Definitions
- the present invention relates to a method for supplying a gas absorbent, and more particularly, to a method for supplying a gas absorbent for absorbing a harmful gas for storing articles to a hermetically sealed packaging container containing articles such as food.
- such a gas absorbent generally has a force used in the form of an envelope (hereinafter simply referred to as an encapsulated gas absorbent) encapsulated by an envelope film.
- an encapsulated gas absorbent encapsulated by an envelope film.
- a breathable film such as a paper-perforated plastic film is used as the enveloped film. Therefore, any conventional encapsulated gas absorbent has the disadvantage that, if it is exposed to the atmosphere as it is, it absorbs the target gas contained in the air, and its gas absorption capacity is impaired. Have.
- a substantially air-impermeable envelope is formed as a whole having a structure in which an air-impermeable plastic film is laminated or overcoated on a surface of a gas-permeable heat-resistant film.
- the non-breathable plastic film forms an outer surface and encloses the gas absorbent.
- At least a part of the surface of the agent is pressed against the heated piercing member to form a vent only in the plastic film layer forming the surface of the encapsulated film, Then, the encapsulated gas absorbent capable of absorbing gas is supplied into a hermetically sealed container containing required articles, and the container is hermetically sealed.
- the gas absorbent used in the present invention may be used for protecting articles such as oxygen, moisture, odor, carbon dioxide, or harmful waste (for example, hydrogen sulfide, sub-gas).
- ⁇ M? 1 Is it a generic term for substances that adsorb or absorb gas components?
- these include various oxygen scavengers such as iron powder and hydrosulfite for deoxygenation, and silica gel and zeolite for dehumidification or drying.
- oxygen scavengers such as iron powder and hydrosulfite for deoxygenation, and silica gel and zeolite for dehumidification or drying.
- metal hydroxides such as sodium hydroxide, calcium hydroxide, magnesium hydroxide, calcium oxide, magnesium oxide, etc. And acid Stuff etc. there
- the gas absorbent a substance having a physical adsorption action or a chemical reaction action with respect to the component to be removed from the atmosphere is used.
- the gas absorbent is used in the form of powder or particles, and its particle size is not particularly limited, but is generally 0.5 mm or less, preferably 150 or less, and more preferably 5 or less. Used in the form of fine particles of 0 or less.
- FIG. 1 shows a cross-sectional explanatory view of the envelope according to the present invention
- FIG. 2 shows a new surface explanatory view of the envelope film.
- 1 indicates a gas absorbent
- 2 indicates an encapsulating film
- 3 indicates a non-breathable plastic film
- 4 indicates a breathable heat-resistant film.
- the non-breathable plastic film 3 used in the present invention only needs to be a heat-meltable or thermally decomposable material, and various plastic films are applied to such a material.
- plastic films such as polyethylene, polypropylene, and polybutadiene, polyesters such as polyethylene terephthalate, nylon 6, nylon 6,6, polyamide, polyvinyl chloride, etc.
- films include polybutene compounds, polystyrene, and polyatalylate.
- films such as the plastic film of the present invention, in addition to the above-mentioned polymers, films such as copolymers and blends thereof are also applied, and furthermore, laminating films thereof are also applied.
- the thickness of this film is usually 5 or more, preferably 20 to 100.
- the air-permeable and heat-resistant film used in the present invention may be any one having a high melting point or a high thermal decomposition point and a gas-permeable property as well as the above-mentioned plastic film.
- Examples of such paper include thin paper, paraffin paper, oil paper, asphalt paper, astringent paper, parchment paper, pseudo parchment paper, printing paper, and other types of paper. is there.
- these air-permeable heat-resistant films can be a laminate in which an air-permeable plastic film such as a perforated plastic film is laminated on the back surface to strengthen the film. The reinforcing breathable plastic film laminated on the back of this paper must be heat-resistant.
- the gas absorbent encapsulated by the encapsulating film has a gas-absorbing reaction even when it is left in the air because the encapsulating film is entirely impermeable. There is nothing that can happen.
- a perforating member heated at least on at least a part of the surface of the encapsulated film is pressed. Then, pores of a required size are formed only in the plastic film layer 3 forming the surface of the encapsulating film.
- the perforating member may be a rod or needle having good thermal conductivity, such as metal, wound around a nickel wire, or a rotary heating port having a built-in electric heating element.
- a hot plate having a large number of parts formed on the surface is used.
- the shape of the surface of the perforating member to be brought into contact with the plastic film 3 is arbitrary, and it can be brought into surface or point contact with the film surface, and a hole of a shape and size corresponding to that is made of a plastic. Drilled in Film 3.
- the temperature of the piercing member when the piercing member is brought into contact with the surface of the envelope is sufficient to melt or thermally decompose the plastic film 3, but incinerate the heat-resistant film 4. It is a temperature that will not be noticeable.
- the specific heating temperature is appropriately determined in consideration of the thermal properties of the plastic film 3 and the heat-resistant film 4 to be applied.
- the perforating member can be heated to about 200 to 400C. When this perforating member is pressed against one or both surfaces of the enveloped gas absorbent, only the portion of the plastic film layer 3 forming the surface of the enveloped film that comes in contact with the perforating member is heated.
- FIG. 3 shows a cross-sectional explanatory view of the encapsulating film in which the ventilation holes are thus formed.
- reference numeral 5 denotes a vent.
- sealed container used in the present invention is widely interpreted, and includes various types of sealed containers that have been generally used in the past, such as bags, cylinders, boxes, trays, and cans.
- the required gas vents are formed only in the surface plastic film layer of the encapsulating film in this way, and the encapsulating gas absorbent which is capable of absorbing gas can be used. As soon as possible, it is supplied to the container that contains the goods and is sealed in the container with the goods.
- the perforating member used in the present invention is preferably combined with an automatic supply device for automatically supplying the encapsulated gas absorbent. That is, the heating member is attached to a supply port of a supply device that periodically supplies the enveloped gas absorbent, and the heated perforating member is provided on one or both sides of the enveloped gas absorbent passing through the supply path. To obtain an encapsulated gas absorbent to which gas absorption reactivity has been imparted.
- the encapsulated gas absorbent is released into the air under normal conditions. ⁇ It does not react even if it is placed, and a vent is formed in the surface during supply, and it is supplied to the sealed container in the state where the reaction is started, so automatic supply is also easy 3 ⁇ 4 ⁇ ) No loss of gas absorption capacity
- the ventilation hole is a surface plastic film.
