The tape has a first heat activated adhesive which is activatable at a first temperature and a second heat activated adhesive which is activatable at a second temperature and both of which are alternatively coated on at least one surface of the tape. The method consists of laminating this aforementioned tape to a packaging substrate by following the process of: placing this tape in or on a laminating machine over the packaging substrate, heating the tape at least to the second temperature while making contact with the packaging substrate, cooling the packaging laminate until the second heat activated adhesive is set and cutting a predetermined portion of the packaging laminate before a second adhesive occurs between the tape and the packaging laminate. ## Claims ### Claim 1 A method for laminating a tape having a first heat activated adhesive which is activatable at a first temperature and a second heat activated adhesive which is activatable at a second temperature being higher than the first temperature, wherein the first heat activated adhesive and the second heat activated adhesive are coated in alternating bands at least on one surface of the tape, to a packaging substrate, the process comprising the steps of: a) positioning in or on a laminating machine the tape at a predetermined position over the packaging substrate; b) heating the tape at least to the second temperature while contacting the tape with the packaging substrate to form a packaging laminate; c) cooling the packaging laminate for setting said second heat activated adhesive to provide a first adhesion between the tape and the packaging substrate; and d) cutting a predetermined portion of the packaging laminate before a second adhesion occurs between the tape and the packaging substrate when the packaging laminate is cooled below the first temperature and the first heat activated adhesive is set to permanently fix the tape to the packaging substrate. ### Claim 2 (depends on 1) The method of claim 1), wherein in step 1)b), the tape is heated by heat generated by the laminating machine. ### Claim 3 (depends on 1) The method of claim 1), wherein in step 1)b), the tape is heated with an external heat source. ### Claim 4 (depends on 3) The method of claim 3), wherein the external heat source is a heat wheel or shoe. ### Claim 5 (depends on 1) The method of claim 1), wherein in step 1)c), the packaging laminate is cooled at room temperature. ### Claim 6 (depends on 1) The method of claim 1), wherein in step 1)c), the packaging laminate is cooled with an external cooling source. ### Claim 7 (depends on 1) The method of claim 1), wherein each of the alternating bands has a width of 2 mm to 50 mm. ### Claim 8 (depends on 7) The method of claim 7), wherein each of the alternating bands has a width of 2 mm to 3 mm. ### Claim 9 (depends on 1) The method of claim 1), wherein each of the alternating bands is disposed at an angle to a longitudinal axis of the tape. ### Claim 10 (depends on 9) The method of claim 9), wherein each of the alternating bands is disposed at 90° to the longitudinal axis of the tape. ### Claim 11 (depends on 1) The method of claim 1), wherein each of the alternating bands is parallel to a longitudinal axis of the tape. ### Claim 12 (depends on 1) The method of claim 1), wherein the first temperature is between 70° C. and 120° C., and the second temperature between 75° C. and 125° C. ### Claim 13 (depends on 12) The method of claim 12), wherein the of second temperature is about 5° C. higher than the first temperature. ### Claim 14 (depends on 13) The method of claim 13), wherein the first temperature is about 105° C. and the second temperature is about 110° C. ### Claim 15 A process for producing a packaging laminate comprising the following steps: a) laminating a tape having a first heat activated adhesive which is activatable at a first temperature and a second heat activated adhesive which is activatable at a second temperature being higher than the first temperature, wherein the first heat activated adhesive and the second heat activated adhesive are coated in alternating bands at least on one surface of the tape, to a packaging substrate; b) positioning in or on a laminating machine the tape at a predetermined position over the packaging substrate; c) heating the tape at least to the second temperature while contacting the tape with the packaging substrate to form the packaging laminate; d) cooling the packaging laminate for setting said second heat activated adhesive to provide a first adhesion between the tape and the packaging substrate; and e) cutting a predetermined portion of the packaging laminate before a second adhesion occurs between the tape and the packaging substrate when the packaging laminate is cooled below the first temperature and the first heat activated adhesive is set to permanently fix the tape to the packaging substrate. ### Claim 16 (depends on 15) The process of claim 15), wherein each of the alternating bands has a width of 2 mm to 50 mm. ### Claim 17 (depends on 16) The process of claim 16), wherein each of the alternating bands has a width of 2 mm to 3 mm. ### Claim 18 (depends on 15) The process of claim 15), wherein each of the alternating bands is disposed at an angle to a longitudinal axis of the tape. ### Claim 19 (depends on 15) The process of claim 15), wherein the first temperature is between 70° C. and 120° C., the second temperature is between 75° C. and 125° C. ### Claim 20 (depends on 19) The process of claim 19), wherein the second temperature is about 5° C. higher than the first temperature.
