PVC blister packaging has many functions in pharmaceutical packaging, mainly including protecting pharmaceuticals, preventing pollution and extending shelf life.
The main functions of PVC blister packaging include:
Protecting pharmaceuticals: PVC blister packaging can effectively prevent pharmaceuticals from being contaminated, damp, ineffective and damaged. Pharmaceuticals are very sensitive to moisture, humidity and light, and are easily deteriorated or ineffective. PVC materials have good barrier properties to water, steam, light, etc., and can protect pharmaceuticals from the influence of the external environment.
Extending shelf life: PVC blister packaging can effectively isolate oxygen and moisture through its excellent barrier properties, thereby extending the shelf life of pharmaceuticals. This packaging material can protect pharmaceuticals from interference from the external environment during storage and transportation, ensuring the stability and effectiveness of pharmaceuticals.
Low cost and high performance: PVC materials have low cost and are suitable for large-scale production. In addition, PVC blister packaging also has anti-theft, anti-tampering and good protection functions, which can prevent pharmaceuticals from being illegally opened or tampered with.
Use with other materials: In order to further improve the barrier properties of PVC blister packaging, it is usually used together with materials such as PVDC (polyvinylidene chloride). PVDC has good moisture-proof and barrier properties, which can further protect drugs from moisture and oxygen.
