This process applies to metallised films (demetallisation) or complexed aluminum sheets (etching). It consists of removing metal zones in a targeted way and thus making the film transparent. This singularity makes it possible to combine metallised printing elements with transparent areas. PROCESS DESCRIPTION: ROLL TO ROLL MACHINE In order to understand the operation of demetallisation,…
When you want to slit plastic films into yarns, it is compulsory to go through intermediate steps. In fact, when you slit, you always go from the widest width to the narrowest. Thus, the transition from the film stage (ex: 1500mm) to the pancake stage (ex: 58mm) and finally to the yarn stage (ex: 3mm)…
As mentioned in a previous post, the surface tension of the substrates to be glued or printed is an important parameter to take into account during the coating process. Indeed, whether to print on a support or to glue a support with another, the adhesive or the printing ink must be able to spread on…
Requirements finesse of printing for markets such as luxury, food-processing and security involves a choice of different rasterized cylinders. Indeed, the size and the depth of the alveoli, or the engraving technique used are parameters that must be defined before making a gravure cylinder. The engraving of the printing cylinders must be done with great…
Vacuum metallization is a technique that allows to obtain thin layers of metallic deposit on flexible substrates, the most frequently encountered substrates are: Polyester type films (PET), polypropylene (BOPP), nylon (BOPA), and polyethylene (PE), polyimides (Kapton)… Tissue. We will rather focus on aluminum deposition because it is widely used for consumer products (food packaging, insulation…):…
Lamination is the act of assembling two or more materials or supports together. There are 3 important parameters to consider: the “glue” used, the pressure and the temperature. TYPE OF PROCESSES It exists various processes, of which the following is a non-exhaustive list: – Dry lamination: the process of dry lamination is the action of coating…
The transformation of plastic films consists to give technical characteristics to the plastic films. For example, to make a polyester film printable or heat sealable, we coat film with a polish. The formulation is a process that creates varnishes which will give the plastic films the properties required according to their applications. The achievement…
In order to have technical characteristics, such as printability or sealability, plastic films must be coated with a varnish that will give these properties. As the market moves towards more specificities, it becomes imperative to develop custom-made varnishes, responding to increasingly precise specifications. You can develop your own varnish using our facilities, via our two…
