Brown PVC rigid sheets are commonly used in pharmaceutical blister packaging due to their excellent light-blocking properties, protecting light-sensitive medications. The following precautions should be observed when using brown PVC rigid sheets for pharmaceutical blister packaging:
Material Quality Control:
Raw Material Safety: The raw materials and additives used in the production of PVC rigid sheets must meet safety requirements to ensure that they do not contaminate the medication.
Appearance and Specifications: The rigid sheets should be free from defects such as scratches, wrinkles, damage, foreign matter, and dirt. Their thickness, width, and other specifications should comply with relevant standards and production requirements.
Production Process Requirements:
Production Environment: From the cooling and shaping stage onwards, the entire production plant for PVC rigid sheets should maintain a cleanliness level of 100,000, preventing microbial and dust contamination.
Molding Process: PVC rigid sheets are commonly formed using calendering or extrusion methods. Temperature, pressure, and other parameters must be strictly controlled during production to ensure uniform thickness and stable performance of the rigid sheets, avoiding defects such as bubbles and flow lines that could affect packaging quality.
Heat Sealing Process: When heat-sealing with PTP aluminum foil, appropriate heat-sealing temperature, pressure, and time should be selected to ensure a tight, flat, and clearly patterned seal without wrinkles or penetration of the mesh pattern. Simultaneously, ensure good compatibility between the heat-sealing material and the brown PVC rigid sheet.
Packaging System Performance Evaluation:
Barrier Properties: In addition to light-blocking properties, the moisture and oxygen barrier properties of the brown PVC rigid sheets should be evaluated to ensure they meet the moisture-proof and anti-oxidation requirements of the packaged medication, preventing deterioration of the medication during storage due to moisture absorption or contact with oxygen.
Seal Integrity: Conduct seal integrity testing according to relevant standards, such as maintaining a vacuum of -80kPa ± 13kPa for 30 seconds. No liquid should penetrate the blister pack, ensuring the seal integrity of the packaging system and preventing medication leakage.
Storage and Transportation:
Storage Conditions: Brown PVC rigid sheets should be stored in a well-ventilated and dry place, away from fire sources and direct sunlight, avoiding moisture and exposure to prevent changes in the properties of the rigid sheets.
Transportation Process: During transportation, care should be taken to protect the packaging to prevent damage, breakage, or deformation of the rigid sheets, which could affect subsequent packaging use.
