The medicinal aluminum foil is uneven in thickness and has low tensile strength. The thickness of the aluminum foil is uneven, and the amount of the adhesive coating is difficult to reach the standard in the medicine foil printing process, so that the difference in the coating amount becomes large, thereby affecting the heat sealing strength of the aluminum foil and the plastic hard sheet; the thickness is uneven, and the tensile strength is low. After the tension is applied to the release roll, the foil is broken, which is not conducive to the normal printing.
These problems require the attention of raw material manufacturers. At present, with the rapid development of aluminum foil packaging for pharmaceuticals and the continuous modification of medicinal aluminum foil printing machinery in China, the development of pharmaceutical aluminum foil packaging is very rapid, except for the use of pharmaceutical tablets and capsules. In addition to packaging and printing, it will also be widely used for external packaging printing of injection kit drugs.
