Medicine is a special product with high added value and high safety and reliability requirements. Except for packaging of traditional Chinese medicine pieces and low-grade granules, the composite film of medicine packaging is mainly made of pure aluminium foil composite material, while food packaging is generally still made of transparent or low-grade granules. Aluminised packaging mainly.

Due to the high barrier properties of aluminium foil laminates, the previously neglected side penetration can no longer be ignored. In addition to considering penetration through the packaging material, the aluminium foil composite bag should also consider penetration through the heat-sealed edge of the bag. The heat-sealed edge should have sufficient width, and the heat-sealing material used must have certain barrier properties. The author once took an aluminium foil composite film with a water vapour transmission rate of 0.25g/m2-24h (cup method 38℃RH90%) to make a bag, and sealed the fully dried anhydrous calcium chloride in the bag to measure the weight gain, which lasted for a period of time.
In 2010, the water vapour transmission rate of the aluminium foil composite film was 0.0014 g/m2-24h when the sealing edge width was 8 mm, and the water vapour transmission rate of the aluminium foil composite film was 20 mm when the sealing edge width was 20 mm. The transmission rate is only 0.0008 g/m2-24h. It can be seen that the seal width has an effect on the barrier properties of the aluminium foil laminate bag. Further experimental results show that when the thickness of the aluminium foil is more than 15µm, the barrier property of the aluminium foil composite bag is completely determined by the width and quality of the edge seal.
