Thermoforming packaging machine

Advantages of the thermoforming packaging machine by Packen

• High-quality and strong sealing
• Accurate and unique cutting systems
• The control panel of the machine is easily movable and accessible.
• Operator safety is ensured during the use of the machine.
• Mold changing and settings are simple.
• The structure, frame, and connections are made of durable stainless steel.

Operation of the thermoforming machine

• The thermoforming machine can package products inside plastic trays. The difference between this machine and tray sealers (seal vacuum machines) is that thermoforming machines manufacture the tray too. The film is placed in the machine and then formed by a forming mold, additionally, the packaging takes shape in the next stage and finally is cut in the final mold.
• This machine can be equipped with a UV tunnel and various types of fillers, after the products are filled into the trays, they are guided to the sealing mold, if it is necessary, vacuuming and gas injection take place. Subsequently, the film is sealed onto the tray, then cut in the next stage, and finally is moved out of the machine.
• At the end of the machine, an automatic rower, jet printer, traffic table, and even an automatic lidder can be installed to complete the packaging line.

Film of the machine

Dietary diversity is expanding, and consequently, types of packaging are also increasing. Therefore, it can be said that each packaging method has its place on supermarket shelves. Packen Machinery Company provides various packaging solutions in trays and plastic pouches

The following films can be used in packaging by thermoforming machines.

• Soft and flexible film
• Hard film (such as disposable trays)

Packaging methods

Simple packaging method

In this method, the focus is on packing the product in a simple way and protecting it against environmental pollution and possible damages.

Packaging with vacuum method

In this method, the product is completely vacuumed and biochemical degradation is reduced.

Packing with modified atmosphere method (MAP)

The atmosphere in the tray is replaced by a specific gaseous compound to extend the shelf life of the product.

For example, the gaseous composition of carbon dioxide, nitrogen and in some cases, oxygen can be used, causing the color and shape of the product to be preserved for a longer period of time.

Packaging by Skin Method

Your product is packed by a film that is placed in the form of a shell on it. This coating, while having transparency and attractiveness, can minimize the atmosphere inside the package and keep the freshness of the product for a longer time.

Packaging with skin method has different types:

• Low
• Medium
• High

Cutting system of the machine

Cutting system in thermoforming packaging machine of Packen machinery Company can be done by the following method

Transverse and longitudinal cutting by blade

This method is used for quadrangle trays. In this case, the corners of the tray will be sharp, and the machine settings will be easier to manufacture a tray with other dimensions.

Transverse cutting by Punch and Die block – longitudinal cutting by blade

In this method, transverse cutting of containers can be done by Punch and Die block with a special form, then their longitudinal cutting is done by circular blades that are rotating.

Complete cut by Punch and Die block

This method can be used for trays with special shapes. The tray can has any shape, as there is no limit to cutting.

All cuttings can also include:

• Zigzag Cutter
• Pendant hole
• a point for easier removal of the film from the tray
