So i started vacuum forming after building my own vacuum former and everything worked out okay but the plastic is really weak and sensitive. It rips easily and is really flexible and isnt sturdy. I used a type of thermal plastic from amazon. My question is am i using bad plastic? Should a plasticard be better( bacteria recommends these)? Like i see cases from ashen and other people who vacuum form and they look sturdy as heck and not sensitive at all.
