Abstract

The invention provides a convenient square-bottom bag and a manufacturing method thereof. The convenient square-bottom bag comprises a bag body, a connecting band and a connecting plate, wherein the connecting band is arranged on one side of the top of the bag body, the connecting plate is arranged at one end of the connecting band, and a storage bag is arranged on one side of the connecting plate. The bag body comprises a first side bag face, a second side bag face and a bottom bag face, wherein the first side bag face, the second side bag face and the bottom bag face are connected in a sticking manner, separation bags are arranged on the upper portions of the inner sides of the first side bag face and the second side bag face, the two sides of each separation bag are bevel edges, and sticking blocks are arranged on the upper portions of the inner sides of the first side bag face and the second side bag face and used for adsorbing the inner sides of the separation bags. According to the convenient square-bottom bag, the storage bag on the bag body is used for storing the bag body, due to the fact that the bag body is made of a non-woven fabric and a reinforcing film and is soft intexture, the bag body can be stuffed into the storage bag when not used, and then the whole square-bottom bag is compressed into the size of the storage bag and is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of square bottom bags, in particular to a convenient square bottom bag and a manufacturing method thereof. Background technique [0002] The bottom of the square bottom bag is square. The square bottom bag generally has 5 sides, the front and the back (ie, the front wall and the back wall), two sides, and the bottom surface. The square bottom bag can stand, also known as a standing bag. The unique structure of the bottom bag determines that it is more convenient to pack three-dimensional goods or square products; [0003] When the existing square bottom bag is carried, it is generally folded into a thin surface by folding the edges on both sides, and then the area of ​​the bag body is still relatively large, so it is not easy to be stored in the pocket, and the existing square bottom bag generally adopts ordinary plastic film The material has poor toughness, is easy to break and damage, and pollutes the env...
