Abstract:
1. A packing method using an air evacuative binding type air packing bag, comprising: providing two inner films; stacking two outer films to allow the two inner films to be positioned between the two outer films; hot-sealing the two outer films and the two inner films, forming at least one air cylinder between the two outer films, forming an air filling passageway at one side of the at least one air cylinder, forming at least one air inlet by not adhering the two inner films to each other so that the at least one air inlet is defined between the two non-adhered inner films, each air inlet corresponding to each air cylinder, forming at least one hot sealing point in the air filling passageway, and sticking one of the two outer films to one of the two inner films through the at least one hot sealing point; filling air into the air filling passageway so that the two outer films are pulled outward and the outwardly pulled outer films drive the two non-adhered inner films to pull apart outward through the at least one hot sealing point to open the air inlet, and allowing the air to be filled in the air cylinder via the opened air inlet; bending the air cylinders to form a first cushioning wall and a second cushioning wall; hot-sealing two sides of the first cushioning wall and the second cushioning wall to form an accepting space; placing an article in the accepting room; and drawing air out of the accepting space to allow the first cushioning wall and the second cushioning wall to bind the article up.
