- Outside Cut Pack. This method of packaging is the most common type of packaging. In this case, the film is cut from 2 to 2.5 mm from around the tray and then packed on the opening of the tray.
- Natural Atmosphere. Packing with natural atmosphere method, in which case the product will only be safe against physical contact and mechanical impacts.
- MAP Technology. The modified atmosphere packaging method, which causes the atmosphere inside the package to be modified by the specified gas composition and finally the shape, color and freshness of the product to be preserved for a specified period of time. Carbon dioxide, nitrogen and oxygen gases are usually used to correct the atmosphere inside the packaging.
- IML Pack. Packaging food products in IML trays can create a unique beauty. IML trays are labeled during production. These types of trays have narrow edges, so they should be packaged with special technology.
- EMAP Technology. Packaging by controlling the respiration rate of the product inside the package, which is removed through micrometer holes, provides the necessary oxygen inside the package and removes excess carbon dioxide. This method can ultimately extend the shelf life of products such as fruits, vegetables, and salads.
- Easy Peel Point Pack.This type of packaging is used for products that the film should be easily removed from the tray opening during usage. Therefore, the tab created by this method can help to do this more easily.
- Hard Peel Point Pack. This type of packaging is used for products that require the film not to be easily removed from the tray during consumption. This type of packaging is done when the product is intended for export to other countries.
Skirt Out Pack. This method is used for round trays. After packaging, the film is placed in a skirt-like shape around the tray.
- Vacuum Pack. This type of packaging is among the common methods. After placing the product inside the tray, packaging is done by vacuuming, which sends the atmosphere out of it.
- Cup Pack.Packing of round trays is done by outside cut method.
- Bucket Pack. Products that must be placed in buckets should be packed by this method. The buckets usually have high heights.

Single to Multi-Row Converter and Vice Versa
In some cases, trays are filled either by specialized fillers or by multiple fillers, and it is necessary to fill them individually or in multiples. In this case, this machine can set the rows according to the production line.
Fillers can be in the following forms:
- Multihead filling machine (filler for granular products)
- Filler for powdered products
- Gravity fillers (filler for diluted liquids)
- Piston cylinder filler (filler for concentrated liquids and semi-solid heterogeneous products)
When products are in the form of diluted liquids, concentrated liquids, semi-solid heterogeneous materials, or granular solids, filling the product into trays can be done automatically and continuously by these machines, eliminating labor and preventing contamination. One of the most important advantages of using these machines is their ability to control and package the amount of product that needs to be filled into trays easily through settings on the machine.
Fillers come in several types:
- Piston Cylinder Filler: This machine is used for food products such as honey, jam, mayonnaise, sesame cream, breakfast chocolate, and date syrup. It can be equipped with a heater and mixer in its tank to prevent clogging at the connection for products that may solidify and change viscosity during filling.
- Gravity Filler: This machine is used for filling various diluted liquids into different trays, such as mineral water, yogurt, flavored drinks, and products with viscosity similar to water. The operation of the diluted liquid fillers, also known as gravity filler, is based on the gravitational force of the product, without the need for a pump or motor.
- Volumetric Filler: Volumetric fillers are used for filling various products that cannot be filled into containers by a weighing filler due to their shape and texture. In such cases, this type of filler is used. Among the products that can be filled into containers by this filler are pickled olives and fruit salads.
- Multi-head Weigher: This type of filler is used for products that are granulated. Products such as dried fruits, nuts, legumes, grains, vegetables, nuggets, falafel, and small pieces of chicken or red meat are among the products that can be filled into trays through this method. In general, this machine is used for any product whose accurate weight in packaging is important. The weighing filling machine is one of the most accurate and widely used fillers among filling machines, using a highly accurate weighing mechanism. This type of machine is equipped with very precise and sensitive scales that weigh the product with the least amount of weight tolerance.
- Automatic Rower: The automatic rower is placed at the output of the automatic machine after the outlet conveyor and put the trays in rows. In the next step, a jet printer or labeler can be installed. The jet printer can imprint the date, price, and production specifications on the tray, and the labeler has the ability to stick labels on packaged trays.

- Traffic Table (rotary table): The rotary table is placed at the end of the packaging line for gathering packaged trays. The table is made of qualified and washable 304 stainless steel.
- Metal Detector: The application of metal detectors is to detect metals inside any product, such as pharmaceuticals and food products. There is always the possibility of accidental existence of metal contamination in products, and in such cases, metal detectors are used as a control system. Therefore, metal detectors play a very important role in the quality control system of packaged products.
- Check Weigher Systems: Check weighers are used to control the weight of products. If the weight is less or more than your desired amount, the package will be automatically removed from the line. These machines are placed at the input and output of the tray sealer (seal vacuum) machine. They also have the capability to calculate the price of the product based on its weight automatically and transfer the data to a jet printer for instant price imprinting on the packaging.
