Why is barrier property so important for medicine package?
Publish Time: 2025-07-01
Medicine package plays a vital role in the pharmaceutical industry chain. It is not only the "outer coat" of medicines, but also a key link to ensure the quality, safety and effectiveness of medicines. High-quality medicine package materials must have good stability and barrier properties to ensure that the medicines are protected from external environmental factors during the entire storage, transportation and use process, so as to maintain their original physical and chemical properties and efficacy.
First, medicine package materials should have extremely high physical stability. In actual applications, medicines may experience vibration, extrusion and changes in temperature and humidity conditions during transportation, so the packaging materials must be strong and durable, not easy to break or deform. High-quality materials such as high-density polyethylene (HDPE), polypropylene (PP) or aluminum-plastic composite film not only have excellent mechanical strength, but also have good temperature resistance, can maintain structural integrity in various complex environments, and provide continuous protection for medicines.
Secondly, medicine package must have excellent barrier properties. Factors such as oxygen, moisture, and light are the main external threats to the stability of medicines. For example, some drug ingredients are prone to failure due to oxidation, or deterioration or even microbial growth after being damp. High-quality medicine packages adopt a multi-layer composite structure design, combined with high-barrier materials such as aluminum foil, EVOH (ethylene-vinyl alcohol copolymer), etc., which can effectively block the intrusion of water vapor, oxygen and ultraviolet rays, extend the shelf life of drugs, and ensure that they are always in a safe and stable state during the validity period.
In addition, medicine packages must also take into account both sealing and safety. Good sealing performance can prevent drugs from being contaminated or leaking during storage or transportation, especially for highly sensitive drugs such as injections, oral liquids, and powders. At the same time, modern medicine packages pay more and more attention to anti-counterfeiting and traceability functions, and improve recognition capabilities through QR codes, RFID chips, laser holographic patterns, etc., to prevent counterfeit drugs from entering the market and ensure consumer drug safety.
With the popularization of environmental protection concepts, green sustainability has also become an important direction for the development of medicine packages. More and more companies are beginning to use recyclable, low-VOC emission environmentally friendly materials to reduce environmental impact while ensuring functionality. This trend not only conforms to the global background of energy conservation and emission reduction, but also enhances the social responsibility and brand image of pharmaceutical companies.
From the perspective of user experience, modern medicine packages continue to optimize the opening method, label clarity and ease of use, especially when targeting the elderly or special groups, and pay more attention to humanized design, such as easy-to-tear edges, large-font printing, voice prompt packaging, etc., to further improve medication compliance and safety.
High-quality medicine packages fully guarantee the quality and safety of medicines with their excellent physical stability, efficient barrier performance, reliable sealing protection, environmentally friendly and sustainable material selection, and humanized use design. It is not only an indispensable component of medicines, but also a bridge of trust between producers and users.
