Abstract
A frangible laminate includes first, second and third webs, and the second web is positioned between the first and third webs. The forming of the frangible laminate includes adhesively bonding a first plurality of sections of the second web to the first web, applying release material in order to inhibit at least some of any bonding between the first plurality of sections of the second web and the third web, and adhesively bonding a second plurality of sections of the second web to the third web. The frangible laminate is separated into a first laminate and a second laminate, so that the first laminate includes the first web and the first plurality of sections of the second web, and the second laminate includes the third web and the second plurality of sections of the second web.
Claims13
A laminate comprising:
- a plurality of sections of microwave energy interactive active material, wherein sections of the plurality of sections of microwave energy interactive active material are at least partially spaced apart from one another so that gaps are respectively between the sections;
- at least one substrate for supporting the sections;
- and
- adhesive material connecting the sections to the substrate so that the adhesive material is positioned between the substrate and the sections, wherein
- a side of the adhesive material defines both a plurality of protrusions of the adhesive material and a plurality of recessed surfaces of the adhesive material,
- recessed surfaces of the plurality of recessed surfaces are respectively positioned between protrusions of the plurality of protrusions, and
- the protrusions of the adhesive material are respectively in opposing face-to-face contact with the sections of microwave energy interactive active material.
A system for forming a laminate comprising a pattern of microwave energy interactive material, the system comprising:
- a first laminating station for forming an initial laminate, and a second laminating station positioned downstream from the first laminating station for forming a frangible laminate comprising first, second and third webs, wherein the first laminating station is configured for causing the initial laminate to comprise the first and second webs, and the second laminating station is configured for causing the second web to be positioned between the first and third webs in the frangible laminate;
- at least one applicator positioned between the first and second laminating stations for applying release material in a predetermined pattern between the second and third webs;
- and
- a delaminating station positioned downstream from the second laminating station for separating the frangible laminate into parts comprising a first laminate and a second laminate, so that the first laminate comprises the first web and a first plurality of sections of the second web, and the second laminate comprises the third web and a second plurality of sections of the second web.
