Transparent Color PVC Roll Film Sheet for Pharmaceutical Blister

Transparent color pvc roll film sheet for pharmaceutical blister packaging is a material specially designed to protect drugs from external environmental factors such as humidity, oxygen and light, while providing a clear display of drug information. This transparent color PVC roll film sheet is widely used in blister packaging in the pharmaceutical industry, especially for the packaging of solid drug forms such as tablets, capsules, pills, etc. It not only protects drugs from the external environment, but also provides a convenient single-dose packaging solution.

Material characteristics

– Transparency: PVC (polyvinyl chloride) material has good transparency, and the drugs in the package can be clearly seen, which is convenient for identification and use.

– Color selection: Although PVC itself is transparent, PVC film can be produced in a variety of colors by adding masterbatch or coating process, which not only increases the aesthetics, but also can be used to distinguish different drug types or brands.

– Flexibility and processability: PVC film is soft and easy to form, and can be made into a blister structure through the blister process to meet the packaging needs of drugs of different shapes.

– Chemical stability: It is inert to most drug ingredients, not easy to chemically react, and ensures the stability of drugs.

– Barrier performance: The barrier capacity for water vapor and oxygen is limited (water vapor permeability is about 2.5g/(m²·day), oxygen permeability is about 30cc/(m²·day)), and it is necessary to combine aluminum foil and other materials to improve the protection effect, which can effectively extend the shelf life of drugs.

– Mechanical strength: It has good tensile strength and impact resistance, is not easy to break, and ensures safety during transportation and storage.

– Easy to form: PVC material is suitable for thermoforming process, and can be deformed by heating to meet the needs of blisters of various shapes.

Performance requirements of transparent color pvc roll film sheet for pharmaceutical blister:

– Compliance with medicine packaging material standards: It needs to pass the national drug packaging material standard certification to ensure non-toxic and pollution-free, and is suitable for direct contact packaging of drugs.

– Physical properties:

Thickness and strength: The common thickness is 0.25mm, and it needs to have tensile and tear resistance to avoid packaging damage.

Thermoformability: It is easy to soften and form under heating conditions, and the blister shape remains stable after cooling.

Printing adaptability: It supports ink adhesion, ensures that the text and pattern are clear and wear-resistant, and meets environmental protection requirements.

Applications of transparent color pvc roll film sheet for pharmaceutical blister:

– Single-layer PVC blister: Suitable for common medicines with low barrier requirements, such as tablets, capsules, etc.

– Composite structure blister:

PVC/PVDC composite: PVDC (polyvinylidene chloride) coating significantly improves barrier properties and extends the shelf life of medicines.

PVC/aluminum foil composite: The aluminum foil layer provides complete barrier, suitable for medicines sensitive to oxygen and moisture.

– Customized requirements: Supports customization of thickness, color, and size to meet the requirements of different drug specifications and brand design.
