01 Mixture

The required raw materials are fully stirred evenly according to a certain formula through the mixer. According to the different needs of customers, study the ratio of materials, put the required raw materials into the mixer and stir to ensure uniform mixing.

02 Blown Film

After debugging the film blowing machine, put the mixed materials into the hopper of the machine. The film blowing machine blows plastic particles into a film after heating and melting. When blowing the film, the speed and inflation ratio should be well controlled.

03 Printing

Use a printing machine to print text and patterns, cover the wet plastic bag on the upper part of the printing plate, and press the plate and paper through the printing machine to transfer the ink from the concave part of the printing plate to the bag.

04 Bag Making

Blown film bags are cut using a bag cutting machine. When cutting bags, pay attention to whether the edge sealing is firm, whether there is sticky edge (overburning, excessive melting of the glue edge), and whether the cutting edge is neat.
