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.

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.

(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.
