【実施例】【Example】

以下、本考案の一実施例について図面に従って説明する。 図1において、1は本考案に係る食品用包装シートで、極細繊維不織布層3と 該極細繊維不織布層3の両面にそれぞれ積層された長繊維不織布層5,5aとから3 層に構成されている。 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a food packaging sheet according to the present invention, which is made up of three layers of an ultrafine fiber nonwoven fabric layer 3 and long fiber nonwoven fabric layers 5 and 5a respectively laminated on both sides of the ultrafine fiber nonwoven fabric layer 3. There is.

【0009】 極細繊維不織布層3は、例えばメルトブロー製法により形成され、透湿性且つ 防水性を有しており、ポリオレフィン系樹脂、ポリエステル樹脂等からなるもの が使用できる。 両長繊維不織布層5,5aは、通気性且つ吸油性を有しており、ポリオレフィン系 、ポリエステル等の樹脂からなり、これら極細繊維不織布3及び両長繊維不織布 層5,5aは、点状あるいは線状等に熱エンボスあるいは超音波接着等の適宜手段に より一体に重合接着されている。 尚、極細繊維不織布層3及び両長繊維不織布層5,5aは、熱融着性に優れたポリ プロピレン等のポリオレフィン系樹脂からなるものが好ましい。The ultrafine fiber non-woven fabric layer 3 is formed by, for example, a melt blow manufacturing method, has moisture permeability and waterproofness, and can be made of polyolefin resin, polyester resin, or the like. Both long-fiber non-woven fabric layers 5 and 5a are breathable and oil-absorbent, and are made of a resin such as polyolefin or polyester. It is integrally polymer-bonded in a linear shape by an appropriate means such as heat embossing or ultrasonic bonding. The ultrafine fiber nonwoven fabric layer 3 and the both long fiber nonwoven fabric layers 5 and 5a are preferably made of a polyolefin resin such as polypropylene having excellent heat-sealing property.

【0010】 これら長繊維不織布層5、極細繊維不織布層3及び長繊維不織布層5aの重量構 成比は、図1に示す下側から1:1.2 :1.4 に設定するのが好ましく、また、通 気量29cc/cm2 /sec(JIS−L−1096A法による)、耐水度32(cmAq JIS−L−1092A法による)程度に設定されているのが好ましい。The weight composition ratio of the long fiber non-woven fabric layer 5, the ultrafine fiber non-woven fabric layer 3 and the long fiber non-woven fabric layer 5a is preferably set to 1: 1.2: 1.4 from the bottom shown in FIG. It is preferable that the air volume is set to about 29 cc / cm 2 / sec (according to JIS-L-1096A method) and the water resistance is 32 (according to cmAq JIS-L-1092A method).

【0011】 次に、上記構成からなる食品用包装シートの使用例について説明する。 図2(イ)において、一対の食品用包装シート1が矩形状に形成され、両食品 用包装シート1は、それぞれ重量比の小さな長繊維不織布層5が内側となるよう に、直交する2辺の縁部1a,1bがヒートシールされ、他の2辺の縁部1c,1dはシ ールされておらず、ここに食品9を出し入れ自在な開口10を有する包装体11が形 成される。この包装体11においては、主に内側の長繊維不織布層5が吸油用とし て、外側の長繊維不織布層5aは断熱用として機能する。Next, an example of use of the food packaging sheet having the above structure will be described. In FIG. 2 (a), a pair of food packaging sheets 1 are formed in a rectangular shape, and both food packaging sheets 1 have two orthogonal sides so that the long fiber nonwoven fabric layer 5 having a small weight ratio is on the inside. The edges 1a and 1b of the container are heat-sealed, and the other two edges 1c and 1d are not sealed, and the package 11 having the opening 10 through which the food 9 can be put in and taken out is formed here. . In this package 11, the inner long fiber non-woven fabric layer 5 mainly functions as an oil absorber, and the outer long fiber non-woven fabric layer 5a mainly functions as a heat insulator.

