Automatic Tray Sealing Machine

Food tray sealing machine

Tray sealing and packaging machine

1. Working Principle

The automatic tray sealing machine adopts an integrated mechanical-electrical control system, which realizes fully automatic operation from tray feeding, positioning, film covering, sealing to finished product output. First, the empty trays are automatically conveyed to the positioning station through the conveyor belt, ensuring accurate alignment without deviation. Then, the pre-cut food-grade packaging film is automatically covered on the tray (the film can be selected according to needs: PE, PP, PVC, composite film, etc.). Next, the heating plate heats the edge of the film to the melting point quickly and evenly, and under the action of pressure, the film is tightly bonded to the edge of the tray to form a sealed and airtight package. Finally, the sealed finished products are automatically conveyed to the discharge area, completing the entire tray sealing process. The whole process is controlled by PLC, with adjustable speed and sealing temperature, adapting to different tray sizes and film materials.

2. Application Fields

Our automatic tray sealing machine has a wide range of applications, covering multiple industries that require tray packaging, with strong versatility and adaptability:
  • Food Industry: Suitable for packaging of fresh fruits and vegetables (strawberries, cherries, lettuce, carrots), cooked food (braised pork, cold dishes, pasta), aquatic products (fish, shrimp, shellfish), dairy products (yogurt, cheese, milk pudding), prepared meals, snacks, etc., effectively keeping food fresh, preventing contamination and extending shelf life.
  • Medical & Pharmaceutical Industry: Used for packaging of medical consumables (disposable syringes, cotton swabs, bandages), small medical devices and pharmaceutical accessories, meeting GMP standards, ensuring sterile and dust-free packaging, and avoiding secondary pollution.
  • Cosmetics & Daily Chemical Industry: Applicable to packaging of small cosmetics (lipsticks, eye shadows, skin care samples), daily necessities (cotton pads, facial masks, small toiletries), with beautiful sealing effect, enhancing product grade and anti-counterfeiting performance.
  • Other Industries: It can also be used for packaging of electronic components, hardware accessories, small toys, pet food, etc., protecting products from moisture, dust and damage during storage and transportation.

3. Product Advantages

  • High Automation & Efficiency: Fully automatic operation, no manual intervention in the whole process of tray feeding, sealing and discharging, reducing labor intensity and labor cost. The production capacity can reach 30-120 trays per minute (adjustable according to tray size), which is 5-8 times that of manual operation, greatly improving packaging efficiency.
  • Stable Sealing Quality: Adopt imported heating elements and precision temperature control system, the temperature is uniform and stable, the sealing edge is smooth, firm and airtight, no air leakage, no film breaking, effectively preventing product oxidation, moisture and pollution, and extending the shelf life of products.
  • Strong Versatility: It can adapt to various tray materials (PS, PP, PET, paper trays) and sizes (customizable according to customer needs), and can be matched with different packaging films (transparent film, matte film, vacuum film, barrier film), meeting the diverse packaging needs of different industries.
  • Easy Operation & Maintenance: Equipped with a touch screen operation panel, parameter setting (temperature, speed, pressure) is simple and intuitive, no professional training is required, and ordinary employees can operate it. The machine structure is compact, easy to disassemble and clean, and daily maintenance is simple, reducing maintenance costs.
  • Energy Saving & Environmental Protection: Adopt energy-saving motor and heating system, low power consumption, energy saving and environmental protection. The packaging film used is food-grade, non-toxic, tasteless, in line with international environmental protection standards, and can be recycled, reducing environmental pollution.
  • Certified & Reliable: The machine is CE, ISO9001 certified, made of high-quality 304 stainless steel, corrosion-resistant, high-temperature resistant, durable, and has a service life of more than 10 years. The core components are imported, ensuring stable operation and low failure rate.

    5. Packaging Details

    To ensure that the machine is not damaged during transportation, we adopt professional packaging standards:
    • Inner Packaging: The machine is wrapped with waterproof and shockproof PE film, and the key components (control panel, heating plate, conveyor belt) are wrapped with foam to prevent collision and moisture.
    • Outer Packaging: Use a solid wooden case (plywood) that meets international shipping standards, which is moisture-proof, shock-proof and pressure-resistant, suitable for sea, air and land transportation.
    • Accessories Packaging: All accessories (spare heating elements, tools, maintenance manual, operation manual, certificate) are packed in a separate carton and placed in the wooden case together with the machine to avoid loss.
    • Marking: The outer wooden case is marked with product name, model, weight, volume, fragile, moisture-proof, upward and other signs to remind the transporter to handle it with care.
