PVC Pharmaceutical Films For Highest Moisture Protection

June 10, 2025

The moisture-proof rigid PVC pharmaceutical films is a material specially designed for the needs of the pharmaceutical industry and is widely used in the protection of pharmaceutical packaging and medical devices. The rigid PVC film material itself has excellent mechanical strength and chemical resistance, which can effectively isolate moisture and air and prevent moisture from affecting the quality of medicines. In addition, the transparency of the material makes the medicines in the package clearly visible, which is convenient for identification and inspection.

When applied in pharmaceutical packaging, the PVC pharmaceutical films often showed in composite structure. PVC film is compounded with other materials with good moisture-proof properties such as aluminum foil and PE film to form a multi-layer composite structure. For example, the common aluminum-plastic composite film is a composite of rigid PVC film and aluminum foil through an adhesive. The high barrier properties of aluminum foil are used to effectively improve the moisture-proof properties of the overall film.

– PVC/PVDC composite film:

PVDC (polyvinylidene chloride) has extremely low water vapor permeability and oxygen permeability. After compounding with PVC, it can significantly improve the moisture-proof performance, effectively block external moisture and oxygen, and protect medicines from moisture and deterioration. It is often used for drug packaging with high requirements for moisture-proof and oxygen-proof, such as blister packaging of tablets and capsules such as some antibiotics and vitamins.

– PVC/AL/PE composite film:

Aluminum foil (AL) has excellent barrier properties and can block moisture, oxygen and light. PVC is composited with aluminum foil and PE (polyethylene), where PE plays the role of heat sealing and protecting aluminum foil, and PVC provides good printing and mechanical properties, which can make the composite film have good moisture-proof, oxygen-proof and light-shielding properties. It is often used for packaging of some injections, powder injections and other drugs.



Application field of PVC pharmaceutical films:

– Tablet packaging:

It is widely used in blister packaging of various tablet drugs, such as cold medicines, antipyretics, antibiotics, vitamin tablets, etc. It can effectively protect tablets from moisture and deformation, and it is convenient for patients to take them according to dosage.

– Capsule packaging:

It is also a commonly used packaging material for capsule drugs. Through blister packaging, it can prevent capsules from breaking and sticking during storage and transportation, and maintain the integrity and efficacy of capsules.

– Granule packaging:

For some granular drugs, rigid PVC film rolls can be made into suitable packaging containers, such as tea bag packaging or small bag packaging, which can prevent moisture and leakage and ensure the stability of granules.



Due to its excellent moisture-proof performance, PVC pharmaceutical films can effectively extend the shelf life of drugs and ensure the safety and effectiveness of drugs during transportation and storage.
