The thermoforming process has undergone a very important evolution parallel to the development of new technologies and in parallel to the increasing demands of the market.
The European market differs in certain design criteria and use of materials in relation to those used in the American or Asian markets.
For example, the use of rigid PVC films as raw material to manufacture packaging is perfectly accepted in the Asian market but not accepted in the European market due to environmental regulations. This significantly alters the operating parameters used in thermoforming machines. For this reason, today there is a wide variety of thermoforming machines of different commercial brands that adapt to all the processes required by the industry.
Thus, it is possible to have a machine that simply manufactures a container semi-automatically or with a single thermoforming machine that, in addition to automatically thermoforming the rigid polymer film, fills it with the product to be marketed, cuts it to size, labels it and packages it, leaving it ready for distribution.
Today this thermoforming packaging technology is applied to areas as varied as pharmaceutical products, non-food products and food products, with a very wide technological application field given the different versions depending on the need to be covered.
In thermoformed food packaging, products that were traditionally packaged in metal cans or glass jars are now being packaged in thermoformed containers.
The technological development of the process and of thermoforming machines allows the use of new materials with special barrier properties that prevent the packaged product from being affected by undesired atmospheres, or that can withstand sterilisation processes, providing new solutions for a growing market.
It is necessary to be prepared for new applications from their design, mechanically, chemically and structurally, as well as to apply the design to obtain innovative aesthetics.
