新型“环保”食品包装材料持续创新和探索

As a packaging material, plastic is an important symbol of the development of modern packaging technology, because of its rich source of raw materials, low cost and excellent performance, it has become one of the world's rapid development and huge consumption of packaging materials in the past 40 years. It is a kind of high molecular polymer, its macromolecular special structure makes plastic has a series of special properties: chemical inertia, insolubility, strength and toughness.

In China, there are as many as 15 or 6 kinds of plastics used in food packaging, such as PE, PP, PS, PET, PA, PVDC, EVA, PVA, EVOH, PVC, ionic bond resin, etc. But we cannot deny that plastic excellent high resistance to oxygen, high resistance to moisture, radiation radiation resistance, low temperature resistance and so on to bring a lot of benefits to the food industry. However, it is difficult for plastics to degrade naturally in the environment. With the increase of human use, waste plastics accumulate in the environment, causing serious damage to the ecological environment and varying degrees of harm to humans and organisms.

目前，国内外市场上流行的“环保”包装材料主要有纸包装、可降解塑料包装、生物包装材料等，像KFC推出的可吃包装纸；美国将乳酸进一步聚合制成生物可降解塑料；意大利利用玉米淀粉生产生物可降解塑料。我国生物可降解塑料发展也很快，如以薯类、玉米等淀粉制成的食品容器、“光——生物双降解”塑料等，像嘉美塑料制品有限公司就推出了两款可降解餐具制品，例如“光降解”无机碳粉所制造成餐具，和生物可降解原料制成的餐具；说明国内外都在对“环保”食品包装材料在不断地探索和创新。

At present, the popular "environmental protection" packaging materials at home and abroad mainly include paper packaging, biodegradable plastic packaging, biological packaging materials and so on. Lactic acid is further polymerized to make biodegradable plastics in the United States; Italy USES corn starch to produce biodegradable plastics. Development of biodegradable plastics in our country also quickly, such as a food container made of potato and corn starch, "light of biological degradation plastics, etc., like jiamei plastic products co., LTD., launched two new biodegradable tableware products, such as" light degradation "inorganic carbon powder made into tableware, and the tableware of biodegradable material; It indicates that the "environmental protection" food packaging materials are constantly explored and innovated at home and abroad。

But for now, biodegradable packaging costs more than plastic, and many companies worry that rising prices will reduce consumers' desire to spend. But according to camilla's international consumer survey, 85 percent of Chinese consumers responded positively to the question of "I'm willing to pay more for renewable packaging of food, such as cardboard boxes or other biological materials." In addition, 65 percent of respondents in first-tier cities believe that food manufacturers should bear the main responsibility for reducing the amount of plastic waste in packaging.
