    Abstract: A stretch releasing adhesive article for removably adhesively bonding an object to a surface includes a stretch release adhesive strip and a secondary release member. The stretch release adhesive strip includes a first adhesive end portion having oppositely facing major surfaces arranged to adhesively bond with the object and the surface and includes a non-adhesive tab portion. The secondary release member includes oppositely facing adhesive major surfaces having temporary or repositionable adhesive which allows the adhesive article to be repositioned on the surface and object prior to adhesively bonding the stretch release adhesive strip to the surface and object. The adhesive strength of the secondary release member is sufficient to maintain the secondary release member in adhesive contact with the object and surface when the stretch release adhesive strip is stretched during the removal process. After the stretch release adhesive strip is removed from the object and surface, the secondary release member can be removed from the surface by gently peeling or twisting the secondary release member from the surface.

    Abstract: A tape laminate comprising an internally separable layer having first and second opposite major anchor surfaces, which separable layer has an internal static shear strength in a direction parallel to its anchor surfaces that allows it to support a significant weight (e.g., at least 6 pounds per square inch), and has an internal dynamic tensile strength in a direction generally normal to its anchor surfaces of no greater than 40 pounds per square inch. The major anchor surfaces of the separable layer are bonded to the opposed surfaces of objects (which bonding can be done with strips of stretch release adhesive) so that the laminate can support one object from the other against a static force generally parallel to said anchor surfaces of at least 6 pounds per square inch, whereas the separable layer can be internally separated by a dynamic separating force normal to said anchor surfaces of no greater than about 40 pounds per square inch to separate the objects.

    Abstract: Double-sided stretchable adhesive tapes are described for use in conventional applications, particularly including the mounting or joining of an object to another surface. An improvement lies within the ability to control the timing of the debonding of both surfaces so that one adhesive surface releases before the other. The earlier release can be either on the object side or the surface side, depending on the desired effect. The present invention is applicable to all stretchable tape constructions including the use of plastic backing materials and/or elastic backing materials and allows such an object to be removed without risking substantial snap-back of the adhesive tape or catapulting of the object. The aforementioned advantages can be achieved by a double-sided adhesive tape having a stretchable backing layer, plastic or elastic, and having a lower-adhesion or non-adhesive portion of one adhesive surface, so that a corresponding greater adhesion adhesive portion of the other side remains more aggressively adhered to a surface during stretch removal while the portion of the one adhesive surface is less aggressively adhered or completely released from its surface. A non-adhesive portion may be adhesive-free, or may be an adhesive layer portion which is rendered non-adhesive. A lower-adhesion portion may comprise a low adhesion material, i.e., a weaker adhesive, or may be rendered lower in adhesion by a treatment or coating.

    Abstract translation: 双面可伸缩胶带被描述用于常规应用，特别是包括将物体安装或接合到另一表面。 改进在于控制两个表面的脱粘时间的能力，使得一个粘合剂表面在另一个之前释放。 取决于所需的效果，较早的释放可以在物体侧或表面侧。 本发明可应用于所有可拉伸带结构，包括使用塑料背衬材料和/或弹性背衬材料，并且允许这样的物体被去除，而不会发生粘合带的大量卡扣或物体的弹射。 上述优点可以通过具有可塑性或弹性的可拉伸背衬层并且具有一个粘合剂表面的较低粘合或非粘合部分的双面胶带来实现，使得另一个粘合剂相应的较大粘附粘合剂部分 在拉伸去除期间侧面保持更积极地附着在表面上，而一个粘合剂表面的部分较不积极地粘附或完全从其表面释放。 非粘合部分可以是无粘合剂的，或者可以是不粘合的粘合剂层部分。 较低粘合部分可以包括低粘合性材料，即较弱的粘合剂，或者可以通过处理或涂层使粘合性降低。

    Abstract: A removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150% with less than about 50% elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at least one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by simply stretching it in a direction substantially parallel, i.e. less than about 35.degree., to the surface of the substrate.

    Abstract translation: 一种可移除的胶带，包括高度可延展且基本上无弹性的背衬和一层压敏粘合剂。 背衬具有高拉伸强度，纵向伸长率至少为约150％，拉伸后弹性回复率小于约50％。 粘合剂可以是通常粘性和压敏粘合剂并且涂覆在膜背衬的至少一个表面上。 粘合剂优选是高度可延展的，在拉伸期间不与背衬分离，并且具有比对任何合适基底的粘附更高的内聚力。 在施加到基板上之后，本发明的粘合带变得牢固地结合，但是可以容易地移除，而不会通过简单地将基板平行地（即，小于约35°）的方向拉伸到基板的表面而不损坏基板 。
