In recent years, researchers have stepped up the development of packaging paper products, and a number of unique packaging paper products have emerged.
The most important feature of the water-absorbing functional paper is that it has strong water-absorption capacity. It can maintain the water absorption capacity of the material 10 times its weight, and it 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 dominant.
This is because non-woven fabrics can only retain moisture in the pores between the fibers of the raw materials, and the paper not only has the above capabilities, but also the fibers themselves can absorb water, and the water-absorbing functional papers become very soft after absorbing water.
Due to these characteristics, the water absorbing functional paper can be used as a film (sheet) for absorbing condensation such as ham and sausage, a film (sheet) for absorbing fresh food drip, and a film package for cosmetics and sanitary materials.
Protein coated paper Japan Foods Co., Ltd. has developed a protein-coated wrapper, which is a wrapper film coated with protein as a coating on top of a special process and can withstand a certain temperature to prevent erosion and non-toxicity. , convenient food processing, does not pollute the environment.
Water-Resistant Wrapping Paper This type of wrapper has good water resistance and air permeability, because its penetration rate is higher than that of other materials, its surface strength and interlayer strength are high, it has antibacterial properties, and it can also absorb ammonia.
These features are not obtained by additives, resins, and chemicals and are therefore safe and harmless. Because of these characteristics, MWS can be applied to food packaging materials, condensation water-absorbing films (sheets) and other fields.
At present, MWS has been applied to the vacuum packaging of distiller's grain-sweet foods, and is compounded with other materials. As a packaging paper for multi-moisture semi-finished foods, MWS fully exerts its advantages of mildew proof, water absorption and water resistance.
Heat-sealing wrapping paper The wrapping paper has the characteristics of heat-sealing, ventilation, 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 coated or adhered with polyethylene to make it heat-sealable and no secondary processing is necessary to obtain air permeability.
Foods packaged in such breathable wrappers can be heated by electromagnetic waves, and there is no steam in the package, which keeps the food surface cool. Because of its characteristics, the heat-sealing wrapper can be used as a packaging material for frozen foods heated by electromagnetic waves, and it is currently used for packaging hamburgers and the like.
Carton wrapper This type of wrapper developed in the United Kingdom uses carrots as a base material, adds appropriate thickeners, plasticizers, and water repellents, and uses the natural color of carrots to make an inexpensive edible vegetable dish.
This kind of vegetable paper can be used as an individual (inner) package 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 the appetite of consumers. Carrot paper is an edible color paper, with strong flexibility and a certain degree of waterproof, but also has a packaging function and food function.
The function of this type of paper, which is introduced in the foreign market, is to maintain the freshness, freshness and heat of cooked foods for people to eat on different occasions. 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 sunlight can shine, and the space surrounded by the paper will be continuously replenished with heat, so that the food in the paper will maintain a certain degree of heat.
