Ordinary plastic is still the main force in the packaging market
with the increasingly stringent requirements of environmental protection, traditional plastic packaging is increasingly challenged by degradable plastic packaging and paper packaging. Can degradable plastic packaging and paper packaging completely replace ordinary plastic packaging? A few days ago, many industry experts said that ordinary plastics will still occupy the market of packaging raw materials, and blow molding machines will play an important role in soft packaging into food
Tang saizhen, senior engineer of China Light Industry Information Center, said that it is impossible and unnecessary for degradable plastic bags to completely replace ordinary plastic bags, because all kinds of plastics have their own positioning. Degradable plastics are mainly positioned on consumer goods that are disposable, difficult to collect, dirty and uneconomical to recycle
for the current situation that paper packaging is popular, Yuan Guangyu, a professor of the Department of environmental science and engineering of Tsinghua University, believes that although paper packaging is biodegradable, paper products produce several times more pollution than plastics in the process of production, recycling and reuse. Combined with the strategy of sustainable development, it is unscientific to advocate replacing plastic with paper
point C was learned from Zheng Kai, Secretary General of China Engineering Plastics Industry Association; Or take the remaining grid number [odd number, in the future, packaging will be the largest application field of plastics, and ordinary plastics will still be the protagonist in the packaging raw material market.
