Re-closure Tape Application on Packaging Machine

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 roll. 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.

METHOD FOR PREPARING STRUCTURED ADHESIVE ARTICLES
20190023950 · 2019-01-24 ·

Methods of forming laminating adhesive articles include providing a multi-layer article, and a tool with a structured surface. The multi-layer articles include a substrate, an adhesive layer, and a liner. The multi-layer article is placed between the structured surface of the tool and a support surface that is hard and the tool is embossed against the liner by applying pressure or pressure/heat. The embossing causes the tool structures to distort the liner and the adhesive layer, and causes permanent topological changes in a portion of the adhesive layer, but does not distort the substrate. The distortion in the liner is retained upon release of the applied pressure. The portions of topologically changed adhesive can form convex structures that are permanent. Upon removal of the liner from the adhesive layer, the concave structures on the adhesive layer are unstable, but the convex structures are stable.

ADHESIVE MEMBER TO BE ADHESIVELY FIXED THROUGH PRESSURE

Provided is an adhesive member to be adhesively fixed through pressure which has both position adjustability and adhesiveness and is capable of producing a sufficient adhesive strength in addition to the position adjustability. The adhesive member comprises a support, a pressure-sensitive adhesive layer provided on one surface of the support, and a plurality of protrusion elements arranged, in spaced-apart relation to each other, on a principal surface of the pressure-sensitive adhesive layer on a side opposite to the support. Each of the protrusion elements is composed of an aggregation of a plurality of cohesive particles, wherein the adhesive member has a frictional force of 0.4 N/cm.sup.2 or less, with respect to a stainless steel plate serving as an adherend, as measured when the protrusion elements are in contact with a surface of the adherend, and a shear adhesive strength of 45 N/cm.sup.2 or more.
