Dear Khun Amphol,
I would like to come back to the issue you have mentioned below regarding
“Produced by dry lamination process”
I had noted that dry lamination was used as from the beginning …
I had redorded the following glue/adhesive system:
Brilliant face Aluminum 30 µm
Glue System Takeda 6260 / I3000
PET 12 µm,
Glue System Takeda PP3210 / I3072
PE 60 µm extruded
We hope that the type of lamination and use of glues and adhesives have not been changed but simply primer was added to the surface as this would require new tests regarding the chemical resistance of the foil.
Time is getting critical, please kindly let us know a.s.a.p.
