The European Patent

The European Patent Office, based in Munich, granted the company Inter – folia Sp. z o. o. European patent no 3323626

The subject of patent protection is

                    the method of making reinforcement of the punched part of foil pocket for documents.

Appropriate folding of the finished foil in the punching area creates a reinforcement of the left edge of the product.

The introduction of color in the place of reinforcement additionally simplifies the segregation of documents.

The innovative method of producing pockets eliminates the need to introduce an additional reinforcing strip,

often made of a complex plastic composition.

EKO punched pockets are made of one type and one belt of 3-layer PP foil,

manufactured as a result of the implemented waste-free technological process.
