Thermoform Alu-PVC / PVDC Blister Packers & Automatic Foil Strip Machines
High-speed transparent PVC/PVDC/Aclar thermoform blister machines (60–250 BPM) and SLB-160 double-foil strip packers for friable and effervescent tablets.
Compact Transparent Blisters vs Zero-Draw Double-Foil Strips
When APIs remain stable under moderate moisture barriers—or upgrading 0.25 mm PVC (WVTR 4–6 g/m²/day) to PVC/PVDC 40–120 gsm (WVTR 0.3–0.8 g/m²/day) meets ICH Zone II/IVa shelf life—thermoformed Alu-PVC/PVDC blisters cut card size by 35% and run 50–100% faster than cold-form Alu-Alu. Conversely, for large 20–28 mm effervescent or orally disintegrating tablets that crack in push-through cavities, SLB-160 double-foil strip packers inside blister and strip packing machines seal pills gently between two 0.08–0.10 mm composite foil webs.
Both systems integrate online batch printing, perforation slitting, and carton conveyor discharge.
Thermoform Alu-PVC vs SLB-160 Strip Packer Specs
Side-by-side comparison of forming physics, materials, and speed:
| Specification | DPP-150 / 260 Thermoform Blister | SLB-160 Double-Foil Strip Packer |
|---|---|---|
| Forming Physics | 90–130 °C contact/radiant heat + positive air | Heated rotary cavity sealing rollers (zero draw) |
| Base & Lidding Webs | 0.20–0.40 mm PVC/PVDC/PET + 0.02 mm PTP | 2 × 160 mm Alu-PE / paper-Alu-PE (0.08–0.10 mm) |
| Reel Core Diameter | 70–76 mm standard pharma core | 70–75 mm universal global reel core |
| Output Envelope | 60–180 blisters/min (rotary up to 250+) | 60–140 strips/min (4–8 lanes across 160 mm) |
| Patient Opening Mode | Thumb push-through PTP foil | Easy-tear V-notch peelable/tear foil pocket |

cGMP Cleanroom & Validation Notes
- Positive-Pressure Air Blowing Gives Uniform Wall Thickness: Filtered
0.5–0.7 MPacompressed air blows softened PVC uniformly into female mold corners without mechanical plug marks on crystal-clear blisters. - Child-Resistant (CR) Peel-Push Lidding Option: Run paper/PET/Alu laminate lidding with kiss-cut peel tabs to meet US CPSC F=1 child-resistant senior-friendly packaging standards.
- Brushless Vertical Drop on Strip Packers: Vertical rotary sealing rolls let uncoated chewable or effervescent tablets drop straight into sealing pockets by gravity with minimal powder dusting.
