Label assembly and method of manufacturing

A method of manufacturing a label assembly having two parts comprising:

• co-extruding first and second layers of polymer material having first and second surfaces to form a laminate having a releasable interfacial bond between said first surfaces of said layers
• applying a first adhesive layer to the second surface of said first layer of polymer material such that said laminate is adapted to be adhered to a mounting surface;
• providing a top sheet of material;
• applying a second adhesive layer to a surface of said top sheet;
• and
• joining said top sheet to the second surface of said second layer of polymer material by means of said second layer of adhesive wherein said top sheet and said second layer of polymer material are removable by breaking said releasable interfacial bond.

A label comprising;

• a base stock being constructed of first and second layers of polymer material having first and second surfaces, said first surfaces of each being bonded by controlled adhesion to each other to create a releasable interfacial bond therebetween;
• said second surface of said first layer polymer material being printed with graphic material, and said second layer of polymer material being provided with a layer of adhesive over its second surface for application to a mounting surface;
• a face stock being constructed of a top sheet with first and second surfaces having a layer of adhesive over its second surface so as to be adhered to said base stock on said second surface of said first layer of polymer material and having graphic material printed on said first surface of said face stock;
• a releasable portion being formed when said face stock is adhered to said base stock wherein said face stock and said first layer of polymer material are separable from said base stock by breaking said releasable interfacial bond between said first and second layers of polymer material in said base stock.

A method of making a coupon structure comprising the steps of:

• 1) providing a backing web with a release surface;
• 2) providing a base stock by coextruding first and second layers of polymer material having first and second surfaces to form a laminate having a releasable interfacial bond between said first surfaces of said layers;
• 3) applying an adhesive layer to a bottom surface of said base stock such that said base stock is adapted to be releasably adhered to said backing web on said release surface;
• 4) providing a top sheet of material;
• 5) applying a layer of adhesive to a bottom surface of said top sheet;
• 6) applying said top sheet to said base stock by means of said adhesive layer on said top sheet, whereby said second layer of polymer material may be adhered to a mounting surface by means of said adhesive layer applied thereto upon removal of said backing web, and said top sheet and said first layer of polymer material are removable by breaking said releasable interfacial bond between said first and second layers of polymer material.
