摘要:
A multilayer film suitable for sealing containers such as used for food packaging, and methods of making the film, are described. The film is particularly suitable for sealing containers made from polylactic acid (PLA). The multilayer film includes a) a substrate that includes a polymeric base layer; and b) on the substrate, a heatseal layer containing a PLA homopolymer or copolymer. The heatseal layer further includes dispersed therein an adhesion promoter, or alternatively the substrate further includes the adhesion promoter in a layer on a surface of the polymeric base layer between and adjacent the base layer and the heatseal layer. An antifog agent may also be included in the heatseal layer or on the surface of the heatseal layer opposite the substrate.

Described are antifog films useful for packaging food, and more particularly to antifog films that can be used as lidding films in trays made of amorphous polyester. The films may include at least one base layer or film, such as a polyester film, and a heat seal layer. The antifog layer is coated on the heat seal layer. The heat seal layer allows the antifog coating to more strongly adhere to the antifog film. The heat seal layer may be an amorphous polyester layer.

Provided are compositions comprising an ethylene acid copolymer and a functional ethylene copolymer. The ethylene acid copolymer comprises in-chain polymerized units derived from ethylene and at least one ethylenically unsaturated monocarboxylic acid or derivative thereof. The functional ethylene copolymer comprises in-chain polymerized units derived from ethylene and at least one ethylenically unsaturated dicarboxylic acid or derivative thereof. Optionally, the ethylene acid copolymer or the functional ethylene copolymer further comprises one or more copolymerized alkyl(meth)acrylates. The carboxylic acid functionalities of the ethylene acid copolymer and the functional ethylene copolymer may be at least partially neutralized to form carboxylate anions. Preferred counterions include one or more alkali metal, transition metal, or alkaline earth metal cations. The compositions are useful for fabricating films, sheets and other shaped articles, such as packages.

A shock-absorbable grip is comprised of a sleeve and a sheathing. The sleeve includes a hollow main body for being mounted on a handle of the sporting apparatus and having a front retainer and a rear retainer protuberating respectively at its front and rear ends. The sheathing wraps the main body between the front and rear retainers, having a slope matching face formed at an edge of its one short side, a top side for holding by the user, and a bottom side mounted on an external periphery of the main body. The front retainer has a slope face closely mounted with the slop matching face.

Heat sealable fluoropolymer-containing films and articles. More particularly, heat sealable films, tubes, packages, and other articles formed from a chlorotrifluoroethylene/vinylidene fluoride copolymer containing about 5% to about 25% vinylidene fluoride. The copolymers are capable of being formed into single or multilayer films that are heat sealable using conventional heat sealing methods while maintaining excellent clarity and moisture barrier properties.
