Converting aluminium foil for lamination
with the development of pharmaceutical industry and the improvement of product quality, the quality requirements of customers for medical aluminum foil have been rapidly improved, such as the quantity of color types of printing up, the Diversity of color, the surface quality of the foil and plate quality requirements are higher and higher; With the increase of the speed of gluing, coloring and charging equipment.
the drying temperature of gluing and coloring is increased from 140℃ to 230"260℃, which puts forward higher requirements for the heat resistance and heat sealing strength of the medicine cabinet. It is generally required that the thickness tolerance of high quality drug foil is less than 3% of the soil, the heat sealing strength is not less than 10N/15mm, good heat resistance (through the drying box, the aluminum foil is soft), no pinhole, no bright spot, no color difference and so on.
