3.What Are The Working Principle Of A Foot Operated Heat Sealer?
A foot operated heat sealer has a simple operation. It follows following steps.
- Initially, the parameters like temperature, heating cycle and speed of foot operated heat sealer are set to standard or according to the material on which sealing is carried out.
- As the parameters are ensured, bags or pouches of different materials are kept on the bottom jaw of a foot operated heat sealer.
- Afterwards the operated pushes down the pedal, both the jaws get in contact and sealing is done due to heat bonding of both jaws.
- As a result of this heating, the material melts and proper sealing is carried out.
- When the cycle is completed, an alarm indicated the finishing of process and the operator removes its foot from the pedal. Both the jaws get separated and the finished product is taken out of the foot operated heat sealer.
4.What Are The Main Components Present In A Foot Operated Heat Sealer?
Main Components of a Foot Operated Heat Sealer
The main components of a foot operated heat sealer are
The most important part of a foot operated heat sealer are its top and bottom jaws. These are actually responsible for sealing of products. The product is placed in between of these jaws and during operation both these jaws get in contact which in result seal the material
- Heating Element
The temperature is maintained at the heating elements of a foot operated heat sealer. These are on the jaws of machine and are responsible to melt the product with the produced heat. The product placed at the jaws gets its sealing temperature from these heating elements. Different type and shaped heating elements are present in different types of foot operated heat sealers according to the requirement of product.
Pedal is the most important part of a foot operated heat sealer as it is responsible for the operation of machine. The operator pushes the pedal downwards and as a result an electrical signal is transferred to joint both the jaws. When the foot is removed from the pedal the jaws get separated. Pedals basically convert a mechanical signal to electrical one
- Control Panel
The operation of a foot operated heat sealer is controlled through this control panel. All the knobs and buttons like power, temperature control, regulator, switches and fuses are present in the control panel. It is in direct control of the operator and from here the operational parameters are maintained.
- Temperature Sensors
Heat sensing temperatures are found mostly in machine where temperature or heating factor is involved. Such sensitive devices are also found in automatic foot operated heat sealers because the machine has to be maintained at the given preset value. If the sensors do not perform well, the over-heating of jaws can cause irregular sealing and severe material loss.
A transformer basically controls the over and low voltage of a foot operated heat sealer and maintains the power throughout its operation. During a sudden jerk of voltage, the foot operated heat sealer can directly get affected. This is the reason a setup transformer are ideally installed in it.

8.What Are The Differences Between A Foot Operated Heat Sealer And An Ordinary Heat Sealer?
Following are the differences between a foot operated heat sealer and an ordinary or traditional heat sealer.
Foot operated heat sealer is set on a certain pressure value which remains same throughout the cycle. This results in identical sealing on all the products. Pressure also maintains the force by which both the jaws of machines get in contact. This controlled pressure reduces chances of poor sealing
While in a traditional sealer the pressure varies in each cycle depending upon the operator’s ability. The applied pressure is directly in control of the operator. As a result to this, the product shows different sealing width in each cycle.
- Sealing Quality
High quality sealing is achieved in a foot operated heat sealer. Every product in the processing line has same sealing quality.
Poor quality sealing can be done manually. In this type of machine the cycle can be repeated more than twice depending on the quality of sealing done. A lot of wastage can occur in manually operated sealing machines.
- Wide Range
A foot operated heat sealer offers wide range of material compatibility and can be set according to the width of bag. Different materials like PVC, polyethylene, aluminum foil and other materials of various sizes can easily be sealed using this type of machine.
Single machine only shows compatibility to limited material width. The manufacturer has to buy separate machine for all products. Also the machine does not gives efficient sealing if variety of materials are used.
Foot operated heat sealers are a bit expensive when compared with manual sealing machines but they can be economical in a sense that only one-time investment is carried. After that a full time benefit can be taken for longer period.
Manual machines are economical when bought but when each machine are purchased for separate material it requires a lot of initial investment. Even thickness and width of materials are also kept in concern when a manufacturer thinks of a traditional heat sealer.
The productivity also remains a greater advantage and large number of sealed products can be get from a foot operated heat sealer.
The machine depends upon the ability of its operator. The greater the operator is efficient the maximum output is gained. It always remains a direct relation in traditional sealers.
- Edge Cutting
Sharp knives and heating elements are present in a foot operated heat sealer to cut the bag after its sealing process is completed.
Manually cutting of edges is done by the operator himself. The cutting can be sometimes poor with improper edge cutting.
