Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. In the description of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", etc. indicate the orientation or positional relationship based on that shown in fig. 2, and are only for convenience of describing the present invention without requiring that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and 2, the full-environment-friendly square-bottom valve-port packaging bag comprises a bag body 1, preferably, the bag body 1 is composed of a raw paper layer 11 and a film layer 12 which are sequentially bonded from outside to inside, and the film layer 12 can effectively improve the sealing performance of the bag body 1 and prevent materials contained in the bag body 1 from being affected with damp; further, as shown in fig. 3, the raw paper layer 11 is formed by bonding three layers of kraft paper 111, which greatly enhances the strength of the bag body 1, and avoids the situation that when the material contained in the bag body 1 has a sharp shape, the packaging bag is scratched, and the material is exposed or even flows out. Preferably, the cross-section of the bag body 1 is rectangular, so that the bag body is convenient to store, and the storage space is saved. An opening 2 is formed in one corner of the bag body 1, and materials enter the bag body 1 through the opening 2.
