Description

Fermented Food Packaging Container {FERMENTATION FOOD PACKING CONTAINER}

The present invention relates to a fermented food packaging container that can maintain the fermentation breath of food after packaging.

Conventional fermented food packaging containers are sealed with a sealing film (breaking film) that allows the opening of a non-breathable packaging container such as a synthetic resin container or a glass container containing food to be opened and opened when first used.

Figure 1 cited the configuration of the open-film film coated with a synthetic resin layer on aluminum foil in order to seal the inlet of the conventional fermented food packaging container. 1 is a composite film in which a polyester film or a polypropylene film layer 41 is stacked on an intermediate layer aluminum foil 40 and a polyethylene film layer 42 is stacked below.

In FIG. 2, the fermented food packaging container using the open-film film composite of FIG. 1 was cited. In FIG. 2, the open film 55 is attached to the inlet of the container 43 containing fermented foods 46 such as miso and red pepper paste. When the packaged food 46 is used, the open film 55 is torn off, but in the distribution process, the film 44 blocks the airtight distribution at the inlet of the container, and the fermented food 46 is choked.

In some cases, the cover 45 is covered at the inlet of the container 43.

As described above, the conventional blasting film is a suffocating film that completely blocks the ingress of external air and moisture, and in addition to the above-mentioned composite, a moisture and air barrier suffocating film including aluminum foil, aluminum deposition film, nylon or EVOH film layer is used. Sometimes.

As mentioned above, the conventional fermented food packaging container is a non-breathable suffocating package that does not consider the fermentation progress of the food. Choking packaging of fermented foods causes various problems due to the failure to release fermentation gas generated after packaging. Listing the problems shortens the shelf life of the food. The gas pressure inside the container is increased to expand the packaging film. In a packaged state, fermented foods do not allow natural fermentation to proceed. Prolonged suffocation of packaging changes the interior of the container to an anaerobic fermentation environment, altering the packaged food. Choking and packaging fermented foods in this way will not preserve the freshness and taste of the foods in the long term. In Korean Utility Model Publication No. 97-54651, a part of the open film of the choking packaging container is provided with a vent and Although the permeable ventilation nonwoven fabric is made to adhere, it is questioned whether the nonwoven fabric can provide liquid impermeability.

The present invention is an invention for improving the above disadvantages.

An object of the present invention is to provide a fermented food packaging container consisting of a breathable film composite to ensure the fermentation breathing of the whole or part of the food packaging container, in particular, the opening of the container in packaging the fermented food. .

Another object of the present invention is to provide a breathable film composite laminated with a nonwoven fabric in order to ensure breathability in the uniaxially stretched breathable film and at the same time maintain the sealing strength.

Another object of the present invention is to use a package to protect the fermentation breathing, the fermented food can proceed the fermentation slowly even after packaging can prolong the packaging period, do not expand the swelling film, long-term taste and freshness of the food The purpose is to provide a fermented food packaging container to maintain.

The present invention improved the packaging of fermented food as follows.

Figure 3 shows the configuration of the composite film for fermented food packaging of the present invention.

The light shielding film composite 3 for protecting the fermentation breath of the fermented food is obtained by laminating the light shielding breathable film 3a and the nonwoven fabric 3b. The breathable film has a thickness of 20 to 100 µm and the nonwoven fabric has a thickness of 150 to 300 µm. In the Example, the thickness of a breathable film was 30 micrometers, and the thickness of a nonwoven fabric was 250 micrometers (30 g / m <2>), and the good result was obtained.

The air permeability of the light-shielding film composite 3 is set to 200 to 1500 g / 24 hr · m 2 (test method ASTM E-96) based on the measurement of moisture permeability.

