At present, there are many kinds of food packaging in the market. From the perspective of packaging materials, there are paper packaging, plastic packaging, metal packaging and glass packaging. Now plastic packaging has a large market share, but its production only pays attention to the safety and health of food, rarely considers environmental issues, and the pollution caused is also obvious to all. So, will the future food packaging be dominated by paper packaging or plastic packaging
in the modern packaging industry system, paper and paper containers occupy a very important position. In China, paper packaging materials account for about 40% of the total packaging materials. From the perspective of development trend, the consumption of paper packaging will be increasing. The reason why paper packaging materials take the lead in the packaging field is that they have a series of unique advantages, such as good processing performance, excellent printing performance, certain mechanical properties, easy composite processing, good health and safety, wide sources of raw materials, easy formation. Through the control of the cold rolling process of TC6 plate, researchers have achieved mass production, diverse varieties, low cost, light weight, and easy transportation, The key of waste is to use the correct world outlook, outlook on life and values to guide their choice of recyclability; The use of plastic as packaging material is an important symbol of the development of modern technology. With rich sources of raw materials, low cost and excellent performance, it has become the fastest-growing and huge amount of packaging material in the world in recent 40 years. However, plastic packaging materials used in food packaging have obvious shortcomings, and there are some health and safety problems and environmental pollution problems caused by packaging waste
some data show that the amount of plastic used for food packaging accounts for 1/4 of the total plastic output. It can be said that as soon as plastic used for food packaging appears, garbage will be generated. In supermarkets and shopping malls, many food packages are made of plastic. The plastic inflatable packaging of puffed food can prevent moisture, oxidation, fragrance, sunlight and extrusion, but such a large packaging is a great waste of resources; There is also the packaging of instant noodles. Plastic packaging is far more than the packaging of paper bowls (or barrels). The sales price of bowls or barrels of instant noodles in the market is generally higher than 1/3 of the sales price of packaged instant noodles of the same quality. However, because this packaging method is convenient to eat, especially when traveling, it can be eaten directly by boiling bubbles after opening the cover, and there is no need to bring other containers, 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 a top priority. The food in the market segment can be used. The industry is also looking forward to welcoming the consultation. Green building materials have achieved double breakthroughs in technology and policy support. Paper packaging should be used as much as possible to reduce the waste of plastic and environmental pollution, which is also for the benefit of future generations
