Adding materials (saturant) to the backing for improvement of physical properties and resistance to various deleterious environments.
An adhesive joint that is accomplished by coating both adhered surfaces, and bringing them under pressure; an elastomeric adhesive (cohesive) used on envelope flaps, box closures, etc., whereby the adhesive film will bond only to itself.
The time required, under specified test conditions (surface area, weight load), to slide a standard area of pressure sensitive tape from a standard flat surface in a direction parallel to the surface.
The force required to separate a bond by shear force after immersion in a typical varnish solvent under designated conditions.
A tape to which a pressure sensitive adhesive is applied to only one side of the backing.
When the tape tears or breaks into small pieces, either on unwind or on removal from a surface.
The force required to remove a unit width of pressure sensitive tape from a standard panel after it has been in contact with a release liner for a given period of time. This must be compared with the adhesion of the same tape that has not been in contact with the release liner to determine the degree of loss of adhesion.
The measure of surface tension in dynes. The lower the surface energy of a substrate, the more difficult it becomes for an adhesive or coating to wet out that surface.
Any method of treating a polyolefin so as to alter the surface and render it receptive to inks, paints, lacquers, and adhesives, such as chemical, flame and electronic oxidation.
The property of a pressure sensitive adhesive that allows it to adhere to a surface under very slight pressure. It is determined by the ability of the adhesive to wet quickly the surface it contacts.
The force required to propagate a tear in a tape in a given direction after the tear has been initiated.
A sideways sliding of the tape layers, one over another, such that the roll looks like a funnel or a telescope, usually occurring over a period of time.
The force required to break a unit width of tape by controlled pulling on opposite ends of the piece.
The perpendicular distance from one surface of either a tape, backing, or adhesive to the other, usually expressed in mils, thousanths of an inch, or millimeters. This is usually measured under controlled slight pressure with a special gauge.
The force required to remove tape from a roll under prescribed conditions.
The weight of water transmitted through a controlled area of tape under a specified time and conditions.
The weight of water vapor allowed through a controlled area of tape within a specified time period and under allowed conditions.
The ability of an elastometric adhesive, coating, or sealer acting as an insulator to withstand the effects of high voltage discharge.
Rotary Die Cutting – the process of using a cylindrical engraved hardened steel tool to cut materials at high speeds and close-tolerance cutting.Many layers of materials can be cut at one time, using different materials and cutting dies in registration to produce your most complex parts.
