我国肉类总产量自1990年以来居世界第一。面膜包装袋材质绝大少数爲含铝箔或镀铝,面膜袋的物理特性和本身需求是:在铝箔包装袋上除了优秀的功能反映,最直观的就是质感的表现。真空袋真空除氧除了抑制微生物的生长和繁殖外,另一个重要功能是防止食品氧化,因油脂类食品中含有大量不饱和脂肪酸,受氧的作用而氧化,使食品变味、变质。此外,氧化还使维生素A和维生素C损失,食品色素中的不稳定物质受氧的作用,使颜色变暗。所以,除氧能有效地防止食品变质,保持其色、香、味及营养价值。自动包装卷膜3D跨度走势图是自动包装机上专用的包装 材料,因为这种包装材料的使用比包装袋的包装 效率更高,因此,它的使用量和市场销售量越来高。但我国深加工肉制品的比例仅不到肉类总产量的10%。世界发达国家普遍达到50%左右,有些国家甚至达到70%以上。与世界先进水平相比,我国肉制品特别是肉制品品种和质量存在较大差距。其关键原因与肉制品的包装技术有关,主要是软包装技术的发展。食品铝箔袋
