Blister Packs

Production of blister packs – is a multistep process that begins with the design of the future of packaging and design matrix, and ends laying products. Production of blister packs is, in most cases, from a cardboard substrate and manufacture of the blister. Efforts of designers focused on the design of the substrate – it is sealed, as any other non-transparent packaging. Blisters generally follows the shape of the product. Therefore, the production of blister packs necessarily includes the matrix, which will be made whole party. Production of blister packs is largely dependent on quality of the matrix and the precision with which it was designed and executed. When the preparatory stage is completed, you can begin the actual production of blisters. For this matrix is set in a vacuum-forming apparatus.

It also served the polymer film from which the proceedings are blister packaging. The film is heated to a temperature where it becomes flexible and elastic. Bottom it provides the forms. Next production of blister packs is using the method of vacuum molding. In this case, between the matrix and the film creates a low pressure (or vacuum), because of what the film takes shape. The next stage in the production of blister – a blister from the cutting of sheet film. Typically, the production of blister packs is automated: machines for forming, cutting and trimming are joined into a single line.

However, the final separation of the blisters is often used manual selection. Production of blister packaging varies depending on how the blister is attached to the substrate. If it sticks, it is necessary for the region Apply glue thermo varnish, put item in a blister, connect with cardboard and heated to a temperature at which the lacquer turns into glue. If, however, is the production of blister packs, which can be removed from the substrate is then ready Blister heated to elasticity, bend edges on three sides, and then inserted into the resulting "pocket" the cardboard backing.
