High quality blister aluminium foil printed

Haomei supply high quality blister aluminium foil printed in large rolls, the alloy is 8011 and 8021, the thickness is 0.02-0.075mm. The method of making medicinal aluminum foil packaging is to print the printed aluminum foil on the special printing and coating machine. In the production process, it is necessary to develop and control the printing materials and the inspection method of the blister aluminum foil material to facilitate the product quality in the process of printing.

Pinholes and detection of medicinal aluminum foil. Aluminum foil has a highly dense metal crystal structure, theoretically, blister aluminum foil can completely block any gas, water vapor and light, but in fact, due to the use of rolling method in the production process, the quality of the oil, the condition of the surface of the rolling roller, the process technology and the environment of the production site, etc., the thinner the aluminum foil is rolled, the inevitable defects occur. Pinhole is one of the most important defects, the size and number of pinholes are one of the important yardsticks for measuring the quality level of blister aluminium foil products. It is also because of the presence of pinholes that the amount of oxygen, water vapor, etc. to the aluminum foil is not zero. The size and number of pinholes in aluminum foil have a decisive influence on the moisture resistance, gas barrier properties and opacity of aluminum foil and its composite materials.

Detection of the bursting strength of blister aluminium foil printed. In the printing production process, if the intrinsic quality of the pharmaceutical blister aluminum foil is poor, the aluminum foil is broken and cracked frequently in the production, which affects the continuity of the printed pattern characters, and the coating is also unable to proceed.
