In order to guarantee adhesion, it is recommended to keep the pressure on while the temperature in the glueing line remains between 40° – 50°C.
After laminated, we can assess the adhesion by performing an adhesion test by manual peeling. This test makes it possible to understand, we can observe the glue expression that a correctly performed process is shown by the presence of glue on both foil and profile.
In all, to better laminate, the material should remain 24 or 48hours in the same environment as that of the wrapping plant. Because both a physical and a chemical adhesion, not in the production line, but rather during storage.
Relative humidity in the working environment it is important for glue. Therefore, It is recommended that the profile in the correct temperature.
