reply about General Formulations
G.F is the maker for half of the films out there - do a little research and you'll find most of the companies "store brand" is made by G.F. They make good stuff and they make cheap stuff. I have found each is just about worth what you pay for it - which I think is fair and reasonable. When I want CHEAP CHEAP white printable to do a bunch of indoor labels - I use the cheapest Oracal I can get (like $65 a roll delivered (30" x 150ft)) - prints good -overlams good and looks good on the store shelves for a couple years before the product is sold and package tossed.
As far as wraps and high-end stuff - I respectfully bow to those guys who know what they are doing as that is a very exacting science, and you really have to know what you're doing or work for someone who does for a while and they will all have a film / lam combo that seems to work best for their climate, ink and machine, application style, etc.
but generally yes - I've found GF stuff fine. (In fact - I'm not 100% sure they don't also make Oracal?) - lol
