Pharmaceutical Packing Color Rigid PVC Film

Pharmaceutical packing color rigid PVC film is a packaging material that combines the performance of traditional PVC rigid films with color printing technology. It is widely used in aluminum-plastic packaging of solid preparations (such as capsules and tablets).

Specification of colored rigid PVC film for pharmaceutical packaging:

– Material: Polyvinylchlorid (PVC) is used as the base material, and color effects are achieved by adding pigments or dyes while maintaining the physical and chemical properties of PVC.

– Common thickness: 0.2Millimeter, 0.3Millimeter, 0.4Millimeter, 0.5Millimeter. The thickness selection will affect the strength, molding performance and sealing of the blister.

– Width and length: Generally provided in the form of rolls or sheets, the width is usually between 200mm and 1200mm, and the length can be customized according to customer needs.

– Farbe:

Colored rigid PVC films can provide a variety of colors, the most common ones are transparent, Blau, Grün, Rot, Gelb, etc.. The color can be customized according to customer needs.

Performance characteristics of pharmaceutical packing color rigid PVC film:

– Transparency and color performance:

Colored rigid PVC film can achieve rich colors (such as red, Blau, Grün, etc.) through printing or co-extrusion process, which improves the recognition and aesthetics of pharmaceutical packaging.

– Barriereigenschaft:

Good moisture and dustproof performance, protecting drugs from external environment.

– Temperaturwiderstand:

Stable within the common temperature range of drug packaging (such as room temperature to 60℃).

– Mechanische Festigkeit:

High tensile strength and impact resistance, suitable for automated packaging equipment.

Quality standards and technical requirements

Colored PVC rigid films must meet the following requirements:

– Aussehen: No defects such as cracks, perforations, Beulen, Falten, oil stains, etc..

– The number of impurities such as crystal points and black spots is strictly limited (such as no more than 3 crystal points per 100cm²).

– The color layer must be uniform and consistent, without color difference or fading.

Physikalische Eigenschaften:

– Thickness and width: meet the allowable difference of specifications (such as width ±1mm, thickness ±allowable range).

– Zerreißfestigkeit: longitudinal and transverse average values ≥44MPa.

– Heat sealing strength: strength after heat sealing with aluminum foil ≥15mm.

– Water vapor permeability: ≤ specified value (specific values must be based on pharmacopoeia or enterprise standards).

Chemical and microbiological requirements:

– Vinyl chloride monomer content: ≤ 1 part per million.

– Microbiological limits: Total bacteria ≤ 1000/100cm², mold ≤ 100/100cm², Escherichia coli and live mites shall not be detected.

– Dissolution test: Must meet indicators such as clarity and heavy metals (such as n-hexane non-volatile matter ≤ specified value).

Application scenarios

Pharmaceutical packaging field:

Solid preparation aluminum-plastic blister packaging: Colored PVC rigid films are compounded with aluminum foil and used to encapsulate tablets, Kapseln, etc., which are both protective and aesthetic.

Advantages of pharmaceutical packing color rigid PVC film:

– High recognition: Color design helps consumers quickly identify the type of medicine (such as different colors corresponding to different doses or specifications).

– Kosteneffizienz: Compared with other high-performance packaging materials (such as PET/PE composite films), colored PVC rigid films are relatively low in cost and suitable for large-scale production.

– Umweltschutz: Some companies have developed recyclable or biodegradable colored PVC films.
