软塑包装材料的阻隔性与食品安全.ppt

* MOCON的BPC, 使测试结果不受环境大气压影响 * * …引起的后果是…… 产品变质 生病 退货 打官司 公司形象的损坏 你愿意为便宜仪器付出如此大的代价吗? * 所以, 请您相信MOCON, 因为…. * The Oxtran 2/21 are two cell systems typically used in RD applications. Here we have a photo highlighting some points of the instrument including the self-contained heating/cooling unit, self-contained pump plumbing and the self-humidifying, patented, Coulox sensor. * * 看看吧, 所有这些国际标都以MOCON仪器来制定的 MOCON is very proud to have ASTM and other standards that reference MOCON Instruments and related test methods. * * 请你相信MOCON, 因为全世界有那么多人相信MOCON, 为什么你不? * 请你相信MOCON, 因为全世界最有名的公司都在使用MOCON, 希望有一天你的公司也走进世界五百强! * 总而言之, MOCON产品在全球范围内是包装材料测试的三个代表…… * * * * * * * * * * * * * * Results Sample W-6 (without cap) demonstrated the lowest WVTR value, while the WVTR value of other samples (with closures) varied and were much higher than the bottle body by itself. The higher value of these capped bottles could result from permeation from different closure and liner materials. It could also result from micro-leakage through the cap/bottle opening interface due to physical design, improper sealing parameters. * * * * * * The ultimate goal of packaging is to provide the sufficient barrier that the product can maintain its quality within desired shelf life. On the other hand, one does not want the expense of over-packaging the product. In order to select packaging materials wisely, one should combine all his technical, geographical and economical knowledge. The company produces waffle products which are exported to three different global regions. Due to the different environmental condition in each region, different grades of packaging materials could be chosen to achieve the desired shelf life. Three grades of film materials were tested at three test conditions that mimic the environment of these three regions. Results showed that Film A is the only choice for Vietnam due to its tropical condition. For the other two regions, more than one film can be chosen. Now is the t
