Environmental protection policies and eco-friendly tableware products
Since the first use of disposable tableware in China in 1984, polystyrene (eps) as the main raw material of the foam plastic tableware quickly spread to every corner of our country, into the daily life of passers-by, forming a huge consumer market. According to statistics, China’s annual consumption of fast food utensils is about 10 billIon, most of which are disposable foam plastic tableware, and an annual growth rate of 25%.
The disadvantage of polystyrene being non-degradable, difficult to recycle, and other shortcomings have brought great inconvenience to the processing work. After several years of hard efforts, China’s pulp molded disposable tableware production process, technology, and equipment have been developed rapidly, in the varieties, Has developed a cold, hot catering needs of all kinds of tableware (such as fast food boxes, various sizes of the cup, dish, plate, bowl); All kinds of food plate, vegetable and fruit plate used in supermarket. In the performance, has been fully able to meet the Chinese diet, can contain hot soup oil, not leakage requirements.
According to China’s plastic restrictions and bans-related policies, if only express delivery and takeout areas are considered, the withdrawal of non-degradable plastic products from the market will generate 1.43 million tons of demand for plastic-prohibited replacement products.
Market demand increased, a large number of environmental protection tableware products came into being, various, good and bad, let us have no clue. Industry veterans, people who are new to the industry, capital giants began to pay attention to the investment in this industry, pulp molding industry prospects are bright, the road is still difficult.
China’s modern pulp molding industry
China’s modern pulp molding industry has been developing for nearly 40 years in China, starting from Hunan in 1984, and leading in some fields in the world. However, it should be noted that the industry is still in its infancy, the total market is developing rapidly, but it is still in the process of running in, and many technologies are still being updated.
There are so many companies that do business in this industry, but not means all are professional and supply qualified products. From production environment, factory location, mold design, raw plant fiber source, quality control team, process, even production equipment, every step is important. Not only does it affect the quality of the product, but it also has a great impact on the price.
Biodegradable sugarcane bagasse tableware manufacturers misunderstanding of energy saving and low cost without cutting edge
At present, many Chinese manufacturers of biodegradable sugarcane bagasse tableware still use manual equipment, with the continuous development and use of semi-automatic and fully automatic equipment, manufacturers on the understanding of the non-cutting edge is also varied, each has its own opinion.
Ministry of Industry and Information Technology of the People’s Republic of China issued the “pulp (plant fiber) molding disposable tableware production line industry standards,” the definition of non-cutting edge is: “Using a special process, The process of achieving the same effect as trimming without the use of a blade or a punching process”. Performance requirements for untrimmed edges: “No cutting edge products should be no cracks, no edge, no damage phenomenon; And when 100 products are stacked together, there is no obvious white area and obvious rough edge around, the edge deviation of products should not exceed ± 0.5mm”.
The non-trimming problem has been explored for more than 20 years, 1998 applied for a patent on non-tripping. According to the theoretical calculation and practical summary, the free trimming process consumes more energy than trimming technology.
1. According to the process of the free edge, if the pulp concentration is high, the free edge effect is very poor, rough edge serious. Therefore, the production of non-cutting edge products, pulp concentration is much lower than cutting edge. In general, cut edge product pulp concentration: 4-5%; Free-edge products 2-3%. The same production of 1 ton products, vacuum filtration molding when the displacement to increase a lot, almost 2 times or more. That is to say, the production of free-cutting products consumes much more than the vacuum of cutting products. Vacuum and heating are the main energy consumption in the pulp molding process.
2. Free trimming process In order to reduce the effect of burr, in hot stamping die, to go through a longer virtual pressure process, otherwise there will be a “Fried edge” phenomenon or more burr. The so-called “virtual pressure” is the hot pressing die, the upper and lower hot-pressing mold is not pressed when the closure, The “went blank” in the mold is baked for a certain period of time, and when the “green blank” is baked to a certain dryness, the mold closing force is applied for hot pressing.
This virtual pressure baking process wastes a lot of heat, another adverse effect is the product density is very low. For example, the same 300 10-inch disc products stacked together, free trimming products than normal products to be higher than 30-50CM, greatly increasing the packaging, transport costs.
3. Raw material problem of free edge products, according to the feedback of many manufacturers who used free edge production, Bagasse pulp, wheat straw pulp, and other 100% straw pulp can not achieve the same free edge cutting effect, to add a certain amount of wood pulp for mixing, to achieve a certain effect.
4. No cutting edge molding mold high prices
5. The yield of the free edge is lower than that of the non-free edge. It can be seen from the above points: The discharge volume of the no-trimming process is large, the absorption time is long, leading to a reduction in productivity; the Long virtual pressure process leads to the reduction of productivity.
6. Size edge problem, because the mold thermal expansion is inevitable, and the suction filter molding mold has no thermal expansion. So when the wet blank is transferred to the hot pressing mold, it will inevitably produce offset, so the size of the edge problem is inevitable. In particular, large table (more than 1500 table) equipment.
In summary and practical verification, the production cost of free edge products is sometimes 20% higher than the edge products.
Biodegradable sugarcane tableware situation in china.
According to the report from biodegradable pulp molding associations of China, the production equipment used by some biodegradable sugarcane tableware factories, performance is unstable, so it’s impossible to ensure the stable quality of tableware. In this way, how to believe that their biodegradable sugarcane tableware can reach the international food standard level? In another way, that’s also the reason why some biodegradable sugarcane tableware manufacturers have patents on production equipment.
UV Tableware is one of this kind of supplier, who paid high “study fee” at the beginning, but the CEO of UV Tableware who supplied much more technical support in industry associations said that the huge investment is good for their growth, and it has laid a solid foundation for their stable product quality and industry position.
