The user heats the content-enclosed pouch 1 with a microwave oven. The user takes out the content-enclosed pouch 1 from the microwave oven after the heating of the content-enclosed pouch 1 is completed. The user pinches the first grip 55 and the second grip 56 and opens the first opening 53 and the fastener 130. The user takes out the contents 600 and the like from the internal space 29.

The pouch 10 and the content-enclosed pouch 1 have the following effects.
(1) The pouch 10 has a first guide line 110 and a second guide line 120. The first guide line has a structure that separates the bag body 20. The first guide line 110 is formed on the first sheet 30 (first surface forming portion). The first guide line 110 has a first upward extending portion 111A (a step forming portion). The first upward extending portion 111A has a shape that extends in the upward direction HY1 from the first side seal portion 81 toward the inward direction HX1.

  The second guide line 120 has a structure that separates the bag body 20. The second guide line 120 is formed on the second sheet 40 (second surface forming portion). The second guide line 120 has a shape different from that of the first upward extending portion 111A.

  As an example, the pouch 10 is heated in a state where the contents 600 are enclosed. The temperature of the heated pouch 10 is relatively lower in the first side seal portion 81 than in the center in the width direction HX of the pouch 10. When the bag main body portion 20 is separated along the first guide line 110 and the second guide line 120, the pouch 10 and the first sheet 30 and the first sheet 30 are within a predetermined range in the inward direction HX1 from the first side seal portion 81. A step with respect to the two sheets 40, that is, a first grip portion 55 and a second grip portion 56 are formed. For this reason, in the pouch 10, the first grip portion 55 and the second grip portion 56 are formed at locations where the temperature is relatively low in the pouch 10. For this reason, the pouch 10 can suppress that a user feels uncomfortable opening work.

For this reason, the pouch 10 can increase the inclination angle of the formed first gripping portion 55 as compared with a pouch having a configuration in which the relay portion forming distance XC is longer than the first seal width XA. For this reason, the pouch 10 can form a step having a shape that is easier for the user to pinch.

  (4) The first guide wire 110 of the pouch 10 has a wave shape. The first guide line 110 is formed from the first side seal portion 81 to the second side seal portion 82. The second guide wire 120 of the pouch 10 has a wave shape that is different in phase from the first guide wire 110. For this reason, the pouch 10 has a step, that is, a grip portion, in the vicinity of the second side seal portion 82 when the bag body portion 20 is separated along the first guide line 110 and the second guide line 120. . For this reason, the pouch 10 can be opened from both the first side seal portion 81 side and the second side seal portion 82 side.

  (5) The first guide wire 110 of the pouch 10 has a wave shape. The second guide wire 120 of the pouch 10 has a wave shape that is different in phase from the first guide wire 110. For this reason, the user easily performs either the work of separating the bag body 20 from the front of the pouch 10 toward the back or the work of separating the bag body 20 from the back of the pouch 10 toward the front. be able to.

  (6) The outer surface 31A of the outermost layer 31 and the inner surface 43A of the innermost layer 43 have a color difference of ΔE1.2 or more, that is, a size that can be visually discriminated. The outer surface 41A of the outermost layer 41 and the inner surface 33A of the innermost layer 33 have a color difference of ΔE1.2 or more, that is, a size that can be visually discriminated. Therefore, in the pouch 10, when the bag main body portion 20 is separated along the guide line, the formed first grip portion 55 and the second grip portion 56 are easily recognized from either the front side or the back side. .

  (7) One end 110 </ b> A of the first guide line 110 coincides with one end 120 </ b> A of the second guide line 120 in the first notch 91. The other end 110 </ b> B of the first guide line 110 coincides with the other end 120 </ b> B of the second guide line 120 at the second notch 92. Therefore, when the pouch 10 separates the bag main body 20 along the first guide line 110 and the second guide line 120, the pouch 10 can make the first side edge 25 and the second side edge 26 beautiful. it can.
