Abstract

The invention discloses a thin-film flexible packaging bag. The thin-film flexible packaging bag is formed from thin films through hot-pressing and cutting, and provided with a bag body and a water outlet tube integrally formed with the bag body, wherein the lower end of the water outlet tube is communicated with the bag body. The thin-film flexible packaging bag is simple to produce and low in cost; when the thin-film flexible packaging bag is in a natural state after being filled with a liquid, the thin films forming the water outlet tube are closely bonded, the liquid in the bag body cannot leak, and a leakproof function is achieved; when the thin-film flexible packaging bag is not filled with the liquid and after the liquid is poured, the flexible packaging bag is small in size, and convenient to store and transport. The thin-film flexible packaging bag is capable of being widely used for packaging beverages, drinks, washing products, seasonings, medicines, industrial liquids, slurries, pastes and the like, and capable of reducing the production costs, warehouse costs and transport costs of the products.

Description
