How Does a Thermoforming Packaging Machine Work? Discover the CEHUMA CM Series!

In today's highly competitive food, medical, and industrial sectors, packaging is no longer just about protecting products. Businesses need packaging solutions that extend shelf life, maintain product quality, improve presentation, and meet strict hygiene standards. This is where thermoforming packaging technology has become one of the most trusted packaging methods worldwide.

The CEHUMA CM Series Thermoforming Packaging Machine is designed to provide efficient vacuum packaging and Modified Atmosphere Packaging (MAP) solutions for a wide range of products. Whether you are packaging fresh meat, poultry, seafood, dairy products, bakery items, fruits, dates, ready meals, or medical products, the CM Series offers a reliable and automated packaging solution that helps improve productivity and product protection.

What Is a Thermoforming Packaging Machine?

A thermoforming packaging machine is an advanced automated packaging system that forms packaging trays directly from a roll of plastic film, fills them with products, seals them with a top film, and cuts them into finished packages.

Unlike traditional pre-made tray packaging systems, thermoforming technology creates the package inside the machine itself. This reduces packaging material waste, lowers operational costs, and provides greater flexibility in package design and size.

The CEHUMA CM Series is available for both flexible and rigid film applications and supports vacuum packaging as well as Modified Atmosphere Packaging (MAP), making it suitable for various industries and packaging requirements.

Step-by-Step Thermoforming Packaging Process

  1. Film Unwinding
    The process begins with the unwinding of the bottom film from a roll. Depending on the product requirements, the machine can use either flexible or rigid packaging films.

    The film is continuously fed into the machine with precision, ensuring smooth and consistent packaging operations.

  2. Thermoforming Stage
    Once the film enters the forming station, it is heated to a controlled temperature. The heated film then passes through a forming mold where vacuum and pressure create custom-shaped cavities.

    These cavities serve as packaging trays specifically designed to hold the product securely.

    The thermoforming process allows manufacturers to create packaging in different sizes, depths, and configurations according to product requirements.

  3. Product Loading
    After the cavities are formed, products are loaded into the packages.

    Depending on production requirements, loading can be performed manually or through fully automated loading systems.

    The CEHUMA CM Series can package a wide variety of products, including:

    • Fresh meat
    • Poultry products
    • Seafood
    • Cheese and dairy products
    • Bakery items
    • Fruits and vegetables
    • Dates and dried fruits
    • Ready-to-eat meals
    • Medical devices

    This flexibility makes thermoforming technology one of the most versatile packaging solutions available today.

  4. Vacuum or MAP Sealing
    Once the products are loaded, the top film is applied over the filled cavities.

    At this stage, businesses can choose between two packaging methods:

    Vacuum Packaging

    Vacuum packaging removes nearly all oxygen from the package before sealing. This process helps:

    • Reduce bacterial growth
    • Minimize oxidation
    • Extend product shelf life
    • Preserve product freshness

    Vacuum packaging is widely used for meat, seafood, cheese, and processed food products.

    Modified Atmosphere Packaging (MAP)

    MAP packaging replaces the oxygen inside the package with a carefully controlled gas mixture, typically nitrogen and carbon dioxide.

    This method helps:

    • Maintain product appearance
    • Preserve texture and flavor
    • Extend shelf life
    • Reduce food waste

    MAP technology is particularly popular for fresh meat, poultry, bakery products, ready meals, and fresh produce.

  5. Sealing Process
    After vacuum or MAP operations are completed, the machine creates a strong airtight seal between the bottom and top films.

    A high-quality seal is critical for maintaining product freshness, preventing contamination, and ensuring package integrity throughout storage and transportation.

    The CEHUMA CM Series is designed to deliver consistent sealing quality even during high-speed production operations.

  6. Cutting and Separation
    After sealing, the packaging enters the cutting station.

    The machine cuts the packages into individual units according to the required dimensions and layout.

    Depending on customer requirements, the machine can perform:

    • Individual cuts
    • Multi-pack cuts
    • Easy-open perforated cuts
    • Custom packaging formats

    This provides greater flexibility for retail, wholesale, and export packaging applications.

  7. Product Exit and End-of-Line Operations
    The finished packages exit the machine ready for further processing.

    Additional end-of-line solutions may include:

    • Labeling systems
    • Date coding
    • Check weighing
    • Metal detection
    • Carton packing
    • Palletizing

    This creates a complete automated packaging line that improves operational efficiency and reduces manual labor.
