[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] Example 1:

[0030] The present application embodiment discloses a food packaging bag, referring to Figure 1 , including a bag body 1, a accommodating cavity is opened in the bag body 1, an opening connected to the accommodating cavity is opened at one end of the bag body 1, and a sealing part 11 is provided at the opening of the bag body 1. When the food is packaged for the first time in the factory, it is packaged through the sealing part 11, thereby improving the sealing performance of the bag body 1 and thereby improving the shelf life of the food.

[0031] Reference Figure 1 The bag body 1 is provided with a sealing strip 14 on one side of the sealing portion 11 near the middle of the bag body 1. The bag body 1 is provided with an easy-tear notch 12 between the sealing strip 14 and the sealing portion 11. The bag body 1 is fixedly connected to an easy-tear strip 13 located at the easy-tear notch 12 to cover the easy-tear notch 12. When eating, the eater tears the easy-tear strip 13 to take out the food through the opening at the easy-tear notch 12 and the sealing strip 14, and the sealing strip 14 can be used to seal the opening for secondary storage of the food.

[0032] Reference Figure 1A one-way valve 2 is fixedly connected to the bag body 1, and the one-way valve 2 is connected to the accommodating chamber. The one-way valve 2 allows the gas to be discharged only from the accommodating chamber to the outside of the bag body 1. When the sealing strip 14 is sealed, if the eater accidentally squeezes the bag body 1, the gas in the accommodating chamber can be discharged through the one-way valve 2, thereby reducing the possibility of the bag bursting. The one-way valve 2 can also prevent the outside oxygen from entering the bag to reduce the possibility of oxidation of the food in the bag.

[0033] The implementation principle of Example 1 of the present application is: when the sealing strip 14 is sealed, if the eater accidentally squeezes the bag body 1, the gas in the accommodating cavity can be discharged through the one-way valve 2, thereby reducing the possibility of the bag bursting. The one-way valve 2 can also block the outside oxygen from entering the bag to reduce the possibility of oxidation of the food in the bag.

[0034] Example 2:

[0035] The difference between Example 2 and Example 1 is that, referring to Figure 2 and Figure 3 The bag body 1 is detachably connected to a winding rod 3, which is provided with a clamping piece for clamping the bag body 1. The winding rod 3 is provided and clamped to one end of the bag body 1 through the clamping piece. The bag body 1 is then rolled up by the winding rod 3 to discharge the air in the bag body 1 through the one-way valve 2, which is beneficial to the preservation of the food in the bag body 1 and reduces the possibility of the puffed food getting wet when stored in the bag body 1.

[0036] Reference Figure 2 and Figure 3 The clamping member is a clamping block 31 with a retaining groove 32 formed therein. Two clamping blocks 31 are provided, one on either side of the axis of the winding rod 3. The clamping blocks 31 are fixedly connected to the peripheral wall of the winding rod 3, with the retaining grooves 32 facing the same side. The clamping blocks 31 are located on either side of the winding rod 3. During the clamping process, the winding rod 3 passes through the tear-off notch 12, resulting in a staggered connection between the clamping blocks 31 and the bag body 1 along the axis of the winding rod 3, thereby improving clamping stability.

[0037] Reference Figure 2 and Figure 3 The clamping block 31 is located at the slot of the clamping groove 32 and a limit block 33 is provided. The cross section of the limit block 33 is semicircular. The outer peripheral wall of the limit block 33 abuts against the slot wall of the clamping groove 32 away from the limit block 33. The clamping block 31 is elastically arranged.

[0038] Reference Figure 2 and Figure 3 A penetration belt 15 is provided on the side of the bag body 1 away from the sealing part 11. There are two penetration belts 15 and they correspond to the two clamping blocks 31 respectively. Both ends of the penetration belt 15 are fixedly connected to the bag body 1. The middle part of the penetration belt 15 and the bag body 1 form a penetration hole for the clamping block 31 to pass through.

[0039] The implementation principle of Example 2 is as follows: a winding rod 3 is provided, which is clamped at one end of the bag body 1 by a clamping block 31, and then the bag body 1 is rolled up by the winding rod 3 to discharge the air in the bag body 1 through the one-way valve 2, which is beneficial to the preservation of the food in the bag body 1, and when the puffed food is stored in the bag body 1, the possibility of the puffed food getting damp can be reduced.
