Softgel blister projects should start with the actual product dimensions, the required blister material system, cavity depth, feeding suitability, output requirement, and downstream packaging plan. Those variables determine whether a given blister-machine configuration fits the application.
This guide works through them in that order. If you're at the earlier question of plate versus roller machines and blister materials in general, that's the blister packaging machine buying guide; this piece assumes softgels are the product and stays with the configuration decisions that follow from it.
Forming depth and cavity fit
Forming depth is one of the first specifications to check for a softgel application, because the cavity must accommodate the actual product geometry.
The published specifications differ across the two blister packaging machines in our range. The automatic blister packing machine specifies a forming area of 250 × 180 mm and a forming depth of 26 mm in alu-plastic and 14 mm in Alu-Alu. The high-speed roller machine specifies a maximum forming area up to 320 × 250 mm and a maximum forming depth of 12–26 mm, customizable.
On the plate machine, the published maximum forming depth differs between alu-plastic and Alu-Alu configurations, so cavity fit must be checked against the material system selected. That check should happen early, because it can rule a configuration in or out before any other specification matters.
Use actual product dimensions and, where practical, physical samples during configuration.
Material system
The two machines document their materials differently, and the terminology is worth keeping precise.
The plate machine specifies forming film as PVC, PVDC, or PET, and lidding material as aluminum foil (PTP). The roller machine lists material compatibility as PVC, PVDC, and aluminum foil, without separating forming and lidding in its published specification — so confirm the intended forming/lidding combination for that machine during scoping. The blister packaging machines collection describes blister cards produced using PVC, Alu-PVC, or Alu-Alu material systems.
On material choice, the product documentation is appropriately careful: material choice depends on the barrier protection your product requires. We'll leave it there rather than making comparative barrier-performance claims, because those depend on your formulation, your market's requirements, and stability data — questions for your packaging supplier and your stability program, not for a machine vendor alone.
From the equipment side: the machine has to be configured for the material system you choose, and that choice interacts with available forming depth as noted above. So the sequence is: determine your barrier requirement first, then confirm cavity fit within that material system's forming envelope.
Feeding and product handling
The plate machine uses an automatic vibratory/channel feeder to load product into cavities. The roller machine uses servo motor feeding, described as accurate and stable, with automatic material detection to reduce waste.
Feeding suitability should be confirmed against the actual product and samples during scoping. Tooling and feeding are matched to product size and shape, so feeding configuration is part of the scoping conversation rather than a standard setting — confirm it with samples rather than inferring it from an applications list.
Output and machine class
The two machines represent different production positions.
The plate-type automatic machine is described as built for small-to-mid batch supplement and pharmaceutical production, balancing automation with flexibility; its packaging speed is confirmed per configuration rather than published as a single figure.
The roller-plate high-speed machine is specified at 2,000–8,000 blisters per hour, with a continuous roller sealing system, PLC touchscreen control, servo feeding, and a quick mold change design.
Which class fits depends on your blister volume, and blisters per hour is a different unit from bottles per hour or capsules per hour — convert your finished-goods requirement into blisters per hour (packs per month ÷ production hours at rate) before comparing. Nominal blisters-per-minute figures are model-rated; actual output depends on product size, blister format, tooling, film and foil, machine configuration, setup, and operator workflow.
For current pricing, lead times, and commercial terms, see the individual product pages or request a quote — those vary by configuration and are confirmed per order.
Changeover and SKU count
If you run one softgel in one format, changeover has limited impact. If you run several, it becomes a meaningful operational cost.
The roller machine's documentation states a quick mold change design, with mold change typically within 30–60 minutes depending on operator experience. Tooling is product- and format-specific, so every additional softgel size or blister layout is a tooling item and a changeover event. Count your SKUs during specification rather than specifying against a single product.
Stainless and tooled contact parts on these machines support cleaning and format changeovers between products.
Utilities and facility fit
Compressed air is required on both: 0.4–0.6 MPa on the plate machine, 0.6–0.8 MPa on the roller machine, with the air compressor not included on the roller machine. Power on the roller machine is specified as 380V three-phase, customizable to 220V; on the plate machine, power is confirmed per configuration.
Footprint deserves attention. The plate machine is specified at 3,900 × 730 × 1,600 mm and 1,600 kg; the roller machine at approximately 1,500–2,500 kg. The plate machine is nearly four metres long, so the room has to accommodate the equipment footprint plus practical operator and service access.
Downstream packaging
Blister packing generally follows counting or inspection, and can feed downstream cartoning. Both machines are documented as pairing with cartoning, and the roller machine can also integrate with counting, inspection, and batch coding equipment.
Plan this at specification time. A blister machine that outruns your cartoning capacity produces work-in-progress rather than finished goods — the same pace-matching logic that governs bottling lines applies here.
A specification checklist for softgel blistering
- Actual softgel dimensions — with samples where practical
- Barrier requirement, determined with your formulation and stability data
- Cavity fit within that material system's forming depth envelope
- Blisters per hour required, converted from finished-goods volume
- Number of softgel sizes and blister layouts, and expected changeover frequency
- Facility: floor run length, power supply, compressed air availability
- Downstream cartoning capacity and coding requirements
- Documentation requirements for your quality system