【0012】 そして、食品9を電子レンジで調理する際には、先ず、開口10から食品を包装 体11に入れて食品9を被覆し、この包装体11の開口部分を適宜折り込んで開口10 を閉塞し、電子レンジで食品を加熱調理する。電子レンジから発生するマイクロ 波により、食品9は加熱される。加熱時に、食品9より水蒸気が発生するが、両 長繊維不織布層5,5 が通気性を有すると共に、極細繊維不織布3は透湿性且つ防 水性を有することから、過剰な水蒸気は包装体11を通過して外部に放出され、包 装体11内で結露してべとつくことはない。When cooking the food 9 in a microwave oven, first, the food is put into the package 11 through the opening 10 to cover the food 9, and the opening of the package 11 is appropriately folded to open the opening 10. Block and cook food in microwave. The food 9 is heated by the microwave generated from the microwave oven. When heated, water vapor is generated from the food 9, but since both the long fiber non-woven fabric layers 5 and 5 have air permeability and the extra fine fibrous non-woven fabric 3 has moisture permeability and water resistance, excess water vapor will cause the package 11 to be overwhelmed. It passes through and is released to the outside, and does not condense and become sticky inside the package 11.

【0013】 また、この調理時に、食品9内部から油成分が現出してくる場合、現出した油 成分は内側の長繊維不織布層5に吸収されるので、食品9は油漬け状態になるこ とはなく、ふっくらとした状態に調理される。しかも、外側の長繊維不織布層5a は断熱効果を有し、食品9の保温が可能となる。また、長繊維の不織布であるた め、繊維の毛羽立ちが少なく、食品に付着しない。In addition, when the oil component appears from the inside of the food 9 during this cooking, the exposed oil component is absorbed by the long fiber non-woven fabric layer 5 on the inner side, so that the food 9 is put in an oiled state. Instead, it is cooked in a plump condition. Moreover, the outer long fiber non-woven fabric layer 5a has a heat insulating effect, and the food 9 can be kept warm. In addition, since it is a long-fiber non-woven fabric, the fibers do not fuzz and do not adhere to food.

【0014】 更に、前記食品用包装シート1の長繊維不織布層5,5aがポリオレフィン系樹脂 材料から構成されている場合には、熱融着性が良好となり、ヒートシールによる 製袋作業を容易に行うことができる。 尚、上記実施例では、一対の食品用包装シート1をヒートシールする構成を例 示したが、一枚の食品用包装シート1を2つ折りにし、この折り縁部に直交する 一辺をヒートシールしても良い。Further, when the long fiber non-woven fabric layers 5 and 5a of the food packaging sheet 1 are made of a polyolefin resin material, the heat-sealing property is good, and the bag-making work by heat sealing is facilitated. It can be carried out. In addition, in the above-mentioned embodiment, the configuration in which the pair of food packaging sheets 1 are heat-sealed is shown as an example. However, one food packaging sheet 1 is folded in two, and one side orthogonal to the folded edge is heat-sealed. May be.

【0015】 更に、本考案の食品用包装シート1の使用例は上記実施例に限定されるもので はなく、図2(ロ)に示す如く、上面が開口する容器15に食品9が収容され、容 器15の開口を閉塞すべく、食品用包装シート1が容器15の上縁部に固着されたも のであっても良い。また、図3に示す如く、一枚の食品用包装シート1で食品9 を直接包むことも可能である。この場合、食品用包装シート1は実質単層の不織 布と同等であるため扱い易く、例えば各家庭において、ロール状に巻回された食 品用包装シート1を適宜長さに切断して使用するのに便利である。Further, the use example of the food packaging sheet 1 of the present invention is not limited to the above-mentioned embodiment, and as shown in FIG. The food packaging sheet 1 may be fixed to the upper edge of the container 15 so as to close the opening of the container 15. Further, as shown in FIG. 3, it is possible to wrap the food 9 directly with one piece of the food packaging sheet 1. In this case, the food packaging sheet 1 is easy to handle because it is substantially the same as a non-woven fabric. For example, in each household, the food packaging sheet 1 wound into a roll is cut to an appropriate length. Convenient to use.

