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.

  • 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.

  1. Very Happy

    High quality bags with good seams and connector. Very happy with quality of product and Joe's service.
    Have bought from him before and will do so again.


  2. Great Buy

    Review by Ron Brunton
    Rating:

    Very glad that I purchased this vacuum bag, together with the lock-on vacuum connector. Even with the cost of international postage, it was still less expensive than anything I could get locally. It is robust, and easier to set up with my vacuum pump than other bags I have used. I was very also very happy with the personalized service I received from Joe.


  3. Everything about the bag speaks to its quality.

    Review by Brian Cozloff

    Ordered two days ago and here it is in my shop. This vacuum bag will undoubtedly get a lot of use so I stepped up and went with the polyurethane version. This was a good deal because comparable vacuum bags are 35% more money. Everything about the bag speaks to its quality. I have to say that I'm impressed with the customer service here. There are few mom-n-pop outfits out there anymore in the internet world. This is a rare example of a company that does things right.


  4. The Cat's Meow

    Review by Herb Yost
    Rating:

    That VS Elite Polyurethane bag is the cat’s meow. In terms of performance, drape, ease of sliding in the work piece, cleanup of glue, etc it’s a Mercedes compared to the Yugo of the vinyl bags I used before. The only thing that sometimes frustrates me is that the VS Elite Polyurethane is so slippery and flexible that it’s hard to get the tubular bag closer on before the glue starts to set. The only time this is not a problem is when the table width is the same size/larger than the width of the bag. I rate this product highly.


  5. Used in a School and It Holds Up to Abuse!

    Review by Mark J
    Rating:

    By far the most durable bag I've ever used. I'm using it with high school students to make among other things, skateboards. It really takes a bit of abuse by the kids but it's still going strong.


  6. Worth the extra money over vinyl... this one conforms nicely.

    Review by Charles Bingham
    Rating:

    If you are thinking that I can just use clamps to press veneer to save money... get used to disappointment. I can't tell you how many times I used clamps and ended up finding areas that bubbled up due to uneven and inadequite clamping pressure.
    I think you will find that the extra money spent is worth it for poly over vinyl.
    Buy one size bigger than you think you will need. You don't want to have you project going right up to the edge of the bag... it can be hard on the seams. Plus, you always seem to have a bigger project come up and you wish you had the larger bag.
    This is a great buy that you will not regret.
    Save yourself anguish, the right tools always make a project go easier. I know I love my vacuum press and wish I had bought it earlier.


  7. Think of it as an investment

    Review by John G.
    Rating:

    These polyurethane bags are built like tanks. I have to admit to abusing my bag on more than one occassion and it's always held strong. Each time I pull the bag out to use it I cant help but smile a bit when I think of the torture its been through. Several months ago I put a huge oversized cylinder in it and pulled a vacuum just "to see what would happen". During the process it dawned on me that I was really stressing the bag and could have killed it. To my surprise, the bag held up and the cyclinder test was a success. Like the other reviewer said, these bags are expensive but in this world you get what you pay for. Think of it as an investment. I think its worth it.


  8. Worth It If You Can Afford It

    Review by Marcus Griffin
    Rating:

    Yes, the polyurethane bags are expensive but you get what you pay for. The material is a silicone-like product (very stretchy) and if you stretch it out, it returns to the normal shape. I chose the 4x4 bag because most of my projects are small card tables.


  9. The Stem Idea Is Excellent

    Review by Gerald Moore
    Rating:

    Everything about this vacuum press bag says QUALITY. The stem idea is excellent. The weld on the bag is flawless. The poly material is more durable than I could have imagined. I use the bag several times each week in my music instrument repair business for holding down parts while glue is drying and each time, I am amazed by how resilient this material is. I doubt you find a better product anywhere and at such a good price. Hats off to Joe and Christine for making this easy and affordable.
