Rigid PVC Clear Sheet in Roll for Pharma Blister Packaging

Rigid PVC clear sheet in rolls for pharmaceutical blister packaging are a common material used in pharmaceutical packaging. These rolls are made primarily from high-grade sanitary-grade polyvinyl chloride resin, with the addition of imported high-grade auxiliary materials, and are produced in a cleanroom. Rigid PVC clear sheet films are mainly used for blister packaging of various pharmaceuticals, such as tablets and capsules. Their transparency can reach over 73%, with a smooth and flat surface, effectively showcasing the appearance of the medicine and enhancing consumer trust.

Processing technology of rigid PVC clear sheet in rolls:

Generally produced using extrusion or calendering processes. First, the PVC resin and additives are mixed evenly, then processed into rolls of a certain thickness and width using an extruder or calender. The rolls then undergo cooling, traction, and winding processes to create the finished product.

Specifications of rigid PVC clear sheet in rolls:

Thickness: Common thicknesses are 0.05mm-0.07mm, with 0.06mm being the most common. Other thicknesses, such as 0.20mm-0.45mm, are also available.

Width: Generally 420mm-1500mm, custom widths are available upon request.

Length: Usually determined according to order requirements.

Performance characteristics of rigid PVC film sheets:

– Good barrier properties:

Excellent barrier properties against oxygen and water vapor, effectively preventing medications from becoming damp and oxidized, extending their shelf life.

– High transparency:

Crystal-clear, clearly displaying the appearance of medications, facilitating consumer identification and contributing to aesthetically pleasing packaging.

– Easy to form and heat-seal:

Excellent thermoforming properties; can be quickly formed into blister shapes under certain temperature and pressure conditions; exhibits good heat-sealing properties with pharmaceutical aluminum foil and other materials, forming reliable sealed packaging.

– High safety:

Low vinyl chloride monomer content and low oxidizability index, meeting relevant hygiene standards; safe and non-toxic, suitable for direct contact with medications.

– Good mechanical properties:

High hardness, tensile strength, and impact resistance, effectively protecting medications during transportation and storage. Particularly suitable for individual packaging of solid dosage forms such as tablets and capsules.

– Chemical stability:

Resistant to acids and alkalis, corrosion-resistant; can be in long-term contact with medications without chemical reaction, ensuring stable efficacy.
