The invention relates to a shrink face film and a shrink label comprising said face film. According to an embodiment the shrink face film includes a first skin layer and a second skin layer comprising propylene terpolymer(s) between 1 and 99 wt. %, and a core layer comprising random copolymer(s) of propylene or propylene terpolymer(s), and a modifier, which is at least one of the following: olefinic plastomer, olefinic elastomer and ethylene-octene block copolymer. The invention further relates to a method for providing a shrink face film and a method for labelling of an item with a shrink label comprising said face film.

Wrinkling of a contoured composite laminate part during forming to contour is reduced by using laminate plies having off-angle reinforcing fibers that provide the part with primary axial strength along a major axis of loading.

Disclosed are recyclable flexible package and a method of recycling such packages. The flexible package includes a hollow body defining an interior chamber for holding an oxygen sensitive product. The body is formed of a laminated film formed of two layers of a single polymer material, e.g., polyethylene, and at least one interposed barrier layer, e.g., polyvinyl alcohol, that is resistant to the passage of oxygen therethrough and which is water-soluble. The single polymer constitutes at least 95% by weight of the laminated film, whereupon the package is suitable for recycling without requiring separation of the materials thereof by shredding the laminated film and subjecting those pieces to an aqueous wash to dissolve the barrier layer.

The invention relates to a system and to a method for producing a rotor-blade spar cap with pultruded rods made of a fiber-reinforced material. According to the invention, the system includes at least one retaining apparatus for rotatably mounting at least one rod-layer roll with a rolled-up layer of pultruded rods arranged one beside the other, and a laminating mold for receiving layers of pultruded rods. The system further includes at least one guiding apparatus and additionally at least one trimming apparatus. The guiding apparatus is designed to guide onto the laminating mold a layer of pultruded rods which has been unrolled from a rod-layer roll. And, the trimming apparatus, for trimming the layers of pultruded rods, has a sawing apparatus and/or a milling apparatus.

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.

The present invention is directed to packages having a thermoformed product receiving cavity for containing the product formed from a first flexible heat shrinkable film and a lidding film covering the thermoformed product receiving cavity formed from a second flexible non-heat shrinkable film. The present invention also includes an opening tab on each of the two flexible films which are aligned with each other such that each of the tabs has a sufficient surface area facing the other tab but not adhered to it to render each tab readily manually graspable. The opening tab of the first flexible heat shrinkable film includes a distal portion which is curled to improve its graspability.

A decorative film that can handle various adherend shapes and application methods and has a visual effect that changes according to viewing angle. The decorative film of one embodiment includes a substrate layer, a photoluminescent layer that is adjacent to the substrate layer and has an unevenly-shaped surface, a transparent resin layer adjacent to the photoluminescent layer, and an outermost layer. A storage elastic modulus of at least the substrate layer or the transparent resin layer is 1×10.sup.6 Pa to 1.5×10.sup.8 Pa in a temperature range of 100° C. to 150° C. when measured under conditions of a frequency of 10 Hz and a shearing mode.

A supported elastomeric foam (100) includes an elastomeric matrix (102) formed of an elastomer and including a reinforcement region (104) and a foamed region (106). The foamed region includes gas filled cells (108) in the elastomer, and the reinforcement region includes a porous layer (204) having an interconnected network of pores at least partially imbibed with the elastomer. The foam can include an adhesive at a surface of the foam. A compressible seal (802) including a compressible body, which can be elastomeric foam, can also include a pattern of discontinuous adhesive regions about which the compressible body can deform to form a sea. The supported elastomeric foam can form a gas tight seal in an interface when placed under minimal compression.

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.

A cleaning article. The cleaning article has a laminate construction. The cleaning article comprises a sheet and a hydrophilic gather strip element joined together at plural bonds. The gather strip element has plural layers superimposed upon one another, providing strips extending outwardly from the bonds. Different layers are differentially bonded, to provide a construction which allows the strips to advantageously present a dynamically changing area to the target surface during cleaning, under normal usage conditions. By changing the surface area, more liquids, and associated debris, can be cleaned from the target surface.
