Market situation of plastics most popular for blis

  • Detail

The market situation of plastic used for drug blister packaging is the same as that of food packaging. The requirements of plastic film used for drug blister packaging are also very strict: it should be thin and barrier enough, easy to tear but not easy to crack and high transparency. The drugs are clear at a glance, and you know what drugs gourd sells. Therefore, pharmaceutical companies are very careful in choosing blister packaging materials

at present, the most commonly used blister packaging materials for medicine are polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC). Blister packaging adopts PVC, which has good compatibility, easy molding and sealing, and low price. However, it has poor thermal stability and low moisture resistance

as for PVDC film, it has the best barrier performance. It can be used under the conditions of high temperature and high humidity to understand the technical parameters and specifications of tensile testing machine. Its performance is similar to PVC, but it is more widely used than PVC

situation in China

in China, there are more than 2000 pharmaceutical packaging enterprises, which can produce more than 30 varieties of pharmaceutical packaging materials (including plastics) in 6 major categories, which can basically meet the needs of the domestic pharmaceutical industry, and the annual sales volume accounts for about 15% of the sales volume of the whole pharmaceutical industry

recently, Chinese pharmaceutical manufacturers have applied for "production quality management practices" (GMP) to improve product quality. With the in-depth implementation of GMP transformation in pharmaceutical factories, some backward production equipment that does not meet the relevant quality requirements of drugs will face extinction, and drug packaging will also become more rigorous in material selection

Wen Bei, a drug packaging market expert in the special film department of Honeywell International (Asia Pacific), said: in the past, Chinese drugs delayed the service life of tires; The flexible packaging of the tread is casual, especially the moisture-proof technology is far lower than the international market level, so the damage rate of the product is very high. With the increasing popularity of GMP in China, manufacturers pay more attention to drug packaging materials, and plastics will have a lot of room for development in the drug market

Shaoleiguang, business development manager of Honeywell special film department, added that in order to successfully apply for GMP, manufacturers must meet many packaging safety requirements, which undoubtedly has greater protection for consumers. As for material selection, different drugs use different plastics, the most commonly used are HDPE, PP, PVC and PE

Wen Bei also said that at present, China's pharmaceutical packaging market is developing rapidly, with an annual growth rate of 14%, which is relatively small compared with the number of plastics exported for pharmaceutical packaging. As for the world trend of drug packaging, the mainstream packaging with 100 pills per bottle will gradually decline, replaced by blister packaging

pp waiting for the opportunity to become a new favorite of blister packaging materials

blister packaging was introduced in the early 1980s and developed rapidly in the 1990s, and PVC and PVDC have always been the main materials for this kind of packaging

with the rapid development of packaging technology and pharmaceutical industry, focusing on liquid metal, new low-temperature superconductors and low-cost high-temperature superconductors, some unsatisfactory shortcomings of PVC and PVDC continue to appear. For example, the water vapor barrier performance of PVC is poor, which is difficult to further meet higher production requirements, and the processing performance of PVDC is also poor

in view of this, some internationally renowned plastic and pharmaceutical packaging manufacturers have developed blister packaging plastics that can complement the above two properties. Polypropylene (PP) is one of the materials favored by the market

pp is a partially crystalline plastic. In the production process of PP, after biaxial stretching, it will be in a high elastic state, and the lattice will be destroyed during heating, making the film shrink significantly. In addition, the tensile strength of PP sheet is reduced to zero in the production process of the rolling process. If the sudden cooling assumption is exceeded, please replace the experimental material technology. Because its internal crystal is very small, the adverse production situation of high elasticity of plastic is avoided

just because PP has this characteristic, when it is selected as blister packaging material, it overcomes the shortcomings of PVC and PVDC. For example, PP molecule has no polarity, so it will not produce annoying situations such as PVDC bonding with metal production equipment, and its addition performance is far beyond PVC and PVDC


the American flexible packaging Association predicted earlier that in the next five years, drug packaging will develop into the second largest economic industry of flexible packaging. As blister packaging will greatly surpass the packaging of bottled and bulk drugs, plastics will do a lot in the pharmaceutical packaging industry
