Considering the great variety that exists among food products, for example: storage temperatures, microbial flora and different respiration rates, etc., the packaging technology of each product must be carefully selected.
The modified atmosphere technology of automatic seal vacuum (tray sealer) machines can increase the shelf life and quality of the product by changing the natural air composition inside the packaging. In this technology, the percentage of O2, CO2, and N2 gases is adjusted according to the composition of the food material in the packaging, so that the shelf life of the product increases significantly.
This technology is used in the manufactured machines of the Knowledge-Based West Asia Steel Company in a completely professional manner and is one of the most important features of the packaging machines of this company.
The procedure of this technology is as follows: a part of the air inside the tray that has reached the mold of the machine is sent out (vacuum), then a gas suitable for the product is injected into the tray, and ultimately, the film is sealed on the tray so that the modified atmosphere inside the tray remains. The combination of this method, which is vacuum and gas injection (MAP), is the most important technology used in automatic tray sealer machines.
This packaging operates by controlling of the product's respiration rate inside the package (EMAP technology). Oxygen is supplied to the package through micrometer-sized holes, and excess carbon dioxide is sent out. Eventually, this method can significantly increase the shelf life of products such as fruits, vegetables, and salads.
In this type of packaging, the product is secure only toward physical contacts and mechanical effects.
Vacuum Packaging is one of the common methods. After being placed inside the tray, the product is packed by a vacuum that causes the atmosphere to send out of it.
Inside-cut packaging makes the film have no borders around the tray and the beauty of the packaging increases significantly.
West Asia Steel is the only company in the country that can provide customers an automatic tray sealer packaging machine by capability of packaging using inside cut method.
Outside cut pack is the most common type of packing. In this case, the film is cut at a distance of 2 to 2.5 mm from around the tray and then it is sealed on the packaging tray.
This type of packaging is used for products that requires the film to be easily peeled off the tray during consumption. Therefore, the tab created by this method can greatly makes this task easier.
This type of packaging is used for products which film should not open during consumption (specially products which should export or send to other cities, in other words packages should place on each other for a long time).
Packaging food products using the in-mold labeling (IML) method can create a unique beauty. IML trays have labels molded into them during manufacturing. These trays have narrow edges, so their packaging must have special technology.
The vacuum packaging method is one of the common methods. After the product is placed inside the tray, it is packaged by vacuuming (sending out) the atmosphere from inside of the package.
This method (Skirt out pack) is used for cup trays. After packaging, the film is placed in a skirt shape around the tray.
This packaging method is a combination of the Peel Point and Inside Cut methods. In this method, the film is cut inside the edge of the tray and then a tab is created next to it to make it easier for the consumer to peel the film of the tray.
Products which need to be placed inside a bucket are packaged using this method (Bucket pack). Usually, buckets have a high height.
Packaging of cup trays by outside cut is done by this method.
Skin Pack packaging is one of the most attractive packaging methods in the industry. In this method, the product is vacuum-sealed to reduce biochemical degradation due to sending the air from inside of package. After packaging, the product is securely placed in its position and all surfaces of the product are covered with a film.
Different types of skin packaging by considering the shape:
One of the packaging methods for improving product sales is Hanging Pack packaging. After packaging, the trays are hung on store shelves for better showing to customer.
For packaging trays with very narrow cut width, the Smooth Cutting Edge packaging method can be used.
