a short testimonial:

I had my multilayer packaging solution being analyzed for permeation and chemical resistance by Composite Analytica (https://composite-analytica.com). Their work is fine: it is crystal clear and the report contains the highly sophisticated formulae for multilayer diffusion and time lag. Also for your migration in packaging problem, you could contact them!
