Modification of the traditional model of the photoelectric system, in the heat sealing, printing before the installation of multiple sets of equipment, so that the system feeding flat, smooth (even if it is not too thin material does not wrinkle, do not discount) to improve the heat sealing and printing quality.

At the same time, the transmission system of the machine is also improved. The main transmission system comprises a friction drive for direct transmission. The system runs smoothly and reasonably, and eliminates the relative sliding. Plastic film blowing machine so that the heat transfer line on the line, the production of higher reliability.
