The quality of aluminium foil is often measured by the size and number of pinholes. The effects of oxygen and water vapour on aluminium foil are often not completely isolated due to pinholes. Aluminium foil has moisture resistance, light shielding and gas barrier properties, and the most important factor affecting these properties is the size and number of pinholes in the aluminium foil.

National standard GB3198-1996 rules to pinhole size and how many are as follows: the aluminum foil surface with visible light is allowed in the pinhole, but not dense, pinhole medicinal aluminum foil pinhole shall not be greater than 0.3 mm in diameter, and no more than 5 / m2, other industrial pure aluminum foil pinhole size must not exceed 0.5 mm biggest [5]. Raw material of aluminum foil production and inspection according to the "aluminium and aluminium alloy foil" national standard of GB/T3198-2003 [6]. The standard for raw aluminum foil pinhole degree of related statements are as follows: the pharmaceutical packaging alfoil pinhole diameter should not be larger than 0.3 mm, and also no more than 5 / m2.
The above-mentioned medical packaging aluminium coil refers to the raw material aluminium foil used in the production of PTP aluminium foil,this expression provides the raw material aluminium foil pinhole degree of two standard values: 1, pinhole diameter should not be more than 0.3mm; 2. Not more than 5 pinholes /m2 with a diameter less than 0.3mm. In the current PTP aluminium foil production, inspection based on the industry standard YBB00152002 pinhole degree of the relevant provisions are as follows: 1, the diameter of more than 0.3mm pinhole is not allowed; 2. the number of pinholes with a diameter of 0.1~0.3mm shall not exceed 1 (the number of pinholes less than 0.1mm is not specified). With the continuous improvement of the production process of domestic raw aluminium foil manufacturers, the overall quality of raw aluminium foil is steadily improving, and the internal control standard of aluminium foil pinhole degree of some enterprises has met the requirements stipulated in YBB00152002; however, more aluminium foil products produced by enterprises still have a long way to go in terms of pinhole quality stability.
The most fundamental reason is that only with a complete production chain from raw material to aluminium foil, it is easy to carry out comprehensive quality control of aluminium foil production process and establish a complete production and quality control system. At present, most aluminium foil raw material manufacturers do not have a coil material production line. They cannot carry out real effective quality control on the main production link of pinhole - bad material, and can only passively avoid other quality problems in the subsequent rolling and scuttling process.
