The printing speed of gravure printing is very fast, and when using line laminating processing, there is often a situation where the laminating is dry and not transparent, so it is often necessary to use the method of off-line laminating for laminating processing.

In flexographic printing, due to the relatively lower printing speed, the film is cured in the machine film well and can also be cut to the finished product in parallel.

If cationic adhesive film is used, it is easy to reduce the residual solvent content per square meter to a very low level. This type of laminating adhesive can now be used on materials such as polyethylene and polyether metal sheet substrates.

The vast majority of shrink film printing is completed by gravure printing, with a very small number using flexographic printing. Nowadays, solvent based inks are mainly used for shrink film printing.

Although UN curing ink can also complete the printing of shrink film without solvent evaporation, the adhesion of UV ink is poor when the shrinkage reaches 70%.

And cationic ink has passed this required test, becoming a unique ink system for OPS, PVC, and OP materials.
