Cup filling and sealing machine guide: yogurt, sauce and drink cups

How cup filling and sealing machines work: rotary vs linear, cup denesting, piston filling, foil heat sealing and cutting, plus cup sealer options for yogurt, sauces and tea shops.

Short answer: A cup filling and sealing machine drops empty cups from a denester into moulds, fills them with a piston or pump, places or unwinds a lidding film, heat-seals it to the cup rim and pushes the sealed cups out. Rotary models are compact for small outputs; linear models with several lanes give higher output for yogurt, sauce portions, jelly, juice and coffee concentrate cups.

Stations of an automatic cup filling and sealing machine

  1. Cup denesting — separates cups from a stack into the mould plate.
  2. Cup detection — no cup, no fill.
  3. Filling — piston or pump dosing; agitated hoppers for products with fruit pieces.
  4. Film placing — pre-cut lids or film from a roll.
  5. Heat sealing — heated plate presses the film onto the rim.
  6. Cutting and output — roll-film models cut the lid; cups are pushed onto a conveyor.

Products packed in cups and spoons

Yogurt, pudding, jelly, jam and honey portions, sauce and dip cups, juice and water cups, coffee concentrate, ice cream cones. For single-dose honey or syrup in edible spoons, there is the Honey spoon filling & sealing machine at around 900 pieces per hour.

Manual cup sealer or automatic machine?

Tea shops and cafés sealing a few hundred drinks a day use manual or semi-automatic cup sealers that only seal. Food producers filling thousands of cups need an automatic machine that fills and seals with consistent volume and seal quality.

What to check

  • Cup diameter, height and material (PP, PS, PET)
  • Lidding film type and whether you need printed lids in registration
  • Product viscosity and particles
  • Fill volume and cups per hour
  • Hygiene: cleaning method; UV or other lid treatment if required

Questions and answers

What can a cup filling and sealing machine fill?

Yogurt, sauces, jam, honey, juice, milk, coffee concentrate and similar products, in pre-formed plastic cups.

How fast is a cup filling machine?

Our rotary machine lists 20–30 cups per minute and the linear machine with denester 1,200–1,800 cups per hour.

Can one machine run different cup sizes?

Yes, by changing the mould plate and adjusting the fill volume, within the 5–300 ml range of our models.

Is a cup sealing machine the same as a cup filling machine?

No. A cup sealer only seals filled cups; a cup filling and sealing machine also denests and fills them automatically.
