Description

Technical Field

[0001] The utility model relates to the technical field of composite film packaging bags, in particular to a composite film packaging bag convenient for sub-packaging. Background Technique

[0002] The composite film packaging bag is formed by combining two or more materials through one or more dry composite processes to form a packaging with specific functions; this kind of packaging can generally be divided into a base layer, a functional layer and a heat-sealing layer; the base layer mainly plays roles such as aesthetics, printing, moisture resistance, etc., while the functional layer mainly plays roles such as barrier, light shielding, etc.; the heat-sealing layer is in direct contact with the packaged article and has functions such as adaptability, moisture resistance, good heat-sealing property, transparency, and openability. Such a structure enables the composite film packaging bag to effectively protect the articles inside the package.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0023] This embodiment is a composite film packaging bag convenient for sub-packaging.

[0024] As Figures 1-4 shown, it includes an upper bag body 1 and a lower bag body 2. The lower bag body 2 is located below the upper bag body 1. A middle connecting bag 3 is fixedly connected between the outer surface of the lower end of the upper bag body 1 and the outer surface of the upper end of the lower bag body 2. Second sealing strips 8 are fixedly installed on both the left and right sides of the inner wall of the middle connecting bag 3.

[0025] The upper outer surface of the upper bag body 1 and the lower outer surface of the lower bag body 2 are both fixedly installed with bag openings 4; the upper bag body 1, the lower bag body 2, the middle connecting bag 3 and the bag opening 4 are integrally formed; a tear notch 6 is provided on the outer surface of one end of the bag opening 4; a first sealing strip 5 is installed on the inner wall of the bag opening 4; and pulling straps 7 are fixedly installed in the middle of the outer surfaces on both sides of the middle connecting bag 3.
