Referring to fig. 1 to 2, the present application provides a packaging bag with a heat-sealed and torn-open zipper, comprising a bag body 100 and a tearing line 200, wherein the bag body 100 comprises a first bag layer 110, a second bag layer 120, a male chain 130 and a female chain 140, and the periphery of the first bag layer 110 and the periphery of the second bag layer 120 are heat-sealed together to form a sealed fresh-keeping space. The male chain 130 is disposed on the inner side of the first bag layer 110 (i.e. the side of the first bag layer 110 facing the second bag layer 120) and extends along the width direction of the bag body 100, the female chain 140 is disposed on the inner side of the second bag layer 120 (i.e. the side of the second bag layer 120 facing the first bag layer 110) and is matched with the male chain 130, and the easy-tearing line 200 is U-shaped and the easy-tearing line 200 is disposed at the mouth of the bag body 100 for assisting tearing the heat sealed mouth.

When the instant food is eaten for the first time, a consumer can tear the bag opening of the bag body 100 along the easy-tearing line 200, and under the guidance of the easy-tearing line 200, the consumer can conveniently tear the packaging bag, and the tearing opening is regular and the shape and the size are controllable. The convex chain 130 and the concave chain 140 in the bag body 100 are matched to seal the packaging bag for the second time, which is beneficial to preserving food which is not eaten.

In the technical scheme of the application, the packaging bag with the heat-seal tearing opening with the built-in zipper comprises a bag body 100 and an easy-tearing line 200, and a consumer can conveniently tear the packaging bag under the guidance of the easy-tearing line 200, and the tearing opening is regular and the shape and the size are controllable. The bag body 100 is internally provided with the convex chain 130 and the concave chain 140, and the convex chain 130 and the concave chain 140 are matched with each other to carry out secondary sealing on the packaging bag, thereby being beneficial to preserving food which is not eaten. The food is packaged by using the packaging bag with the built-in zipper and the heat-sealing tearing port, so that the secondary storage life of the food can be effectively prolonged, and the consumption experience can be improved.

In a preferred embodiment of the present utility model, the slider 300 is mounted to the outer sides of the male chain 130 and the female chain 140, and is used for pulling and closing the male chain 130 and the female chain 140. By pulling the slider 300, the parts of the male chain 130 and the female chain 140 can be sequentially engaged, thereby achieving the effect of secondary closure. The sealing effect is better by compacting the male chain 130 and the female chain 140 by the slider 300. Since the opening of the pouch body 100 is formed as a U-shaped notch after the tear line 200 is torn, the pull head 300 can be effectively prevented from being released.