【0016】 尚、上記実施例では、電子レンジで食品9を調理する場合について例示したが 、食品用包装シート1は、調理された直後の温かい食品9を包んでも上記と同様 な効果が得られることは無論である。In addition, although the case where the food 9 is cooked in the microwave oven is illustrated in the above embodiment, the same effect as above can be obtained even if the food packaging sheet 1 wraps the warm food 9 immediately after being cooked. That is of course.

【0017】 また、食品用包装シート1を袋状に形成して蒸しあげ食品9を水密状に包装し ても良く、この場合には、包装体11により包装された食品9を熱水等に投入する と、極細繊維不織布層3は、熱水が包装体に浸入するのを阻止すると共に、水蒸 気が包装体内に入るのを許容するため、蒸し調理が可能となる。Further, the food packaging sheet 1 may be formed into a bag shape and steamed to package the food 9 in a watertight manner. In this case, the food 9 packaged by the package 11 is hot water or the like. When charged, the ultrafine fiber nonwoven fabric layer 3 prevents hot water from entering the package and allows water vapor to enter the package, so that steam cooking is possible.

【0018】 更に、食品用包装シート1は必ず3層の構成にする必要はなく、長繊維不織布 層5と極細繊維不織布3との2層から構成したものであっても良く、この食品用 包装シート1においては、長繊維不織布層5は吸油と断熱の機能を有する。更に 、食品用包装シート1は2層あるいは3層以外に、長繊維不織布層と極細繊維不 織布とを交互に複数積層したものであっても良い。Furthermore, the food packaging sheet 1 does not necessarily have to have a three-layered structure, and may be composed of two layers of the long fiber nonwoven fabric layer 5 and the ultrafine fiber nonwoven fabric 3. In the sheet 1, the long fiber non-woven fabric layer 5 has the functions of oil absorption and heat insulation. Further, the packaging sheet for food 1 may have a structure in which a long fiber non-woven fabric layer and an ultrafine fiber non-woven fabric are alternately laminated in plurality, in addition to the two or three layers.

【考案の効果】[Effect of device]

以上のように本考案の食品用包装シートは、通気性且つ吸油性を有する長繊維 不織布層と透湿性且つ防水性を有する極細繊維不織布とが積層されているので、 調理された食品からた発生する過剰な水蒸気を外部に放出でき、水蒸気が食品用 包装シート内で結露するおそれはなく、食品のべとつくきを防止できる。 As described above, since the food packaging sheet of the present invention is laminated with the breathable and oil-absorbent long-fiber nonwoven fabric layer and the moisture-permeable and waterproof ultra-fine fiber nonwoven fabric, it is generated from cooked food. The excess water vapor that is generated can be released to the outside, and there is no risk that water vapor will condense in the food packaging sheet, preventing the food from sticking.

【0020】 また、食品から油成分が現出しても、食品用包装シートは吸油性を有する長繊 維不織布層を有しているので、油成分を効果的に吸収可能となり、食品が油漬け の状態とならず、従って、上記水蒸気の結露を防止できるのと相まって、食品の 風味の低下を防止でき、商品価値が低下するおそれはない。Further, even if the oil component appears from the food, since the packaging sheet for food has the long fiber non-woven fabric layer having the oil absorption property, the oil component can be effectively absorbed and the food is soaked in oil. Therefore, it is possible to prevent the above-mentioned dew condensation of water vapor and prevent the flavor of food from deteriorating.

【0021】 しかも、長繊維不織布層をポリオレフィン系樹脂材料から構成した場合、熱融 着性が良好となり容易に製袋できる利点があり、電子レンジでの調理は無論、蒸 し調理にも採用できることから、その利用価値は著大である。Moreover, when the long-fiber non-woven fabric layer is made of a polyolefin-based resin material, it has an advantage of good heat-sealing property and easy bag-making. Needless to say, cooking in a microwave oven can be used for steam cooking. Therefore, its utility value is enormous.
