Key Properties of Packaging-Grade Rigid PVC

Clarity and Visual Appeal

Rigid PVC sheet stands out for its glass-clear transparency, with light transmittance exceeding 90%. This clarity is non-negotiable for pharmaceutical blister packs, where pharmacists and patients must visually inspect tablets without opening the package. For luxury folding boxes, high-gloss PVC creates a premium shelf presence that elevates brand perception.

• Over 90% light transmittance for crystal-clear product visibility.

• High-gloss surface finish enhances print vibrancy and retail display.

• Matte and frosted options available for sophisticated cosmetic packaging.

These visual properties make rigid PVC the preferred material for brands that rely on at-a-glance product inspection and premium unboxing experiences.

Barrier and Chemical Resistance

Rigid PVC provides reliable protection against moisture, oils, and many chemicals—critical for maintaining drug efficacy and product integrity. Standard PVC offers good baseline barrier performance, while PVDC-coated variants deliver exceptional moisture and oxygen resistance for highly sensitive formulations.

• Good moisture barrier suitable for most solid-dose medications.
