Vacuum materials - Vacuum Bags:

    from Vacuum bags Nylon to Vacuum bags Silicone, spares, and tools needed for the vacuum laminated system.

    1] Vacuum Bags Nylon are Tough but flexible co-extruded  disposable bags suitable for autoclave-free and high pressure autoclave laminating and offered in several colors.
        The colors indicate the maximum temperature.  
        Besides the color there are several type vacuum bags to simplify the production of for example complex shapes, and deliver benefits that speed up the manufacturing process.
        Different types:
        • LTX = (V-sheet) double folded  • LFT = tube form  • SHT = single open
        Different temperatures:
        Vacuum Bag Green: 200ºC [suitable for autoclave/autoclave-free]
        Vacuum Bag Purple: 170ºC [suitable for autoclave/autoclave-free]
        Vacuum Bag Yellow: 150ºC [suitable for autoclave-free]

    2] Alternative option for vacuum bags are Vacuum Bags Silicone:
        Vacuum forming can be a time consuming process, and Reusable Vacuum bag Silicone can benefit your process.
        They can be re-used multipe times and are environmentally friendly – creating less waste for your company.

    3] Alternative option for Vacuum bags Nylon are Vacuum Silicone Sheets which can be used multiple times and does not remember the shape of the laminated objects. 
        Silicon sheet is an excellent alternative to a highly-quality way of vacuuming without a disposable Vacuum bag Nylon. Suitable for autoclave and autoclave-free ovens. 
        These sheets comes in several thicknesses 1mm, 2mm, 3mm. Silicone sheets are often used in a so called ‘Trolley’ (table) with up to 10 levels (racks).
        This table can be put into your laminating oven. Each level has a top and bottom heat resistant silicon sheet in thickness of 1mm, 2mm or 3mm.
        Under pressure the silicon sheets press the prepared glass with interlayer together. This system eliminates the use of disposable vacuum bag
        or you can combine the disposable Vacuum bag Nylon when you have complex glass shapes or laminate with EVA.
        Silicon sheet is often used in combination with a reusable PTFE ((polytetrafluorethyleen) teflon mesh for maximum air exhaust between glass and interlayer
        while vacuuming in high temperatures and pressure conditions.

How to use the Vacuum bag Nylon in your laminating process ?

    If you choose to laminate with Vacuum bags Nylon the process is as following:

    First    :  First make sure to prepare the glass and interlayer in a clean room. Glass must be proper clean, Interlayer must be proper clean. 
                  Ensure that the conditions in your lay-up room have the right conditions. Crucial to the process is the quality and condition of the used materials.
    Step 1 :  Cut a proper size Vacuum bag Nylon which suits your laminated glass. Make sure the nylon bag is at least 10 cm bigger on each side.
    Step 2 :  Seal the Vacuum bags Nylon and leave 1 side open, if you used the LFT tube form you need less sealing. Sealing can be done with a digital heat sealer with temperature control.
                  The sealer is permanently heated and has spring loaded cooling bars, that are adjusted automatically to the respective film thickness. 
                  An alternative is the use of an acrylic foam tape, called Heat resistant black tape.
    Step 3 :  Adjust breathable tape on all sides of the glass to ensure that both glass panels not shifting during the process - or to prevent the interlayer to flow outside the glass.
                  Tape comes in color blue or green with a maximum temperature resistance up to 220°C.
    Step 4 :  Apply peel ply (white silk nylon) around all sides of the glass. The use of this release film will prevent other consumable materials (such as breather) sticking to the laminate.
                  Peel ply conduct air at vacuuming and does not distort interlayer. Peel ply has a maximum temperature of 108°C and comes in several widths.
                  Peel Ply prevents sticking to the interlayer, and cunducts air while vacuuming. Peel ply strips easy, clearly and quickly from different interlayers.
    Step 5 :  Apply breather around all sides of the glass. Breather allows constant uniform vacuum flow, protects the vacuum film. 
                  To safe some time in your laminating process you can order the peel ply and breather stiched together. This means that the peel ply is stiched on the breather.
    Step 6 :  Put the prepared glass sheet in to the Vacuum bag Nylon. (The glass sheet with the tape, peel ply, breather.)
    Step 7 :  In this step you prepare the glass sheet to get all air out of the Vacuum bag Nylon, but first you need to connect a vacuum valve into the Vacuum Bag Nylon.
                  To connect the vacuum valve to the edges for de-airing, place an extra piece of breather on the glass inside the Vacuum bag Nylon. To be placed where you connect the vacuum valve.
    Step 8 :  Vacuum valve is needed for the connection to the vacuum line. The Vacuum valve has a bottom plate (the lower part called base) which can be unscrewed. 
                  Unscrew the bottom plate from the vacuum valve and put the bottom plate on top of the extra breather inside the vacuum bag. Ensure that this part is inside the Vacuum bag Nylon.
    Step 9 :  Cut a small hole out of the Vacuum bag Nylon in order to connect it to the lower part. Cut a tiny small hole in the Vacuum bag Nylon. 
                  Make sure that the hole is not too big other wise air will get loose and vacuum will not succeed.
    Step 10: Screw the vacuum valve and the bottom part of the vacuum valve together.
    Step 11: There is still one side open of the Vacuum bag Nylon, seal the last side of the Vacuum bag Nylon. Make sure that all sides are sealed properly. If necessary seal all sides one more time.
    Step 12: Connect the vacuum hose to the vacuum valve. The vacuum valve has a male quick connector and the vacuum hose has a female quick connector. 
                  Providing there are no leaks, the laminate can now be placed into an autoclave or autoclave free system if heat and/or pressure is required. 
                   
    The prepared glass sheet is ready for laminating.
