Provided are a film and a water stopping tape that realize long-lasting water stopping properties. The film includes an outermost layer that contains a water-absorbent polymer and a fiber assembly and a substrate layer in this order, in which a degree of out-of-plane swelling of the outermost layer is higher than a degree of in-plane swelling of the outermost layer, and the water stopping tape includes the film.

A blow-molded bottle for a carbonated beverage includes a threaded mouth, a cylindrical side wall, a bottom, and a standard fill capacity of 37.5 mL to 105 mL. The bottle is blow-molded from a laminated preform including an outer layer formed from polyethylene terephthalate, an intermediate gas barrier layer formed from a polyamide comprising a dicarboxylic acid component and a diamine component comprising m-xylylenediamine, and an inner layer comprising polyethylene terephthalate. The laminated preform may weigh from about 4 to 16 grams. The polyamide layer provides the bottle with excellent resistance to carbon dioxide, hydrogen, and nitrogen transmission and prevents the degradation of nutrients and flavors.

Disclosed is a glass-based flexible cover window with improved strength including a planar portion formed so as to correspond to a planar region of a flexible display and a folding portion formed so as to be connected to the planar portion, the folding portion being formed so as to correspond to a folding region of the flexible display, wherein the flexible cover window includes a glass substrate, an adhesive buffer layer formed on the glass substrate, a protective film layer formed on the adhesive buffer layer, and a hard coating layer formed on the protective film layer. The protective film layer is formed on the glass substrate, whereby strength and folding characteristics of the flexible cover window are improved, and inherent texture of glass is maintained while the overall thickness of the flexible cover window is reduced, and therefore aesthetics of the flexible cover window are improved.

Described are improved dental materials and appliances made therefrom that have a range of flexibility and strength and exhibit improved comfort and effectiveness in orthodontic and other treatment.

A decorative print member and a display device including the decorative print member are provided. The decorative print member includes a base layer, a first decorative print pattern disposed on the base layer, and a shielding layer disposed over the first decorative print pattern. The first decorative print pattern includes a first decorative print layer disposed on the base layer, and a second decorative print layer disposed on the first decorative print layer. The shielding layer covers upper and side surfaces of the second decorative print layer, and a side surface of the first decorative print layer protrudes outwardly from the side surface of the second decorative print layer and a side surface of the shielding layer.

A method for producing a multilayer member having a first member containing a crystallizable thermoplastic resin, an adhesion layer, and a second member includes performing a dry treatment on a surface of the first member containing a crystallizable thermoplastic resin so as to satisfy conditions A and B, applying an adhesive to the surface of the first member to form an adhesive layer on the surface, and adhering the second member to the adhesive layer. (A) The ultimate temperature of the first member is lower than the peak temperature of endothermic peak obtained by DSC of the crystallizable thermoplastic resin. (B) The high temperature holding time of the first member is less than 3.0 seconds, which is when the first member is continuously held at a temperature not lower than a temperature at the starting point of the endothermic peak obtained by DSC of the crystallizable thermoplastic resin.

The invention comprises a peelable membrane for resealably closing a metal end comprising an outer layer, a tacky layer, and a heat seal layer. The heat seal layer is permanently sealed to the metal end to cover at least one opening in the metal end. The tacky layer causes the peelable membrane to be resealable onto the metal end.
