Abstract:
A tape closure system is shown and described herein. The tape closure system includes a first tape component having a pressure sensitive adhesive and a second tape component having a pressure sensitive adhesive, where at least one of the pressure sensitive adhesives has a modified surface to reduce the tack of the surface such that when the first and second pressure adhesives are brought into contact with one another they may sufficiently adhere to one another to form a seal but are still separable from one another and able to be repeatedly opened and sealed. Such a tape may be manufactured through high speed manufacturing processes and wound into large master rolls. In the roll configuration, the modified surface contacts the backside of the liner and experiences compressive forces in the roll. Due to the compressive forces, a part of the modified surface may get pushed into the PSA, thereby affecting the properties of the modified adhesive. An embodiment of this invention provides an embossed liner with spacers that nest the modified adhesive surface when it is self-wound, thereby preventing the deterioration of the adhesive properties. An embodiment of the invention is a method by which the adhesive-based closure system can be applied on to a flexible packaging material on a Form Fill Seal packaging machine in one of three ways: (1) In a form of a tape from a spool. (2) In a form of an adhesive dispensed directly on to flexible packaging material. (3) In form of a tape dispensed from a roll of pressure sensitive adhesive. Another embodiment of the invention is a double sided tape with the detack layer on both sides. An embodiment of the present invention can also be used for temporary closure with no damage done to the underlying system.
Abstract:
Adhesive tapes and methods for splicing low surface energy substrates with flying splices are provided. An example adhesive tape comprises an adhesive layer and a backing adjacent to the adhesive layer. The adhesive layer comprises a first adhesive comprising a higher shear resistance, cohesive strength, and surface energy relative to a second adhesive, and the second adhesive comprises a higher tack for low surface energy substrates relative to the first adhesive. The second adhesive is different from the first adhesive. The second adhesive is adjacent to the first adhesive and there is substantially no overlap between the first adhesive and second adhesive.
Abstract:
The present invention relates to an adhesive structure (6) comprising a substrate (1) and an adhesive coating (7) is applied to the substrate. The adhesive coating is applied to the substrate so that the thickness (z) of the coating varies in at least one direction (x, y).
Abstract:
A flooring tape, for securing a first flooring unit adjacent to a second flooring unit is described. The flooring tape has two sides, a first adhesive side and a second non-adhesive side. The first adhesive side is made up of three portions, a first portion, a second portion and a third portion, the third portion positioned between the first and second portions. The first portion and the second portion have a flooring adhesive layer applied thereto for forming a bond with the first and second flooring units. The third portion has a water resistant adhesive layer applied thereto.
Abstract:
The present invention is a two-part adhesive layer including a first, optically clear adhesive composition and a second, light-blocking adhesive composition substantially surrounding the first, optically clear adhesive composition.
Abstract:
An adhesive film that includes a first region having a first hardness, and second regions disposed on opposing sides of the first region and having a second hardness that is greater than the first hardness.
Abstract:
A substrate, such as, for example, a flap member of a pinch-bottom product bag, and a method of making the same, comprises a hot melt adhesive disposed upon the substrate so as to comprise first horizontally spaced upstanding portions whereby adhesive blocking is effectively eliminated or significantly reduced. A fiberized hot melt adhesive overcoat/overspray may also be disposed atop the hot melt adhesive to further assure the elimination or reduction in the adhesive blocking. The fiberized hot melt adhesive may also be used in conjunction with a conventionally applied hot melt adhesive base or foundation upon the substrate or deposited directly onto the substrate.
Abstract:
An article including a release liner with an adhesive layer disposed thereon, the adhesive layer including a plurality of stripes of a first pressure-sensitive adhesive and of a second pressure-sensitive adhesive, arranged in a generally alternating pattern. The first pressure-sensitive adhesive is a silicone-based pressure-sensitive adhesive that includes a silicone block copolymer elastomer comprising hard segments that each comprise at least one polar moiety, and the second pressure-sensitive adhesive is an organic polymeric pressure-sensitive adhesive.
Abstract:
An alternating adhesive tape apparatus is described. The device is equipped with alternating sections or segments, an adhesive section and a non-adhesive section. An intermediary section, referred to as a cut-target section, is disposed within the non-adhesive sections. The cut-target section is configured to act as a guideline for cutting the tape for use by the user, and alerting the user of the location of the adhesive sections of the tape visibly. The cut-target sections, as non-adhesive sections of the apparatus, are preferably colored to indicate which portions are not equipped with adhesive, and provide a guide for cutting. The non-adhesive sections are configured to act as a tab or release-tab for the tape after the tape has been cut in or around the cut-target section, releasing the segment from the roll or strip containing the remainder of the adhesive tape apparatus.
Abstract:
An adhesive film, a method for preparing an adhesive film, and an organic electronic device are provided. According to the adhesive film in exemplary embodiments of the present invention, fluidity of an adhesive can be controlled in the case of applying the adhesive between objects to be subsequently adhered to each other and then thermal-compressing by including an adhesive layer with cured side faces contacting with the outside. The adhesive film is used, for example for assembling a panel and the like, and thereby a defect rate at the time of assembling a panel and the like can be reduced and excellent work characteristics can be provided. In addition, before being applied to a panel or the like, a moisture absorbent included inside an adhesive layer of an adhesive film can be protected from external moisture or the like, thereby being easily stored, and also when it is applied to a product, reliability of life span, and the like can be secured.
