For a long time, food packaging box http://a large number of plastic products, due to the extremely difficult natural degradation of plastic, causing 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 angles of food packaging paper, new food packaging paper can be divided into the following categories.
Waterproof dewatering wrapper This type of wrapper called PS is made of a semipermeable membrane that can only pass through water as a surface material, and a high osmotic pressure substance and a polymeric water absorbing agent on the inside. The wrapping paper does not destroy the cells of the food tissue, and at the same time inhibits the activity of the mold, prevents the decomposition of the protein, reduces the proliferation of the microorganisms, and achieves the effects of maintaining the freshness, concentration, umami composition and toughness of the food.
Water absorption function Paper water absorption function paper is characterized by strong water absorption capacity, which can maintain the water absorption capacity of the material 10 times its own weight, and is safe and harmless. There is a significant difference between the water absorption capacity and the water retention capacity of the water absorbing functional paper and the non-woven fabric, and the water absorbing functional paper is obviously superior. This is because the nonwoven fabric can only retain moisture in the pores between the raw material fibers, and the water-absorbing functional paper not only has the above capabilities, but also the fibers themselves can absorb water. The water-absorbing function paper becomes very soft after it absorbs water. The water absorbing functional paper can be used as a film (sheet) for absorbing condensed ham, sausage, etc., a film (sheet) for absorbing fresh food, and a film for cosmetics and sanitary materials.
The acid-free waterproof archive paper was successfully developed by the Hunan Changde Cigarette Factory Jin Furong (Special) Paper Co., Ltd., a new type of waterproof packaging paper and cardboard (acid-free waterproof archive paper), which successfully filled the domestic gap. The company has been in charge 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 are widely used.
Screen Wet Paperboard Libery Paper Co., Ltd. of Minnesota, USA has developed M-Guard screen wet paperboard, which is similar to corrugated board. It is also similar to commonly used linerboard, which can be printed, recycled and re-pulped. The board's wet performance has a visual effect. This screen wetness performance is caused by the internal chemical bonding property during the paperboard manufacturing process, and no conversion is required, which can save time.
The water-resistant paper resistant to water-processed paper has good water resistance and air permeability, because the penetration rate is higher than other materials, its surface strength and interlayer strength are high, it is antibacterial, and it can absorb ammonia gas and the like. These features are not obtained by additive resins and chemicals, but by the pulp of the raw materials, so they are safe and harmless. Since MWS has the above characteristics, it can be expected to be applied to food packaging materials, dew condensation water absorption films (sheets), and other fields. At present, MWS has been applied to the vacuum packaging of wine-growing foods, and is compounded with other materials. As a packaging paper for multi-moisture semi-finished foods, it fully utilizes its advantages of mildew resistance, water absorption and water resistance. Thermal energy protein coated packaging paper Japanese food The company has also developed a protein-coated wrapper, which is a wrapper made by dissolving proteins. The protein is applied as a coating on the paper, and the packaging paper film is formed by a special process, which can withstand a certain temperature, prevent erosion, is non-toxic, facilitates food processing, and does not pollute the environment.
Insulation wrapping paper This paper has the function of keeping the delicatessen, fresh and hot after packaging, so that people can easily eat it in different occasions to meet the fast-paced needs of today's people. The principle of this insulation paper is to convert light energy into heat energy like a solar collector. Usually people only need to put this special paper in the place where the sun can shine. The space surrounded by the paper will be replenished with heat, so that the food in the paper will maintain a certain heat, so that people can enjoy the hot and delicious at any time. The cuisine.
