Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a sterile packaging film and a sterile packaging method.
Furthermore, B: L, < means that the inside of the film is essentially sterile, making it suitable for aseptic packaging of sterilized contents! After sterilizing the aseptic packaging film J, which is made of blown film, and using it to introduce the tube into the aseptic packaging device in the sterilization process, cut the edges Iυ1 and make it into a sheet shape. The present invention relates to a method of aseptic packaging in which sterilized contents are packaged in one package.

1. "Aseptic packaging" refers to sterilizing the container in advance, filling the container with the contents under aseptic conditions, and sealing the container.

Aseptic packaging is used for long-term storage foods such as conventional canned or bottled foods, or bulk foods that require sterilization after filling the contents tightly. It has the great advantage that there is no need to secondary heat the contents such as food. Therefore, there is no quality deterioration in the taste, which is the basis of the tilli value of food products, and the product is packaged in 4. II, 1 as 11iJ!

The entry of fc bacteria into /iL is also difficult to completely stop no matter how harsh the method.

For this reason, conventionally, some amount of staining that occurs during manufacturing has been considered unavoidable.
Although it had been used to prevent the use of food additives such as wound killers and preservatives, it may be due to toxicity restrictions on the use of food additives such as wound killers and preservatives.2

For these reasons, 4J waste,

There is a problem that scratches on the surface may occur, and conversely, if the adhesive is weak, the film may peel off during bamboo preservation and become contaminated with bacteria.

Accordingly, an object of the present invention is to eliminate the problems of the prior art described above by one to one, and to effectively and economically wipe out the contents of foods, etc. (1°C 12'1 1.3 To provide a sterile packaging film that can be wrapped and a packaging method.
