摘要:
An article 10 is provided with an adhesive layer 14 that includes an adhesive, a release layer 12 that is stacked on the adhesive layer 14, and an air layer 16 that is interposed between the adhesive layer 14 and the release layer 12. On a surface 12a of the release layer 12 that opposes the adhesive layer 14, microprotrusions 20 that contact the adhesive layer 14 with tips 20a are provided. The microprotrusions 20 are provided with a wall-shaped portion 22 having a shape that at least partially surrounds the air layer 16 between the adhesive layer 14 and the release layer 12. The wall-shaped portion 22 protects a main portion 14a of the adhesive layer 14 that is adjacent to the air layer 16 from contamination. By selecting a shape, dimensions, and the like of the micro protrusions 20, a release force of the release layer 12 can be adjusted to a desired range.

The aim of the invention is to improve the barrier effect of an adhesive strip for encapsulating electronic arrangements against permeates, in particular water and oxygen. This is achieved by providing a composite system for encapsulating electronic arrangements which comprises at least (a) an adhesive strip containing at least one pressure-sensitive adhesive substance for direct application on a substrate; and (b) at least one release liner which lies directly upon the pressure-sensitive adhesive substance, the surface of the release liner that faces the pressure-sensitive adhesive substance having a surface roughness of less that 100nm, measured as an arithmetic mean S a as per ISO/FDIS 25178-2:2011 of the amounts of at least 10,000 height values of the profile of a partial surface of at least 200µm x 200µm. The invention further relates to a method for producing a release liner with a smooth surface, the use of such a release liner for equipping barrier adhesive strips and the use of an adhesive strip obtained from the composite system as per the invention by removing the liner in order to encapsulate electronic arrangements.

The invention relates to a peelable adhesive strip which is coated with a pressure-sensitive adhesive at least one side. Said adhesive strip is constituted of the following layers: a core layer having an elongation at tear of at least 300%, an external carrier layer having an elongation at tear of not more than 120% and at least some sections of which are connected to the core layer in such a manner that it becomes detached from the core layer when the same is stretched, a first adhesive layer at least some sections of which are applied to the side of the external carrier layer and which is opposite the side connected to the core layer.
摘要:
Das neue Klebeband besteht aus einer biaxial orientierten und transparenten ein- oder mehrschichtigen Trägerfolie aus im wesentlichen Polyolefin, die auf einer Seite mit einer Klebstoff-Schicht versehen ist und auf der anderen Seite mit einer transparenten und im Vergleich zur Trägerfolie dünnen Außenschicht, die im wesentlichen aus einem Polyolefin als Hauptkomponente und 10 bis 40 Gew.-%, bezogen auf die Schicht, von einem anorganischen Weißpigment besteht, wobei die Teilchen des Weißpigmentes besondere Merkmale aufweisen und in einer bestimmten Beziehung zur Dicke der genannten, für die Beschriftung vorgesehenen Außenschicht stehen. Dieses Polyolefin-Klebeband weist eine hohe Transparenz auf, ist gut beschriftbar und ohne irgendwelche Markierungen, hell-dunkel-Unterschiede und dergleichen kopierbar und besitzt auch gute mechanische Eigenschaften. Es stellt demnach ein hervorragendes mending tape auf der Basis von Polyolefinen dar.
