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.

Disclosed in the present invention is a packaging composite material comprising polarizing films, the packaging composite material comprising: a polarizing layer, comprising two or more layers of polarizing film, wherein polarization directions of at least two layers of polarizing film have an included angle which is not 0°. The packaging composite material of the present invention has a simple structure, strong light-blocking properties, a high light-blocking rate, and a broad-spectrum light-blocking effect. Also disclosed in the present invention are the use of the packaging composite material in packaging, and the use of the packaging composite material in a label. When used as packaging or a label, the packaging composite material can extend the shelf life of products which need to be stored in the dark.

A principal film comprising a first polymeric component wherein the principal film has: (1) first and second major faces; (2) a land portion wherein the principal film is capable of thermally-induced self- forming; and (3) one or more modification zones, each comprising a central portion and a rim portion surrounding the central portion and being surrounded by land portion, wherein the average thickness of each rim portion is greater than the average thickness of the land portion surrounding the modification zone, the average thickness of each central portion is less than the average thickness of the land portion surrounding the modification zone and is greater than zero. Also methods for making such films and articles comprising such films.

[PROBLEM] To provide a packaging and a display material which permit printing in distinct fashion by a laser, and which are of high transparency. [SOLUTION MEANS] A display material having at least one layer permitting printing as a result of laser irradiation, the display material being such that the printing occurs due to change in color caused by the laser irradiation in at least one region of said layer; when a digital microscope is used to carry out cross-sectional observation of said printed region and a nonprinted region, a significant difference in at least any one of RGB values indicating color elements is observed; and thickness of said printed region is not less than 5μm but not greater than 200 μm.

A composite stretch film for agricultural use is formed by bonding two stretch films together with an adhesive through hot rolling or UV curing such that primary stretch directions thereof cross each other. The composite stretch film of the present invention is significantly improved not only in transverse and longitudinal tensile strength but also in transverse and longitudinal tear strength. Therefore, it is able to meet the requirements for use in agriculture with a lesser thickness and hence reduce the use cost. In particular, in case of the composite stretch film being made of a polyester material, it further offers the advantages such as high-light transmittance which changes mildly with time, better thermal insulation properties and better humidity-regulating capabilities. In particular, in case of it being made of a degradable polyester materials, it will further offer profoundly significant benefits in terms of energy saving and environmental protection.

Solid state draw a laminated polymer billet containing two or more polymer compositions laminated to one another to prepare an oriented polymer composition.

A feedblock including a first packet creator that forms a first packet including a first plurality of polymeric layers, the first plurality of layers including at least four first individual polymeric layers; and a second packet creator that forms a second packet including a second plurality of polymeric layers, the second plurality of layers including at least four second individual polymeric layers, wherein the first and second packet creators are configured such that, for each packet creator, respective individual polymeric layers of the plurality of polymeric layers are formed at approximately the same time. The feedblock may include a packet combiner that receives and combines the first and second primary packets to form a multilayer stream. In some examples, at least one of the first and second primary packets may be spread in the cross-web direction prior to being combined with one another.
