の蒸散も、生鮮食品の鮮度低下の原因となる。 Deterioration in the freshness of fresh foods occurs due to overheating due to ethylene gas generated from fruits and vegetables, condensation of water vapor due to respiration, etc. when the fruits and vegetables are packed in boxes, bags, etc. in closed or nearly closed conditions. In fish, for example, it occurs due to the removal of juice from meat and fish during tray packaging. Excessive transpiration of water also causes a decrease in the freshness of fresh foods.

ものである。 Recently, attention has been focused on these causes of deterioration in freshness, and attempts have been made to use freshness sheets for fresh foods. This type of freshness preservation sheet has a powdery gas or moisture absorbent sandwiched between a surface material made of paper or nonwoven fabric, and is coated with an acrylic or urethane emulsion adhesive, a thermoplastic resin such as polyethylene, etc. It is integrated using powder or fiber as a binder.

た。 However, since such freshness-preserving sheets use a binder, the surface of the gas adsorbent or moisture absorbent is partially covered by the binder, resulting in a decrease in freshness-preserving performance. It was hot. Moreover, the paper or nonwoven fabric used as the surface material was thin, had no cushioning properties, and had poor moisture control performance. Furthermore, when manufacturing a freshness preservation sheet, even if the powder of a gas adsorbent or water absorbent is uniformly spread on the surface of paper or nonwoven fabric, the powder is easy to move and is evenly clamped. It was difficult to do so.
本考案は、上述の如き従来の鮮度保持シートの

る。 The core material 1 is sandwiched between surface materials 2 and 2' made of paper or nonwoven fabric, and integrated by heat embossing. The surface material 2 covers and protects the mixed layer of gas adsorbent and superabsorbent polymer material that makes up the core material 1, reinforces the weak strength of the nonwoven mat that makes up the cell 1, and further absorbs the generated gas. and for absorbing moisture into the core material. Therefore, the surface materials 2, 2' are made of paper or nonwoven fabric having air permeability, water permeability, and appropriate strength, and the paper has a basis weight of about 20 to 100 g/ m2 , Nonwoven fabrics are made of synthetic fibers such as polyester, polyethylene, and polypropylene with a basis weight of 20.
~100g/ m2 non-woven fabric is used. 31
32 is a concave pattern of the freshness preservation sheet 3 integrated by heat embossing, and 32 is an embossed pattern.

させることができる。 In addition, since a mixed layer of gas adsorbent and super absorbent polymer material is provided on one side of the non-woven mat, moisture such as water vapor generated from fresh food can be absorbed through the surface material. It is quickly absorbed by the polymer material, and the gas adsorbent is less susceptible to gas adsorption damage caused by water vapor, and the adsorption function of gases such as ethylene gas does not deteriorate, allowing the adsorption effect to last for a long time. .

も優れた鮮度保持シートが得られる。 Furthermore, in the present invention, the core material is sandwiched between the surface materials and integrated by heat embossing treatment, and the cellulose fiber nonwoven mat has bulky and soft properties. Because of this,
The gas adsorbent and superabsorbent polymer material powder that is sprinkled on top of this material will not move or become uneven during manufacturing, and will be stably and evenly sandwiched between the surface materials. Moreover, since the protrusions of the heated embossing roll press strongly, the bulky non-woven mat is uniformly hardened as a whole, together with the mixed layer of gas adsorbent and super absorbent polymer material, and the surface material, and the binder is removed. A freshness-keeping sheet can be obtained that is strongly integrated even without use, does not peel off during use, can prevent deterioration in gas adsorption performance due to the use of a binder, and has an excellent buffering effect.
