Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery or granular chemical having a high hygroscopicity or corrosiveness, such as an inorganic chlorine compound and an anhydride thereof.
The present invention relates to a packaging material for transportation used for storage and transportation, which has excellent airtightness and chemical resistance and also has excellent high-temperature reactivity.

[0002]

2. Description of the Related Art In general, the transport of powdered and granular chemicals as industrial raw materials and products takes into account the physical and chemical properties of the powdered and granular chemicals, and is adapted to the conditions of use. In consideration of this, the container and the transportation means are selected.

[0003] However, some of such powdered chemicals exhibit strong hygroscopicity and corrosiveness. Generally, when these powdered chemicals are left open to the atmosphere, they can be found in the air. May absorb and dissolve water (deliquescence), or the main component may be decomposed by the absorption of water, generating corrosive gases such as hydrogen chloride and reducing purity. Or corrosive to transportation means, which may shorten its life.

Therefore, in transporting such a particulate chemical having a high hygroscopicity or a corrosive property, the particulate chemical is excellent in airtightness and corrosion resistance which can prevent invasion of air and molecular water. It is generally performed by filling a container.

[0005] For example, anhydrous chlorine compounds such as anhydrous aluminum chloride and anhydrous iron chloride are substances having such properties.
Considerable consideration has been given to transport, for example,
Measures have been taken such as using a plastic that can block the intrusion of molecular water and has excellent corrosion resistance to hydrogen chloride gas.

[0006] Specifically, as a container for transporting such a substance, for example, an iron container (iron container) made of thick steel plate for several tons is known. Although the specifications are different, there is a filling port and a discharge port, the whole is made sturdy, the lid provided for the filling port and the discharge port has excellent airtightness, and it is hard to break even in the event of an accident during transportation, There is an advantage in that there is little danger of discharging the contents, and there is a superiority in safety and the like and that it can be used repeatedly.

However, in recent years, in addition to product quality deterioration, container corrosion prevention, and transport safety, there is a demand for efficient and large-scale logistics. In addition, there is a demand for a container that does not require any trouble during the discharging operation. For this reason, in the conventional iron container, there is a problem in that the weight of the container itself in the transport weight is large, and the efficiency is poor due to the large volume for collecting empty containers. Also, in normal product transportation in Japan, there are many types of containers that are difficult to share according to the customer's acceptance situation, and when reusing iron containers, in order to maintain the quality of the next product to be filled. To
Complicated cleaning operations such as cleaning the inside, drying, and replacing air with high humidity are required.

[0008] In addition, the use of iron containers as containers for export is less preferred. This is because similar problems as described above become more pronounced.For example, it takes time to collect empty containers, so it is necessary to deal with increasing the number of containers. This is because it is expected that the management of the container will be complicated, which will increase the cost.

As another container for transporting such a substance, a resin-lined drum can is known. This drum can has a relatively light container weight and the outside is made of a metal strength protection material. In addition to being formed, the inside is resin-lined and has corrosion resistance, which solves the problems of iron containers.

[0010] Such a drum can is relatively lightweight, is excellent in corrosion resistance and moisture resistance, and is used as a common container in Japan and overseas and is generally distributed.
It is used in a so-called one-way manner, which has the advantage of logistics because it does not require time and effort for recovery, and is particularly suitably used for export.

However, since this drum can is one-way and disposable, it becomes expensive as a packaging cost,
The filling operation is about 200 kg per can, and the number of operations per unit weight is 4 to 5 times that of an iron container.
At the time of use, a dedicated container reversing device is required, so that the workability is also low and the cost of the product is increased.

[0012] Further, various multilayer resin films are known as packaging materials having high moisture-proof properties, and are used for packaging small quantities of several hundred grams, such as foods, portable heaters (disposable warmers) and the like. However, packaging with these multilayer resin films requires film thickness, strength, flexibility,
There are various practical problems such as the possibility of bag making and the difficulty of obtaining sheets of the size required for packaging materials. However, it is difficult to apply to large-sized packaging and transportation in units of tons, and it has not yet achieved all of the performance and functions equivalent to conventional transportation containers.

