国外食品包装一般都采用纸盒、纸袋、纸筒、纸罐等各类纸质容器。我国的纸质包装虽已起步,但发展滞后于国际步伐,需进一步在包装纸张的性能及成本,纸包装机械及包装技术、纸包装容器设计等方面加快研究开发的步伐。这涉及到造纸、机械、包装等多行业的合作。发展纸质包装容器,不仅会带来许多商机,亦是环境保护的必然趋势。 现代包装四大材料纸、塑料、玻璃、金属中,由于纸和塑料价格便宜、便于加工,且原料来源广泛,不像玻璃那样易碎,不像金属那样重,因此纸和塑料包装材料在日常生活中应用面广。然而,塑料包装材料由
Foreign food packaging are generally used cartons, paper bags, paper tubes, paper cans and other types of paper containers. Although the paper-based packaging in our country has started, its development has lagged behind the pace of international development and further accelerated the pace of research and development in terms of the performance and cost of packaging paper, paper packaging machinery and packaging technology, and design of paper packaging containers. This involves papermaking, machinery, packaging and other multi-industry cooperation. The development of paper packaging containers will not only bring many business opportunities, but also an inevitable trend of environmental protection. Modern paper, plastic, glass and metal are widely used in paper, plastic, glass and metal. Since paper and plastic are cheap and easy to process, they are not as fragile as glass and not as heavy as metal. Therefore, paper and plastic packaging materials are widely used in daily Wide range of applications in life. However, plastic packaging materials by
