No one is disputing your experience or reference point. The OP is asking for a short term removable. Several manufacturers have a solution, not only 3M. 3M makes fantastic products but they are not the one and only.
Possibly plasticizer migration, it happens when material is past its shelf life, stored poorly. Have also seen it with some banner materials when printed with a latex printer. Is it possible the welded and grommeted material sits around longer at the suppliers?
Just to add to this great information. General Formulations has a product similar to the 3651 but it is optically clear. I believe it is GF255 and is also a removable product.
3M and EFI have a warranty program for their uv inks/material for wraps. Most UV inks used on flatbeds are not flexible enough and are designed for rigid stocks. Curing may also impact the adhesion etc. You can print with UV but not everyone has a 6 figure printer. Roll to toll solvent base...

Just my thoughts based on my reference point. Others may have a better reply.
The UV output of the lamps (millijoules and millwatts) deteriorate over time and are typically changed around 500 to 1000 hours (depending on the printer).
As a result the substrates that cure at 70% may need 100%...
There are UV inks for rigid stocks and UV inks for flexible stocks that are also compatible with PVC. If the laminate is peeling or falling off, then there is most likely a curing issue.
