For a long time, plastic products have been widely used in food packaging. Because plastic is extremely difficult to degrade naturally, it causes serious environmental pollution. Therefore, some developed countries have partially restricted the use of plastic packaging. To this end, the development of food packaging paper has become a consensus in the food and packaging industry. According to the different perspectives of food packaging paper, new food packaging paper can be divided into the following categories.
Waterproof dewatering wrapping paper
This kind of packaging paper called PS selects a semi-permeable membrane that can only pass water as the surface material, and a high osmotic pressure substance and a polymer water-absorbing agent are placed on the inside. The packaging paper will not destroy the food tissue cells, at the same time, it can inhibit the activity of mold, prevent protein decomposition, reduce microbial reproduction, and achieve the effects of maintaining food freshness, concentration, umami components, and improving toughness.
Absorbent paper
The biggest feature of the absorbent paper is its strong water absorption capacity. It can maintain the water absorption of 10 times its own weight, and it is safe and harmless. There is a significant difference in the water absorption capacity and water retention capacity of the water-absorbing functional paper and the non-woven fabric, and the water-absorbing functional paper is obviously dominant. This is because the non-woven fabric can only retain moisture in the pores between the raw material fibers, and the absorbent paper not only has the above capabilities, but also the fibers themselves can absorb water. After the absorbent paper absorbs water, it becomes very soft. Due to the following characteristics, the absorbent paper can be used as a film (sheet) for absorbing condensation on ham, sausages, etc., a film (sheet) for absorbing dripping of fresh food, and a film for cosmetics and sanitary materials.
Acid-free waterproof file paper
The new waterproof packaging paper and paperboard (acid-free waterproof archival paper) independently developed by Hunan Changde Cigarette Factory Jin Furong (Special) Paper Co., Ltd. successfully filled the domestic gap. The company has started projects since 1996 and has invested a total of 3.15 million yuan to develop new waterproof packaging paper. According to relevant experts, the new waterproof packaging paper and cardboard have a wide range of applications.
Screen wet cardboard
The Minnesota Libery Paper Co., Ltd. has developed M-Guard screen wet paperboard, which is similar to corrugated paperboard and similar to common liner paperboard. It can be printed, recycled, and beaten for processing. The wettability of the cardboard has a visual effect. This kind of screen damping performance is caused by the internal chemical bonding performance during the papermaking process, without any conversion, which can save time. The paperboard achieves good screen damping performance through its inherent absorption
Water-resistant processing paper
Water-resistant processed paper has good water resistance and breathability, because the penetration rate is higher than other materials, its surface strength and interlayer strength are high, it has antibacterial properties, and it can absorb ammonia gas and so on. These characteristics are not obtained by additive resins and chemicals, but by the pulp of raw materials, so they are safe and harmless. Because MWS has the above characteristics, it can be expected to be used in food packaging materials, dew condensation films (sheets) and other fields. At present, MWS has been applied to the vacuum packaging of wine trough stained foods. It is compounded with other materials and used as a packaging paper for semi-products with high moisture content. It fully exerts its advantages of mildew resistance, water absorption and water resistance. Thermal energy protein coated packaging paper The company has also developed a protein-coated packaging paper, which is made by dissolving protein. The protein is used as a coating on the paper, and the packaging paper film is made by a special process, which can withstand a certain temperature, prevent corrosion, non-toxic, facilitate food processing, and do not pollute the environment.
Paper converted from solar energy to heat
The United States has developed a paper that can convert solar energy into thermal energy, which can function as a solar collector. Use this kind of insulation paper to package food and put it in the place where the sun shines, the food in the package will be heated. Only when the package is opened, the heat can be dissipated
Heat-sealable wrapping paper
Heat-sealable packaging paper has the characteristics of heat-sealability, air permeability, good oil resistance and water resistance, and is safe and harmless.
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 heat-sealable. No secondary processing is required to obtain air permeability. Its air permeability can be adjusted according to the user Ask for control. Food packaged with this kind of breathable packaging paper can be heated by electronic waves, and there is no steam in the package, which can keep the surface of the food fresh. Since it has the following characteristics, the heat-sealable packaging paper can be expected as a packaging material for frozen food heated by electronic waves, and it has been used to package hamburgers.
Insulation wrapping paper
The function of this kind of paper is to keep the cooked food packed in fragrant, fresh, and hot, and it is convenient for people to eat on different occasions, in order to meet the needs of the fast-paced life of people today. The principle of this insulation paper is like a solar collector, which can convert light energy into heat energy. Usually people only need to put this special paper in a place where the sun can shine, and the space surrounded by the paper will be continuously replenished with heat, so that the food in the paper keeps a certain degree of heat, so that people can eat delicious and delicious Cuisine.
Fruit and vegetable pomace paper
Japan's Gaoqi Paper Co., Ltd. uses waste apple pomace from the food industry to produce pomace paper. The method is simple. It removes the seeds in the pomace, pounds it into pulp, and can be made by adding an appropriate amount of wood fiber. It is easy to decompose, it can be burned or composted, and it can also be recycled to make paper, which is not easy to pollute the environment.
Okara paper
A research institute in Japan used new technology to make okara as a raw material to make a kind of wrapping paper that is soluble in heat and has certain nutritional value. The packaging paper is suitable for the packaging of fast food noodle seasoning, and can be eaten together when eating.
Carrot wrapping paper
The carrot paper developed by the United Kingdom uses carrots as the base material, adding appropriate thickeners, plasticizers, and water-resistant agents, and uses carrots' natural color to make inexpensive and high-quality edible colored vegetable paper. This product can be used for individual (inner) packaging of boxed food or directly eaten as a convenience food, which can not only reduce environmental pollution, but also enhance the beauty of food and increase consumers' appetite and appetite. Carrot paper is an edible colored paper.
Color-changing straw is a very interesting straw, its color will change with the temperature, and it is more personalized than ordinary straw with a single color.
Our color-changing straw is purple at normal temperature through a unique process. It turns pink when exposed to high temperature such as hot water. It is very creative.
