The size and quantity of pinholes are one of the important metrics to measure the quality of the PTP aluminum foil. The aluminium foil jumbo roll manufacturer tells you how to do.

The blister packaging of medicines is made up of PTP aluminum foil, PVC, printing inks, protective agents, adhesives, etc. For pharmaceutical packaging, aluminum foil is the only metal packaging material.

As a printing material, PTP foil is non-toxic, odorless, of excellent electrical conductivity, light-shielding properties, extremely high moisture resistance, gas barrier properties and taste retention properties, which is a packaging material that has not yet been replaced.

Theoretically the perfect aluminum foil can completely block any gas, water vapor and light, but in fact, due to the rolling process used in the production of aluminum foil, the quality of the rolling oil, the surface condition of the rolling roll and the processing environment, the various defects will inevitably appear.

Pinholes are the most serious defects. The size and quantity of pinholes are one of the important metrics to measure the quality of the medical aluminum foil. How to improve the quality of aluminum foil and reduce the number and size of aluminum foil pinholes is an urgent problem for domestic aluminum foil manufacturers to solve.

To ensure the PTP aluminum foil, we have to inspect the pinholes of the finished medical aluminum foil. The method is: use a pinhole inspection table. Take 20 pieces of aluminum foil with the size of 400 mm × 250 mm and place them on the pinhole inspection table one by one, and check the pinholes in the dark.

The requirements for pinholes are: there should be no dense, continuous and periodic pinholes, and no pinholes with a diameter greater than 0.3 mm. There should be no more than 1 pinholes per square meter.

In addition, it is necessary to sample the rupture strength value of the aluminum foil. The testing instrument uses a rupture strength meter. The method is to take three pieces of 40 mm X 40 mm samples from the finished aluminum foil and put them into the gap of the instrument, turn on the oil pump and measure the pressure gauge. The rupture strength value should be greater than 98kpa.
