The Build-a-Bag system lets you quickly and easily build a vacuum bag to the length needed for your project. I'm offering this product because I've received countless emails from woodworkers with very special vacuum bagging needs. Need a quick custom bag? This is it!
This is a very simple concept.
VS Elite™ and Extreme™ are the ultimate vacuum bagging materials. This film was 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 films have superior resilience and unmatched puncture resistance. Made in the USA.
*Elongation and breaking strength based on ASTMD 412 test method.

Tips from Joe
What is the difference between a Build-a-Bag™ and a regular bag?
With the Build-a-Bag system, you have to adhere the stem body to the bag which takes a bit of time. The Build-a-Bag system has two closures (instead of just one on a pre-assembled bag) which means the vacuum press may run more frequently because the closures always leak a little bit of vacuum.
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.
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.
Is the width measurement the diameter of the bag?
The measurement is the "lay flat" width of the bag.
How do I order a 27" bag in the Extreme thickness?
The VS Extreme™ Build-a-Bag kits are only available in the 54" width at this time. I am working to change this but for now the 27" bags are limited to the Elite thickness only.
What is the pricing breakdown for each Build-a-Bag type?
Elite™ 20 Mil
27" x 6' - $80.00
Elite™ 20 Mil
54" x 6' - $180.00
Extreme™ 30 Mil
54" x 6' - $225.00
Review by Greer Furmage
I have been on the lookout for a vacuum bagging system for a few months so that I may build fiberglass parts for model aircraft. After seeing the build a bag was exactly what I was looking for I took the plunge and ordered one. I found ordering and delivery to be very timely with good feedback as to what was happening. Since its arrival I had no trouble in fitting the bag stem and the first few uses of the bag prove it is very easy to use and does exactly what I want.

The Elite bag is very durable and has nice elongation and returns to original shape with minimal deformation. Perfect for tight corners and complex surfaces. It eliminates bridging and build up of resins and/or glue in air voids.
Review by Josh Newton
I needed a bag that was 20" by 23' and could not find it anywhere but here. I tried several companies and they all wanted a ridiculous sum of money to custom make this size. They also wanted 14 days to make it for me. When I came across this product I knew it would work for me but I don't like online shopping a lot.
But all of my concerns were put to rest very quickly. I emailed some questions and had a reply within an hour from the owner of this company. I then ordered and my bag it showed up at my door 2 days later.
The dual closure system works well and it only took about 10 minutes to bond the valve stem to the bag. The bag material seems to be very durable but I won't know for sure until I've used it a good number of times. I doubt there will be any problems. The material stretches nicely and with all my poking and prodding I feel comfortable in saying that it will be in my shop for a long time.
