Use

1. Cutting the Sheet to the Size You Want

Cut HIYASYANSE (or Hiecon) to the size you want along the perforations.

(You may cut the sheets after they have absorbed water).

2. Immersing the Sheets in Water
(for 5 to 10 minutes)

Fill a tub with tap water, place the sheets in the tub with the white sides up (the sides on which no characters are printed), and then leave the sheets in the water for five to 10 minutes.

After the sheets have grown to an adequate thickness, take the sheets out of the water and then leave them until the surfaces of the white sides become dry.
After these surfaces have dried, place the sheets in the freezer.

3. Freezing the Sheets

Stack HIYASYANSE (or Hiecon) sheets in the freezer with the white sides and printed sides facing each other, and then freeze them.

The freezing is complete when the sheets have become as hard as ice.

4. Wrapping Foods with the Product
for Delivery
Even if foods are delivered using a freezer truck, the temperature changes during the time the foods are handed to the recipients.

Such fluctuations in the temperature cause changes in the taste of the foods. However, you need not worry if the cooling sheets are used.

They maintain the flavor of the foods.

5. Delivery

HIYASYANSE (or Hiecon) is Eco-friendly and Easy to Dispose of.	HIYASYANSE (or Hiecon) is Non-toxic.
Because most of the water in the packs evaporates several days after use, disposal or incineration can easily be performed. In addition, fuel costs for incineration can be kept down.	Although the contents of the packs, which are composed of highly water-absorbent resin, are harmless to the human body they should not be eaten (i.e. if the resin has adhered to a part of the body or to food after the pack has been mistakenly torn or accidentally broken, please wash it away in tap water).
