な風合いのポリオレフィンフィルムに関する。Detailed Description of the Invention [Industrial Field of Application] The present invention provides a polyolefin film containing 2 to 40% by weight of crosslinked polymer particles with an average particle diameter of 3 to 50 μm and having excellent flexibility and a soft texture. Regarding.

織布、容器その他の成形品として広く使用されている。[Prior Art and Problems to be Solved by the Invention] Polyolefins, particularly polyethylene and polypropylene, have excellent physical and chemical properties and are therefore widely used in films, nonwoven fabrics, containers, and other molded products.

サ音がするといった問題が知られている。However, contrary to its excellent properties, films in particular have poor blocking resistance and slip properties, molded products have a sticky feel that is undesirable in terms of texture, and are easily charged with electricity, resulting in poor workability. It is known to have problems such as poor matting properties and rustling noise.

し性もないものであった。In order to solve these problems, a method has been proposed in which fine particles are contained in polyolefin to impart appropriate roughness to the surface of the molded article, thereby improving these problems. For example, polymer particles that do not have a melting point are mixed with a polypropylene resin, melted and extruded, and then stretched into a film (Japanese Patent Publication No. 50-36262, Japanese Patent Application Laid-open No. 57-64522).
Although the anti-blocking properties and slip properties were improved to some extent, the film itself still had a sagging feeling and rustling sound, was easily charged with electricity, and lacked matte properties.

No. 1-34865) had a paper-like texture, and although the hiding performance and printability were improved, the film itself had a feeling of sagging and rustling, and lacked flexibility.

完成するに到った。The present inventors solved the above problems while retaining the inherent properties of polyolefin films, and as a result of researching polyolefin films that have a soft texture, the inventors found that they have developed a polyolefin film that is insoluble, infusible, and has low swelling properties and has a crosslinked structure. The present inventors have discovered that these characteristics are expressed in a film obtained by mixing a specific amount of polymer particles of a specific particle size with a polyolefin resin and extrusion molding the mixture, and have completed the present invention.

In the case of B crosslinking, in order to maintain insolubility, infusibility, and low swelling, the irradiation dose must be I Mrad or more. If it is less than I Mrad, the above-mentioned characteristics of the present invention are weakened, and no superior advantage can be found.

Their gender was also inferior. In addition, particles that are too small are difficult to manufacture. On the other hand, if the thickness exceeds 50 μm, blocking resistance and slipperiness will be improved, but the feeling of sagging and rustling will not be improved, a rough feeling will appear, and it will be difficult to obtain a thin film with a thickness of about 40 μm or less, resulting in reduced productivity. is also significantly reduced.

あり、均一なフィルム化が困難である。That is, although films containing these water-absorbing polymer particles have improved slipperiness and soft feel to some extent, when stored for a long period of time, the feel and slipperiness change over time due to their hygroscopicity. Further, when forming a film, even if the raw material is sufficiently dried, minute pinholes tend to occur, making it difficult to form a uniform film.

ので好ましい。また、フィルムの均一性も良好である。In order to mix and disperse the crosslinked polymer particles in the polyolefin resin, a conventional kneading extruder that melt-extrudes the polyolefin resin can be used. For example, cross-linked polymer particles are mixed with some polyolefin resin in advance and melt-extruded using an extruder to produce master pellets containing many cross-linked polymer particles.This master pellet is then mixed with the remaining polyolefin resin and melted using an extruder. Forming an extruded film is preferred because the crosslinked polymer particles are more uniformly dispersed. Moreover, the uniformity of the film is also good.

By varying the proportions from time to time, it is easy to select the appropriate amount of particles in the film.