[0013] As a medium-sized packaging material having excellent moisture-proof properties for packaging powdered granules in units of tens of kilograms having a high hygroscopicity, a resin film such as polyethylene or polyvinyl chloride may be used. Paper bags of a multilayer film in which vinylidene chloride or aluminum foil and paper are laminated are known (JP-A-55-19522, JP-A-62-78).
059 and JP-A-63-178949). However, this type of paper bag using an aluminum foil cannot be used as a packaging material for such a substance because the aluminum foil is corroded because a resin film such as polyethylene or polyvinyl chloride transmits hydrogen chloride or the like. Further, this type of paper bag using polyvinylidene chloride has high moisture resistance, but the strength of the bag itself is low, so that it can be used for a 20 to 30 kg wrapping bag, but a larger weight, for example, 1 to 2 It cannot be used as a container for tons, and it is not suitable for substances that absorb moisture and generate gas, because the work of opening and charging the bag at the time of discharge is manual.

In particular, in the case of a granular chemical having a high hygroscopicity or corrosiveness, such as an inorganic chlorine compound and its anhydride,
At the same time, some exhibit strong high-temperature reactivity to various packaging materials, for example, anhydrous aluminum chloride, in particular,
When the temperature exceeds 40 ° C., it shows strong reactivity with resins such as low-density polyethylene, so that the filling is anhydrous aluminum chloride and the innermost layer of the multilayer resin film as the packaging material is low-density polyethylene However, there arises a problem that the quality cannot be maintained due to the reaction between anhydrous aluminum chloride and low-density polyethylene.

[0015]

Therefore, the present inventor has proposed:
It has excellent airtightness and chemical resistance, and also has excellent high-temperature reactivity.It is also convenient for handling such as filling and discharging, and is suitable for mass transportation. As a result of intensive studies to develop a packaging material for transportation, storage and transportation of highly corrosive granular chemicals, especially those with high reactivity at high temperatures, The material is formed into a double structure consisting of a bottle-type inner bag and a flexible container outer bag, and an inner-bag alteration preventive body having excellent high-temperature reactivity is provided inside the bottle-type inner bag, whereby The present invention has been found to achieve air-tightness, chemical resistance, and high-temperature reactivity, and to attain the object by imparting strength sufficient for handling such as transportation, storage, and transportation in a flexible container outer bag. Completed.

Accordingly, an object of the present invention is to provide a powdery or granular chemical which has excellent airtightness and chemical resistance, and also has excellent high-temperature reactivity, and is highly hygroscopic and corrosive, such as inorganic chlorine compounds and anhydrides thereof. In particular, it is an object of the present invention to provide a packaging material for transportation suitable for transportation, storage and transportation of a granular chemical having a high temperature reactivity.

Another object of the present invention is to provide a large packing amount per unit of packaging, easy collection and reuse of containers, and a small weight of the container relative to the weight of the product, which is suitable for mass transportation. It is to provide a packaging material for transportation.

That is, the present invention provides a bottle-type inner bag formed of a multilayer resin film having excellent moisture-proof, acid-resistant and gas-barrier properties, Combined with a flexible container outer bag having excellent strength, the inside of the bottle-type inner bag is separated from the filling material to be filled in the bottle-type inner bag to prevent deterioration of the bottle-type inner bag. Is provided with an inner bag alteration preventive body made of a high-temperature reactive resin.

In the present invention, the bottle-type inner bag has a shape that is gradually narrowed from the center of the bag to the lower outlet so that the entire amount of the contents is smoothly discharged. In order to prevent the deterioration of the contents and the diffusion of the generated hydrogen chloride gas to the outside, the multilayer resin film forming the bottle-type inner bag should have at least a moisture-proof, acid-resistant and gas-barrier resin. It is necessary to have a film layer (B). As the resin film layer (B), for example, polyvinylidene chloride, high-density polyethylene, polyethylene vinyl alcohol, polypropylene and the like can be mentioned. Particularly, polyvinylidene chloride, high density polyethylene, and polyethylene vinyl alcohol are preferred.

