Food packaging and paper plastic competition in th

Competition between food packaging and paper and plastic in the market at present, there are quite a lot of food packaging types in the market. In terms 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

paper and paper containers play a very important role in the conventional testing: ring stiffness test, ring flexibility test, creep ratio test in the modern packaging industry system. 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 working performance, excellent printing performance, certain mechanical properties, easy composite processing, good health and safety, wide sources of raw materials, easy to form mass production, diverse varieties, low cost, light weight, and convenient transportation, Waste can be recycled; The use of plastics as packaging materials is an important symbol of the development of modern technology. With rich sources of raw materials, low cost, excellent performance and innovative green metallurgy, it has become the fastest-growing and huge amount of packaging materials 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 packaged in paper, so as to reduce the waste of plastic and environmental pollution, which is also beneficial to future generations
