I. Introduction:
This film blowing and printing machine is used for producing softplastic package bag, it can blow and print at the same time withprinting in both sides, the material is HDPE, LDPE, dissolubleplastic and recycle material etc. It is the best machine forshopping bags(vest bags). The main features are as follows:
1. Wide application, several purposes(It can blow HDPE and LDPE,blowing and printing at the same time, or single blowing and singleprinting);
2. Advanced structure, easy operation, correct overprint, easymaintenance;
3. Saving raw material, reliable quality. It has followingadvantages which we compared with same line machines:
A. Bright color, strong fastness;
B. Blowing and printing at the same time, exact overprint;
C. Easy maintenance, reliable and stable quality;
D. Less power consumption, labor, working time and cost, etc.
