Production Process

Plastic pellets are fed into an extruder though a hopper. Heat and friction from the extruder convert the pellets into a continuous uniform melt and force this melt through a die to form into a continuous profile. Air from inside and outside blow onto this profile to cool it and makes it to be blown up like a bubble. The bubble then moves vertically upwards, until it is flattened into a lay-flat tube by nip rollers. This lay-flat tube is then taken back down the extrusion tower via more rollers, and finally, it will be taken up by a winder.

Various blown film machines in our plant can meet your different demands of sizes. Our blown film lines are capable of lay-flat tube width to 3200mm.

Rotogravure printing is a manufacturing,in which the film is printed by a gravure cylinder that has been engraved the printing design. At the start of this process, a blade on the printing machine removes the excess ink from the non-recessed areas of the cylinder surface.

Then the film passes between the gravure cylinder and impression roller where force is applied on the film in order to transfer the printing design from the gravure cylinder onto the film.

Finally, the film goes through a dryer because it must be completely dry before going through the next color unit and accepting another coat of ink.

Three series of printing lines in our CMP Plant are capable from one-color printing to seven-color printing.

Heat sealing is a process of sealing one thermoplastic material to another thermoplastic material with heat and pressure.

The tube film will be closed by heat sealing process and then cut into individual bags in this process.

Our bag making lines are capable of producing big-size flat bags,square bottom bags or other shapes of bags with maximum width of 2,000mm.
