Composite flexible packaging industry is effected by the quantity of cement and coating

Published :2012/7/31 14:37:37 | information source:

The quantity of cement is insufficient, uneven coating will directly influence the film laminated surface adhesion relay, further influence composite strength, this in the use of hot melt adhesives ca is most appear, cannot be ignored.

The quantity of cement and how many of the following a few factors:

1 anilox roll of nets hole volume, this factor is decisive. If anilox roll no-blockage, adhesive proportion of high 

concentration,base material tension value appropriate, the quantity of cement is moderate, composite membrane composite strength is still not ideal, should consider to replace anilox roll, in order to increase the quantity of cement, lines roller general specification has 80 μ m, 100 μ m, 120 μ m, 140 μ m, and so on, can be adjusted according to the actual complex or choice;

2 solvent ratio concentration. Increase the concentration ratio in order to improve the agent the quantity of cement;

3 anilox roll is blocked. If the jam, can clean or replace glue anilox roll.

Coating is the basement membrane uneven may be apparent quality is bad, scraper and existing gap anilox area of the jam, and many other factors.
