Stop risking drug stability and patient safety to blister seal failures, crystal points, or regulatory audit rejections. At HSQY, we engineer pharmaceutical-grade rigid PVC films specifically for the stringent demands of the healthcare packaging industry. Extruded in strictly controlled ISO-classified cleanroom environments, our films guarantee zero contamination, exceptional optical clarity for visual inspection, and flawless thermoforming performance for unit-dose blister packs.
Backed by advanced melt-filtration systems and precision gauge control within our vertically integrated facilities, we ensure that every roll maintains the exact thickness uniformity required to prevent barrier weak spots after deep-draw forming. From standard 250-micron clear PVC for general solid oral dosages to high-barrier PVDC-coated alternatives, HSQY provides the compliant, reliable material architecture your packaging lines demand.
Cleanroom Extrusion & Zero Crystal Points: Manufactured in dust-free workshops with multi-stage melt filtration, eliminating black spots and impurities that cause micro-leaks or compromise the aesthetic integrity of medical packaging.
Perfect PTP Foil Synergy: Our PVC surface chemistry and flatness are precisely calibrated to ensure a hermetic, tamper-evident heat-seal bond with standard PTP aluminum lidding foils, eliminating "false seals" and delamination during transit.
Gauge Uniformity for Deep Draws: Advanced online thickness gauging ensures uniform micron distribution. This prevents the blister cavity corners from thinning out excessively during thermoforming, maintaining the critical moisture barrier where the drug is most vulnerable.
Global Regulatory Compliance: Fully compliant with FDA, EU 10/2011, and ISO 15378 standards for primary pharmaceutical packaging. We provide comprehensive TDS, COA, and heavy-metal/extractable testing reports to support your DMF (Drug Master File) submissions.
Different drug formulations require specific barrier and optical properties. Explore our specialized pharma PVC matrix:
Standard Pharma-Grade Clear PVC (0.20mm - 0.40mm): The industry workhorse for standard tablets, capsules, and lozenges. Offers excellent rigidity, high gloss, and optimal cost-efficiency for high-speed blister packaging lines.
PVDC-Coated High-Barrier PVC: Engineered for highly hygroscopic (moisture-sensitive) drugs and effervescent tablets. The polyvinylidene chloride coating drastically enhances the moisture and oxygen barrier while retaining the thermoformability of a PVC base.
UV-Blocking Tinted PVC (Amber/Opacified): Custom-colored formulations designed to protect light-sensitive pharmaceuticals, APIs, and photosensitive medical diagnostics from UV degradation without sacrificing structural integrity.
*Available in custom slit widths (up to 1220mm) and precise thicknesses (60 to 500 microns). Density: 1.37 g/cm³. Supplied in continuous roll format with protective PE interleaving.
Selecting the wrong pharma film can lead to shelf-life failures and regulatory non-compliance. Our engineers will help you define:
Drug Moisture Sensitivity Profiling: Calculating the required Water Vapor Transmission Rate (WVTR) to determine if standard PVC is sufficient, or if a PVDC-coated structure is mandatory for your specific API.
Draw Ratio & Cavity Geometry: Matching the initial sheet gauge to your mold's depth-to-width ratio, ensuring the formed blister wall retains adequate thickness for barrier protection.
Sealing Temperature Calibration: Aligning the PVC's thermal properties with your blister machine's heat-seal station parameters and your chosen PTP foil's lacquer formulation.
Q1: Why do some PVC blisters experience "false seals" or leakages with PTP aluminum foil?
A: Leakages typically occur due to micro-warping on the PVC sealing flange or chemical incompatibility between the PVC surface and the PTP foil's heat-seal lacquer. HSQY guarantees ultra-flat flange geometry through precision extrusion and calibrated cooling. Furthermore, we optimize the PVC's surface energy to ensure a hermetic, tamper-evident chemical bond with standard PTP foils, ensuring your blister packs pass all rigorous vacuum decay and dye-penetration leak tests.
Q2: Is standard PVC sufficient for highly moisture-sensitive antibiotics or effervescent tablets?
A: Standard rigid PVC provides a moderate moisture barrier suitable for most general solid oral dosages. However, for highly hygroscopic drugs that degrade rapidly upon exposure to humidity, standard PVC is insufficient. For these applications, we strongly recommend our PVDC-coated PVC films. The polyvinylidene chloride layer drastically reduces the Water Vapor Transmission Rate (WVTR) while maintaining the cost-efficiency and formability of a PVC base, extending your drug's shelf life significantly.
Q3: How do you control crystal points and contamination in pharmaceutical-grade films?
A: Crystal points not only ruin the visual inspection of tablets but can also create micro-channels that compromise the moisture barrier. HSQY extrudes all pharma-grade PVC in strictly controlled, ISO-classified cleanroom workshops. We utilize multi-stage high-precision melt filtration systems and enclosed automated winding to guarantee zero dust, black spots, or environmental contamination, ensuring absolute purity for primary pharmaceutical packaging.
Q4: Do you provide the necessary documentation for pharmaceutical regulatory audits?
A: Absolutely. We understand that compliance is non-negotiable in the pharma industry. Along with our products, we provide comprehensive Technical Data Sheets (TDS), Certificates of Analysis (COA), heavy metal and extractable testing reports, and statements of compliance for FDA, EU 10/2011, and ISO 15378 standards. Our documentation is structured to seamlessly support your Drug Master File (DMF) submissions and regulatory audits.
