LEADER IN FLEXIBLE AND SEALABLE PACKAGING Minigrip Grip-Pak is a company founded about 40 years ago to commercially exploit the Japanese Minigrip patent for the production of resealable packaging in flexible plastic material. With this in mind, Minigrip Grip-pak produced and sold the first bag with a Minigrip closure system in Italy. A feature of the Minigrip patent is that the hinge that makes the envelope resealable is extruded directly with the envelope, with which it forms a single body, unlike competing products, which are instead applied later.
