日本一家公司的技术人员研究出一种适合长途运输而费用又较低的水果包装新技术。该项技术是在水果包装容器上钻一定数量的孔,在孔上粘贴一层聚硅酮透气型高分子薄膜,这层膜能通过并排出氧气,而二氧化碳则不易透过,这样在包装容器内就能保持一定的气体浓度。采用这种包装技术,在15天的运输期内,水 A Japanese company’s technicians developed a new technology for fruit packaging that costs less for long haul transportation. The technology is in the fruit packaging container to drill a certain number of holes in the hole paste a layer of silicone breathable polymer film, the film can pass and exhaust oxygen, while the carbon dioxide is not easy to penetrate, so that the packaging container Within a certain gas concentration can be maintained. With this packaging technology, water is delivered during the 15-day shipping period
