平板玻璃是建材产品中的重要工业产品,是一种批量大,比重高、易碎、流向面广的产品。1987年全国玻璃产量发展到5500万重箱,年流通量约275万吨。平板玻璃产品历来使用花格木箱包装,包装费用高,消耗木材量大,若全部使用木箱包装,每年国家要消耗木材46万余立方米。其包装成本占玻璃成本的15～18％而且流通过程中玻璃破损严重,全国年损失玻璃高达275万重箱,木箱包装运输中车辆净载率仅达70～85％,浪费运力惊人。随着玻璃产品逐年增长,浮法玻璃生产新工艺相继使用,落后的木箱包装已不适应生产技术发展的需要,改革木箱,研究新材料,采用新的包装型式,势在必行。
Flat glass is an important industrial product of building materials, is a large volume, high proportion, fragile, a wide range of products. In 1987, the glass production in the country grew to 55 million boxes, with an annual liquidity of about 2.75 million tons. Flat glass products have always been using grate wood packaging, packaging, high cost, large amount of wood consumption, if all use wooden packaging, the country each year to consume 46 million cubic meters of wood. Its packaging cost accounts for 15% to 18% of the cost of glass. In addition, the glass is damaged severely during the circulation. The annual loss of glass in China is as high as 2.75 million boxes. The net loading rate of wooden boxes is only 70-85%. With the annual growth of glass products, float glass production has been the use of new technologies, outdated wooden box packaging has not meet the needs of the development of production technology, reform of wooden boxes, the study of new materials, the use of new packaging models, imperative.
