Shao Leiguang, Business Development Manager of the Special Film Department, and Wen Bei, Market Expert of the Special Film Department of Honeywell International (Asia Pacific) Company in the pharmaceutical packaging market: For food packaging, the plastic film used for pharmaceutical blister packaging has very strict requirements: thin enough, good barrier, and easy to tear but not easy to crack and high transparency. Therefore, pharmaceutical companies are very careful when selecting materials for blister packaging.

Experts discuss the plastic application of bubble wrap packaging

Shao Leiguang, Business Development Manager of the Special Film Department, and Wen Bei, Market Expert of the Special Film Department of Honeywell International (Asia Pacific) Company in the pharmaceutical packaging market: For food packaging, the plastic film used for pharmaceutical blister packaging has very strict requirements: thin enough, good barrier, and easy to tear but not easy to crack and high transparency. Therefore, pharmaceutical companies are very careful when selecting materials for blister packaging.

The most commonly used pharmaceutical blister packaging materials at present are polyvinyl chloride sheets (PVC) and polyvinylidene chloride (PVDC). The blister packaging is made of PVC, which has good compatibility, is easy to form and seal, and is cheap. However, it has poor thermal stability and low moisture resistance. As for PVDC film, it has the best barrier performance and can be used under high temperature and humidity conditions. Its performance is similar to PVC, but it is more widely used compared to PVC in terms of application.

In China, there are nearly 2000 pharmaceutical packaging enterprises that can produce 6 types and over 30 varieties of pharmaceutical packaging materials (including plastics), which can basically meet the needs of the domestic pharmaceutical industry. Annual sales account for about 15% of global pharmaceutical industry sales. Recently, Chinese pharmaceutical manufacturers have applied for the "Production Quality Management Regulations" (GMP) to improve product quality. With the deepening of GMP transformation in pharmaceutical factories, some outdated and non compliant production equipment will be phased out, and drug packaging is becoming increasingly rigorous in material selection. Wen Bei said: 'In the past, the packaging of Chinese drugs was casual, especially in terms of moisture-proof technology, which was far lower than the international market level, resulting in a high rate of product damage.'. With the increasing popularity of GMP in China and the increasing emphasis on pharmaceutical packaging materials by manufacturers, plastics will have great development space in the pharmaceutical market

Shao Leiguang, Business Development Manager of Honeywell's Special Film Department, added: 'To successfully apply for GMP, manufacturers must meet many packaging safety requirements, which undoubtedly provides greater protection for consumers.'. As for material selection, different drugs use different plastics, and the most commonly used ones are HDPE, PP, PVC, and PE

Wen Bei also stated that the current pharmaceutical packaging market in China is developing rapidly, with an annual growth rate of 14%. Therefore, the quantity of plastic used for pharmaceutical packaging exported from other regions is relatively small. As for the global trend of drug packaging, mainstream packaging with 100 capsules per bottle will gradually decline and be replaced by bubble wrap packaging.

Bubble packaging was introduced in the early 1980s and rapidly developed in the 1990s, with PVC and PVDC being the main materials for this type of packaging.

With the rapid development of packaging technology and the pharmaceutical industry, some unsatisfactory shortcomings of PVC and PVDC continue to emerge. For example, the water vapor barrier performance of PVC is poor, making it difficult to further meet higher production requirements, and the processing performance of PVDC is also poor.

It can be seen that some internationally renowned plastic and pharmaceutical packaging manufacturers have developed blister packaging plastics that can supplement the above two properties, and polypropylene (PP) is one of the more popular materials in the market. PP is a partial junction
