摘要： A cavity-containing polyester film is disclosed, including a layer (layer A) which has therein cavities, and layers (layers B) which each include a polyester resin containing inorganic particles and which are laminated, respectively, over both surfaces of the layer A. The layer A includes a composition including a polyester resin and a polypropylene resin. The polypropylene resin satisfies requirements of: (1) the melt flow rate (MFR) ranges from 1.0 to 10 g/10-minutes (at a temperature of 230° C. under a load of 2.16 kg); (2) the deflection temperature is 85° C. or higher under load (at a bending stress of 0.45 MPa); and (3) the weight-average molecular weight Mw ranges from 200,000 to 450,000 (measured by gel permeation chromatography (GPC)); and the molecular weight distribution ranges from 2 to 6 (being represented as the ratio of the weight-average molecular weight Mw to the number-average molecular weight Mn of the polypropylene resin (Mw/Mn)).

摘要： A squeezable, white polypropylene film is disclosed having a novel balance of conformability, stiffness, modulus, opacity, and whiteness. The film includes an ABCBA structure having a core layer of polypropylene resin with an elastomeric copolymer and a cavitating agent. Two intermediate layers of polypropylene resin are present on either side, the intermediate layers optionally including an elastomeric copolymer and a pigmenting agent. Two polymer skin layers surround the two intermediate layers. The resins are co-extruded into a biaxially oriented film having a thickness between 40 to 70 pm for use in pressure-sensitive labeling applications.

摘要： An adaptive textile that includes a plurality of a first fiber having a first expansion coefficient and a plurality of a second fiber having a second expansion coefficient. There is a difference between the expansion coefficient of the first fiber and the expansion coefficient of the second fiber; at least one of the first or second fibers is a twisted coil actuator; and linear displacement of the twisted coil actuator causes the adaptive textile to bend.

摘要： The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer of paper, paperboard or other cellulose-based material, an innermost, heat sealable and liquid-tight layer of a thermoplastic polymer, the innermost polymer layer intended to be in direct contact with the packaged food product, a barrier layer laminated between the bulk layer and the innermost layer. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.
