Truepack Machinery, a specialist blister‑machine manufacturer in Ahmedabad, supplies several ALU blister variants including single‑track ALU lines, ALU‑ALU packers, and automatic double‑track models for higher outputs. These machines form cavities either by cold‑forming aluminium base foil (for ALU‑ALU) or by thermoforming PVC/PVDC film (for PVC‑ALU), then fill cavities with tablets or capsules and seal them using aluminium or laminated CR foil under controlled heat and pressure to achieve hermetic packs.
Typical Truepack ALU blister machines have capacities around 25–30 packs/min and maximum stroke rates of about 30 strokes/min, with machine dimensions close to 8 × 4 × 5–6 feet, making them suitable for medium‑scale pharma operations. The structure is built in stainless steel, providing a heavy‑duty yet hygienic frame, and is driven by an electric system on 415 V three‑phase power, with a Human Machine Interface (HMI) used to set speed, sealing temperature, and monitor alarms and counters.
Key features highlighted in marketplace listings include high efficiency, durable construction, heat‑sealing technology, and automatic operation that minimizes manual intervention. Options such as automatic double‑track ALU packaging, quick‑change tooling, and GMP‑compliant design allow users to adapt the machine to various product sizes and regulatory requirements, with typical pricing for Truepack ALU blister machines from about INR 7–12.5 lakh per unit depending on model and configuration.
