A method of manufacturing a microfluidic system or microfluidic device having at least one channel includes providing a base sheet, providing a deformable intermediate layer, providing a cover film, and laminating the base sheet, the intermediate layer and the cover film so that a back surface of the intermediate layer is attached to a front surface of the base sheet and a back surface of the cover film is attached to a front surface of the intermediate layer opposite to the back surface thereof, thereby forming a laminate comprising the base sheet, the intermediate layer and the cover film. Further, the method includes applying pressure to the front surface of the intermediate layer through the cover film so as to deform the intermediate layer, thereby forming the at least one channel. The invention also relates to a microfluidic system or microfluidic device) manufactured by this method.

Disclosed are an undercover for vehicles with high elasticity and rigidity and a method of manufacturing the same. The undercover for vehicles with high elasticity and rigidity may include a needle-punched nonwoven fabric having a multi-layer structure of felt layers including a first PET fiber and a low-melting-point PET fiber, and each of the felt layers may have improved tensile strength and have optimized fiber alignment, to thereby improve the binding between fibers, mechanical rigidity and elasticity, as well as to reduce the weight of components, improve durability and secure harmlessness and inline workability.

Provided are a multilayer film having excellent gas permeability and excellent handling properties and hence is suited for forming a cell culture container, and a cell culture container formed by using the same. A multilayer film used for forming a cell culture container, comprising: a base material composed of a polyethylene-based resin having a density of 0.87 g/cm.sup.3 to 0.90 g/cm.sup.3; and an inner layer composed of a polyethylene-based resin having a density of 0.896 g/cm.sup.3 to 0.93 g/cm.sup.3 and forming a cell culture icy surface. A cell culture container is formed by using this multilayer film.

Provided are vacuum-insulated articles that comprise an evacuated space disposed between first and second walls and a reflective material disposed within the evacuated space. Also provided are methods of fabricating such articles.

Two-component solventless polyurethane adhesive compositions comprising an isocyanate component and an isocyanate-reactive are disclosed, the compositions comprising an isocyanate component comprising an isocyanate-terminated prepolymer and an isocyanate-reactive component comprising a hydroxy-terminated polyurethane resin, a polyether polyol, a phosphate ester adhesion promoter, and, optionally, a bio-based polyol. Methods for forming laminate structures are also disclosed, the methods comprising forming an adhesive composition by mixing an isocyanate adhesive component comprising an isocyanate-terminated prepolymer and an isocyanate-reactive adhesive component comprising a hydroxy-terminated polyurethane resin, a polyether polyol, a phosphate ester adhesion promoter, and optionally, a bio-based polyol, applying the adhesive composition to a surface of a first substrate, and bringing a surface of a second substrate into contact with the adhesive composition on the surface of the first substrate, thereby forming the laminate structure. Laminate structures are also disclosed.

The present utility model provides an easy-to-clean protective film, which belongs to the technical field of protective films for vehicles and other vehicles, and can solve the problems that lasting scratches are easily caused to the existing vehicle coatings and surface stains are not easy to clean. The easy-to-clean protective film provided by the present utility model comprises a polyvinyl chloride (PVC) bottom film and an easy-to-clean layer consisting of silicon dioxide particles, wherein the water contact angle of the easy-to-clean layer is small and thus the adhesive force of dust and oil stains can be reduced. After the surface of the easy-to-clean layer is contaminated by dust and oil stains, the dust and oil stains can be easily cleaned with a simple cleaning. The easy-to-clean protective film provided by the present utility model is suitable for use as protective coatings of various substrates, especially for attachment to the body surfaces of vehicles such as automobiles.
