Method of ensuring matching labels between primary and secondary packaging of a product, uses code written in micro print illegible to naked eye to identify product and associate it with its secondary packaging

摘要

The primary package has a label including the product brand, and the secondary packaging has a code mark (5) which enables its identification when the product is sold. An auxiliary mark with a code (6) individualizes the product in the primary package. This mark is in small characters that are illegible to the naked eye. The codes (5,6) are held in a computer database (8) to allow validation.
