    6. What Is The Working Principle Of Boba Sealing Machine?


    A boba sealing machine follows a simple working procedure like other sealing machines and offers both heating and sealing functions. The steps involved in the working of a boba sealing machine are

    • Initially the heating element is responsible to heat the plastic lid. This heated plastic lid is placed on the cup when it comes underneath the sealing head.
    • As the heated lid come on the top of cup a particular pressure is applied on it and that creates an air tight seal around the opening.
    • Once the sealing is done, the cutting mechanism gets activated and trims off the excess plastic film. This plastic film is recycled to make other byproducts.
    • As a result of it, neat, clean and secured sealing is performed in an efficient and precise manner.

    7. What Are The Main Components Of A Boba Sealing Machine?


    Boba sealing machine typically has few main components. These are

    • Heating Element

    Heating element or heating head of a boba sealing machine melts the plastic film and creates an airtight seal around the cup. It is usually made of metal and can be controlled to adjust the temperature.

    • Sealing Mechanism

    Specific pressure is applied onto the product through this sealing mechanism. The melted plastic film is pressurized onto the top of cup and sealing of it is carried out. A sealing mechanism is usually of two metal plates that come together to apply the pressure.

    • Cutting Mechanism

    After sealing mechanism, cutting process is performed to remove the excess plastic film that is present around the cup.  A blade or a roller is used to cut the plastic film after heating is performed properly.

    • Film Roll Holder

    The plastic film roll that is used to seal a cup is mounted on this film roll holder. The machine design is done in such a way that is dispenses the film into the sealing mechanism in a completely controlled manner.

    • Cup Tray

    Within the sealing mechanism, the cup in placed in a cup holder for sealing purpose. It is adjusted according to the size and shape of a cup.

    • Control Panel and Power Supply

    The operator gets a direct access to the machine through this control panel. Various aspects like sealing process, temperature, pressure, and sealing time adjustment is done by the operator through this control panel.

    In addition, electrical power supply unit is there to operate the machine and support in smooth production.

    8. What Types Of Boba Sealing Machines Are There?

    According to the working operation of a boba sealing machine, there are two types of boba sealing machine. These types are manual and automatic boba sealing machine. The important feature in both of the machine is

    Polypropylene or polyethylene terephthalate are packaging material used for boba sealing process. These materials are highly durable and light weight and that is why they are well suited for protection of food and beverage material.

    Trays can easily be sealed using plastic material like Polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET). Other than this food and frozen products also use aluminum and paper for their tray packaging.

    • Application

    Boba seals are applied for packaging of beverages like fresh juices, bubble tea and smoothies produced in cafes, beverage shops, stores and also for take away.

    This is a component that is used to cut the sealing film for gaining an appropriate size. The film cutting blade is typically located on the side or back of the boba sealing machine.

    • Electric Pedal

    Some boba sealing machines come with a foot pedal. This allows the operator to activate the sealing process without using their hands. This can be helpful for speeding up the sealing process and improving efficiency.

    • Film Dispenser

    A film dispenser is used to dispense the sealing film from the roll to the sealing machine. This component can be located on the side or back of the boba sealing machine.

    • Film Splicer

    A film splicer is used to join two rolls of sealing film together. This component can be located on the side or back of the boba sealing machine.

    12. Is Boba Sealing Machine Compatible With Different Types Of Sealing Films Or Foams?
