Abstract

PURPOSE:To provide a method to perform subdivision-pack packaging for a powdery detergent, etc., speedily using a water-soluble film. CONSTITUTION:To manufacture a subdivision-pack packaging body in which a powdery detergent 6 is filled, using a water-soluble film 7, a rotary type filling/packaging machine is used as a packaging machine, and the water-soluble film is heat-sealed first, while keeping the tension of the water-soluble film 7 at the time of heat-sealing at 7.0X10<-4>kgf/mm width or lower, to obtain a bag shaped water-soluble film with an opening. Then, a powder and/or granular object are filled in the bag shaped water-soluble film, and the opening of said water-soluble film is closed by heat-sealing to obtain a subdivision-pack packaging body.

する要望が高まっている。[Prior Art and its Problems] Conventional powdered detergents are often sold in boxes, and each time the laundry is done, the appropriate amount of detergent is poured into the washing machine with or without measuring using a spoon, measuring cup, etc. is used. However, with this method, it is difficult to use detergent in proportion to the amount of laundry, which often results in waste, and the detergent often spills and inadvertently stains the floor or washing machine. In recent years, as a result of the increase in the number of employed women and the spread of coin-operated laundry machines, there has been an increasing demand for detergent in the form of sachets, which not only simplifies the measuring operation but also eliminates the need to carry large detergent packages.

殆どなされていない。[0003] Studies have been conducted on detergent packages, and methods using water-soluble films as packaging materials have been proposed. However, most of these studies have been conducted in terms of film, and there has been almost no study in terms of packaging machines suitable for actual production.

装されている。[0004]Currently, there are two types of packaging machines used to manufacture sachet-type detergent: one type in which the product is filled and packaged while flowing vertically (hereinafter referred to as the vertical type), and the other type in which the product is filled and packaged while rotating horizontally. There are types (hereinafter referred to as rotary types) that can be filled and packaged at high speed (herein, high speed refers to a packaging capacity of 300 bags or more per minute). The packaging materials used for these are usually polycello (cellophane/polyethylene), polyester/polyethylene, aluminum foil/polyethylene, wood-free paper/polyethylene, O
A relatively strong water-insoluble composite film or sheet such as PP/polyethylene or filter paper is used and sealed by heat sealing. In addition to powder detergent and granular bleach, the main fillings include granulated sugar, powder/granules, silica gel, powdered juice, food additives, dashi stock, ramen soup, tea bags, sanitary rags, chocolate, Packed with peanuts, ramune sweets, etc.

といわれていた。[0005] The reason why water-soluble films are not used in the above-mentioned packaging machines is that the water-soluble film itself has "
Due to the lack of a strainer, conventional methods can cause the film to stretch or even break during filling and packaging, and water-soluble films were said to be unsuitable for rotary-type filling and packaging machines.

【０００６】上記２つタイプの包装機の中でバーティカ

装方法である。Among the above two types of packaging machines, the vertical type packaging machine is a packaging method that does not apply much tension in addition to its own weight when transporting the package, compared to the rotary type packaging machine.

。[0007] The present inventors have confirmed that packaging using a water-soluble film is possible in a vertical type packaging machine using stick (back seal) packaging. However, vertical type automatic filling and packaging machines are not suitable for high-speed filling using water-soluble films (up to
Therefore, there was a limit to the number of products that could be produced.

By maintaining the tension of the water-soluble film at 7.0 x 10-4 kgf/mm width or less during heat sealing, powder materials can be processed without the film stretching or breaking due to tension during transportation.
The present inventors have discovered that it is possible to manufacture divided packages filled with granules at high speed, and have completed the present invention.

The following can be used, and even films with a weight of 5 kg/mm2 or less can be packaged satisfactorily. The film is preferably a polyvinyl alcohol (hereinafter referred to as PVA) single-layer film that has excellent water solubility and is heat-sealable. The thickness of the film is not particularly limited, but is usually 10 to 1
00μ, and can be packaged satisfactorily even with a thickness of 50μ or less. If flexibility is required for the film, a plasticizer may be added. Further, during production, a surfactant may be added to improve releasability from the drum. In addition, fragrances and the like may be added depending on the case.

体を得ることができることが見出された。Normally, when manufacturing divided packages using a rotary type filling and packaging machine, it is recommended to apply tension to the polymer film at the unwinding roll section in order to suppress meandering during conveyance of the polymer film. However, surprisingly, in the present invention, in order to perform the above operation (a), from the unwinding roll section of the rotary type filling and packaging machine to the heat sealing section (A' in Figure 1) ~
Between A), the tension of the water-soluble film is 7.0×1
It has been found that by maintaining the width to 0-4 kgf/mm or less, water-soluble film sachets can be obtained extremely efficiently and without any trouble.

There is no particular limitation, and for example, it may be cast onto a support having an uneven surface, or a flat film may be formed by post-processing using an embossing calender.

R-10 A type (rotary type horizontal three-sided seal automatic filling and packaging machine) Fig. 1 shows a schematic diagram. In addition, the tension was determined by determining the loads W and θ applied to the roller 9 at points A and A' in FIG. 1 as shown in FIG. 2, and calculating the T value using the following formula, which was defined as the tension value. W=2T・COSθ/2 ・Detergent used: Attack (product name) manufactured by Kao Corporation
It was filled so that the bulk density was 0.7 g/cc and 12.5 g per bag. The evaluation results in the table are as follows: ○: There is almost no elongation of the film, and the detergent is packaged neatly. △: Elongation occurs on the film, and the shape is distorted even when the detergent is packaged. ×: The film elongates, Furthermore, cuts occur, which means that the detergent is not packaged properly.
