The present disclosure relates to an optical laminate or a reddening-resistant layer. The present disclosure can provide an optical laminate that does not cause a so-called reddening phenomenon even when driven or maintained under extremely harsh conditions (e.g., very high temperature conditions), or a reddening-resistant layer applied thereto.

An optical laminate or a reddening-resistant layer. The optical laminate does not cause a reddening phenomenon even when driven or maintained under extremely harsh conditions (e.g., very high temperature conditions), or a reddening-resistant layer applied thereto.

A laminate including a first base material layer, a second base material layer, and a sealant layer in this order, wherein all three layers include a polyolefin film; the polyolefin film of the first base material layer or the second base material layer includes an inorganic oxide layer on at least one surface thereof; and each of the first base material layer, the second base material layer, and the sealant layer has a heat shrinkage rate, in a travel direction after heating at 120° C. for 15 minutes, which satisfies the following inequalities: heat shrinkage rate of the second base material layer≤5% (Inequality 1); heat shrinkage rate of the second base material layer≥heat shrinkage rate of the first base material layer (Inequality 2); and, heat shrinkage rate of the second base material layer≥heat shrinkage rate of the sealant layer (Inequality 3). ws

A gas barrier film includes: a substrate mainly composed of polyethylene or polypropylene; a gas barrier layer formed on the substrate; and a cover layer formed on the gas barrier layer; a surface of the substrate on which the gas barrier layer is formed has an element ratio O/C between oxygen and carbon of 0.03 or more.

Disclosed herein are compositions and methods related to a packaging laminate comprising: a first polymeric layer comprising a polypropylene copolymer; and a second polymeric layer comprising a high density polyethylene (HDPE) resin with a coextruded ethyl vinyl alcohol (EVOH) compatibilizer.

A quasi-isotropic reinforced sheet material T formed by integrating a plurality of chopped semi prepreg sheet materials C including a reinforced fiber material and a thermoplastic resin material set in an unimpregnated state such that fiber directions of the reinforced fiber materials are oriented randomly in the two-dimensional direction. The average number of fibers in a thickness direction for materials C ranges is from two to ten and a thickness “t”, relative to the thickness (t.sub.p) in an impregnated state, is in a range of t.sub.p<t≤2×t.sub.p. A layered body M is obtained by bonding and integrating the materials C in a state where fiber directions of the reinforced fiber materials are oriented randomly in a two-dimensional direction and the materials C overlap such that the average number of the materials C in the thickness direction is set in a range from two to ten.

The invention relates to a sheet-like composite including as layers of a layer sequence, in a direction from an external side of the sheet-like composite to an internal side of the sheet-like composite, a) a carrier layer, b) a barrier layer, and c) a polymeric internal layer, where a graph of a differential scanning calorimetry of the polymeric internal layer includes a peak A at a temperature T.sub.A and a peak B at a temperature T.sub.B, where the temperature T.sub.B is more than the temperature T.sub.A, where a width of the peak B is less by at least 3° C. than a width of the peak A. The invention further relates to a container precursor and to a closed container including the sheet-like composite, and also to a process by which the sheet-like composite is obtainable, and to a use of the sheet-like composite.

There are provided rolls comprising an air and water barrier article having opposing first and second major surfaces, a pressure sensitive adhesive disposed on at least the first major surface of the article, and a liner having a first major surface that contacts the opposing second major surface of the article, and at least two adhesion modifying zones disposed between the second major surface of the article and the first major surface of the liner, wherein both of a first and second adhesion modifying zones contact the first major surface of the liner, and wherein the pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll. There are also provided films made using these air and water barrier articles and building envelopes made using such films.

A solar reactive mulch film comprising one or more layers of heat shrink material pre-strained at a predetermined temperature and tension. Immediately cooling the pre-strained layers retains molecular deformation stresses in the material which facilitate shrinkage but not expansion on exposure to solar radiation. The mulch film adapted to be laid over longitudinal growing beds and held tautly by burying its side edges in soil. Exposure of uncovered portions of film to solar radiation causes shrinkage in one or more directions whereby in combination with the weight of the soil holding it down, maintains tautness of the mulch over a growing period. Methods of manufacture and use of the same.
