Abstract

The invention discloses a plastic composite membrane bag for packaging. The membrane bag comprises a body; the middle of the body is provided with a center dividing and cutting line, and easy-to-tearopenings of 11 rows time 6 columns made by adopting a shearing process are arranged on the center dividing and cutting line; left side easy-to-tear openings are formed in the leftmost side of the body, right side easy-to-tear openings are formed in the rightmost side of the body, and arc-shaped compensation edge sealing edges are arranged on the easy-to-tear openings, the left side easy-to-tear openings and the right side easy-to-tear openings correspondingly; the number of the left side easy-to-tear openings is 17, and the left side easy-to-tear openings comprise 6 edge easy-to-tear openingsand 11 secondary easy-to-tear openings; and the number of the right side easy-to-tear openings is 16, and the right side easy-to-tear openings comprise 5 edge easy-to-tear openings and 11 secondary easy-to-tear openings. According to the plastic composite membrane bag for packaging, a product is provided with the arc-shaped compensation edge sealing edges at the easy-to-tear openings, the left side easy-to-tear openings and the right side easy-to-tear openings correspondingly, so that the easy-to-tear openings are easy to find, the bag can be conveniently torn off from the position of the easy-to-tear openings, meanwhile, the sealing performance of the bag is prevented from being reduced, and the cutting waste is prevented from being generated when the easy-to-tear openings are processed.
