Differences between PVC and medical PVC

What is PVC? PVC is the abbreviation of polyvinyl chloride (PolyvinylChloride), which is a non-toxic, odorless white powder. PVC has high chemical stability, good plasticity and excellent electrical insulation. PVC y tế (polyvinyl clorua) is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator and is widely used in medical devices and medical equipment. Medical PVC has excellent mechanical strength, biocompatibility, non-toxicity, easy coloring, good chemical stability, chống lạnh, radiation resistance and good electrical insulation.

What does pvc stand for in medical terms?
In medical terms, PVC usually stands for premature ventricular contraction. This refers to an abnormal heart rhythm caused by premature electrical activation of the ventricles, which disrupts the normal rhythm of the heart. PVC is usually harmless, but if it occurs frequently, it may be a sign of underlying heart disease.

PVC for medical use is a material, which is very different from pvc meaning medical. Medical PVC is mainly used to make packaging materials for medical devices and medical equipment. Ví dụ, it can be used as a manufacturing material for medical devices such as infusion tubes, catheters, and puncture needles. These medical devices usually need to have good biocompatibility and chemical stability to ensure safety and effectiveness during use.

Medical advantages of medicinal PVC

PVC dược phẩm, đó là, medicinal polyvinyl chloride (Polyvinyl clorua) material, has significant advantages in the field of pharmaceutical packaging.

Excellent physical properties of medicinal PVC

Wear resistance and tear resistance: Pharmaceutical PVC material has good wear resistance and tear resistance, which means that it can effectively prevent damage to the packaging during transportation and storage, thereby ensuring the integrity of the medicine.
Compression resistance and impact resistance: PVC material also has excellent compression resistance and impact resistance, which can maintain the stability of its shape and structure in various environments, further protecting medicines from external pressure or impact.
Flexibility and folding strength: PVC sheets have good flexibility and folding strength, and can resist extrusion and deformation from external forces, ensuring that drugs remain intact and pollution-free during packaging and use.

Good chemical stability

Acid and alkali resistance: PVC material has strong resistance to common pharmaceutical ingredients such as acids and alkalis, and can effectively prevent chemical reactions between drugs and packaging materials, thereby ensuring the chemical stability of the drugs.
Oxidation resistance and corrosion resistance: PVC material also has good oxidation resistance and corrosion resistance, and can resist the erosion of oxidants, reducing agents and other substances, further extending the shelf life of medicines.

Biocompatibility

PVC materials are widely used in the medical industry, such as preparing hoses, infusion bags and other medical devices and equipment that come into contact with the human body. This is due to its good biocompatibility, đó là, PVC materials will not cause allergic reactions or other adverse effects in the human body, thus ensuring the safety and reliability of drugs during use.

Easy to process and low cost

Easy to process and mold: PVC material has good plasticity and processability, and can easily carry out various processing and molding operations, such as extrusion, injection molding, vân vân., thereby meeting the diverse needs of the pharmaceutical packaging field.
Low price: Compared with other high-performance packaging materials, PVC materials have lower production costs, which can save costs and improve economic benefits for pharmaceutical companies.

Wide range of applications

Medicinal PVC materials are widely used in the field of pharmaceutical packaging due to the above advantages, such as blister packaging, medicine bottle labels, seals and medicine bags, vân vân. These packaging forms can not only effectively protect medicines from the external environment, but also improve the convenience of storage, transportation and use of medicines.

Application types of pharmaceutical PVC in drug packaging

PVC is a cheap and mechanically good plastic with high strength and rigidity, and can effectively resist the penetration of oxygen and water vapor. Vì vậy, PVC is often used as a substrate in drug packaging, and the overall barrier properties are enhanced by compounding with other high barrier materials (such as aluminum foil). Vì vậy, PVC can be widely used in the packaging of pharmaceutical products.

Application types of pharmaceutical PVC (polyvinyl clorua) in medicine packaging:

Bao bì vỉ

PVC/PVDC composite structure is often used in blister packaging, especially for solid drugs such as tablets and capsules. This packaging can provide effective separation protection to prevent drugs from being affected by air and moisture. Blister packaging can be thermoformed or cold stamped. PVC is usually used in the thermoforming process with a heating temperature of about 100℃ to 150℃.

pharmaceutical blister packaging

Portion-dose packaging

PVC/PVDC materials are easy to cut and can be flexibly designed into independent packaging of one dose and one blister, which is convenient for patients to take when using and reduce drug waste.

Special pharmaceutical packaging:

For pharmaceuticals that are sensitive to moisture, ôxy, vân vân., such as antibiotics, vitamins, special capsules, vân vân., PVC/PVDC materials can provide excellent protection.

Infusion bags

PVC is also used to make medical infusion bags. Studies have shown that adding organotin can improve the transparency and processing fluidity of medical PVC infusion bags.

Plastic components for pharmaceutical packaging

According to material classification, PVC is one of the commonly used materials for plastic containers and components for pharmaceutical packaging, and can be used to make plastic components such as covers and interfaces.

The above are some of the main application types of pharmaceutical PVC in pharmaceutical packaging, which utilize the characteristics of PVC materials, such as barrier properties, mechanical strength and processing properties, to ensure the quality and safety of drugs.
