Laminating vacuum bag for autoclave – ABR

The ABR vacuum bag

Laminating vacuum bag for autoclave comes in the form of a flexible envelope equipped with a simple, fast and airtight closure system as well as a vacuum exhaust system over its entire internal surface. It enables deairing of complexes and withstands high temperatures in the furnace or oven. Many users around the world are satisfied with this tool.

User / use

Automobile industry: complete EVA cycle, PVB pre-lamination, autoclave finishing after baking in the furnace or automatic oven, lamination of specific glass parts.

Architectural industry: glass partitions, safety columns, glass with acoustic properties, anti-UV glazing, balustrades.

Military industry: lamination of armoured glass.

Composite industry: compacting and crosslinking of pre-impregnated composite plies.

General industry: LCD screens, solar panels

Technical characteristics

Our laminating vacuum bag for autoclave and their accessories are vulcanised in bulk (similar to tire manufacture), giving them very high strength and excellent flexibility.

Various types of simple and quick closures: rubber profile gasket and fold closure, which gives them an excellent seal

The internal exhaust layer is anti-stick and is cleaned by simply wiping with a rag – no interlayer adheres. This anti-pollution system limits production residue and recurrent cleaning.


ABR vacuum bags are used in manual flat laminating processes, for glass with curves, perforations, integrated elements, different thicknesses and sizes, various shapes and multi-layer complexes.

ABR bags are suitable for temperatures up to 140°C / 285°F.

The bags allow an optimal vacuum of -0.99 mbar to be obtained.

Their quick and simple closure system limits handling time and prevents scratching the glass when closing.

They can be used horizontally or vertically on a trolley or table.

The vacuum bag complex has been specifically developed to provide excellent thermal conductivity and thereby limit the cycle time.

It is a versatile laminating and deairing tool, robust and with a very long life span.

Its elasticity allows for folding along the vacuum channel, which limits its volume for storage.

The use of reusable vacuum bags makes it possible to limit the ecological footprint and reduce production costs by depreciation.


The bag is divided into 3 areas:

  • The body of the bag is anti-stick and provides exhaust. In contact with the glass, it provides optimal processing.
  • Quick and convenient seal closure.
  • Exhaust system with Ø10 notched vacuum socket.


Our technical department designs vacuum bags adapted to your needs. We make bags that can reach dimensions of 6600X2600mm. Do not hesitate to share your problems with us (storage, environment, temperature, positioning in the furnace). We will add eyelets, fastening tabs for vertical bags, marking, specific vacuum fittings, sheaths for lifting strap, exhaust grills, etc.)

Simtech can carry out process optimisation studies incorporating your constraints and allowing you to optimise your production and adapt to your installations. These studies can also be carried out on your site.
