Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
A two side printed message-carrying insert comprising a grease and oil resistant, plastic film laminate adapted for insertion into packages containing food, said laminate including a central core layer of biaxially oriented polymeric film printed on both sides in register with a message to be displayed, a first layer of adhesive disposed above and adjacent said central core layer, a second layer of adhesive disposed below and adjacent said central core layer, a first layer of transparent, grease-resistant, biaxially oriented polymeric film disposed above and adjacent said first layer of adhesive, a second layer of transparent, grease-resistant, biaxially oriented polymeric film disposed below and adjacent said second layer of adhesive, whereby said adhesive and film layers seal the printed message on both sides of said core layer and prevents contact between moisture from the food product and the printing ink disposed on both sides of said central core, resulting in a plastic insert of high clarity which is substantially unaffected by contact with food.
Claim 2
Dependent Claim
164 words
A two side printed message-carrying insert comprising a grease and oil resistant, plastic film laminate adapted for insertion into packages containing food, said laminate including a central core layer of biaxially oriented polymeric film printed on both sides in register with a message to be displayed, a first layer of adhesive disposed above and adjacent said central core layer, a second layer of adhesive disposed below and adjacent said central core layer, a first layer of transparent, grease-resistant, biaxially oriented polymeric film disposed above and adjacent said first layer of adhesive, a second layer of transparent, grease-resistant, biaxially oriented polymeric film disposed below and adjacent said second layer of adhesive, whereby said adhesive and film layers seal the printed message on both sides of said core layer and prevents contact between moisture from the food product and the printing ink disposed on both sides of said central core, resulting in a plastic insert of high clarity which is substantially unaffected by contact with food.
Claim 3
Dependent Claim
19 words
A plastic film laminate as in claim 1 in which said central core layer of polymeric film is opaque.
Claim 4
Dependent Claim
16 words
A plastic film laminate as in claim 1 in which said central core layer is polystyrene.
Claim 5
Dependent Claim
17 words
A plastic film laminate as in claim 1 in which said central core layer is opaque polystyrene.
