Blister Packaging Features

Blisters are gaining increasing popularity among producers of goods of any kind, because they can pack almost any small items. And how is the production of blister packs? To begin to understand that production of blister packs - it's not only the creation of the blisters, but also preparing a cardboard substrate, its sealing and bonding with the plastic part. Therefore, in calculating the time required for the production of blister packaging, should be considered this time. Thus, at the initial stage of manufacture of blisters are held separately. While the traditional cardboard seal printed, you need to prepare myself blister.

Here, the production of blister packs is by thermoforming (or, as it is called vacuum forming). The method is that the polymer film shaped into a matrix without a punch. Manufacturing blister begins with heating the film in a vacuum-molding machine. When it becomes elastic, proceed to the actual molding. In this plot device in which the material is sealed. Bottom of the film summarizes the form (matrix).

It is important to note that the production of blister packaging begins with the design and casting of such a form. Its quality depends on the total production of blister packaging. So, after how to form summed up, from the polymer film is evacuated of air. Creates a pressure difference above and below the film - thanks to this phenomenon and is the production of blister packs. The film adheres to the located below the forms and freezes in that position. Thus ends the main stage production of blister packs. Finally, the finished sheet of the blister is cut from the strip of polymer film. Individual elements cut using a special apparatus. It only remains to connect the blister with cardboard backing - and the production of blister packs is completed. The method of bonding with the substrate is not always the same. You can glue the two parts - such production of blister packaging suggests that it will not be open without damaging the surface of a cardboard substrate. If it is necessary that the package was opened, the edge of the blister bent eaves of the parties, fixing its substrate.
