Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a packaging method for herring roe, which is excellent in storage in lhT and prevents movement or uneven distribution within the container.
It depends on the packaging method of children.

Conventionally, the most common method for packaging herring roe is to place the herring roe in a tray made of G1 foamed polystyrene and shrink wrap it with a film.

However, because this method does not provide sufficient airtightness, the herring roe suffers from severe browning due to oxidation, loss of weight, and even vomiting! ! 15. The lack of power that i:F also decreases (Ai)
.

In order to prevent such m5 phenomenon, it is necessary to keep Masa's child at -7 at low temperatures below -15°C, but Masa's child is =;: fnj product. Due to this, the cost of freezing has become high, making it difficult to supply it at a low price. In addition, 91.0% for flow at room temperature, +l work 1 and sales. Browning and loss of color occur, and the quality is reduced to 1. 'f1 thing is very [11σI[
Met.

The present inventors have already proposed a food packaging method that eliminates these drawbacks by using mP with an oxygen-absorbing side2)6, but when packaging herring roe, 1. If you seal 7 pieces without letting the herring roe come into contact with each other, the roe arranged in the container will move and become disordered when packed in 1 + 'j'iN sending 11.v', which has the disadvantage of reducing the product value. - In the unlikely event that the Kazuo+4 film comes into contact with a regular child, the size of the Kazuko is uneven, so the Kazuko film may partially protrude, or some of the Kazuko may not be fixed. (Along with this, wrinkles may occur on the sealing surface of the film.)

The present invention provides a method for packaging herring roe that actually eliminates the above-mentioned drawbacks. That is, the present invention is a container body formed of a multi-layer Tl'J construction 4'' made of a resin with excellent grade permeation resistance F1 and a polypropylene resin, and an open-cell foam in the coexistence of a deoxidizing laxative. This method of packaging herring roe includes placing the herring roe on an underlayment, placing the herring roe therein, and then tightly sealing the herring roe with a lidding film made of a resin with excellent n9 resistance and permeability.

The container body used in the present invention is made of a multilayer resin made of resin and polypropylene resin, which has excellent acid resistance and window permeability, as described above.

Here, it has excellent transmission resistance t'b (1'4 resin has no particular limit, such as ethylene-vinegar, saponified vinyl copolymer, polyvinylidene, polyacrylonitrile, polyester, polyester, etc.). Examples of polypropylene resins include I11-1R combinations of propylene, as well as run forces of propylene and ethylene and α-olefins with 4 carbon atoms.

Container body G used in the present invention; t : A laminated sheet is made into a 4"CS by co-extrusion molding of 4I'1III, which has excellent permeability, and a polypropylene resin.
This is then molded into a shape most suitable for the product to be packaged using thermoforming means such as vacuum, compressed air, and C. In addition to the two-layered container body (1 layer), if necessary, the outer layer may be made of polypropylene resin, or may be made of a material other than polypropylene-based grease, etc. For example, polyprolene-based resin may be used.

In addition, 1 film of gold 5-tones such as Anotominium + 7f Q-Finotom.

It will be done.

The container shown in Figure 1 has the advantage that it can be produced economically.The container that received the 21st Prize has high torsional strength, is easy to handle, has high compressive strength, and has a dimensional accuracy of 1
It is. In addition, the pedestal is too small for sealing with a rotting film, and it still has good ITZii resistance, so it has the advantage of being excellent in stacking and storage.

L. Place into the container body in the presence of the above oxygen scavenger. Here, when it comes to open-cell foaming, 1 (♀'r polyurethane, etc.) is used, and the thickness of the underlay is approximately 1.5 to 2 times that of the finished product. Thinking about b, r, etc.
No decision error is good. By using the underlay, it is possible to arrange the ΣC eggs in an attractive manner and prevent them from moving within the container. In addition, when the lower qf (6) is water-absorbing, it is preferable to interpose a non-water-absorbing fillet (sheet) between the underlay and the herring number.

After storing the herring roe in the container body in the presence of an oxygen scavenger as described above, the Nt (film) made of wood or resin with excellent resistance to oxidation is removed. There are various types of cover film used here, such as polyamide film and polyamide film coated with vinylidene chloride.

Saponified ethylene-vinyl acetate copolymer film.

Examples include vinylidene chloride foot polyester film, polyvinylidene chloride film, etc. These films can be used not only as single layer films but also as laminated films of 2'f+'t+ or more. Furthermore, in order to improve the heat sealability with the container body, laminated films with polyethylene film, ethylene-ri'pl'i''2 vinyl copolymer film, ionomer<01 Jli? film, polypropylene film, etc. are preferably used. used.

Sealing with the lidding film can be performed by various methods, but preferably by a heat sealing method or a method using a pressure-sensitive adhesive. Here, as shown in FIG.
Deaeration 7j is performed before sealing, and the occurrence of wrinkles in the cover film and sealing performance can be improved.

By the method of the present invention, 11 containers with oxygen resistance j%
It is made of a multi-layered material made of 4'l'' + 'j' and polypropylene-based fat, which has excellent strength, rigidity, and transparency resistance. cave,
It has excellent water resistance, 1111 resistance, heat resistance f1, etc., and also contains fli'i'7 ingredients, so it can be stored stably for a long period of time without deteriorating the quality of herring roe. I can do it.

Moreover, the herring roe stored in the container body is difficult to move or unevenly distributed and is arranged in an orderly manner, so the product value is high.

In addition, from a process standpoint, the present invention has the advantage that the storage process of the beams and the process under sealing with F4T4 film can be carried out continuously and efficiently.Moreover, When a material film is sealed by heat sealing, the film does not wrinkle and has excellent sealing performance.

Next, implementation of the present invention (IJ) will be explained.
