Film PVC rigide transparent pour l'emballage pharmaceutique

Film PVC rigide clair (film de chlorure de polyvinyle) est un matériau largement utilisé pour l'emballage pharmaceutique. Ses excellentes propriétés physiques et sa conformité réglementaire stricte lui ont valu une position importante dans l'industrie pharmaceutique. Le film PVC est le matériau grand public de l'emballage de blister pharmaceutique, Comptabilité de plus 60% du marché.

Paramètres centraux du film PVC rigide clair:

– Épaisseur et spécifications:

Common thicknesses range from 0.20-0.45mm, and widths range from 75-1300mm. Customizable options include transparent, translucent, or tinted (par exemple., bleu, amber).

– Physical Properties:

High transparency and gloss: Ensures visual inspection of pharmaceuticals and facilitates identification of changes in their appearance.

Résistance mécanique: Biaxial stretching (par exemple., a stretch ratio of 3.2-3.5x in the longitudinal direction and 3-5x in the transverse direction) significantly improves tensile strength (≥44MPa) and impact resistance, meeting the molding requirements of blister packaging.

– Stabilité chimique:

Resistant to pharmaceutical corrosion, it is suitable for a variety of dosage forms, including tablets, capsules, and injection trays. Optimized Composite Structure: When laminated with materials such as PVDC and PE, propriétés de barrière (moisture and oxygen resistance) are significantly enhanced, extending the shelf life of pharmaceuticals.

Key features and advantages of transparent rigid PVC film inclure:

1. Excellent Physical Properties

– High Transparency:

PVC film boasts a light transmittance exceeding 85%, clearly displaying the appearance of pharmaceuticals and facilitating consumer identification.

– High Mechanical Strength:

Excellent tensile strength and toughness make it resistant to breakage, effectively protecting pharmaceuticals from impact during transportation and storage.

– Good Barrier Properties:

Basic PVC rigid sheet offers average water vapor barrier properties, but when laminated with PVDC or aluminum foil, the water vapor transmission rate can be reduced to <0.5g/m²/24h, meeting pharmaceutical moisture-proofing requirements.

2. Strong Processing Flexibility

– Excellent Thermoformability:

Hot pressing allows precise adaptation to tablet/capsule dimensions, reducing friction during movement.

– Proven Lamination Process:

When laminated with materials such as aluminum foil and PVDC, Film PVC rigide can create high-barrier, light-shielding blister packaging (PTP), suitable for photosensitive and hygroscopic drugs. Excellent Printing Performance: The smooth surface supports clear printing of drug information and anti-counterfeiting labels.

3. Highly Cost-Effective

– Low Raw Material Cost:

Compared to materials like PET and PVDC, PVC film is more affordable, making it suitable for large-scale production.

– Mature Processing:

Mature processing technologies such as extrusion and calendering offer high production efficiency, further reducing costs.

Typical Applications of Clear Rigid PVC Film:

– emballage blister:

Direct contact with the drug provides a physical barrier to prevent contamination and deterioration.

– Printing and Labeling:

The smooth surface supports offset printing, meeting drug information labeling requirements.

– Special Applications:

Par exemple, PVC/PVDC/PE composite film is used for high-humidity or easily oxidized drugs (such as antibiotics) to ensure stability.

In the pharmaceutical packaging industry, clair Film PVC rigide is commonly used in trays, plaquettes thermoformées, and other packaging formats, effectively protecting drug quality and safety.
