Depends on where they're going to be used and how long clients expect them to last.
For example: I make industrial labels and it's all done with cast and cast laminate. Same as I use for vehicle graphics.
Other things get 4 mil calendared with no lamination. Some 4mil gets laminate.
Without knowing your exact requirements it's impossible to recommend materials.
hahaha you are dmnd right! Thats the question I asked. So, I need a list of the types of vinyl, please. Looks like the PolyGrip is too much. I need a general purpose vinyl for stickers and another vinyl for labels as well as for cardboard. Thank you again!
Most cake, baked goods, etc. boxes are pressed board and have a smooth NFS approved coating on them. If it was me, I'd just use a 6mil, semi-rigid decal material and skip the laminate. If being used on perishable food items and chucked afterwards, I see no point treating these decals like they should last more than a few weeks to a month at the most.
Now that most recycling markets in the U.S. have been obliterated thanks to the trade war our leadership has instigated, cereal boxes and other packaging won't be shipped off to China to deal with anymore, so we need to treat these types of packaging like the throwaway items they have now become.
