The latest in packaging.
For a few years now used as industrial packaging. It is similar to a
blister pack, as the tray is placed on the machine with the product
inside, then a card is added which is not used as the base however, as
another movement is made to place a sheet of plastic over it.
The machine then welds the tray to the sheet of plastic through a vibrating heated movement.
Total transparency and untouched by naked hands make this sort of packaging the most advanced in the field.
