High Barrier PVC/PCTFE Film For Blister Packaging

High barrier PVC/PCTFE film is a composite material specially used for blister packaging. It combines the excellent properties of polyvinyl chloride (PVC) and polytetrafluoroethylene (PCTFE). It has excellent barrier properties, excellent mechanical strength and excellent transparency. It is an ideal packaging material for industries such as food, pharmaceuticals and consumer goods.

In the field of pharmaceutical packaging, blister packaging needs to ensure the stability of drugs during the shelf life, especially solid pharmaceutical preparations that are sensitive to humidity. Although traditional aluminum-plastic packaging has good barrier properties, it has disadvantages such as poor transparency and inability to visually check the status of drugs. Ordinary plastic packaging is difficult to provide sufficient protection in high humidity environments. Today, PVC/PCTFE film has been recognized by the global pharmaceutical regulatory system and complies with FDA, EU, USP and EP standards, becoming one of the preferred materials for pharmaceutical-grade blister packaging. With the development of the pharmaceutical market in hot and humid climate regions such as Brazil and India, this material has successfully replaced traditional aluminum shell packaging with its excellent moisture-proof properties, demonstrating a wide range of environmental adaptability.

Technical parameters of high barrier PVC/PCTFE film:

– Material composition: composite material of PVC and PCTFE

– PVC (polyvinyl chloride): a general-purpose thermoplastic with good molding and processing performance, mechanical properties and chemical stability, relatively low price, and widely used in the packaging field. However, its barrier properties are limited, especially the barrier effect against moisture and oxygen needs to be improved. The thickness is usually between 200-300μm.

– PCTFE (polychlorotrifluoroethylene): a fluorine-containing polymer with excellent barrier properties, especially strong barrier effect against water vapor and oxygen, which can effectively prevent external moisture, oxygen, etc. from entering the packaging and protect the packaged items. At the same time, PCTFE also has good chemical stability, weather resistance and transparency. The thickness ranges from 10-100μm.

– Barrier performance: oxygen permeability and water vapor permeability meet industry standards.

– Transparency: ≥90%

Performance characteristics of high barrier PVC/PCTFE film:

– High barrier property:

PVC/PCTFE film combines the processing properties of PVC and the barrier properties of PCTFE, and has excellent barrier effect on water vapor, oxygen, etc., which can effectively extend the shelf life of packaged items and prevent medicines, foods, etc. from being damp, oxidized and deteriorated.

– Good thermoforming property:

It can be thermoformed on traditional blister packaging equipment, and can be easily made into blisters of various shapes to meet the packaging needs of different products.

– Chemical stability:

It has good chemical stability and can resist the erosion of various chemical substances. It is suitable for packaging some corrosive or chemically sensitive items.

– High transparency:

The film has high transparency and can clearly display the items in the package, which is convenient for consumers to check the appearance and quality of the product and enhance the display effect of the product.

– Good mechanical properties:

It has certain strength and toughness, can withstand certain external forces during packaging, transportation and storage, is not easy to break or damage, and protects the safety of the items in the package.

Application areas of high barrier PVC/PCTFE film:

– Pharmaceutical packaging:

Used to package tablets, capsules, pills and other medicines. It can effectively protect medicines from moisture, oxygen and light, ensure the quality and stability of medicines within the validity period, and is one of the commonly used materials for pharmaceutical blister packaging.

– Food packaging:

Can be used to package some foods that have high requirements for moisture and oxidation resistance, such as chocolate, nuts, biscuits, etc., to extend the shelf life of food and maintain the taste and flavor of food.

– Electronic component packaging:

Can provide good protection for electronic components, prevent them from moisture and oxidation during storage and transportation, avoid short circuits and corrosion caused by moisture and oxygen, and ensure the performance and quality of electronic components.

High barrier PVC/PCTFE film is a high-quality choice in modern blister packaging. With its excellent barrier properties and good mechanical properties, it meets the needs of various industries for high-quality packaging materials. Its core value lies in its unparalleled moisture resistance, combined with excellent molding properties and transparency, which solves the global problem of drug stability in hot and humid environments.
