Blister packaging and aluminum foil bags are two common forms of drug packaging, each with its own unique advantages. Blister packaging is transparent and intuitive, which makes it easy for consumers to check the status of drugs. At the same time, its tight structure can effectively prevent drugs from moisture and oxidation. Aluminum foil bags have good sealing and barrier properties, making them ideal packaging materials for solid oral preparations, powder injections and other drugs. Both packaging forms can effectively protect drugs from the external environment and ensure the quality and safety of drugs.
Heat-sealable aluminized BOPP film is a high-performance packaging material that combines the superior physical properties of BOPP film and the high barrier properties of the aluminized layer, making it the preferred material for drug packaging. BOPP film has the characteristics of light weight, non-toxicity, odorlessness, good transparency, high mechanical strength, and dimensional stability. The aluminized layer is coated with an extremely thin layer of metal aluminum on the surface of the BOPP film through a special process. This aluminized layer not only gives the film a metallic luster, but also significantly improves its barrier properties.
Specifically, the barrier properties of heat-sealable aluminized BOPP film are mainly reflected in the following aspects:
Moisture-proof performance: The aluminized layer can effectively block the penetration of moisture and prevent the drug from deteriorating due to moisture. In blister packaging and aluminum foil bags, this moisture-proof performance is particularly important, because once the drug is damp, its efficacy and stability will be greatly reduced.
Antioxidant performance: The aluminized layer can also effectively block the penetration of oxygen and prevent the drug from deteriorating due to oxidation. Oxygen is one of the main factors that cause drug oxidation. Therefore, in drug packaging, antioxidant performance is one of the important indicators for evaluating the quality of packaging materials.
Light-proof performance: The aluminized layer has good light reflection ability and can reduce the impact of ultraviolet rays on drugs. Ultraviolet rays are a strong radiation energy that will cause chemical reactions in certain components of drugs, causing the drugs to deteriorate. Therefore, in drug packaging that needs to be shielded from light, the light-proof performance of heat-sealable aluminized BOPP film is particularly important.
In blister packaging, heat-sealable aluminized BOPP film is usually used as a barrier layer between the blister plate and the drug. It can fit tightly on the blister plate to form an effective barrier to prevent the drug from direct contact with the external environment. Its good transparency allows consumers to intuitively see the status of the drug, increasing the attractiveness of the packaging.
In aluminum foil bags, heat-sealable aluminized BOPP film is one of the main materials of the bag body. It can tightly seal the bag mouth to prevent drug leakage. The high barrier properties of the aluminized layer enable the aluminum foil bag to effectively isolate external factors such as moisture, oxygen and ultraviolet rays, ensuring the stability and safety of the drug during storage and transportation.
Heat-sealable aluminized BOPP film has many advantages in drug packaging, such as excellent barrier properties, good heat sealing properties, beautiful metallic luster, and environmentally friendly recyclability. These advantages make it have a wide range of application prospects in the field of drug packaging.
However, with the advancement of technology and the improvement of consumer requirements for product quality, heat-sealable aluminized BOPP film also faces some challenges. For example, how to further improve its barrier properties to meet the demand for pharmaceutical packaging with higher barrier properties; how to optimize its heat sealing performance to improve the production efficiency and sealing of packaging; and how to reduce production costs to improve its market competitiveness.
In order to solve these challenges, researchers are constantly exploring new technologies and processes to improve the performance of heat-sealable aluminized BOPP films. For example, by optimizing the aluminizing process, the uniformity and density of the aluminized layer can be improved; by adding functional additives, the heat sealing and barrier properties of the film can be improved; and by recycling and reuse technology, the production cost can be reduced.
