Green Packaging Becomes Development Trend Food Packaging Towards "Paper Age"
With the development of packaging industry, as long as the products are sold on the market, there will be packaging, which brings tremendous pressure to the environment. Under the influence of environmental awareness, Green has become the development direction of packaging industry. At the same time, food safety incidents also promote the packaging industry to develop in a green direction. In recent years, baking food packaging has begun to move towards the era of paper packaging.
The rapid development of China's food industry has provided a broad space for the development of paper packaging. It is expected that circular economy will become the main mode of packaging industry development in the future, recycling and utilization of waste packaging resources will realize industrialization, green packaging materials will be vigorously developed and developed, and packaging infrastructure industry will also accelerate development.
Since the 1980s, "green food", "green clothing", "green refrigerator" and "green car" have set off a huge wave of green in the world. The average annual consumption of packaging materials in foreign countries is over 100 kg, 50 kg in the United States, 200 kg in Japan, 90 kg in Germany, 80 kg in CIS and 30 kg in China. Compared with China, the average annual consumption of packaging materials in China is relatively low, but the population of China is more than 1.3 billion, so the annual consumption of packaging materials is quite large. Therefore, green environmental protection has become the inevitable development direction of packaging industry.
Green packaging can also be referred to as environmental friendly packaging (Environmental Friendly Package), which is harmless to the ecological environment and human health, can be reused and regenerated, in line with sustainable development of packaging. Reduce, Reuse, Recycle and Degradable are the accepted 3R and 1D principles for developing green packaging in the 21st century. In the view of PPzhan, green packaging should be understood as completely safe and pollution-free in the life cycle. Paper packaging has undoubtedly become the most environmentally friendly packaging material.
The raw material of paper is mainly natural plant fibers, which will decay quickly in nature, will not pollute the environment, and can also be recycled for paper making. Therefore, many large international companies use recyclable paper to produce annual reports and publicity materials, and use recycled paper to make letterpads and stationery to reflect their green purpose of paying attention to the environment, at the same time, they have established a good corporate image. Paper materials are also used for pulp casting parts, composite materials, building materials and other purposes. Besides the advantages of light weight, low price and shock proof, pulp moulded products have good air permeability, which is conducive to the freshness preservation of fresh articles. In the international circulation of commodities, pulp moulded products are widely used in the turnover packaging of fragile, fragile and extruded articles such as eggs, fruits and glass products.
The world of packaging boxes in the future is made of paper. The whole world calls for green packaging and cherishing our homeland. Paper technology will be widely used in packaging industry. Green packaging will become the main trend of baking food packaging industry in the future. But paper instead of wood, paper instead of plastic, paper instead of glass, paper instead of metal, has become the consensus of sustainable development. Paper materials have more renewable natural raw materials and more environmentally friendly recycling, fully demonstrating the development potential of paper materials.
Paper packaging based on paper and cardboard has the advantages of low cost, resource saving, easy mechanical processing, environmental protection, pollution-free, easy recovery and recycling. Whether it is used for transport packaging cartons, or for the sale of product packaging cartons, paper bags, are the first choice of paper materials. With the development of papermaking technology and the enhancement of environmental protection consciousness, the traditional single paper material is developing towards the direction of compound diversification. Composite paper, functional paper and non-polluting vegetable fiber paper have been developed continuously. The function and applicability of paper materials are not the same as before. Not only widely used in pharmaceuticals, cultural and educational supplies, hardware products, daily necessities, cigarettes, food, crafts, cosmetics, small household appliances, etc. It also replaces the packaging of other materials.
Under the trend of homogenization of all kinds of commodities, packaging has become the third absolute selling factor and an important factor to establish brand image after the quality of commodities and after-sales service. Packaging from the original function of commodity protection and convenient use, to increase the value of commodities, build brand, promote the development of sales. Packaging design has become an important part of commodity marketing plan. Paper packaging is the first of the four major packaging. With the continuous development of paper materials and processing technology, the shape is becoming more diverse and creative.
Appropriate and practical structure and novel appearance have become important factors for businesses to enhance product and brand market competition. Excellent paper packaging will break through the limitations of paper packaging in the past, give full play to the advantages of good physical properties and printing applicability of paper materials, fully display the characteristics of paper packaging, such as capacity, protection, convenience, display, aesthetics, economic applicability, increase the added value of products and improve sales. Ability.
From production to recycling, packaging paper includes processing technology, storage and transportation environment, marketing display, consumption and utilization, and recycling. The technical requirements and functional requirements of each link are the main basis of packaging paper design. These key factors of paper forming are interrelated and restrictive, and need deep investigation by designers. Recently, folding cartons need to be prepared for the design of similar systems. Suitable for industrial production of folding program design, cutting, indentation, grooving, one-time forming, unfolding, folding, display, portable and easy to use.
Paper material selection is also the key to create excellent packaging paper. Current papermaking technology is quite advanced. Paper material has changed from traditional single to diversified varieties and functions.
