US Patent:

50893203, Feb 18, 1992

Filed:

Nov 9, 1990

Appl. No.:

7/603760

Inventors:

Steven J. Straus - Concord CA
Edward J. Zuscik - Oakland CA
William B. Bower - Palo Alto CA
Apostol Yanidis - Berkeley CA

Assignee:

James River II, Inc. - Cincinnati OH

International Classification:

B32B 1900

US Classification:

428216

Abstract:

A machinable flexible packaging material capable of forming a seal that is reclosable at ambient temperature is made by applying a tacky adhesive and a thin skin layer onto a substrate, such as polyester film. Being thin, the skin layer fractures when the seal is opened, thereby allowing the adhesive to form a resealable interface at the seal area. However, since the adhesive is encapsulated in the material initially, the material may be used like other packaging materials in form, fill and seal machines.

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.
