[Chinese Packaging Network News] At present, the packaging industry, all kinds of materials, all kinds of performance of the paper are all supernatural, how much do you know about these papers? Let's take a brief look at some of the more novel types of paper in the world.
First, long-term anti-mold paper
A new type of wrapping paper produced by a company in Japan that can prevent moldy deterioration of foods for a long time and does not damage food flavors. The paper is a water soluble solution of water and ethanol dissolved as an active ingredient after the special monoglyceride is fused with the compound, and then sprayed or infiltrated on the paper and finally dried by heating. It can be used to package a variety of foods.
Second, fruit fresh paper
In order to maintain the freshness of fruit, Singapore developed and produced a fresh-keeping wrapping paper that has antibacterial and bactericidal properties. The apple was stored on this type of paper and opened after six months. The fruit was still full. Another fresh-keeping paper can keep fresh citrus for 3 months, and litchi can also keep fresh for 30 days.
Third, environmental protection type environmental protection paper roll
A British company developed and successfully developed a green paper roll that can replace foam plastics. There are many small cracks on the top, occupying a small space. When the paper roll is unrolled, it becomes a three-dimensional honeycomb with an area 10 times the original. It can act as a cushioning cushion for filling and holding packaged goods. The paper roll is made of recycled fiber and can be recycled for reuse; when it is discarded, it can be biodegraded.
Fourth, PLMEX food packaging paper
In the European and American markets, there is a brand new PLMEX food special packaging paper, which is 100% pure pulp, does not contain fluorescent agents and chemical substances that harm the human body. It is waterproof, oil-repellent, anti-sticky, and heat-resistant (or resistant to 200°C. 250 °C high temperature) features. Easy to use, simple to clean, safe and hygienic, and in line with US PDA and German PGA food hygiene standards. This food special paper can be recycled after cleansing with clean water after use, and can be used repeatedly 50 times. This type of food paper is rolled and pressed into a variety of paper cup shapes. Whether used for steaming, baking or microwave heating, it does not deform or fade.
Fifth, artificial peel paper
An artificial peel paper that can be recycled is favored after its introduction in foreign markets. This artificial peel paper is made of special materials. It is completed on the factory's automatic line with the production of food. It is a tight transparent pouch or transparent shaped ring. It is tough and flexible, and can extend the shelf life of foods. When eating, it only peels the artificial peel paper.
Sixth, paper cans
At present, the annual consumption of aluminum cans in China is between 6 billion and 7 billion, raw materials need to be imported in large quantities, and the price is expensive. Together with environmental pollution and other factors, the country has no longer approved the new aluminum can production line. The ability to find new packaging containers that replace aluminum cans has become a constant concern in the industry. The birth of paper cans overcomes the shortcomings of aluminum cans and has broad prospects for development. The construction of an aluminum can production line requires at least 17 million yuan, while the paper can production line only needs 2 million yuan; the minimum batch volume of aluminum cans is 20 million, and the economic volume of paper cans is more than 20,000. Paper cans can be used in paint, chemical, food, medicine and other packaging, but also used to produce paper boxes, paper cups, paper drums and other products. Experts estimate that the annual demand for Chinese cans will gradually reach 15 billion, and its excellent characteristics will inject new vitality into the Chinese packaging industry.
Seven, 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 with dirt. It is a good material for printing, writing and food packaging.
Eight, foam paper
The German company PSP has developed a new process for the production of foamed paper. The packaging materials produced with it can replace foamed plastics. The foam paper uses old books scrap paper and flour as raw materials. The old newspapers are first cut into shreds, then ground into fibrous pulp, and mixed with flour in a ratio of 2-1. The mixed pulp stock Into the extrusion press into cylindrical particles. During the extrusion process, the raw material is subjected to steam as a foam paper. Using this type of foamed paper pellet as raw material, various shapes of plastic packaging can be produced according to different needs. Foam paper can be molded once, without chemical additives, and can be recycled after use.
Nine, rigid light packaging paper
A Finnish company successfully developed a hard, lightweight wrapping paper. This kind of wrapper is 10%~20% lighter than ordinary paperboard. Besides having odorless, organic survival properties, it also has heat resistance and the same printing property as pure pulp board, especially suitable for packaging chocolate, ice cream, frozen food, etc. For a variety of flavor-type packaging and manufacturing snack boxes.
Ten, 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 packaging 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.
