Flexible packaging lamination generates air bubbles, five kinds of situations a net!

Flexible packaging lamination generates air bubbles, five kinds of situations a net!

In the lamination process, as long as the two layers of film are not completely laminated, there is a difference in transparency, and when the lamination is laminated, the water flow between the film layers is not flat, or the surface energy of the film is not reached, or the amount of glue coating is insufficient, etc., bubbles will follow. In this paper, we mainly elaborate on five kinds of bubbles generated by insufficient glue application, poor drying, blocking, thicker film from the laminating hot rollers with air, uneven laminating hot rollers and pressure rollers, etc., and detail the solutions.

Dry laminator tension setting law, simple and practical!

Dry laminator tension setting law, simple and practical!

The tension value is set according to the properties of the substrate, such as the substrate thickness, tensile strength, hardness, etc., and the specifications of the film roll. Generally speaking, the initial tension of the substrate with high tensile strength, hardness and thickness is relatively large (e.g. PET), while the initial value of the tension of the substrate with low tensile strength and high stretch rate is relatively small (e.g. BOPP, PE); the wider the film roll, the larger the initial tension. In addition, the following factors will also affect the tension control.
