Some pharmaceutical companies are more willing to use PP packaging for blister packaging materials - blister packaging materials, pharmaceutical packa
As Food Package For pharmaceutical blister packaging, plastic Film Requirements are very strict: to both thin and has barrier properties, but also easy to tear it difficult to crack and transparent, medicine at a glance. Therefore, Pharmacy Companies are very careful in choosing blister packaging materials.
Present, the most common medical use of blister Packaging Materials For polychlorinated Ethylene Film ( PVC ) And polyvinylidene chloride (PVDC) film. Blister packaging use PVC, whichever is compatible with good performance, and easy to shape and sealed, low price; However, poor thermal stability, moisture-proof barrier is also low.
The barrier properties of PVDC film is a film the best it can under the conditions of high temperature and high humidity the use of the same performance and PVC, but in the application of more extensive than the PVC.
Situation in China In China Pharmaceutical Packaging More than 2,000 enterprises, can produce more than 30 varieties of six major types of drug packaging materials (including plastics), has been basically able to meet the needs of the domestic pharmaceutical industry, pharmaceutical industry-wide sales of approximately 15% of sales. Recently, Chinese medicine manufacturers have to apply GMP to improve product quality. With the transformation of pharmaceutical GMP in depth, some backward, and does not meet the quality requirements of the Health and pharmaceutical health facilities would face elimination, and drug packaging materials, choice of material is also in increasingly stringent. Honeywell
(Honeywell) International (Asia Pacific) Department of pharmaceutical packaging market specialty films Expert Wen North said: "In the past, the Chinese pharmaceutical packaging casually, especially in damp areas of technology far below international market levels, so the product failure rate is high. With the growing popularity of GMP in China, companies increasingly pay attention to the drug packaging materials, Plastics in pharmaceutical market will have a huge space for development. "
Honeywell Specialty Films Division Business Development Manager Shaolei Guang added: "To successfully apply for GMP, manufacturers must meet a lot of packaging Security Requirements, which is no doubt Consumption Who have greater protection. As for the choice of materials, different drugs with different plastics, the most commonly used is HDPE , PP , PVC and PE.
Man North has Table Said that China's current rapid development of pharmaceutical packaging market, the annual increase of 14%, so the relative output field for the number of pharmaceutical packaging, plastic small. The trends in the development of pharmaceutical packaging, Mei Pingzhuang 100 pieces of mainstream packaging will be gradually reduced, replaced by a blister packaging. "
PP blister packaging materials into the new darling of opportunistic Blister packaging in the early 20th century and published 80 to 90 years rapid development, but PVC and PVDC have been the main material of this package. With the packaging technology and the rapid development of the pharmaceutical industry, PVC and PVDC some shortcomings continue to show weaknesses. For example, water vapor barrier properties of PVC poor, finds it difficult to further meet higher production requirements, and processing properties of PVDC is not good. Therefore, some internationally renowned manufacturer of plastic and pharmaceutical packaging, developed to complement the performance of more than two plastic blister packaging, poly Propylene (PP) is one of the most popular material by the market. As a part of the crystallization of PP plastic. PP in the production process, after a two-way stretch, it will be in high-elastic state when heated character will be destroyed, so obviously shrink film. In addition, PP sheet production technology in the extension of the process of pressure, stretch reduced to zero, if the technology with the sudden cold, because of its small internal crystals, avoid the plastic was high-elastic state of the unfavorable production.
Is because PP has this feature, it was selected as the blister packaging materials, PVC and PVDC overcome the shortcomings, such as PP molecules do not have polarity, they will not produce, such as PVDC and the annoying metal bonding equipment case, the performance is far beyond the PVC and PVDC.
Conclusion:
U.S. Flexible Packaging Association than predicted over the next five years, the medical packaging will become the second largest economy flexible packaging industry. As the blister packaging will surpass that of bottled and bulk drug packaging trend, plastic packaging in the pharmaceutical industry will be as big.
