Packing ketchup in a cup requires a clean, accurate, and leak-proof process using an automatic cup filling and sealing machine. The ketchup’s thick liquid nature makes it ideal for piston or servo-based filling systems.
Step-by-Step: How to Pack Ketchup in a Cup
1. Cup Loading
Empty plastic or paper cups (usually PP or PET) are loaded automatically using a cup denester.
Common cup sizes: 10g to 100g (individual servings or bulk).
2. Ketchup Filling
A servo or pneumatic piston filler precisely doses ketchup into each cup.
Optional: use a jacketed heated hopper if ketchup needs to be warm for better flow.
3. Lid Placement
You can choose:
Pre-cut foil lids (manually or automatically placed).
Roll film that is automatically cut and applied over the cups.
4. Heat Sealing
Heat is applied to seal the lid tightly to the cup (usually with aluminum foil + PE layer).
Ensures leak-proof, tamper-evident, and hygienic packaging.
5. Date Coding (Optional)
Thermal or inkjet printers mark:
Production date
Expiry date
Batch code
6. Discharge
Sealed cups exit via a conveyor and are collected in trays or packaged into cartons.
