(Industrial Application Field) This proposal relates to packaging materials for cheese, specifically, individual packaging materials for natural cheese, especially camembert cheese. (Prior Art) Conventionally, polyethylene and laminate nonwoven fabrics have been used as packaging materials for camembert cheese. Polyethylene is used because it has adequate air permeability and permeates oxygen and water vapor, which controls the respiration of the cheese and promotes mold growth. In addition, since the nonwoven fabric absorbs free water (whey) from cheese, the whey generated during cheese ripening is absorbed, resulting in uniform growth of mold. (Problems to be solved by the invention) However, the above packaging materials have the following drawbacks. That is, when cheese is wrapped on the non-woven fabric side, the white mold of camembert cheese becomes embedded in the fibers, and the wrapping paper cannot be peeled off cleanly. Furthermore, if cheese is packaged on the polyethylene laminate side, whey will be difficult to absorb, making it difficult for white mold to grow uniformly. (Means for solving the problem) Therefore, the technical problem of this proposal is to create a packaging material that can be peeled cleanly from cheese, prevents drying and thinning of cheese, and promotes the growth of mold uniformly on the surface of cheese. The aim is to provide materials. The technical means of the present invention to solve this technical problem is to layer breathable plastic films on both sides of the non-woven fabric, and the plastic film that forms the inside of the packaging prevents the mildew that grows on the surface of the cheese from biting into the non-woven fabric. It is intended to prevent
The inner plastic film is provided with a large number of holes to allow whey released from the cheese to pass through the nonwoven fabric. (Function) In the cheese packaging material of the present invention, cheese is packaged with the side in which many holes are formed inside. Therefore, there is no contact between the packaged cheese and the nonwoven fabric. On the other hand, whey released from the cheese is absorbed into the nonwoven fabric through holes made in the inner film. (Example) An example of the above-mentioned present invention will be described based on the drawings. 1 is a non-woven rayon paper made by mixing wood pulp with 50% or more of rayon fibers cut with a rotary cutter, and has a lower density than paper. However, it is breathable. 2 and 3 are plastic films with appropriate air permeability, such as polyethylene films, which are laminated on the inside and outside of the nonwoven fabric. The thickness of the nonwoven fabric is 10 to 200 g/m 2 and the thickness of the polyethylene film is 10 to 100 μm.
Therefore, the inner polyethylene film 2 that comes into contact with the cheese 5 has a diameter, major axis, or length of 0.1
A large number of circular, elliptical, or linear holes 4 of about 5 mm in diameter, for example, 1 to 100 holes/cm 2 are uniformly provided. When cheese is packaged as shown in FIG. 4 with the film 2 inside using a laminated packaging material in which the plastic films 2 and 3 are laminated to the nonwoven fabric 1 as described above, the nonwoven fabric 1 and the polyethylene films 2 and 3 are packaged.
The breathability of the cheese can moderately control the breathing of the cheese and prevent the cheese from drying out. Moreover, the whey released from the cheese 5 passes through the holes 4 formed in the inner film 2 to the nonwoven fabric 1.
Since it is absorbed by the cheese 5, uniform growth of mold can be promoted on the surface of the cheese 5. However, since the inner film 2 is in between,
The cheese 5 and the nonwoven fabric 1 do not come into direct contact, and the white mold that grows on the surface of the cheese does not become entangled in the fibers of the nonwoven fabric. Therefore, when the package is opened, the mold does not separate from the cheese, and the peelability is good.
Note that 6 indicates a sealing tape. By the way, when we conducted storage tests using wax-treated non-woven fabrics on the inside or non-porous polyethylene laminated to non-woven fabrics as packaging materials, we found that mold grew uniformly due to the influence of whey generated during cheese ripening. The surface of the cheese turned yellow. However, in the case of the present invention, white mold easily grew, and the peelability when opening was also good, and the appearance of the product was maintained despite the presence of mold. The following examples will be given to demonstrate how superior the proposed method is. (1) Test packaging material A...Perforated polyethylene/rayon nonwoven fabric (20μ) (17g/ m2 )/Polyethylene (15μ) Pore diameter φ2.5mm/piece Number of holes 5/ cm2 B...Rayon nonwoven fabric/polyethylene (17g) /m 2 ) (15μ) A method of packaging the cheese with the rayon nonwoven fabric side in contact with the cheese and a method of packaging the cheese with the polyethylene side were investigated. (2) Test cheese Camembert cheese (raw type) (3) Experimental results 1 Weight change The weight loss rate was determined when the cheese was packaged, when the cheese was aged for 10 days in a fermentation room, and at 5℃ for the cheese expiration period. , when stored for 2 weeks, showed the symbol B>A. However, the difference was not particularly problematic (see Data Table 1). 2 Peelability When cheese is packaged using packaging material A with the perforated film on the inside, it has good peelability and no damage from mold that has grown on the surface of the cheese (transfer of mold to the packaging material) is observed. Ta. In the packaging material B, mold adhered to the packaging material and peelability was poor. 3 Appearance There were no problems with the packaging material of A. Cheese wrapped in packaging material B with non-woven fabric inside:
Mold that grows on the surface of the cheese is transferred to the packaging material,
Product value was inferior. On the other hand, when cheese was packaged with packaging material B on the polyethylene side, mold growth was poor and the surface of the cheese turned yellow.

[Table] (Effects of the invention) In any case, according to the cheese packaging material of the present invention, the whey released from the cheese is absorbed into the nonwoven fabric through the holes in the inner film, resulting in uniform growth of white mold. There is no problem of yellowing of the cheese surface. Furthermore, since the surface of the cheese with the film in between does not come into direct contact with the nonwoven fabric, the white mold that grows on the surface of the cheese does not become entangled in the fibers of the nonwoven fabric. Therefore, when the package is opened, the mold does not peel off as compared to cheese, and since the peelability is good, the product value does not decrease. In addition, since the plastic film has appropriate air permeability, together with the air permeability of the nonwoven fabric, the breathing of the cheese is controlled, making it possible to obtain fresh cheese.
