacuum press. The vacuum inside the system is the same amount of vacuum inside the bag. If your vacuum press cycles on and off too frequently during a project pressing, you'll know there is a leak and if you can fix it. However if you can't fix the leak, at least the vacuum system will keep manage the vacuum in the bag until the panel is finished.

Does epoxy stick to this polyurethane material?
I have tested the polyurethane with several brands of epoxy purchased from the local hardware store. The epoxy did release from the test samples. However, I've have received differing opinions about this from our customers and my guess is that it depends on the type of epoxy, how much epoxy comes in contact with the material, and how often the vacuum bag is used in this capacity.

Do you offer samples of this polyurethane material?
Yes. Please click here for details.

    I recently purchased an Excel 5 vacuum press system, a VS Extreme 4' x 12' Poly Bag, and a plethora of other supplies.

    The bags are very strong and highly resistant to glue residue. I haven't made any sloppy guile-ups yet, but the few seepage episodes that have happened have not once stuck to the bag.

    Lastly, working with Joe and Christine has been great. Truly a small business operation with excellent customer service.

    I look forward to being a customer for years to come.

    I found this bag to be very easy to work with and is very supple. When vacuum pressing it really molds to the shape of the item. I would recommend the polyurethane bags in any size.
