Tray, Cup & Bowl Sealing

Equipment that takes a pre-made rigid container including a tray, cup, or bowl and seals the container using paper, plastic lid stock, foil, or other material, such as sealing of cups of ramen.

Category Explained

Tray, Cup & Bowl Sealing machines are designed to apply secure seals over pre-formed containers to protect the contents and extend shelf life. These machines handle various container materials and shapes—whether round cups, compartmentalized trays, or single-serve bowls—and apply a lid or film using heat, pressure, or a combination of both. Sealing materials may include foil for tamper resistance, peelable films for consumer convenience, or paper-based lids for eco-conscious applications. The process is widely used in food manufacturing, particularly for ready-to-eat meals, dairy products, snacks, and shelf-stable or refrigerated goods. These machines are valued for their precision, hygiene, and compatibility with high-volume production environments.

Typical products and applications include:

  • Yogurt, sour cream, and fruit cups: Sealed with foil or film to maintain freshness and prevent contamination
  • Instant ramen, noodle bowls, or soups: Sealed with foil or plastic film to enable shelf stability and reheating
  • Refrigerated or frozen prepared meals: Tray-sealed to contain heat and prevent leaks during transport
  • Deli sides, dips, and sauces: Portion-packed and sealed in small cups for foodservice or retail
  • Ready-to-heat pastas or casseroles: Compartment trays sealed to preserve flavor separation and microwave readiness

Additional Considerations:

  • Offers flexibility in sealing materials and methods: Heat sealing, peelable lids, or ultrasonic options available
  • Can integrate with filling, coding, and labeling systems: Enables full automation within a packaging line
  • Compatible with MAP (Modified Atmosphere Packaging): Helps extend shelf life for perishable products
  • Supports a variety of packaging formats and container sizes: Ideal for both single-serve and multi-compartment applications
  • Ensures tamper evidence and product integrity: Essential for consumer safety and regulatory compliance
