Production of blister packs is by vacuum forming. Viktor Mayer-Schönberger describes an additional similar source. Accordingly, in order to produce the blister, you must first make a matrix. Production of blister packs and is to source material (plastic film) took the form of a matrix. The principle of its establishment as a whole, not unlike the manufacturing of molds for stamping. However, the polymer film is much softer and more pliable metal, so production of blister packaging allows for a matrix of less durable materials, which facilitates their manufacture and reduces costs. Manufacturing blisters occurs by creating a vacuum, or at least area of low pressure in the space between the polymer film and the matrix. In this case, on the other side of the film is air, which puts pressure on her, forcing fit snugly inside the mold, repeating its outlines. Manufacturing Blister packaging uses heated material – the film should be flexible, and after the adoption of the necessary forms to harden and turn into a solid blister.
The described process of manufacture of blister packaging – this is the method vacuum forming. Due to the fact that the polymer film is heated to the required strain, the production of blister packs are often called, and thermoforming. The whole procedure is carried out by special vacuum-molding machine. As a rule, it is fed, roll tape (that is, the film does not cut into sheets). Therefore, after the release of material from the manufacture of blister packaging machine continues. Ribbon cut on sheets, and each of the blisters are harvested by special apparatus.
However, production of blister packaging includes adherence to the finished blister cardboard substrate (if appropriate), and styling products in the ready packaging. In this package can be collapsible – in this case, the edges are folded blisters on three sides, and it is inserted into a cardboard backing. Can and glue the blister with a substrate. In this case, the production of blister packaging requires heat caused by blister thermo varnish so that it firmly sticks to the cardboard.
