Abstract: A fibrous material, method for making the same, and articles comprising the same are shown and described. The fibrous material is a low density material that exhibits high strength properties. In embodiments, the fibrous material has a density of 0.15 g/cm3 or less and a tensile strength of 10 N/inch or greater. The fibrous material may be in the form of a paperboard and is suitable for use in a variety of applications including as a packaging material.

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 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.
