Abstract

The invention discloses a long-barrel plastic film bag for a garbage can and a packaging method and a packaging mold of the long-barrel plastic film bag. The long-barrel plastic film bag comprises a long-barrel plastic film bag body and an outer package, wherein the outer package is a film barrel material, the film barrel material comprises a first opening and a second opening, an annular first groove is formed between the first opening and the second opening, one end of the long-barrel plastic film bag body is an open end, the other end of the long-barrel plastic film bag body is a sealed end, the long-barrel plastic film bag body is folded towards the open end and stored in the first groove, the sealed end of the long-barrel plastic film bag body extends out of the first groove of the film barrel material, and the first opening of the film barrel material, the long-barrel plastic film bag body and the second opening of the film barrel material are fixedly connected through a connecting line. According to the scheme, the film barrel material serves as a packaging container of the long-barrel plastic film bag, packaging is simple, compressibility is achieved, and the comprehensive cost is low; and the effective volume for storing the long-barrel plastic film bag body is increased, the frequency of replacing the long-barrel plastic film bag is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of plastic film bag packaging, in particular to a long-tube plastic film bag for trash cans, a packaging method, and a packaging mold.
