This machine can be specified using the following characteristics:

You should look at its frame construction: The machine must be strong and stable when it is set to run.

This equipment should be heavy because its weight facilitates its smooth operation.

It should be made from the recommended materials: For instance, it should be made from stainless steel since this guarantees its strength to weight ratio.

At the same time, there is no flacking risk and corrosion.

The device should be tied together in bolts or it can be welded: This helps in reducing contamination of the products.

When it is welded, it does not require frequent tightening of bolts since they will not loosen up over time.

It should have a film tracker: The machine should keep the web of films at the center and ensure there is consistent tension.

When there is a fault, the sensor detects the bag edge.

This triggers the automatic shifting of the whole film to the center of the machine and the packaging process continues.

This equipment should produce less noise during operation: A lot of noise from the machine indicates that has some problems.

When it is too noisy, it’s either from vibration or due to friction.

This means that you have to do more of part replacement since there will be wear and tear.

It’s recommended that before you source this type of machine, request the supplier to run the machine in your presence.

This will help you in detecting if you are buying a good device.

The machine should have ease of changeover: This is very critical because it helps in facilitating the machine adjustments made for different packaging sizes and product types.

This must happen within the shortest time possible to ascertain whether this machine is good in this area or not.

It should also be tool-free and should take at least 30 to 45 minutes or less.

It should possess controls: The controls ensure the efficient operation of the machine and the achievement of the desired results.

In this case, this machine should have started, stopping, and other machine functions.

It must have a program logic controller and a human-machine interface.

To operate this machine, feed a roll of plastic film into the machine’s long, hollow conical tube.

The web of film is pulled by a film transport belt that is located on the forming tube side.

This is found at the front end of this machine.

The film is then unwound from the roll and taken through the weighted pivot arm situated at the machine rear.

The arm keeps the film under tension as it moves through the rear.

The film also passes through the printing unit where the logo, graphics, and other data are printed using ink-jet.

Once this is done, the film goes through the registration of a photo eye that detects the registration marks.

This photo eye controls the movement of the film and positions it correctly in readiness for cutting.

This film then moves through a film tracking sensor where its position is detected through the machine.

Any deviation from the normal position by the film triggers the sending of a signal for automatic correction.

The outer edge is sealed to form a bag through the horizontal sealing bar clamps at the bottom.

Once the bag is formed, it’s lowered into the weighing table so that the products can be filled into it.

The machine then fills the bag to the recommended weight and when it’s done, it stops.

The next bag is ushered in for a filling.

The bags that have already been filled are sealed at the top using a horizontal sealing bar.

They are then taken to the next level of the packaging line to continue for further packaging into cartons.
