Selecting a cup sealing machine is less about the machine itself and more about matching it to your product, container and output targets. This guide walks through the key decisions.
1. Know Your Container
Cup diameter, height and material (PP, PET, PS or aluminum) determine the tooling and sealing head. Measure the rim precisely — a 0.5 mm mismatch causes leaks.
2. Match Fill Type to Product
Liquid, paste, granule and viscous products each need a different filler. A dosing system rated for water will under-perform on yogurt or sauce.
3. Size for Throughput, Not Peak
A rotary line at 6,000 cups/hour suits most SMEs; pilot lines start near 1,000. Buy for your steady state, then scale with a second lane.
4. Don’t Skip Validation
Run a sealing-integrity test on your actual film and cup before committing. SealFilling offers free line assessments with validated parameters.
