Title: APPARATUS AND METHOD FOR PRODUCING MICROPERFORATED PATCHES AND LABELS APPLICABLE TO MODIFIED ATMOSPHERE PACKAGING
Abstract:
An apparatus and method for producing microperforated patches for MAP includes drilling or punching microperforations through continuously advancing label stock. Holes can be drilled by at least one microperforating laser traversed across the label stock as it advances, a laser beam deflected or split using a servo-driven galvanometer, beam splitters, or a plurality of mirrors, or by drills mounted into a rotating die cylinder across which the stock passes as it is advanced. Numbers and sizes of microperforations can be adjusted by manipulation of laser control parameters, or by exchange of die cylinders. The laser can be a CO2 laser with between 10W and 100W output. The drills can be carbide drills. The label stock is typically 6-18 inches wide, and can include an adhesive covered by a release sheet. The stock to be microperforated can include separate rows of labels or can be suitable for die-cutting after microperforation.
