Problems solved by technology

However, in this case, since a high-viscosity coating agent must be used, there are problems such as low productivity, high manufacturing cost, and the use of organic solvents is likely to cause fire and environmental pollution.
[0006] In addition, in the existing labels for in-mold molding, even though it is intended to print on the adhesive surface on the container, uniform, sharp and stable printing cannot be performed.
In addition, since these needs were not recognized, no significant research has been carried out on the printing of the adhesive surface of the in-mold label.

Embodiment

[0115] Hereinafter, the present invention will be more specifically described by taking preparation examples, production examples, working examples, comparative examples, and test examples as examples. Materials, usage amounts, proportions, processing contents, processing procedures and the like shown in the following examples can be appropriately changed without departing from the scope of the present invention. Therefore, the scope of the present invention is not limited to the explanation of the specific examples described below.

[0116] (Preparation example 1) Preparation of surface treatment agent (D)

[0117] In the reactor equipped with recirculation cooler, thermometer, dropping funnel, stirrer and gas inlet pipe, put into 500 parts by weight of diallylamine hydrochloride (concentration is the aqueous solution of 60% by weight), 13 parts by weight Parts of acrylamide (aqueous solution with a concentration of 40% by weight) and 40 parts by weight of water, and the tem...

manufacture example

[0122] The base film (manufacture examples 1-8) and the base film (manufacture examples 9-15) used in the comparative example which satisfy|fill the conditions of this invention were produced in the following procedure.

[0123] The materials used are detailed in Table 1. "MFR" in the table means melt flow rate. Table 2 describes the types and amounts (% by weight) of materials used in the production of various substrate films, stretching conditions, thicknesses of each layer, and opacity. The material numbers listed in Table 2 correspond to the material numbers listed in Table 1. In addition, the addition amount of the dispersing agent in Table 2 is represented by weight part with respect to 100 weight part of total addition amounts of materials 1-3.

[0124] In Production Examples 1 to 6, 9, and 10, the compound [A] described in Table 2 was melt-kneaded in an extruder set at 250°C, extruded, and then cooled to 70°C in a cooling device. A single layer unstretched sheet is ...

Embodiment 1～8、 comparative example 1～7

[0139] The dispersion composed of the heat-sealable resin described in Table 3, the anti-blocking agent described in Table 3, and water were mixed so as to obtain a predetermined solid content concentration to prepare a water-based coating agent described in Table 4. The water-based coating agent was coated on the front side of the base film of Production Examples 1 to 15 with a slot die coater at a linear speed of 20 m / min, and dried in a furnace with a set length of 10 m at the drying temperature recorded in Table 4. A heat-sealable resin coating was formed to obtain a film for in-mold forming labels. Table 4 shows the coating amount of the obtained film after drying.

[0140] Ink-jet printing and gravure printing were carried out on the surface of the heat-sealable resin coating of the obtained film under the following conditions. After making the inner surface decoration pattern, it was punched out with a length of 70 mm and a width of 60 mm to produce a label for in-mold ...

Abstract

The oriented resin film is obtained by forming an aqueous heat-sealable resin coat layer (E) on a base material film having a liquid absorption coefficient of >=5ml / m<SP>2< / SP>(ms)<SP>1 / 2< / SP>.

Description

technical field [0001] The present invention relates to an in-mold molding (Inmould molding) that adheres to a thermoplastic resin container produced by differential pressure molding, hollow molding, injection molding, foam molding, stretch blow molding, or compression molding while the container is being molded. Label. In particular, it relates to an in-mold label printed on an adhesive surface and an in-mold container with a label attached to a transparent container. Background technique [0002] In recent years, in-mold labels that must have water resistance, chemical resistance, and durability have been developed. For example, some types of products that have been developed include transparent films made of stretched or unstretched polyolefin resins and stretched or unstretched polyolefin resins mixed with inorganic fine powder and organic fillers. On one side of white film (synthetic paper), etc., types of co-extrusion of various heat-sealable resins during the film m...
