摘要:
A biaxially oriented laminate film including a core layer including a blend of crystalline polylactic acid polymer and a metal salt phosphorus-containing compound nucleating agent which is biaxially oriented at low transverse direction orientation temperatures to impart a degree of cavitation around the metal salt phosphorus-containing metal such that a white opaque cavitated appearance and a lower film density and improved mechanical properties are obtained. The laminate film could further have additional layers such as a heat sealable layer disposed on one side of said core layer including an amorphous polylactic acid resin and/or a polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.

A patient interface device and cushion for the device are respectively disclosed, for preferred CPAP and BiPAP breathing masks. The cushion has a composite structure with an open rounded polygonal profile defining a mask side layer and a slip-resistant fibrous patient side layer, with an intermediate barrier layer positioned between the first and second layers. The layers are integrally bonded together into a three-dimensional conformation defining a J-shaped cross section and an inboard patient side curl opening into an air chamber juxtaposed with one or more of the patient's airways. The body exhibits flexibility between about 4 and about 10 Taber Stiffness Units. Method and apparatus for making the cushion are further described.
摘要:
It is an object to provide a composite in which the adhesion between a sheet layer and a curable resin layer or a film layer is high, and which has high strength and high transparency. The present invention provides a composite wherein a curable resin layer or a film layer is laminated on the one or both surfaces of the sheet layer with a covering layer interposed therebetween, the sheet layer containing fine fibers with an average fiber width of 2 to 1000 nm.

Methods for using the permeable membrane sheet (1) in construction are also provided.
摘要:
Wrapper-type packaging composed of a flexible plastics sheet material in the form of a sack or bag having a front wall and a rear wall, which are located opposite one another and are sealed by a side sealing seam to form a flexible sack-like or bag-like tube, of which the opening is covered by a closure flap which is formed by a projection of the rear wall and is folded onto the front wall at least as far as the opening and is closed by longitudinal sealing and, possibly, transverse sealing or adhesive bonding, the opening having an opening aid, wherein the flexible plastics sheet material is oriented at least uniaxially and optionally is embossed and has a tear-propagation resistance in the machine direction which differs by at least 30% from the tear propagation resistance in the direction transverse to the machine direction.

Provided are a sealing tape that can prevent tape width misalignment, air bubble inclusion, and creasing even when the sealing tape is affixed in a folded state, a phosphor sheet using the same, a lighting device, a liquid-crystal display, a method for manufacturing a phosphor sheet, and a sealing method. The sealing tape (10) includes an adhesive layer (11), a gas barrier layer (12), a bonding layer (13), and a support film layer (14) laminated in stated order, and has an incision (15) into the support film layer (14) in a thickness direction. The incision (15) is located substantially centrally in a width direction and extends in a longitudinal direction. Accordingly, tape width misalignment, air bubble inclusion, and creasing can be prevented even when the sealing tape is affixed in a folded state.

An environmentally friendly container with bioplastic shell and glass lining includes a shell defining a hollow body of the container; a wall of the shell that includes a bioplastic resin; and a lining that includes a liquid glass and coats a surface of the wall. Embodiments may include an opening at an end of the shell; a cap that includes the bioplastic resin of the shell; and a cap lining on an inner surface of the cap, the cap lining forming a closure with the lining of the wall so that the container provides a sealed cavity; wherein the lining is on an inner surface of the wall of the shell, thereby fully lining an interior cavity of the container with glass; and the bioplastic resin includes PLA, PLLA, PDLA, PHA, PCL, or PBT.
摘要:
The present invention relates to a waterproof board and its manufacturing method, belongs to the technical field of floorboard and wallboards. The waterproof board includes waterproof layer and wear-resistant layer and the groove and ten on arranged on both side of said board respectively. Said wear-resistant layer is affixed onto said waterproof layer and said waterproof layer is made of the extrusion materials mainly including the resin and bamboo powder. The density of said waterproof layer is 0.60 kg/cm3-0.95 kg/cm3. The board of present invention is featured of high strength, good tensile strength, not easy to break; low water absorption rate, good waterproof performance; strong stability, less susceptible to deform due to changes in temperature or water immersion; light weight, more comfortable tactility, and further decreasing the material and transportation costs.
