    Ⅱ.Mode of  Flexibility

    According to the mode of flexibility, a sachet machine is broadly divided into two basic types.

    • Horizontal Sachet Machines
    • Vertical Sachet Machines

    Horizontal Sachet Machines

    Horizontal Sachet Machines

    Horizontal sachet machines are extensively used to fill and seal products of various volumes and kinds. These machines form the sachets and fill these at the same time. The packaging material or film travels across different stations horizontally.

    The sachets are formed inside the forming tubes in this type of sachet machine while the products are moving on the conveyors. The edges of the sachet are sealed by the horizontally placed sealing jaws.

    Cereal bars, confectionaries, and foodstuff are packed by horizontal sachet machines.

    Vertical Sachet Machines

    Vertical Sachet Machines

    The films or packaging sheet moves vertically in the vertical sachet machines. Sachets are made at the top of forming tubes in these machines.

    Vertical sachet machines usually seal materials with overlaps and transverse seals. Overlap seals and transverse seals are made at the bottom of the sachet and sides respectively.

    The packaging in vertical sachet machines occurs when products go inside the forming tube and rollers move the film to form the channel. The forming station makes a circular sachet from the plane film.

    Sealing bars bind the side edges of the sachet while horizontal jaws glue the top and bottom end of the sachet.

    Ⅲ.Mode of Packaging Style

    The sachet machine is also categorized according to the mode of packaging styles.

    Three Side Seal Sachet Packing Machine

    Three-side seal sachet packing machine that creates three-side sealed sachet. This sealing is achieved by using a forming cube known as sachet former.

    • Sealing

    Sachet machines perform filling and sealing at the same time. Filling in the sachet occurs from the top open part of the sachet.

    working principle of a sachet machine

    Film Unwinding

    part of sachet machine

    In this step, film rollstock is unwound by the rollers, transport belts, and the dancer’s arm. Film usually made up of aluminum or PE is positioned on rollers, which are present at the base of the machine.

    Servo motors and dancer’s arms prevent the film from drifting and keep it under tension.



    This step is optional.  As the film goes through the printer, the date, batch code, logos, etc are printed on the film.

    Sachet Forming

    sachet forming

    The film moves to the sachet forming station after printing. This unit places the edges of the film side by side to create a sachet. Sealing jaws are used to seal the vertical and bottom side of the sachet.


    part of sachet machine 5

    Feeding units or auger fillers are used to fill the sachet with products. The product is dropped in the sachet when it is ready.


    film sealing

    After the product is packed in the sachet, the top edge of the sachet is sealed by sealing jaws. These jaws press the two top edges together, sealing them with heat or ultrasonic sealing.

    Cutting knives are used to cut the sachet by moving inside sealing jaws. Afterward, jaws open up and the sachet is released.

    8.What are the major components of the sachet machine?

    It is essential to know about the components of sachet machines because this aids in solving the issues that arise in these parts during the normal machine operation.

    The sachet machine is divided into four basic areas

    • Filling
    • Sachet Forming
    • Feeding and Printing
    • Sealing

    Various parts function in the above-mentioned areas. These parts are classified into two major categories

    • Hardware
    • Software


    The hardware components of sachet machine are described below:


    These parts fill and load the products into the sachets. These parts have built-in sensors for accurate dosing of the products. First, the bulk products are loaded in the feeding unit, which then packs them into sachets.

    The sachet packing machine contains a hopper to hold packaging ingredients and dispense them toward the bottom when required.


    Film Unwinding Rollers

    part of sachet machine 2

    These rollers unwind the film from the rolling stock. These parts are either unpowered, use friction brakes to unwind the packaging material, or can be powered by motors. These also provide necessary film tension. These parts also have a utility knife for cutting the film.

    Dancer’s Arm

    Dancer’s arms are essential in keeping the film under tension. These dancers' arms move in an upward and downward direction to maintain film tension when the film is being unwound. These parts also aid in maintaining sachet count and keeping the film on track.

    part of sachet machine 3


    Many types of sensors are present in sachet machines such as:

    • A diffuse sensor is used to identify the end portion of the film.
    • An inductive sensor is used for detecting errors in the movement of the dancer’s arm.
    • Registration sensor aids in checking registration marks which help in the synchronization of cutting and sealing processes.
    • Optical sensors are crucial in detecting the edge for trim.

    Registration Section

    In this section, registration sensors are employed for detecting the registration mark which aids in the final placement of the end seal of the sachet and the cutting of the sachet. It also provides a tracking mechanism that prevents the film from drifting informing section.

    Forming Tube

    The forming tube is a cone-shaped structure in which the flat plane packaging materials is altered to form circular or tubular-shaped package. The size and design of forming tube depend upon the type of product and packaging film.

    Pull Belts

    part of sachet machine 7

    These pull belts aid in providing force for pulling the film through the sachet machine. These are the vacuum belts that offer better gripping.

    Sealing Jaws

    There are two kinds of sealing jaws:

    Horizontal or Cross Sealing Jaw

    These jaws seal the top side of the filled sachet and perform the bottom sealing of the next one. It also cuts and separates the sachet from each other.

    Vertical Sealing Jaw

    These are square or box jaws that move in the upward and downward direction to seal the sides of the packaging film.


    The parts that comprised of software are:

    Servo drives

    part of sachet machine 4

    Servo motors are employed for the purpose of controlling fill cycle. These control the main injector and speed of the sachet forming process.

    PID control

    PID control assists in providing precise control of film unwinding by regulating various devices like motors, gears, and brakes. It also regulates the temperature of various components.


    Variable frequency device or VFD is used for controlling the speed and torque of power supply of sachet machine.

    9.What is the sealing system of a sachet machine?

    The sealing system of sachet machines is described below:

    Heat Seal

    part of sachet machine 5

    It is the classical way of sealing the sachet. It joins two layers of the film by using heat. In a heat seal, heat is applied to polymer layers by the means of a heated die or sealing rod.

    It is robust and inexpensive but carried out in many steps to ensure the quality of sealing thus increasing machine space print.

    10.Can a sachet pack machine deal with different products, sachet sizes, and styles?

    Firstly! whatever the status of your product whether granules, powders, liquid, or viscous content. A sachet packing machine is an ideal packaging solution for it. But you must know the type of filler you require to integrate with the machine.
