At Rotor Print we not only print materials for flexible packaging, we also have a long history in the combination of monolayer materials to achieve multilayers. With the combination of materials, what we achieve is to provide the container with specific technical characteristics.
We also find products to which coatings are applied, some for visual purposes and others for technical purposes.
Lamination processes can be achieved using three technologies: solvent-based, solvent-free and water-based.
Monolayer materials (PE, PET, PP, etc.) have limited barrier qualities, but the combination of several materials, together with high-performance adhesives, achieves an end product with complex qualities. This is why a large part of the products packaged in flexible packaging are made with multilayers, since they provide the container with the necessary product protection (barriers).
The coating of varnishes or adhesives allows us to provide the end product with extra qualities. Sometimes they are only visual, using varnishes to achieve characteristics such as “Paper like”, “Mate” effect or with a high gloss.
But on the other hand, we can also apply high-performance adhesives to achieve resistance to thermal processes such as sterilisation and pasteurisation.
The combination of monolayer and multilayer materials allows us to achieve an end product with the following technical characteristics características técnicas:
