Pharmaceuticals need to be protected from moisture to maintain their quality. Brown PVC film is highly resistant to moisture, preventing the ingress of water vapor and ensuring that the drug remains dry and stable. This is especially important for medications that are hygroscopic or prone to degradation in the presence of moisture.

3. Chemical Resistance

The film also offers good chemical resistance, protecting the medication from exposure to chemicals that may be present in the environment or during transportation. This helps to maintain the integrity of the drug and ensures its safety for consumption.

4. Durability and Flexibility

Brown PVC film is durable and flexible, making it easy to form into blister packs. It can withstand the rigors of handling and transportation without cracking or breaking, ensuring that the medication remains protected throughout the supply chain.

5. Customizability

The film can be customized in terms of thickness, size, and shape to meet the specific requirements of different pharmaceutical products. This allows manufacturers to create packaging solutions that are tailored to their needs, enhancing the overall packaging efficiency and effectiveness.

The Blister Packaging Process

Blister packaging is a popular method for packaging pharmaceuticals due to its convenience, safety, and visibility. The process involves forming cavities or pockets in a sheet of material, usually PVC or aluminum foil, and then sealing a backing material over the cavities to enclose the medication. Brown PVC film is commonly used as the blister material due to its properties and advantages as discussed earlier.

The blister packaging process typically involves the following steps:

1. Design and Tooling

The first step is to design the blister pack layout and create the necessary tooling. This includes designing the cavities to hold the medication, determining the size and shape of the blister pack, and creating the molds or dies for forming the blister cavities.

2. Material Selection

Next, the appropriate materials are selected for the blister pack. Brown PVC film is often chosen for its light barrier, moisture resistance, and chemical resistance properties. The backing material, which is usually aluminum foil or paperboard, is also selected based on its compatibility with the medication and the packaging requirements.

3. Forming the Blisters

The brown PVC film is heated and formed into blister cavities using a thermoforming process. The cavities are designed to hold the medication securely and protect it from damage.

4. Filling the Blisters

Once the blisters are formed, the medication is placed into the cavities. This can be done manually or using automated filling machines, depending on the production volume and complexity of the packaging process.

5. Sealing the Blisters

After the medication is filled, the backing material is sealed over the blisters to enclose the medication. This is typically done using heat sealing or adhesive bonding to ensure a tight and secure seal.

6. Inspection and Quality Control

The blister packs are then inspected for quality and integrity. This includes checking for proper sealing, correct filling of the medication, and absence of defects or contaminants. Any defective packs are removed and discarded to ensure that only high-quality products reach the market.

Applications of Brown PVC Film in Pharmaceutical Packaging

Brown PVC film is widely used in the packaging of various types of pharmaceuticals, including tablets, capsules, powders, and liquids. It is suitable for both over-the-counter and prescription medications, as well as for generic and branded drugs.

Some of the common applications of brown PVC film in pharmaceutical packaging include:

1. Packaging of Solid Dosage Forms

Tablets and capsules are the most common solid dosage forms packaged in blister packs. Brown PVC film provides an ideal packaging solution for these products, protecting them from light, moisture, and physical damage.
