The present invention relates to a method for packaging fruits and vegetables by means of a film endowed with specific permeability and light transmittance properties.

Protective shields configured to prevent projection against projectiles, such as during excavating and/or mining operations, are provided. The protective shields include a base layer comprising one or more transparent polycarbonate layers, a sacrificial polycarbonate layer comprising a transparent polycarbonate, and an air gap positioned directly between at least a portion of the base layer and the sacrificial polycarbonate layer. The sacrificial polycarbonate layer is directly or indirectly attached to the base layer in a manner to provide the air gap positioned between the base layer and the sacrificial polycarbonate layer.

A laminate, containing two or more polyolefin resin layers, wherein at least one polyolefin resin layer (A) contains a cellulose fiber including a cellulose fiber having a fiber length of 0.3 mm or more dispersed in the layer; a content of the cellulose fiber in the polyolefin resin layer (A) is 1% by mass or more and less than 60% by mass; and wherein a polyolefin resin layer (B) different from the polyolefin resin layer (A) is laminated in contact with the polyolefin resin layer (A).

The disclosed technology relates to a battery pack assembly that includes multiple battery cells. In some aspects, each cell is bonded to a first surface of a first liner (e.g., a cosmetic liner) via a first adhesive. The first adhesive is configured to provide a first adhesive force between each of the battery cells and the first surface before exposure to ultraviolet (UV) light and a second adhesive force after exposure to UV light, and wherein the second adhesive force is less than the first adhesive force. A battery pallet and method of manufacturing are also provided.

A lidding film comprising oriented polyethylene bonded to non-oriented polyethylene is disclosed. The oriented polyethylene may comprise a plurality of layers and the non-oriented polyethylene may comprise a plurality of layers, wherein the oriented polyethylene is bonded to the non-oriented polyethylene by extrusion coating or by a laminating adhesive. The oriented polyethylene comprises machine direction oriented polyethylene (MDO PE) or biaxially oriented polyethylene (BOPE). The lidding film may comprise from 1 to 15 wt. % of a polymer other than polyethylene, preferably the lidding film comprises no more than 5 wt. % of a polymer other than polyethylene. Also disclosed is a sealed container comprising a lidding film according to the invention and a polymer tray wherein the lidding film is heat sealed to the top edge of the polymer tray via the non-oriented polyethylene, thereby enclosing a product within a recess defined by the polymer tray. Also disclosed is a method of producing a lidding film.

Abstract: A label (1; 50) for a tyre (100) of vehicle wheels comprises: at least a first layer (4) which is made of an elastomer material which is compatible with the elastomer material of a sidewall (102) of the tyre, an external surface (2) which is intended to remain visible when the label is coupled to the sidewall, a plurality of recesses (10) which are formed at the external surface (2) and which are capable of generally defining at least one portion of information which is set out on the label (1; 50). The elastomer material of which the first layer (4) is made comprises a quantity of a halogenated isobutylene polymer greater than 5 phr.

The invention relates to multilayer polymer structures having at least three layers. These layers include a polar capstock layer other than an acrylic, an olefinic substrate layer, and a tie layer. The tie layer is selected from olefinic acrylate copolymers, a block copolymer of vinyl aromatic monomer with an aliphatic conjugated diene or a derivative thereof, a copolymer of olefin and (meth)acrylic acid partially or fully in the salt form, a high impact polystyrene, and/or a vinyl cyanide-containing compound. Each layer could contain multiple sub-layers. The multilayer structure exhibits excellent structural integrity, excellent surface appearance, high impact strength, high scratch resistance, and excellent resistance to UV rays.

Gypsum panels and methods of making gypsum panels are provided. Methods of making gypsum panels include: depositing a first gypsum slurry onto a first surface of a first fiberglass mat; allowing the first gypsum slurry to set to form at least a portion of a gypsum core; and applying a substantially continuous barrier coating comprising a polymer binder to a second surface, opposite the first surface, of the first fiberglass mat, in an amount of from about 1 lb/MSF to about 40 lb/MSF, such that the substantially continuous barrier coating has an average thickness of from about 1 micron to about 100 microns, wherein the substantially continuous barrier coating eliminates at least 99 percent of pin holes present in the exposed second surface of the first fiberglass mat.

One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.

Uncured composite structures, cured composite structures, and methods of curing uncured composite structures are disclosed herein. The uncured composite structures include a structural layer that includes an uncured structural resin and a surface layer that includes an uncured surface resin. The cured composite structures include a cured structural layer that includes a cured structural resin, a cured surface layer that includes a cured surface resin, and an interface region between the cured surface layer and the cured structural layer. The methods include initially heating the uncured composite structure to an initial temperature to generate a partially cured composite structure. The initially heating is sufficient to gel the uncured surface resin but insufficient to gel the uncured structural resin. The methods also include subsequently heating the partially cured composite structure to a final cure temperature, which is greater than the initial temperature, to generate the cured composite structure.
