押し出しラミネート法があるが、この考案はその何れを
も用いることができる。The polyethylene film laminating means is a conventionally known laminating method. That is, as a conventional laminating method, a dry laminating method using a glue layer,
There is an extrusion laminating method, but this invention can use any of them.
前記のようにして形成したラミネートフィルムは、強靱
性、良伝熱性、密封性にすぐれている。The laminate film formed as described above is excellent in toughness, good heat transfer and sealing property.
(作用) この考案は、ナイロンフィルム、ポリエチレンフィル

ィルムAを使用して、第1図に示すようにa、b、cの
三方をシールして袋Bを成形した。The laminated film A in the embodiment of the present invention comprises a nylon film 1 having a thickness of 25μ, a glue layer 2, a split cloth 3, a polyethylene film 4 having a thickness of 20μ, an aluminum layer 5 having a thickness of 9μ, a glue layer 6 and a thickness from the outside. The polyethylene film 7 having a thickness of 30 μ is laminated. Using the laminate film A, a bag B was formed by sealing three sides a, b and c as shown in FIG.
前記実施例の袋Bに、無菌的に濃縮乳酸菌液350mlを充
填し、C部をシールし、窒素を用いて−80℃に凍結す

しなかった。また所定の凍結状態に達するのに、缶では
10分間かかったが、この考案の袋では1分間かかった。The bag B of the above example is aseptically filled with 350 ml of the concentrated lactic acid bacterium solution, the part C is sealed, and it is frozen at -80 ° C using nitrogen. It was stored in a freezer at −80 ° C. for 30 days, but no abnormality was found in the bag or lactic acid bacteria. The bag was bent, but the bag was not damaged. In addition, in the can to reach the predetermined frozen state
It took 10 minutes, but the bag of this invention took 1 minute.
(対照例) ラミネートフィルムとして、外側より厚さ25μのナイロ

窒素を用いて−80℃に凍結後、袋を屈曲した所、一部に
破損がみられた。従って割布の有無が袋の強靱性に影響
することが判明した。(Comparative example) As a laminate film, a laminated film in which a 25 μm thick nylon film, a glue layer, a 20 μm thick polyethylene film, a 9 μm thick aluminum layer, a glue layer and a 30 μm thick polyethylene film are laminated from the outside. Make a bag, fill with 350 ml of concentrated lactic acid bacteria solution, seal,
After freezing to -80 ° C using nitrogen, when the bag was bent, some damage was seen. Therefore, it was revealed that the presence or absence of the split cloth affects the toughness of the bag.
(考案の効果) この考案はナイロンフィルム、割布、ポリエチレンフィ
ルム及びアルミニウム層のラミネートフィルムを用いて
袋を形成したので、低廉、強靱で取扱い容易な超低温用
保存袋として好適である。(Effect of the Invention) Since this invention forms a bag using a laminated film of nylon film, split cloth, polyethylene film and aluminum layer, it is suitable as a storage bag for ultra-low temperature which is inexpensive, tough and easy to handle.
また従来使用していた缶に較べて熱効率がよく、凍結時
間を著しく短縮できると共に、シール作業が簡単になる
などの諸効果がある。次に割布を挟着したので、凍結後
袋を屈曲しても、破損その他の損傷を受けるおそれはな
い。In addition, it has better thermal efficiency than conventional cans, can significantly shorten freezing time, and has various effects such as easy sealing work. Next, since the split cloth is sandwiched, even if the bag is bent after freezing, there is no risk of damage or other damage.
この考案の保存袋は、乳酸菌以外の物を充填する超低温
保存袋としても使用することができる。The storage bag of the present invention can also be used as an ultra-low temperature storage bag filled with a substance other than lactic acid bacteria.
