Zipper structure and related zipper bag

A zipper bag comprising:

• a bag body comprising two plate-shaped components connected to each other by plastic welding, the bag body being formed with a chamber and an opening communicated with the chamber;
• and
• a zipper structure disposed on the bag body and located at a position corresponding to the opening, the zippering structure being located between the two plate-shaped components and comprising:
• a first zipper component comprising a first zipper portion and connected to an inner side of one of the two plate-shaped components by plastic welding;
• a second zipper component comprising a second zipper portion and connected to an inner side of another one of the two plate-shaped components by plastic welding, the first zipper portion and the second zipper portion having matched shapes for being detachably engaged with or separated from each other, an end part of the first zipper portion of the first zipper component adjacent to an end of the first zipper component and an end part of the second zipper portion of the second zipper component adjacent to an end of the second zipper component being engaged with each other;
• and
• an sealing end assembly connected to the end of the first zipper component and the end of the second zipper component by injection molding and located between the two plate-shaped components, the sealing end assembly covering a surface of the end of the first zipper component and a surface of the end of the second zipper component, a gap between the end part of the first zipper portion of the first zipper component adjacent to the end of the first zipper component and the end part of the second zipper portion of the second zipper component adjacent to the end of the second zipper component being filled with the sealing end assembly;
• wherein when the sealing end assembly is connected to the end of the first zipper component and the end of the second zipper component by injection molding, two surfaces of the sealing end assembly are respectively connected to the inner sides of the two plate-shaped components by plastic welding, and after the sealing end assembly is connected to the end of the first zipper component and the end of the second zipper component by injection molding, the two plate-shaped components are respectively connected to the first zipper component and the second zipper component and are connected to each other and the sealing end assembly by plastic welding.
