Reasons, countermeasures and effects of BOPP film slitting quality ---
Another reason for the burrs is the quality of the parent roll.
First, when the mother roll product is wrinkled, the burr phenomenon is likely to occur when the film is cut to the sipe roll and the film is not effectively flattened;
Second, when the film is thick or thin for a long time, the film is prone to burr phenomenon when the film is not attached to the sipe, especially in the triangular position of the thickness. In addition, since the thinner the film, the lower the stiffness, and the higher the chance of burrs.
The basic knowledge of the slitting machine and its development process --
Basic knowledge and development of slitting machine
In the modern packaging industry, the slitting machine is a relatively important equipment that is often used before and after printing. The raw materials are mainly cut before printing, such as paper, plastic film and so on. This is a process that raw material manufacturers must complete in order to meet the width requirements of packaging manufacturers such as customers. The slitting machine is used to divide the printing and composite film of a plurality of sets of patterns of a fixed width into a finished film roll to adapt to the subsequent automatic packaging and bag making process.
With the improvement of flexible packaging automation and consumer goods manufacturers focusing on reducing the inefficiency and pollution of intermediate links, some manufacturers have gradually changed the process and replaced manual packaging with more automated automatic packaging lines. As the demand for coils continues to increase, the position of the slitter is becoming more and more important, and higher requirements are placed on the efficiency of the slitter.
Domestic cutting machine development status and outlets ---
three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:
1. Frame structure: Whether it is a slitting or a second or third slitting, domestic slitting machine manufacturers should invest their energy and study on the frame structure, and actually design a more reasonable slitting machine to get rid of the cutting machine manufacturers. At present, the plagiarism of the slitting machine produced, the research and design of a personalized slitting machine, making the different materials in the structure more detailed, in the next round of international market competition, to provide a favorable weapon for film-making enterprises, At the same time, I also find out the blue ocean for my own company.
