I have 24 10 gallon containers to put custom whimis labels on, the labels are about 16" x 12".
I'm finding that vinyls, either regular or reflective, arent sticking as well as I'd like them to, I'm thinking about spraying some automotive primer before applying the decals.
Any Thunks??

3M offer a selection of products developed to provide superior adhesion to low surface energy (ie. Polyethylene) plastics. Several of the products have a heavier coat weight of adhesive, which provides for better adhesion to textured surfaces. Call your 3M dealer.
Alternatively, you might want to obtain a sample of Gerber's Permagrip. Good, all purpose solution for many of the types of situations described above.

Be careful with plastic containers. Some of them have an "agent" added that "blooms" or outgases that forms a sort of barrier to help dust from settling. It will detackify most adhesives. How do you find out if they have them? You'll need to ask the supplier of the containers. I found out the hard way once!

The problem is the "gassing off' from the polyethlene itself...if you take a propane torch and pass it over the surface of the bottle (or what ever it is your putting it on) you will see a little almost "fizzle" as the gas's burn off... for a little while your sticker will stick like crazy but alas in a few days it'll be releasing again.
One sure way to put your image on the bottle is by screening it with Unipol Ink (nazdar) even then you must flame the bottle before printing ...but the image will remain as near permanent. (as close as it gets).
Now that I made this point it just occurs to me...what if you flamed it then painted a patch of Unipol on the bottle maybe the sticker would stay better. Hmmm worth the experiment?
Oh by the way Unipol costs about $130. a gallon)and thats the only way it comes).

Maybe I'm missing something here? We (production staff) see to it that all of our h.d.p.e. containers (polyethelene bottles) are labeled correctly everyday, never had a problem with the labels sticking! We don't do anything special, heat treat, etc. ???

Mike, There is/was a product called TiCote that was used as an intermediate coating to allow painting and vinyl onto non-enamel receptive vinyl banners. I believe that ClearStar or ClearShield products have a similar property.

Thanks all for your input. I know from working with 1/8th HDPE sheets (we use it for snowmobile trail markers) that it has to be 'coronated', passed under a high voltage corona wire, prior to applying vinyl, and I know that it has a limited uncoated shelf life before the corona effect dissapates, Jon's discription of 'low surface energy' in part helps explain this procedure. For some reason avery paper labels stick to this stuff like crazy, and will pull apart before the glue lifts, I've got no idea what glues they use...
I think I'll reformat the information into 2 8½x11 labels and use a laminated paper label... gotta do a sample for the customer anyway.
