Sterilization Resistance and coating firmness of Aluminium-plastics Combination Caps for Antibiotics Bottles
Sterilization resistance and coating firmness of aluminium-plastics combination caps for antibiotics bottles
According to the test items of ybb00372003-2015 for the aluminum-plastic composite cover for antibiotic bottles in the national standards for pharmaceutical packaging materials, the testing methods for sterilization resistance and coating firmness are as follows :
[sterilization resistance] take appropriate amount of aluminium- plastics combination caps, put it on the appropriate bottle with marked water capacity (add rubber plug), and seal it with sealing device. After sealing , keep it in the steam sterilizer for 30 minutes at 121 ° c ±2 ° c , including 130 ° c ±2 ° c for 5 minutes. After sterilizing the bottle cap , the plastic parts can withstand the steam sterilization temperature of 130℃ without deformation and discoloration . The surface of the aluminum parts should not change significantly. The cap should be free from fracture and abnormal deformation.
[coating firmness] take appropriate amount of aluminium-plastics combination caps (coated on outer surface),After 30 minutes of steam sterilization at 121 ° c ±2 ° c, including 130 ° c ±2 ° c for 5 minutes, the plastic parts were removed, and the absorbent cotton soaked with 80% (V/V) ethanol solution was used to wipe the surface for 30 seconds, and then the absorbent cotton soaked with 70% (V/V) isopropanol solution was used to wipe the surface for 30 seconds. The coating should have no wear.
