An organic/inorganic composite separator includes (a) a polyolefin porous substrate having pores; and (b) a porous active layer containing a mixture of inorganic particles and a binder polymer, with which at least one surface of the polyolefin porous substrate is coated, wherein the porous active layer has a peeling force of 5 gf/cm or above, and a thermal shrinkage of the separator after being left alone at 150° C. for 1 hour is 50% or below in a machine direction (MD) or in a transverse direction (TD). This organic/inorganic composite separator solves the problem that inorganic particles in the porous active layer formed on the porous substrate are extracted during an assembly process of an electrochemical device, and also it may prevent an electric short circuit between cathode and anode even when the electrochemical device is overheated.

The present invention relates to a pressure sensitive adhesive composition. The present invention may effectively provide a pressure sensitive adhesive where peel forces for both sides are different and an modulus differs along the thickness direction. By applying the pressure sensitive adhesive as above, the present invention may provide, for example, an optical element, such as a polarizing plate, which can effectively inhibit light leakage and shows excellent durability, while being formed to have a thin thickness as well.

A wafer-processing tape, which has an adhesive layer (1) and a removable adhesive layer (2) formed on a surface of a base film (3), and which has an area where B>A, and an area where A>B, in which a peeling force between the base film (3) and the adhesive layer (1) is designated as A, and peeling forces between a target to be bonded (4) and the adhesive layer (1) and between a target to be bonded (5) and the removable adhesive layer (2) are designated as B, wherein the adhesive layer (1) is transferred onto the chip side during pickup in the area where B>A, and the removable adhesive layer (2) is not transferred onto the target to be bonded (5) in the area where A>B during peeling off the tape.

A thin sheet (20) disposed on a carrier (10) via a surface modification layer (30) to form an article (2), wherein the article may be subjected to high temperature processing, as in FEOL semiconductor processing, not outgas and have the thin sheet maintained on the carrier without separation therefrom during the processing, yet be separated therefrom upon room temperature peeling force that leaves the thinner one of the thin sheet and carrier intact. Interposers (56) having arrays (50) of vias (60) may be formed on the thin sheet, and devices (66) formed on the interposers. Alternatively, the thin sheet may be a substrate on which semiconductor circuits are formed during FEOL processing.

A container for condiments includes a container portion having generally planar bottom, a generally parallel flange, and defining a cavity having a discharge spout adjacent the parallel flange. The container further includes a generally planar cover portion fashioned from a material more flexible that the material of the container portion and secured to the flange by an adhesive. The container preferably includes a weakened region transversely aligned with the spout but not having fluid communication therewith. Moreover, the container preferably includes a peel initiating structure aligned with the spout but spaced therefrom effective to reduce the peeling force required to separate the cover portion from the container portion.

A tamper indicating device. A preferred embodiment of the invention provides a backing having a first side and a second side, wherein the backing comprises a first phase and a second phase, wherein the backing has a first level of light diffusion, and when a peeling force is applied to the backing, the backing fractures or internally delaminates and has a second level of light diffusion that is a higher level of light diffusion than the first level of light diffusion; a flood coat applied to the second side of the backing, the flood coat defining a window therein; and a mask applied to the tamper indicating device, the mask being in partial or whole registration with the window in the flood coat.

The present invention relates to improved nasal dilators that prevent the outer wall of tissue of nasal passages of a nose from drawing in during breathing. The improved nasal dilator has a resilient element, or “spring,” made up of a plurality of small filaments for keeping the nasal passages from drawing in while breathing. The filaments may be a variety of shapes and sizes and may run both along the length of the nasal dilator and at a variety of different angles relative to the length of the nasal dilator. The filaments further allow the nasal dilator of the present invention to be removed from the nose in a “top-to-bottom” fashion. The top-to-bottom peel method allows a greater peel angle and so results in less peel force being transferred to the skin of the use.

The invention provides a peelable glue coating composition and a peelable glue coating as well as a preparation method and an application of the peelable glue coating. The peelable glue coating composition comprises the following components in parts by weight: 80-120 parts of an acrylate type oligomer, 8-20 parts of a dilutive monomer, 0.1-1.5 parts of a peeling force modifying agent, 2-12 parts of a triggering agent and 30-50 parts of an organic solvent. The peelable glue coating composition is relatively high in transparency and relatively high in light transmittance and relatively low in haze after film formation. Meanwhile, a coating formed by curing the peelable glue coating composition is relatively high in high temperature resistance and relatively high in peelability. By the high temperature resistance, the coating is good in adhesion property on the surface of a functional hardened layer, and the problems of air bubbles and warping can be effectively improved. By the peelability, the problem of glue layer residues caused during peeling of the coating can be reduced.
