The invention relates to a method destined for the manufacture of rigid plastic and metal packing items characterised by compressible folds which, along with the final shape of the packing item constitute, after compression, codes inputted on a database. Both, compressed and uncompressed packages are scanned so that the manufacturer’s name, the type and colour of the package as well as the kind of the product contained therein can be recognised by a computer via the codes of the folds and the codes of the final shape of the package. Inside and on both fold-free sides of the packing material, there exist clips which are mutually engaged when in complete compressed condition. The invention is destined for the selection and retrieval of empty packages from waste. |
