The "new darling" in wrapping paper

In order to meet the needs of the development of the packaging industry, in recent years, some new packaging papers have been developed in the paper industry. Here are just three examples:
This summer, Japan’s National Paper Corporation launched a new paper called “Feather Functional Paper.” This paper has good water resistance, water resistance, oil absorption, hygroscopicity, etc. It can be used to package a variety of goods, and can also be printed with a trademark logo. Particularly valuable is that its waste paper is still recyclable and recyclable and meets the requirements of environmental protection, and is therefore well received by users. The paper is made from chicken or duck feathers collected from the market or slaughterhouses, disinfected, cleaned, and crushed by a machine. The powdered feathers are then applied to the paper and coated with feather fibres. Specialty paper. According to reports, the company has already obtained a patent in Japan, and it will
South Korea and Taiwan filed patent applications.
In the spring of 1998, a new product called "heated paper" appeared on the Japanese market. It was alleged that the raw materials used were not ordinary plant fibers but glass fibers and carbon fibers. This kind of paper is more difficult to manufacture. It must control the orientation of the fibers when the paper sheet is formed according to the requirements of the design. The "circuit network" in the paper must be ordered vertically and horizontally, and the "current channel" ring should be connected. Otherwise, it is not easy to produce. Heat effect. The most important difference between heat-generating paper and plain paper is that the former cannot be cut arbitrarily. The 12-volt dry battery must be connected to the “end” of the finished product to generate heat. The application of this kind of paper is very attractive. For example, wrapping bread, sausages, cooked foods, and the like using heat-generating paper can make the food hot and delicious after being energized, and has the effect of replacing the microwave oven. However, the current price of this type of paper is relatively high and application is limited.
At the end of the fall of 1996, Japan developed a deodorizing paper (also known as deodorizing paper), which is a new type of special clean and hygienic paper. Deodorization refers to the elimination or reduction of unclean, unpleasant odors contained in the air within a limited space. Therefore, for this kind of removal, the requirements for stinking paper should have the following "three properties": sorptiveness, barrier properties, and decomposability. In general, the effect of deodorization has the greatest relationship with the sorbency of the paper, that is, the more malodorous gas that is absorbed, the better its function. However, if there is no definite barrier to "lock up" the bad gas, it is not ideal. Of course, whether or not the gas can be decomposed depends on the ingredients added to the paper (ordinary deodorant paper does not contain expensive decomposers). This kind of paper is processed on the base paper using "deodorant paint". Deodorizing paper is used in a wide range of applications and can be processed into liners or paper strips in packaging boxes to absorb a variety of unpleasant odors.
