OK, thanks, I will.

But, wouldn't just the heated side give, leaving the unheated side to resist the shape change? (this for blister making)

You da man, Frank.

May I pester you with questions about vacuum forming?

Vacuum forming is used in all sorts of consumer products, for blister packaging so you can see the product contained in the package. What kinds of clear, smooth plastic work well for this? Acetate sheet? Acrylic? Lexan?

What is easiest to work with?

Cheapest?

Have you seen the thermoforming and vacuum forming videos on You Tube? From those, it seems that home made vacuum forming machines could be cheap and easy. Your thoughts?

i tried forming plexiglass once and i had more even heating using quartz work lights than a heat gun. it seemed to penetrate inside the plastic, rather than just surface. haven't tried coroplast they gathered up all the big political signs before i had a chance.
