Description

A packaging module for both vacuum packaging and skin packaging and a packaging machine for both vacuum and skin including the same {A packaging module for both vacuum and skin packaging and a packaging machine for both vacuum and skin}

The present invention relates to packaging machines for food, etc., and more specifically, to a packaging module for both vacuum packaging and skin packaging that can perform vacuum packaging and skin packaging by simple and easy replacement of the vacuum packaging module and skin packaging module, and the same. This is about a vacuum and skin packaging machine.

This part only provides background information related to the content of this application and does not necessarily constitute prior art.

Food packaging technologies include vacuum packaging and skin packaging.

Vacuum (map) packaging is a method of packaging meat using an air-impermeable nylon-PE film and removing the internal air, and is often used in frozen meat packaging. The vacuum packaging method has the advantage of maintaining the shape of the product and preventing changes in the shape of the product during the distribution process.

Skin packaging involves placing a solid packaging product in a container such as paper, cardboard, or plastic sheet, covering it with a preheated plastic film to degas it, and strongly adhering the film to the shape of the packaging product, thereby bonding the surrounding film to the container. This is a packaging method that attaches the plastic film to the container by heating and softening it and then degassing the base sheet under reduced pressure to strongly adhere the plastic film to the packaging object and the container. Exhausting is the removal of air from an object or environment and has important significance in the production of processed foods. By removing air from the food itself or the surrounding environment, oxidation of fat, oxidation of vitamins, oxidative browning, non-oxic browning, and internal surface corrosion can be prevented.

Registered Patent No. 10-1596773 is a packaging container made of a foamed PSP material made by mixing PSP (Polystyrene paper) and a barrier film, which is seated and fixed, and includes a mold base part that is installed to be able to move forward and backward; a film providing unit that positions a protective film on the upper surface of the mold base unit 20; It is installed to be able to move up and down at the top of the mold base, and is in contact with the mold base, and the protective film is fused to the rim of the packaging container for skin packaging, or the inside of the packaging container is vacuumed and preset. It is a packaging machine composed of a chamber part that creates map packaging by fusing a protective film to the rim of the packaging container after injecting gas. It is used for both skin packaging and map packaging, but each packaging module (vacuum packaging module, skin packaging module) is used. It is not a replacement method and the configuration is very complicated.
