صفائح PVC شفافة صلبة في لفة لتغليف فقاعات الأدوية

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. أول, 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:

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

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

الطول: Usually determined according to order requirements.
