Silicone Vacuum Bag For Laminated Glass

For the glass lamination field, you have found the right co-worker. Deer Hunter offers you heat resistant vacuum silicone bag that will help you create the best laminated glass.

Silicone Vacuum Bag

Silicone Vacuum Bag is a long life and reusable product. It is made up superior silicone rubber sheet used for laminating glass, also called vacuum silicone bag or silicone vacuum seal bag. It is highly essential in glass lamination and very vital to pump the air between EVA film and laminating glass with a vacuum machine. Make sure NO AIR in the vacuum bag. It could be prevented gum spilt on the glass laminating machine. High temperature resistance silicone vacuum bags can effectively reduce substandard product waste.

Product Overview

Each set of silicone vacuum bag consists of one top and one bottom silicone sheets. The top and bottom silicone membrane sheet edges are sophisticatedly embedded to each other, to make sealed room for vacuuming. The interlocking of edges and corners are easy. Edges and corners are specially modified, such as locking strength grow larger when vacuum pressure becomes higher.

Durable & Flexible Silicone For Vacuum Bag

This strong silicone pad meets the most severe industrial tests. It is made of special high temperature resistance silicone rubber sheets. The material will not become brittle after numerous heating and cooling cycles. It is resistant to high-pressure forces when wrapping around glass during vacuum.

Patented Silicone Blankets Edge Seal

Four edges are sealed by silicone strips with E shape design. Top and bottom pad edges are specially designed, providing an airtight interlocking system. The higher the vacuum in between the top and bottom pads, the firmer the edges are sealed.

Application areas

What is Silicone Vacuum Bag?

A silicone vacuum bag is widely used during the glass lamination process due to its strength, flexibility and temperature resistance up to 250c. A silicon bag is made of two pieces of silicone rubber sheets joined with silicone seals. One side of the sheet is textured to aid in air flow and reduce friction between the composite elements. The air is evacuated from the bag by means of a pipe and a suction nozzle also made of silicone. Equipped with E or U type sealing strips on the four edges, it ensures perfect tightness and facilitates closing or opening the bag.

Features and Benefits

4 Steps Help You Get Silicone Vacuum Bags More Easily

Maximum Processing Glass Size of EVA glass laminating machine

E-seals are the top preferred. 90% of our customers choose it. If you want customized U-seals on the edges, please advise.

PTFE mesh can be with hole size 4mm*4mm or 2mm*2mm. It’s an important part to protect the vacuum bag from scraping.

. FAQs

1. Could you let us know if there are any concerns or recommendations for storing the bags for a longer period to ensure they remain in good condition?
(1) Store at room temperature (20-25°C), away from grease and dirty water. Avoid direct sunlight and rain. Lay flat when not in use.
(2) During humid and rainy seasons, place the bags (without sealing and without glass) in the lamination oven. Set the temperature to 100°C and heat for about 20-30 minutes. Then, remove the bag and let it cool. After cooling, it can be processed normally. The PTFE open mesh should also be preheated together.
(3) Always use PTFE open mesh to prevent the glass from scratching or puncturing the bags or workers.
2. Can you make a bag with 4M width X 6M length?

Width 4000mm is currently not available now because of our machine limit. Ideally, we can do width 3.75M. Till now, the biggest bag from our customer’s records is with size 3M X 6M and 3000mm X 8000mm. That was really big&heavy bags and the final packge should be a wooden case.

3. Can you make thickness 2mm or 1mm silicone vacuum bag?

The common thickness is 3mm. No matter it is transparent color or blue color, they are all standard grade quality. We also can make customized bag with THK 2mm or 1mm. But we should bond high tear strength silicone sheet (DH2211) as the top layer and bottom layer.

4. Does the color make a difference on the quality?

Colors never impact on the quality. At present, the common color is white or blue. Actually some customers also regard white color as translucent or transparent color. Somehow, in 2022 more and more customers are picking up blue color.

5. What is the distinction between External size and working area?

Usually customers tell us a size firstly, for example 1800mm X 3300mm. By default, we regard it as external size (width x length); so the real working area will be smaller than 1800mm X 3300mm. But one thing we must guarantee is that your machine’s space is big enough to accommodate the vacuum bag.

6. Can you offer PTFE mesh for the bag?

Yes, we can. In order to support the extraction of air from the space of the silicone vacuum bag, it is good practice to additionally insert a PTFE open mesh inside. Lack of mesh can seal the sheet on the glass and create an air bubble, which can result in inaccurate extraction of air and defects in the produced material. However, the use of PTFE mesh is only an example, any material can be used as long as it is resistant to higher temperature.

7. Can you provide more information about vacuum nozzles?

Vacuum nozzles (ports) and vacuum tubes (hoses) are important parts.

8. Can you provide more information about vacuum tubes?

Outer Diameter 12mm Vacuum Tube

9. For glass lamination: silicone vacuum bags or silicone blankets?

Both silicone vacuum bags and silicone blankets are utilized in the manufacturing process of laminated glass. Silicone vacuum bags find their primary application in EVA lamination machines, providing a crucial component for the lamination process.

On the other hand, silicone blankets are designed for use in autoclaves with high energy consumption and intricate procedures. With these distinct purposes, selecting the appropriate type for your specific application becomes a straightforward task.

I just wanted to express my sincerest gratitude for the great service we received from Deer Hunter about the best vacuum silicone bag. We greatly appreciated their prompt responses and the opinions they provided. For we changed E seals to U seals. Now the sealing edges are still working very well.
