Special function food wrapping adds bright colors to life

With the rapid development of science and technology, commodity production is changing with each passing day, but it also brings some unfavorable factors, more prominent health and environmental protection issues. Therefore, people have stepped up the development and transformation of the original product to ensure human health and environmental protection concepts. For example, in food packaging materials, there have been some special novel packaging materials in recent years.

Special function food packaging paper 1) Okara wrapping paper. A Japanese research institute has used high-tech to develop edible wrapping paper made from bean dregs as a raw material. This wrapping paper is more suitable for instant noodles and seasonings. It does not have to be torn apart when it is eaten, as long as it dissolves with hot water. , can be eaten with the packaging, have a certain nutritional value.

2) Long-lasting mildew-proof paper. The mildew-proof wrapping paper, which is usually used for packaging of foods, agricultural products, fruits, daily sanitary articles, etc., is a kind of agent for preventing the growth of the mold caused by the growth of the mold during the manufacturing process of the paper. It is packaged with the articles at room temperature and can form an antibacterial atmosphere around the articles, which can destroy the existence of molds harmful to human health without affecting human health. It is non-toxic, odorless, and non-corrosive so as to achieve anti-mildew purposes. It is a new breakthrough in the use of chemical antibacterial agents in recent years. The long-term anti-mildew paper produced by a company in Japan is a new type of wrapping paper that can prevent food moldy and spoilage for a long time and does not damage the flavor of food. The paper is an aqueous solution in which a special monoglyceride is fused with a compound therein and dissolved as an active ingredient in water and ethanol, and is then sprayed or infiltrated on paper and dried by heating.

3) Self-adhesive wrapping paper. Korea made a kind of self-adhesive wrapping paper. The outer layer is kraft paper. The inner layer is a special foaming material. It has elasticity and excellent corrosion resistance, which can ensure that the surface of the package is not frayed. Because of its inherent viscosity, no ropes and straps are required for packaging. The wrapping paper automatically loses its stickiness upon unsealing, and therefore it also has the effect of preventing the person from being unsealed.

4) Fruit lap paper. Singapore develops and produces a plastic wrap that has antibacterial and antiseptic properties. Using this kind of paper to store the apple, after a few years of opening, the fruit is still full and the background is green, like a new pick. Another fresh-keeping paper can keep fresh citrus for 3 months, and litchi can also keep fresh for more than 30 days. In addition, Japan's Showa Chemical Co., Ltd. developed fruit wrap, which uses a mineral concentrate made of phosphoric acid as a raw material to infiltrate absorbent paper bags. Use this kind of paper container to pack vegetables and fruits. During transportation, vegetables and fruits can be supplied with nutrients from mineral concentrates. Practice has proved that calcium phosphate can absorb ethylene and carbon dioxide gas, inhibit the decomposition of chlorophyll, play a preservation effect.

5) Corrosion preservation packaging paper. Orenson Paper Co., Ltd. of Sweden introduced highly breathable food packaging paper. Its inner and outer layers have a thin layer of fluorine resin, not water, no oil, wrapping the food can make the same temperature inside and outside, into the refrigerator can better maintain the original flavor of food, fresh as ever. A Japanese company uses a paper immersed in ethanol solution containing 2% succinic acid, 33% sodium succinate and 0.07% sorbic acid, and then dried to make paper for food packaging. The food used for packaging can be stored at 38 degrees. The week is not bad.

6) Acrylic synthetic paper. Japanese experts made a synthetic paper using propylene from petroleum gas as raw material. This paper is strong, not easy to break, has a smooth surface, no wrinkles, no moisture, and no discoloration. This kind of paper is lighter than ordinary paper and is not easily stained. It is a good material for printing, writing and food packaging.

7) Protein-coated wrapper. It is a wrapping paper made by a Japanese company that has dissolved protein and made it through a special process. The protein-coated wrap film coated with protein as a coating on the paper can withstand a certain temperature, prevent water eroding, non-toxic, convenient for food processing, and does not pollute the environment.

8) Insect film or protein coated wrapping paper. The wrapper or container is a film wrapper or a packaging container obtained by dissolving shellac or protein and having a special process. This packaging is non-toxic, easy to handle, and can withstand the erosion of certain temperatures and moisture.

9) Biological glue coated wrapping paper. The wrapping paper is a water-resistant and oil-resistant coated wrapper obtained by using a special starch glue and bone glue together with a certain amount of additives and applying the obtained glue to the paper surface. Packaging containers made from this paper can be used for fast food or food packaging that requires a certain temperature and moisture.

10) Starch and de-acetate chitosan wrap. It is a type of edible wrapping paper that Japan has recently developed. Starch packaging paper uses starch as a raw material and is processed by adding other edible substances. De-acetate chitosan wrapper is processed from de-acetate chitin as raw material. These two types of wrapping paper are suitable for instant noodles, seasonings, etc. The package can be directly put into a pan for cooking and eating.
