摘要： A propylene polymer-based composite film, a preparation method therefor, and an application thereof are provided. The composite film contains at least two different layers: layer a and layer b layer. Layer a and layer b each contains at least one propylene polymer, and at least one of layer a and layer b contains a propylene impact copolymer. The propylene impact copolymer contains elastic moieties that form dispersed strip-like rubber phases in the composite film. The rubber phases are arranged parallel to each other. The average dimension of transverse axes of the rubber phases is 20-200 nm and the average of aspect ratios is 5-20. The composite film is can be used in the field of packaging materials, especially in battery packaging materials, electronic product packaging materials, or food packaging materials.

摘要： A thermoplastic composite material has an inner layer material and at least one layer of outer layer material. The inner layer material is a core layer that contains fiber bundles, a first thermoplastic resin and a first auxiliary agent; and the at least one layer of outer layer material wraps the core layer and is a resin layer comprising a second thermoplastic resin and an optional second auxiliary agent. The fiber bundles extend continuously from one end of the core layer to the opposite end thereof. The inner layer-outer layer composite structure, can effectively improves the processing performance of the thermoplastic composite material and the lubricity between fibers and resin matrixes during injection molding, and improves the fluidity of the fibers in a resin matrix melt.
