[Prior Art] A label for in-mold molding that is required for the development of water resistance and is required for pharmaceutical use and durability. For example, a one-sided surface of a white film (synthetic paper) composed of a transparent film composed of an extended or non-stretched polyanthracene resin or a polyolefin resin in which an inorganic fine powder or an organic filler is extended or not stretched is In the process of producing a film, a heat-sealable resin is obtained by co-extruding various heat-sealable resin layers (Japanese Unexamined Patent Publication No. Hei No. Hei. No. Hei. A person who has been applied to the surface (Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. 2-122914) has been developed and partially commercialized. The conventional in-mold forming label is formed by in-mold forming so that the air enclosed between the container and the container escapes, is carved in the heat-sealed core layer during the manufacturing process, or is processed in advance by the engraving. It is necessary to provide a trapezoidal pattern when the film is bonded or phased. Moreover, when the pattern of such an empty space is not formed on the surface, the label itself is opened by opening the pores and the gas escapes ((4) Ping 2·Na峨 reading) 6 is proposed. 90848.doc I335343 Even in either case, the manufacturing steps become complicated, and it is impossible to avoid a decrease in productivity, an increase in the number of defective products, and an increase in manufacturing cost.

When a non-absorbent film is used, the coating of the hot resin or the heat-sealing resin is applied in a high-viscosity state by a gravure coater, and the trapezoidal pattern of the engraved parent compartment is attached to the surface of the substrate. Adopted. However, even in the case of 2, coating with a high degree is necessary, so that the problem of the lowering of the productivity, the use of the above-mentioned cost, or the use of an organic solvent to cause a fire or environmental pollution still exists. The present invention is directed to solving the problems of the prior art. In other words, in the present invention, when the heat-sealable resin coating layer is provided on the surface of the substrate film, it is not necessary to provide a specific pattern on the surface of the coating layer or to provide a through-hole. It is also possible to provide an expandable-selectable material constituting the heat-sealable resin layer, and to alleviate the limitations of the coating and processing equipment, and to extend the resin to a resin-extended film having a property of inferior productivity and in-mold labeling.

The average particle diameter of the dispersion of the heat-sealable resin is preferably larger than the average opening diameter of the surface of the substrate film. Further, after the heat-sealing resin is applied and dried, it is present in the form of particles on the surface of the base film. Therefore, it is necessary to dry at a temperature lower than the phase transition temperature of the heat-sealing resin (the temperature at which the solid phase state is transferred to the liquid phase state, also referred to as the film forming temperature). The phase transfer temperature of the heat-sealable resin is preferably 50 to 140 in terms of in-mold forming. (:, more preferably 55 to 13 (the range of rc.

The medium flow drying is carried out in a drying tower with hot air (8 〇 15 15 〇. 〇 in a fluidized state of the media particle group (flow layer): for the liquid-like substance, the liquid substance supplied is in a lively fluidization The method of "the surface of the particle is attached to the surface of the particle and dispersed in the flow drying, and the drying of the hot air is used to dry various substances. Such a medium flow can be used to flow the medium made by Nara Machinery Co., Ltd. The drying device "media siurry dryer" or the like can be easily carried out. If the medium is flow-dried, the drying and the agglutination of the particles (the removal of the primary particles can be carried out simultaneously), so that it is preferable to obtain a coarse amount by the same method. Very little carbonic acid ^ However, after the medium is dry and fluidized, the method of pulverizing and grading the particles is also carried out. When the medium is not dried by the flow of the medium and dried by the usual hot air to dry the wet pulverized product, the obtained block should be further The pulverization and classification of the lamp particles are carried out in a desired manner.
