Abstract: A method for applying a cold seal adhesive is disclosed. The method includes the steps of delivering a cold seal adhesive to a nip between a rotating metering roller and an adjacent rotating transfer roller having a transfer surface, transferring a quantity of adhesive to the transfer surface, rotating the transfer roller whereby the transfer surface contacts a printing die mounted to a rotating die roller disposed adjacent to the transfer roller, rotating the die roller whereby the printing die contacts the at least one adhesive region on the interior surface of the housing and transfers at least a second portion of the quantity of adhesive from the printing die to the at least one adhesive region forming a film as the housing advances between the die roller and the impression roller, the film having a thickness between 0.0015-0.007 inches, and drying the adhesive on the housing.

Abstract: According to one aspect of the present disclosure, a method of applying a cold seal cohesive for product packaging is disclosed, the method including the steps of delivering a cold seal adhesive to a chambered doctor blade disposed adjacent a rotating transfer roller; transferring a quantity of adhesive to a transfer surface; rotating the transfer roller to contact a printing die mounted to a rotating die roller such that at least a first portion of the quantity of adhesive is transferred to the printing die; feeding a housing between the die roller and an adjacent rotating impression roller; rotating the die roller such that the printing die contacts the housing and transfers a portion of the quantity of adhesive from the printing die to the housing; and drying the adhesive on the housing, where the adhesive is a latex-based, dry-tack adhesive, with a viscosity of no more than 450 centipoize.

Abstract: According to one aspect of the present disclosure, a cold cohesive packaging system using tear resistant tape includes a top sheet having an interior surface and at least one top cohesive region defined on the interior surface; a bottom sheet having a bottom interior surface and at least one bottom cohesive region defined on the bottom interior surface; at least one strip embedded in the top sheet or the bottom sheet, the at least one strip being resistant to tearing; and a cohesive, wherein the cohesive is applied in liquid form and adheres as a film to the at least one top cohesive region and the at least one bottom cohesive region, where the cohesive is capable of permanently bonding the top sheet to the bottom sheet when a pressure is applied, and wherein the cohesive comprises a latex-based cohesive with a viscosity of no more than 450 centipoise.

Abstract: According to one aspect of the present disclosure, a cold seal adhesive material is disclosed. The cold seal adhesive material includes a latex emulsion comprising between 15 to 65 percent of the adhesive by weight and ammoniated water. The adhesive viscosity is between 10 and 450 centipoise at 25 degrees Celsius, the density is between 8.0 and 9.0 pounds per gallon at 25 degrees Celsius, and the basicity is between 9.5 and 12 pH. The adhesive is adapted to be applied as a film on a substrate by a modified flexographic printing press process at a rate of at least 1,750 square feet per minute of the substrate without agglomeration of the adhesive, where the film has a film weight between 0.01 and 0.04 grams per square inch of the substrate and must be compressed with a sealing pressure to produce a cohesive bond between two or more adhesive regions.
