This isn't one of our labs but it looked interesting. Most of our lab equipment is newer than the stuff in this picture
Release papers, release films, masking films and tapes do require evaluation. Lab work is necessary to test release levels or adhesion levels. This lab work can help us get close to the specification that you require.
If you can send us material to work with in the lab, that does help us with our evaluations. This will make our sampling step a little more targeted. I'd say "a lot more targeted" but I wanted to make sure not to raise expectations too high.
Even with lab work, sampling is the typical next step. Our lab just can't duplicate your unique process and conditions, so the proving of our materials has to be in your process.