The bottle inner bag is provided inside the bottle inner bag for the purpose of preventing the bottle inner bag from being deteriorated due to the reaction of the bottle inner bag with the filling material filled in the bottle inner bag. An inner bag alteration preventing body that partitions between the inner bag and the filling is provided. It is necessary that the inner bag alteration preventive body is made of a high-temperature reactive resin that does not react with the filler even at high temperatures or hardly reacts. Further, as the resin for forming the inner bag alteration preventive body, a resin that can be sealed such as a heat seal is preferable from the viewpoint of complete moisture proofness.
When the filler is anhydrous aluminum chloride, polyvinyl chloride is preferably used.

The inner bag alteration preventive body is provided inside the bottle-type inner bag, so that the bottle-type inner bag does not come into direct contact with the filling material filled in the bottle-type inner bag.

The sealing resin film layer (C) is formed by laminating the sealing resin film layer (C), and the reinforcing resin film layer (D) is formed on the outer surface of the sealing resin film layer (C) for the purpose of reinforcing the entire multilayer resin film. May be bonded together. Further, a resin film layer (C) for sealing for the purpose of sealing such as heat sealing is bonded to both sides of the resin film layer (B) having excellent moisture proofness, acid resistance and gas barrier properties. Alternatively, a resin film layer for reinforcement (D) may be bonded to the outer surface of the resin film layer for sealing (C) located on the outside.

When used as a packaging material for a small amount that can be used up quickly with contents having relatively low hygroscopicity, the resin film layer (C) for sealing may not be present, but the moisture resistance is not completely improved. In order to completely prevent the generation of gas due to moisture absorption, a sealing resin film layer (C) is preferably present, and a reinforcing resin film layer (D) is further provided to prevent breakage. desirable.

Such a resin film layer for sealing (C)
Examples of the resin for forming a low-density polyethylene include low-density polyethylene, polyvinyl chloride, and polypropylene. Low-density polyethylene is particularly preferable from the viewpoint of multilayering with other films. Examples of the resin constituting the reinforcing resin film layer (D) include, for example, PE
T resin and the like.

It has a through hole at the top and bottom through which the filling port and the discharge port of the bottle-type inner bag penetrate on the bottom and the bottom, and has a hanging tool used for transportation and loading, such as polypropylene, rubber, etc. It is made of such a tough material as to have sufficient strength to withstand such operations as lifting the bottle-type inner bag during operations such as storing, transporting, handling, and discharging the product while storing the bottle-type inner bag. Preferably, the upper part is open, and the bottle-type inner bag can be easily inserted from the upper part, and the bottom part has an opening for discharging the bottle-type inner bag. From the bottle type The outlet of the bag bottom is exposed downward,
It is preferable to be able to discharge the inorganic chlorine compound and its granular chemicals such as anhydrides filled in the bottle-type inner bag from the outlet.

The packaging material for transportation of the present invention is, for example, a resin film layer (A) in which an inner bag alteration preventive is laminated on the innermost side of a multilayer resin film forming a bottle-type inner bag, and When the multilayer resin film constituting the inner bag has a resin film layer (C) for sealing, first, the outlet of the bottle-type inner bag is heat-sealed, and then the bottle-type inner bag is placed in the flexible container outer bag. Assemble and make the outlet of the bottle-shaped inner bag protrude outside from the bottom through-hole of the outer bag of the flexible container.In this state, use a tying device consisting of a thin string or velvet fastener provided at the opening edge of the bottom through-hole. The opening edge of the bottom through-hole is tied to the discharge port of the bottle-type inner bag, and the space between the bottle-type inner bag and the flexible container outer bag is fixed.

The inner bag deterioration preventing body is a partition bag for preventing deterioration of the inner bag, which is separately formed from the bottle-type inner bag made of the multilayer resin film, and this partition bag is disposed inside the bottle-type inner bag. When the multilayer resin film constituting the bottle-type inner bag has a sealing resin film layer (C), first, a partition bag for preventing deterioration of the inner bag and the multilayer resin film are used. The bottles are separately prepared, and then the bottles are put on the outside of the partition bags and overlapped so that the partition bags are disposed inside the bottle bags. Subsequently, the bottle-type inner bag in which the partition bag is disposed is loaded into the outer bag of the flexible container, and the outlets of the partition bag and the bottle-type inner bag are heat-sealed and closed, respectively. The part is made to protrude outside through the bottom through hole of the outer bag of the flexible container, and thereafter the operation can be performed in the same manner as in the above case.
