Experts predict that the production and marketing of green products in the 21st century will become the mainstream of world marketing. While plastic products bring convenience to mankind, they also produce a large amount of "white pollution", which has become a major social problem in the world today.
Fortunately, mankind has begun to challenge the old environmental path of "pollution first and treatment later", developing green and environmentally friendly products, and eliminating white pollution has become the common sense of all mankind. At present, from an international perspective, it is difficult for any plastic product packaging to enter the international market. Many European and American countries have banned the use of plastic packaging and foam plastic tableware.
Looking at the domestic situation, governments at all levels, such as Hangzhou, Fuzhou, Wuhan, Guangzhou, Chengdu, Xiamen, Shantou, Changchun and other cities, as well as the Ministry of Railways and the Ministry of Transport, have also issued decrees to ban non-degradable foams. Plastic quick cutlery.
Currently, a global revolution in plastic packaging products is gradually emerging. Green packaging of "paper instead of plastic" has become a development trend in the world's packaging industry. It is under this general trend that a new type of green tableware, pulp molded tableware, was born.
Pulp molded fast food tableware is a new technology and new product pioneered in my country. It is a replacement product of the foam plastic fast food tableware currently popular in the domestic market. Pulp molded fast food is made of pure plant fiber slurry as the main raw material and is molded using advanced technology and scientific processes. This process changes the traditional paper box folding and molding method, and uses the sugarcane pulp molding method to overcome the weakness of plant fiber's poor strength. In terms of waterproofing and oil-proofing, the spraying method used in Western countries has also been changed. Instead, waterproofing additives are placed in the slurrying process stage, allowing the additives to be adsorbed on the plant fibers and then hot-pressed to form, reducing the spraying process and increasing product strength. .
Compared with the paper tableware technology in Western countries, foreign countries use wood pulp as raw material, and the cold-pressed cardboard tableware is only suitable for holding Western-style dry food, and does not have the waterproof and waterproof properties to hold hot food and soup. Oil-proof, heat-resistant and other properties are not suitable for the dietary characteristics of Chinese people. The fast food tableware produced by the pulp molding process can adapt to the eating habits of the Chinese people, and has the advantages of being non-toxic, tasteless, waterproof and oil-repellent, compressive and tensile resistant, and convenient and applicable. After testing by the relevant health and quality inspection departments, various indicators All meet the national food packaging hygiene standards.
The production process formula is mature and the equipment operates stably. The daily output of each production line is around 50,000 to 100,000 pieces. The entire production process is pollution-free. In order not to damage forest resources, the raw materials of this product do not use wood pulp but mainly straw pulp. The main raw materials include reeds, straw, wheat straw, sugarcane bagasse, etc. In northern and southern my country, reed and sugarcane fiber pulp can be used as raw materials according to local conditions. In this way, products originate from nature and return to nature, and waste can be recycled and reused. Even if it is not recycled, this kind of plant fiber can self-degrade in a short period of time, nourishing fields and fertile soil, which is beneficial to ecological balance. Fundamentally solve the social hazard of "white pollution".
At present, many domestic enterprises are investing in the construction of pulp molded tableware production bases, actively responding to the government's call, taking science and technology as the guide, taking environmental protection as their own responsibility, developing environmentally friendly products, controlling white pollution, and affecting the economy and society. The benefits are significant.
Today, among the environmentally friendly products to control white pollution, there is a kind of degradable plastic, namely photodegradable plastic and biodegradable plastic. However, the difference between degradable plastics and non-degradable plastics is nothing more than a change in the geometric shape of the object, which cannot fundamentally solve the problem of white pollution of plastic molecules.
In the process of promoting biodegradable plastic products and paper tableware, many experts have compared the two in various aspects to see their pros and cons.
From the perspective of the whole production process, there is great pollution in the raw material production process of the two, that is, the production of plastics and pulp; the production process of the two products, the molding process of pulp, there is no pollution, and The use of Freon foam in the production of plastic products causes pollution to the atmosphere.
The consumption process of the two products is even more different in the degree of pollution. Plastic products take hundreds of years to be dissipated, harming the ecological environment; paper tableware only takes a few months to be dissipated by the environment.
Analyze the environmental benefits of the two products: the former has a temporary effect, while the latter has a temporary and fundamental effect.
As packaging materials, plastic products have many advantages such as waterproof, oil-proof, good strength, and light weight. They are good materials for durable packaging. However, as disposable packaging such as fast food trays, its shortcoming of not being easily degraded is difficult for people to accept. Disposable paper fast food tableware is easy to degrade, easy to recycle and easy to handle. Compared with foam plastic tableware, its environmental performance has incomparable advantages.
Whether it is plastic tableware or paper tableware, there are problems with recycling, utilization, and disposal of waste. With the current level of science and technology, people still lack effective methods for recycling foam plastic tableware and packaging. At present, the traditional methods of incineration and landfilling are commonly used by urban management departments. The consequences of this treatment may pollute the air or pollute the soil.
At present, people have advanced methods for recycling paper tableware and paper packaging, and they have good results. The re-making and production of domestic waste paper and cartons has brought new profit growth points to enterprises and presented a virtuous cycle.
