Making your own vacuum press bags

[hunggaur]

Hi folks moving on from the pump to the fitting now onto the bags

I have read that vinyl bags are better as they are stronger. the ones that come in the kits seam to be 300 to 500 micron thick but they seam to be very expensive, so I was thinking about making my own.

However after doing lots and lots of searching of the net I have not been able to anywhere that supplier 300 or 500 micron vinyl

i did find this as an alternative its PVC

I also found this PVC glue

The questions

whats the difference between PVC and vinyl

would pvc make a good strong flexible vacuum press bag based on the links above.

if not can someone point me in the direction of some thick vinyl

many thanks

AFAIK 'vinyl' is just a commonly used name for PVC (polyvinyl chloride). It's very common in bag pressing and is reasonably tough and durable. Polyurethane is superior but costs more.

Not tried them, but what about the vac bags for storing clothes, blankets etc?
