Latest Patents

Martinez's latest patents include an "Extruded zipper with orienting means" and a "method for orienting same." This innovative string zipper is designed for use in the manufacture of material for reclosable plastic bags. The zipper features a first profile and a complementary mating profile that, when interlocked and properly attached to the bag walls, make the bag easy to open from the outside while remaining difficult to open from the inside. One of the profiles is made from polyethylene material that contains an optical brightener, which aids in the proper orientation of the zipper on a sheet of plastic material. During the manufacturing process, the zipper is passed through a black light, allowing the profile with the brightener to be detected. This ensures that the profiles can be easily distinguished and correctly oriented on the sheet material, achieving the desired force differential feature in the final bag.
