About 4 kinds of material characteristics of holographic laser film
The holographic image with rainbow dynamic and three-dimensional effect is transferred to PET, BOPP, PVC or coated substrate by molding, and then a certain laser laser effect is obtained by using composite, hot stamping, transfer and the like.
Introduction: Production process and performance characteristics of Aluminum metallised film ( I )
The aluminum coating film (metallised film) is obtained by evaporating a high-purity aluminum wire into a gaseous state at a high temperature (1100 to 1200℃) by a vacuum aluminum plating process.
How to reduce the metallized composite film spots
Metallized film often occurs in composites. The composite film has obvious white or gray spots. The distribution of spots is random and the size is irregular. The spots often appear in the printing of full white or light yellow background. Spots will improve after ripening.
