• Thermostats are there to maintain the temperature of hot plate depending upon the category of wrapping material used.
• The film roll is also set according to the material which has to be wrapped and best fits the product.
• Now when all the parameters are set, the machine is allowed to preheat for 5 to 10 minutes so that it can smoothly run from the first product.

• Place the product on the cover plate and pull the film out to cover and wrap the product. In automatic process the machine itself performs this task.
• Then cutoff the bar to cut the film to the desired length of product. After that the product is placed onto the teflon coated hot plate where the product will be completely wrapped and sealed in 3 to 5 minutes.
• Airtight and sealed product is produced with efficiency and precision.

4.Describe the Structure Of the Cling Film Wrapping Machine?

The structure of a cling film wrapping machine is made up stainless steel to make it durable and long lasting. It is mainly consisting of heating system, stretching system, conveying system, induction conveying system, sealing system and some of the components in a cling film wrapping machine are controllers. Detail for some of the components is as follow

Power Supply

The initial power supply is given to the machine through this power supply unit which activates all the accessories in a cling film wrapping machine.

Controlling Knobs

As the machine gets operated all the parameters like temperature, pressure, conveying speed, reset box, roller speed, and release door time all are controlled through these controlling knobs.

Constant temperature heating knobs, quick release door knob, film roller positioning knob, quick release knob all are present on a cling film wrapping machine to maintain machines process.

Feeding Bracket

At the inlet, a feeding bracket or platform is there from where the product is feed into the system.

Conveying System

As the product is placed on the feeding platform, the operation of conveying system starts. Induction conveying system is there to enter the product automatically in to the wrapping platform and the release conveying system send the wrapped product back after process completion.

Film Roller

Here the cling film roller is placed which is used for wrapping purpose. This roller allows any type of roller irrespective of its size, length and diameter.

Wrapping Platform

This is the main unit of a cling film wrapping machine in which the wrapping is done. As the induction of product is done this platform rolls the film around the product and then automatically cut the film with perfection.

5.What Are the Different Types Of Cling Film Wrapping Machines?

There are three main types of cling film wrapping machines including manual cling film wrapping machine, semi-automatic cling film wrapping machine and fully automatic cling film wrapping machine.

Manual Cling Film Wrapping Machine

In a manual cling film wrapping machine, complete process is carried by the operator. The product is placed in tray and then manually the wrapping film of covered over the product.

The operator stretches the film over the product and wrapping is carried out. Further the product is placed on the heating plate to complete seal the wrapping film. The productivity is much slow as only 50-60 products can be wrapped in a complete hour.

Semi-Automatic Cling Film Wrapping Machine

In a semi-automatic cling film wrapping machine, both the operator and machine mutually perform their responsibilities. The worker is responsible to place the product on inlet station and then the machine itself wraps the sheet around it. The excess film is cut by the operator.

Then similar to manual cling film wrapping machine, the product is placed on heating plate for proper sealing. More than 150 trays can be produce using a semi-automatic cling film wrapping machine.

Fully Automatic Cling Film Wrapping Machine

A fully automatic cling film wrapping machine is almost same as a semi-automatic s cling film wrapping machine. The only difference is that here the extra film is also cut down by the machine itself.

Rest a single operate can produce for a longer time without any hurdle. Around 200-250 wrapped products can be obtained using a fully automatic cling film wrapping machine.

6.What Material Is Cling Film Made Of?

A cling film act as a wrap on material to increase their live and safe them from the environmental conditions. In this regard high level of study is required for selecting the right material composition. After several experiments, Scientist discovered that some static charges must be present on wrapping film to work well. This allows the film to properly stick on the product and gets all the gases out.

In this regard it was suggested that due to high molecular structure, polyvinylidene chloride (PVDC) plastic is best suitable for sticking on material and to maintain the concept. Nowadays most commonly polyvinyl chloride (PVC) is used because of its low-density nature and can tightly bound with the body of material. Series of polymers make the plastic to perform well and block all type of moisture and odors.

7.What Are The Advantages Of Cling Film Wrapping Machines?
