Blue Vacuum Silicone Bag For Glass Laminating Machine

For the glass laminating field, you have found the right co-worker. Deer Hunter offers you a high elasticity silicone vacuum bag to create the best safety laminated glass.

Vacuum Silicone Bag

Silicone vacuum bags are highly essential in glass lamination, packing glass panels, EVA film interlayers and decorative inserts together and forming a vacuum inside that ensures successful completion of the process. 

Blue Vacuum Silicone Bag For Eva Glass Lamination

Product Overview

A set of vacuum silicone bag consists of one top silicone blanket and one bottom silicone sheet. Each vacuum bag is a combination of assembled parts with glue-bonding.

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 is easy. Edges and corners are specially modified, if locking strength grows larger when vacuum pressure becomes higher.

Aging Resistance Silicone Rubber For Vacuum Bag

High elasticity silicone sheets meet the most severe industrial tests. It resists abrasion, wears and tear up to a certain high degree. The material will not become brittle after numerous heating and cooling cycles. It is resistant to high vacuum 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 silicone blanket begins to wrap downwards along glass edges until it gets in physically zero-gap contact with bottom silicone sheet. 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 Vacuum Silicone Bag?

A vacuum silicone bag is widely used in EVA glass lamination process, thanks to their remarkable anti corrosive and high temperature resistance. The silicone vacuum bag is made of two pieces of silicone rubber sheets joined with sealing strips on the edges and corners. The bottom silicone sheet is textured to aid in airflow and reduce friction between the safety laminated glass. The air is evacuated from the bag by means of a hose and a nozzle also made of silicone rubber. Equipped with an E or U type seal, it ensures perfect tightness and facilitates closing or opening the bag.

Features and Benefits

Reusable . 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 blanket and bottom silicone sheet.

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; 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 silicone vacuum seal 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 silicone blanket on the glass and create air bubbles, resulting in inaccurate extraction of air and defects on the glass sheets. However, the use of PTFE mesh is only an example, other materials can be replaced as long as it is EVA resistance.

7. Can you provide more information about vacuum nozzles?

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

What Do Our Clients Say

I want to thank the team at deer hunter who made it possible for me to buy from China. The bag I received was the same as I expected. It met the quality standards and I would recommend DH to anyone in glass lamination.
