Vac pack or vacuum packaging or vacuum packing is a packaging method which seals the items, especially food products, after getting rid of air from the plan. It is normally made use of for the packaging of subject to spoiling foods by sealing them in a plan made from plastic film, after getting rid of the air inside it. It can be done manually as well as automatically with devices according to the volume and function of packaging. Sometimes shrinkable films are likewise made use of for this function to keep the content snugly suited the plan. Main function of vacuum packaging is to extend the service life of subject to spoiling foods by getting rid of oxygen from the plan. It likewise minimizes the volume of plan alongwith its contents.
Reasons to choose vacuum packaging
Vacuum packaging is preferred for subject to spoiling food products as by decreasing the oxygen in the packaging it not just controls the development of fungi or bacteria in the plan however likewise avoids its volatile content from vaporizing.

How to vacuum packing the products?
Containers like canisters, plastic bags, mason containers or bottles available in houses can be made use of for vacuum packing numerous sorts of items, food or non-food. While packaging delicate items like crispy potato chips and so on to prevent their crushing during vacuum packaging oxygen inside the plan is changed with nitrogen gas. It controls the degeneration of the items in the same way as the removal of oxygen with vacuum does.
Types of Machines Used for Vacuum Packaging
Different sorts of vac pack devices are made use of for domestic as well as industrial packaging food and non-food items. They are primarily classified into 2 sections external sealing devices and internal sealing devices. Brief info about these vacuum packaging devices is offered right here under for your support.
External Sealing Machine
While packaging a product with vacuum packaging process a plastic bag is externally attached to the vacuum sealing equipment which eliminates the air in the bag and seals it. As the items are sealed outside the equipment so the equipment made use of for vacuum packaging is called external sealing equipment.
Internal Sealing Machines
Different sorts of internal sealing devices are made use of for vacuum packaging of the items consisting of single vacuum chamber devices, double vacuum chamber devices, automatic belt vacuum chamber devices and thermoforming or rollstock vacuum packaging devices.
Single vacuum chamber devices: The whole product has to be placed into the equipment while vacuum packaging it with single chamber vacuum chamber equipment. The product to be sealed is placed in a plastic bag inside the equipment and the air is eliminated after closing the cover of the equipment and the plan is heat sealed. All the staying air in the bag is squeezed by the air can be found in with an outdoors vent which automatically opens after sealing the bag. The plan is then eliminated by opening the cover of the equipment. This method is normally made use of for packaging low to medium volumes of solids as well as liquid items.
Double vacuum chamber devices: These sealing devices are typically made use of for medium volume of packaging. The whole process runs like the single vacuum chamber devices however the only distinction is that they help in enhancing the productivity of the device. Their fully automatic or spring-weighted covers typically swing from one side to the other. These devices are normally made use of for the vacuum packaging of processed meat, fresh meat, chocolates and candies, hard and soft cheese and so on.
Automatic belt vacuum chamber devices: The items are completely placed in flow covered pouches or plastic bags inside the automatic belt vacuum chamber devices which is automatically placed on the seal bar of the equipment by taking a trip on their conveyor belts. The cover is closed and the plan is sealed after getting rid of air from it. Though the whole process after sealing the product is similar to that of single or double chamber devices however its high speed conveyor belt enables you to vacuum plan large size items quickly. They can likewise be made use of for packing liquid items. The cover of these devices moves up and down during the process. They are normally made use of for packing large logs of sausage, hard and soft cheese, processed meat and fresh meat and so on
Thermoforming or rollstock vacuum packaging machines: These vacuum packaging devices are normally made use of in large manufacturing devices. The rolls of packaging film famously called webbing made use of in these devices enable you to produce vacuum stuffed items by loading the product in its thermo formed pockets where internet is put on its leading and the product is vacuum sealed. You can enhance your manufacturing with these high speed vacuum packaging devices. Different sorts of plastic internet can be made use of in these devices suitable to the items to be packed. They can be made use of for vacuum packaging of sausages, chocolate and candies, marinated and fresh meat, cheese, ready-to-eat foods like snack sticks, beef jerky etc, collectibles or coins and clinical and pharmaceutical items and so on
Hence, numerous sorts of vac pack or vacuum packaging devices are made use of to prevent the degeneration of the delicate and quickly subject to spoiling food as well as non-food items for long time after getting rid of oxygen from their plan. They primarily remove the oxygen content inside the plastic packing bags which otherwise can ruin the items in them.
