In the modern packaging industry system, paper and paper containers play a very important role. In China, paper packaging materials account for about 40% of the total packaging materials. From the development trend, the consumption of paper packaging will increase. The reason why paper packaging materials are in the forefront of packaging is because they have a series of unique advantages, such as good processing performance, good printing performance, good mechanical properties, easy to compound processing, good health safety, wide source of raw materials, easy to form large quantities of production, variety and low cost. Light weight, easy to transport, waste can be recycled, and plastic packaging material is an important symbol of modern technology development, rich source of raw materials, low cost, excellent performance, become the world's fastest, large amount of packaging materials in the world in the past 40 years. However, the plastic packaging materials used in food packaging have obvious shortcomings, there are some problems in health safety and the pollution of packaging waste to the environment.

 

Paper packaging will replace plastic packaging in the future food field

 

Information shows that the amount of plastic used in food packaging accounts for 1/4 of the total output of plastic, and it can be said that when the plastic for food packaging appears, there is garbage. In supermarkets and shopping malls, many food packages are made of plastic. The plastic inflatable packaging of expanded food can prevent moisture, prevent oxidation, protect the fragrance, prevent sunlight from being exposed, prevent from being squeezed, but the large packing is a great waste on the resources; and the packaging of instant noodles is far more than the packing of paper bowl (or bucket), and the sale price of the bowl or barrel of instant noodles is generally high. The sale price of the same quality bag of instant noodles is 1/3, but because of this kind of packing way is convenient to eat, especially when traveling, it can be eaten directly after opening the lid after opening the lid, without any other container, so it is very popular with consumers.

 

With the improvement of environmental protection requirements, it is necessary for consumers to eliminate backward packaging. The improvement of plastic materials is also an urgent matter. Food in the market segments can be packed with paper as much as possible, reducing the waste of plastics and the pollution of the environment. This is also for the benefit of future generations.
