The blown film printing integrated machine is a device that can combine the blown film and printing processes together. It is mainly used to produce various plastic packaging bags, such as supermarket shopping bags, garbage bags, clothing bags, etc., with high efficiency and one-time molding. ‌‌
What can this machine do
The biggest feature of this machine is its "one-piece" design, where plastic particles enter and produce a film roll with printed patterns, eliminating the need for separate machines. ‌‌
Applicable materials: The main food is polyethylene based raw materials, such as low-density polyethylene (LDPE) and high-density polyethylene (HDPE), which can be used.
The products produced are widely used in civil and industrial packaging fields such as food packaging, clothing bags, garbage bags, vest bags, etc.
Workflow: First, heat and melt the plastic particles, blow them into a thin film, cool and shape them, then directly print them, and finally roll them up. ‌‌
What are the sizes of common models
The model names of different manufacturers are different, but mainly depend on the screw diameter and blown film width. The following are several common specifications on the market for reference:
Mini machine (such as 45/600 type): screw diameter of 45 millimeters, blown film width of 600 millimeters, main power of approximately 11 kilowatts, suitable for making small-sized bags.
Medium sized machines (such as 55/800 type): screw diameter of 55 millimeters, blown film width of 800 millimeters, main engine power of about 15 kilowatts, and output slightly higher than small-sized machines.
Large scale machine (such as 60/1000 type): screw diameter of 60 millimeters, blown film width of 1000 millimeters, main engine power can reach 18.5 kilowatts or more, suitable for large-scale production.
Printing accuracy: The general overprint accuracy is around 0.2 millimeters in both horizontal and vertical directions, which can meet the printing requirements of ordinary packaging bags. ‌‌