If the air permeability of the breathable film (3a) is large, it can smell the fermented food outside the container, if the air permeability is too low, the fermentation breathing is poor. However, the breathable film does not leak water even if the air permeability is increased, but it is better to allow a slight odor release to keep the fermentation breathing active. In the example, the smell of kimchi was detected in the sensory test when using a film having a water permeability of 1250 g / 24hr · m 2. When the water permeability was 600g / 24hr · m 2, fermentation breathing and storage were good. If it is not a special use, the objective of this invention can be achieved with the film of 200-600g / 24hr * m <2> of water permeability.

The breathable film 3a is formed by adding 30-65% (weight ratio) of inorganic materials such as CaCO ₃ and BaSO ₄ to the polyolefin-based polymer, and then stretching the film to form fine pores such that water does not leak into the film. A breathable film can be obtained. Air or moisture passing through the film is moved from the higher pressure side to the lower pressure side. When the breathable film is used as a packaging material of the fermented food, the gas inside is mainly emitted to the outside, and the incidence of direct sunlight is blocked by the scattering effect of the milky white breathable film. In this way, the environment inside the package made of the light-shielding breathable film is similar to that of traditional poisoning.

4 shows an adhesive application pattern for laminating the breathable film 3a and the nonwoven fabric 3b in the breathable film composite 3. When the adhesive is applied to the entire surface of the laminated surface of the composite 3, the air permeability of the film and the nonwoven fabric is lost, so in the embodiment, the adhesive 4 is applied in a cross-hatched pattern to bond the film 3a and the nonwoven fabric 3b and at the same time The breathability of the nonwoven fabric was maintained. Polyurethane-based adhesives were used in the examples as non-toxic adhesives used for adhesion of the film and the nonwoven fabric.

In FIG. 5, the inlet of the container 1 containing the fermented food product 5 is sealed as the inventive breathable film composite 3. The hot melt adhesive 2 was used as a sealing means.

In FIG. 5, the inlet of the container 1 is sealed as the light-shielding breathable film composite 3 so that the fermented food 5 does not spill out of the container 1 or the liquid contained in the food does not leak. By discharging the gas generated from the fermented food to the outside and at the same time blocking the incidence of direct sunlight is to maintain the fermentation conditions of the fermented food.

6, a far-infrared radiation container 1a is produced to contain fermented food 5, to seal the inlet of the container 1a with the hot melt adhesive 2 and the light-shielding breathable film composite 3, and to the container 1a. The cover 7 in which the small vent hole 6 was arranged in () was covered.

In the far-infrared radiation container 1a of FIG. 6, 0.5 to 70% (by weight) of at least one inorganic material selected from mica, antibacterial ceramic, CaCo ₃ , BaSO ₄ , SiO ₂ , and talc is added to a polymer having a melting point of less than 300 ° C. It is melted and molded into a container, and the far-infrared radiation container can preserve the taste of fermented foods and extend the shelf life of packaged foods, like traditional long venom.

In FIG. 6, when the inlet of the packaging container 1a is sealed with the light-shielding breathable film composite 3, incidence of direct sunlight is blocked, and gas generated from the fermented food is discharged through the breathable film, but liquid leakage is prevented to transport the packaged food. Of the fermented food packaged with far-infrared rays which prevents leaking or spilling of raw foods, and covers the breathable film composite 3 by arranging holes 6 of 0.3 mm or more, and emits from the far-infrared radiator container 1a. It will activate the potency.

In the present invention, the breathable film composite may be used as a fermented food packaging container such as miso and red pepper paste in a bag form.

Example 1:

(a) Compound containing 45% (by weight) of CaCO ₃ and 10% (by weight) of BaSO ₄ in the polyester was dissolved in an extruder arranged in four stages of 210 ° C, 230 ° C, 250 ° C and 250 ° C, followed by T-die. After obtaining a film having a thickness of 100㎛ through and stretched twice in the machine direction to obtain a light-shielding breathable film having a moisture permeability of 1500g / 24hr ㎡ (ASTM E-96),

(b) The nonwoven fabric (30 g / m <2>) was laminated | stacked on said (a) breathable film in the pattern of FIG. 4, and the breathable film composite was obtained.
