We offer you a complete programme of the renowned German manufacturer Progress packaging. All products are based on the system of automatic closing; after closing they cannot be opened without it being noticeable.
The products differ with regard to the intention of use or with regard to the product which is to be delivered, and roughly speaking they can be divided into envelopes for letters, books and media, boxes, the so called long boxes and plastic envelopes. The photos below show some advantages when using these products.
