Various new types of food packaging paper (thermal energy)

Normal align=left> Solar energy converted to thermal paper . The United States has developed a paper that converts solar energy into heat, which can function as a solar collector. Foods packaged in such insulated paper are placed in a place exposed to sunlight, and the food in the package is heated. Only when the package is opened, heat can be dissipated.

Normal align=left> Heat-sealing wrapping paper . Heat-sealing packaging paper has heat-sealing property, air permeability, and has the characteristics of oil resistance, water resistance, safety and harmlessness. In order to make the packaging paper heat-sealable, the surface of the heat-sealable resin paper is covered with a coating or bonded with polyethylene to make it have a heat-sealability, and no secondary processing is necessary to obtain air permeability, and its air permeability can be The user requests control. With this kind of breathable packaged food, it can be heated by electromagnetic waves and there is no steam in the package, which can keep the food surface fresh. Because of its characteristics, the heat-sealing wrapper can be used as a packaging material for frozen foods heated by electromagnetic waves, and it has been used for packaging hamburgers.

Normal align=left > Insulation wrapper . The function that this kind of paper should have is to maintain the freshness, freshness, and freshness of cooked foods, so that people can ask for convenience when they are in different places. The site adapts to the fast-paced needs of people today. The principle of this insulation paper is to convert light energy into heat like a solar collector. Usually, people only need to put this special paper on the place where the sun can shine, and the space surrounded by the paper will be constantly replenished with heat, so that the food in the paper will maintain a certain degree of heat, so that people can enjoy the taste of heat at any time.
