A simple visualization of the forming process Vacuum forming machine to produce inner liner/food liner of refrigerator. Vacuum forming is a simplified version of thermoforming, where a sheet of plastic in various forms of High Impact Polystyrene Sheet (HIPS) for low impact products, or ABS for bathroom shower trays, and HDPE for exterior vehicle parts, plus various other types of vacuum ...

Blister packs are created by means of a form-fill-seal process at the pharmaceutical company or designated contract packer. A form-fill-seal process means that the blister pack is created from rolls of flat sheet or film, filled with the pharmaceutical product and closed (sealed) on the same equipment. Such equipment is called a blisterline.
The largest disadvantage of the process is its slow forming rate. Cycle times vary from two minutes to two hours, therefore it is usually used in low volume production applications. [4] [1] Another disadvantage is the non-uniformity of the produced part thickness. [5] Several methods are used to improve the thickness uniformity of SPF parts.
The Vector templates below can be used to derive images with, for example, Inkscape. This is the method with the greatest potential. This is the method with the greatest potential. See Human body diagrams/Inkscape tutorial for a basic description in how to do this.
