Now, when the first agent and the second agent of the two-part hair dye are stored in the first package 12 and the second package 13 respectively, the first package 12 The dye and ammonia in the agent gradually penetrate into the sheet material 16 from the inside and try to leak out. However, since the dye and ammonia cannot penetrate into the aluminum film 17, they cannot penetrate to the surface of the first package 12, so that the amount of dye and ammonia in the first agent decreases during storage. It is not.

Further, in the second package 13, the internal pressure gradually increases as hydrogen peroxide in the second agent is gradually decomposed to generate oxygen. However, when a certain pressure is reached, oxygen is discharged from the concave portion 21 to the outside.
There is no possibility that the second package 13 expands during storage.

When using the two-part hair dye stored in the hair dye packaging bag 11, the hair dye packaging bag 11 is first folded in two at the perforation 14, as shown in FIG.

Therefore, the storage stability of the first part of the two-part hair dye can be improved.

The sheet material 1 forming the second package 13
A recess 21 is formed in 6, and oxygen can pass through the recess 21. For this reason,
When the internal pressure of the second package 13 increases due to oxygen generated by the decomposition of hydrogen peroxide in the second agent, oxygen can be discharged to the outside. Therefore, at the time of storage, the second package 1
There is no fear of the swelling of 3 and the storage stability of the second part of the two-part hair dye can be improved.

The thickness of the aluminum film 17 of the sheet material 16 is preferably set in the range of 5 to 20 μm. For this reason, it is possible to prevent the dye and ammonia in the first agent from penetrating into the surface of the first package 12 while maintaining the ease of squeezing the contents from the respective packages 12 and 13.
