What is of great interest currently are the newly-developed forms of P-PVC folio. Those are made of different in colour and thickness stream-proof folio. Manufactured in a special way allowing the final seal of the packing to be done by the manufacturer of the item that is subjected to packing. The packings have the standard “euro-opening” which allows usage of the same type of the shelves. The packings which include more packed items are perforated between the separate items for the retailer’s conveniency.
