Silicone Vacuum Bag For Glass Lamination

For the glass lamination field, you have found the right co-worker. Deer Hunter offers you the best vacuum silicone bag that will help you get the best safety 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, so it is also called silicone rubber vacuum bag or silicone vacuum seal bag. It is highly essential in glass lamination. It is very important to pump the air between the EVA film and glass with a vacuum machine. Make sure NO AIR in the bag. It could be prevented gum spilt on the machine. High-quality silicone vacuum bags can effectively reduce substandard product waste.

Transparent Silicone Vacuum Bag For Glass Lamination

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.

Each bag is a combination of assembled parts with glue-bonding.

Durable & Flexible Silicone For Vacuum Bag

This strong silicone pad meets the most severe industrial tests. It is made of special high-temperature resistant silicone. 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 used during the glass lamination process due to its strength, flexibility and temperature resistance up to 250°C. The bag is made of two pieces of silicone rubber sheets joined with silicone seals. One side of the sheet is textured to facilitate air flow and reduce friction between the composite elements. The air is evacuated from the bag by means of a hose and a nozzle also made of silicone. Equipped with an E or U type seal, it ensures perfect tightness and facilitates closing or opening the bag. 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.

Silicone Vacuum Bags FAQs

1. 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.

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

Standard thickness is 3mm. 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.

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

Colors never impact on the quality. At present, two common colors are white and 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.

4. 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 bag.

5. Can you provide more information about vacuum nozzles?

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