Today, as people's awareness of environmental health is enhanced, the requirements for packaging are getting higher and higher. Paper packaging adapts to the development needs of green packaging and also solves the problem of environmental pollution caused by packaging waste. Can undertake a variety of food packaging tasks, there will be better and faster development in the future. At present, food packaging around the world has a good momentum of continuous growth. Paper packaging is moving in several directions of versatility:
Moisture-proof: The waterproof material is dipped on the surface of the paper to form a film attached to one or both sides of the paper, so that the food packaging paper has moisture-proof properties. This paper has good printing, folding, bonding and other characteristics, and can be used like ordinary paper.
Preservation: After the pulp is chemically treated and a selective resin is added, the paper can be used to preserve the baked goods.
Temperature sensing: Adding artificial fibers that change color with temperature changes in the pulp, indicating the ambient temperature according to the color change of the wrapping paper, and effectively storing the food according to the color change of the food packaging bag.
Visible: After special surface treatment, after the surface of the paper is wetted, the paper changes from opaque to transparent. Consumers can see the food in the bag without unpacking, and in the dry state, it can be protected from light. effect.
Edible: Extracting edible wrappers from vegetables and shells, which is convenient for consumers and avoids environmental pollution caused by packaging waste.
Sterilization and anti-corrosion: Injecting sterilizing or anti-corrosion materials into the pulp, so that the paper packaging has the function of preventing bacteria from invading and delaying the deterioration of the food.
Other functional food wrappers, as well as various special materials such as water, oil, acid and deodorant.
In recent years, paper and paper containers have played a very important role in the packaging industry. In China, paper packaging materials account for about 40% of the total packaging materials. From the perspective of development trends, the amount of paper packaging will increase. According to the forecast of the relevant planning department, it will reach 27 million tons from 2006 to 2010 and 36 million tons from 2011 to 2015. At the same time, the implementation of the “plastic limit order” further promoted the market demand for paper packaging.
