Minisac Snc has worked in industrial packaging since the early 1960s, when Filippo Costanza started to produce plastic bags in Pero, near Milan. The turning point came in the 1990s: production focussed solely on zippers, enabling the study and development of new profiles and the use of new materials, as well as raising the quality standards of the products offered and the reliability of the service.

In addition to the refinement and modernisation of polyethylene and polypropylene zippers, there began the development of a range of PVC zippers, an item not known at the time and still uncommon given the complexity of processing this polymer.

Currently, Minisac Snc, with six production lines, is leader in the production of plastic zippers, boasting a wide range of polyethylene, polypropylene, PVC and biodegradable, transparent or coloured materials, and also offers to develop new profiles.

Today, the activity is carried out with the same commitment and professionalism by Filippo’s sons Salvatore and Gabriele who, always working at an artisanal level, offer a more direct, flexible and responsible relationship with customers to satisfy any demand, from small to large scale production.

The recognised strengths of our company are quality, flexibility, punctuality and attention to our customers.
