Abstract

The invention discloses a packaging bag and an apparatus and a method for manufacturing film material of the packaging bag, and a method of manufacturing the packaging bag. The processing of the portable portion is conducted by the apparatus for manufacturing film material, and the prepared film material is made into a packaging bag finally. In the technical solution of the invention, by adding a handle structure on the side portion of the big-sized packaging bag, the bag structure of the invention is easy to carry or move the packaging bag and the product within the packaging bag that is large in weight, structure, and size. The packaging bag of the present invention has a simple structure, which is convenient to use and process, improving the practicality and usability of the bag.

Claims
