DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film for use in an ostomy pouch for mounting various excretions coming out of a human body through the opening, which is mounted on an opening formed in the surface of a human body. .

[0002]

2. Description of the Related Art In order to treat filth discharged from a living body through an opening formed on the surface of a human body due to various diseases, a so-called stoma, a skin attached to the periphery of the stoma is used. It is common practice to attach a pouch on the opposite side of the skin from the skin side and collect the effluent from the stoma in the pouch. This ostomy pouch is formed by cutting a heat-sealable flexible film into a predetermined size and heat-sealing the two films. One side of the pouch has an opening so that it can be joined to a stoma. A junction is provided around the portion and the periphery thereof.

[0003] Since the ostomy pouch is for temporarily storing the discharged material, the discharged material and its odor do not leak to the outside, have sufficient strength not to be broken by external pressure, and are repeatedly used. No pinholes due to bending, no suppleness to the skin, no suppleness, no noise during wearing, good slipperiness so that discharged materials fall to the bottom of the pouch, and when using the pouch It is required that the film has a function of preventing sticking of the films so that the mouth can be easily opened (that is, the film has an excellent anti-blocking property). Therefore, the film used for this ostomy pouch has odor barrier properties, high tensile strength, high tear strength, high piercing strength,
High heat seal strength, flex resistance, flexibility, quietness, slipperiness, anti-blocking properties, and the like are required.

Heretofore, as a film used for an ostomy pouch, a film in which an odor preventing layer made of polyvinylidene chloride resin and a flexible resin layer are laminated by a co-extrusion method is known. For example, JP-A-7-148192 discloses a coextruded laminated film in which an ethylene-vinyl acetate copolymer layer is disposed on both sides of a deodorizing layer composed of a vinylidene chloride-vinyl chloride copolymer.

An ostomy pouch using this film is excellent in odor barrier properties, tensile strength, tear strength, piercing strength, heat sealing strength, flexibility, slipperiness, and blocking resistance, but has a low noise and bending resistance. There was a drawback that it was inferior.

Also, in Example 2 of JP-A-11-19108, a 30 μm thick film of an ethylene-1 hexene copolymer polymerized by using a metallocene catalyst was provided on both sides of a 15 μm thick polyvinylidene chloride film. A laminated film laminated with Tamapoli SE605M) is disclosed. The method of laminating the laminated film is unknown because there is no specific description and the physical properties of the film are not disclosed, but since there is no particular description, it is presumed to be a dry lamination method. Therefore, as a result of reproducing Example 2 of JP-A-11-19108, the obtained laminated film is excellent in odor barrier properties, tensile strength, tear strength, piercing strength, heat seal strength, slipperiness, and blocking resistance. However, there were drawbacks in that the flexibility and the noise were significantly inferior, and the bending resistance was slightly inferior.

If the combined thickness of both layers is more than 110 μm, the flexibility of the film may be insufficient and a feeling of discomfort may occur during mounting. In addition, the thickness of the flexible film may be different in each layer within the above range. For example, one side is 25 μm,
The other side can be 30 μm or the like. The thickness of the pressure-sensitive adhesive layer in the film of the present invention is 2 μm in each layer.
m or more, and the total thickness of both layers is preferably 80 μm or less. When the thickness of each layer is less than 2 μm, the noise is poor. When the thickness of both layers is more than 80 μm, the strength of the film is insufficient and the pouch may be deformed by the weight of the collected waste. The thickness of the pressure-sensitive adhesive layer may be different in each layer as long as it is within the above range. For example, 5μ on one side and 10μ on the other side

Example 2 of JP-A-11-19108
Was reproduced, and the results are shown in Comparative Examples 4 and 5 below. As described in the section of the prior art,
In Example 2 of JP-A No. 9108, a 15 μm thick polyvinylidene chloride film was coated on both sides with a 30 μm thick ethylene-1 hexene copolymer polymerized using a metallocene catalyst.
m (SE605M manufactured by Tamapoli Co., Ltd.) is laminated. The method of laminating the laminated film is unknown because there is no specific description and the physical properties of the film are not disclosed, but since there is no particular description, it is presumed to be a dry lamination method. According to the description of “Lamination Handbook” published by Processing Technology Research Group on page 122, “one-pack type adhesive is a prepolymer having isocyanate group, or polyether polyol, polyester used for dry lamination method. It is a two-component type consisting of a polyol or a base agent composed of urethane or epoxy modified product thereof and a curing agent having an isocyanate group dissolved in a solvent. " I understand. Therefore, a dry lamination method using the above-mentioned adhesive is disclosed in JP-A-11-19108.
Example 2 was reproduced. At this time, since there is no specific description other than the thickness of the polyvinylidene chloride film, the Saran UB manufactured by Asahi Kasei Kogyo Co., Ltd. and Kurehalon K.FLEX manufactured by Kureha Chemical Industry Co., Ltd. used.

Takerac A606 manufactured by Takeda Pharmaceutical Co., Ltd. as a urethane-based adhesive
/ A10 (two-component type whose main component is a polyester polyol as a main component) was laminated with a dry laminator to obtain a laminated film having a total thickness of 80 μm. At that time, the adhesive was dried in a drying oven at 70 ° C. for 10 seconds. Table 9 shows the results of evaluating the performance of the obtained laminated film.

Comparative Example 5 Kureha Chemical Industry Co., Ltd. as a polyvinylidene chloride film

Using Takeda Pharmaceutical Co., Ltd. Takerack A606 / A10 (two-pack type whose main component is a polyester polyol as a main component) as a urethane-based adhesive, a dry laminator is used to bond the whole to a thickness of 80 μm. A laminated film was obtained. At that time, the adhesive was dried in a drying oven at 70 ° C for 1 hour.
Dry for 0 seconds. Table 9 shows the results of evaluating the performance of the obtained laminated film.

From the performance evaluation results of the examples shown in Tables 1 to 8 and the comparative examples shown in Table 9, the film obtained by the conventional co-extrusion method has good odor prevention, flexibility and load bearing strength, but has a low noise level. Inferior in flexibility and bending resistance, and the film obtained by dry lamination has good odor resistance and load-bearing strength, but the flexibility and the quietness are very poor and the bending resistance is slightly inferior. It can be seen that the film has good deodorant properties, flexibility and load-bearing strength, and also has excellent characteristics in noise reduction and bending resistance.
Therefore, it is understood that the film of the present invention is more suitable as a film for an ostomy pouch than a film formed by a conventional coextrusion method or a film formed by dry lamination.
