食品包装迁移量测试仪

p　　食品包装材料指包装、盛放食品或者食品添加剂用的纸、竹、木、金属、搪瓷、陶瓷、塑料、橡胶、天然纤维、化学纤维、玻璃等制品和直接接触食品或者食品添加剂的涂料。由于食品包装材料直接与食品接触，《食品安全法》第三十三条规定：“(七)直接入口的食品应当使用无毒、清洁的包装材料、餐具、饮具和容器。”因此，必须保证包装材料自身的安全无毒和无挥发性物质产生，同时，在包装工艺的实施过程中，也不会产生与食物成分发生化学反应的物质和化学成分。/pp　　span style="color: rgb(0, 112, 192) "strong一、食品包装材料的风险/strong/span/pp　　由于包装材料组成的复杂性, 食品包装材料中的物质析出，出现于食品中, 可能是由于这些物质向食品的迁移, 或由于意外萃取而出现于食品中。这样造成食品包装的化学迁移也给食品带来负面的影响。主要表现为两个方面：/pp　　一方面合成包装材料中的有害物质迁移到食品中导致对人身健康造成损害,/pp　　另一方面迁移物质可能造成食品感官状态的劣变, 如产生异味、色变和有污点出现等。/pp　　现代食品包装采用大量的化学合成物质,总体而言可以分为两大类: 即已知成分和未知成分。这些物质主要包括:/pp　　合成材料的单体和其他合成材料物质、催化剂、溶剂和悬浮介质、包装材料添加剂(包括抗氧化剂、抗静电剂、抗雾剂、增塑剂、热稳定剂、成核剂以及染料和色素)。/pp style="text-align: center "　　span style="color: rgb(0, 112, 192)

"strong二、各国食品包装材料有害物质的标准要求/strong/span/pp　　为了有效控制食品包装材料中的有害物质，许多国家制定了食品包装材料中有害物质的限制标准。/pp　　欧盟食品接触材料法规包括框架法规、专项指令和单独指令3个层次。其中，框架法规规定了对食品接触材料管理的一般原则，专项指令规定了框架法规中列举的每一类材料的系列要求，单独指令是针对单独的某一具体有害物质所做的特殊规定。/pp style="text-align: center "img title="1.jpeg" src="http://img1.17img.cn/17img/images/201706/noimg/153f7f73-c625-461c-a6fa-e9ec8cba8ff5.jpg"//pp　　美国对食品包装材料的管理主要通过联邦法规CFR来进行规范。美国联邦法规CFR第21部分主要规范食品和药品的管理，其中第170-186节规范了食品包装材料的管理要求。21 CFR 174(间接使用的食品添加剂-总论)规定了食品包装材料的通用要求和用于与食品接触的物质的法定限量。其中对与食品接触材料的通用要求为：材料需要按照GMP要求生产 材料需要使用符合21 CFR 170-189法规中批准的物质 新材料必须经过FDA审核和认可才可进入市场。/pp　　21 CFR 170-189对于食品接触材料有非常详尽的管控要求。除通用要求之外，针对纸张、木材、塑料、涂层、橡胶、胶黏剂等均有相应规定，如图2所示。在不同材料的相应要求章节，既包含该材料生产所允许使用的单体、添加剂、助剂，同时涵盖其纯度、用量等要求，也有对成品的溶出物、特定物质的溶出等测试要求，某些塑料材料还有物理性能(如密度、熔点、分子量、溶解度等)的要求。/pp style="text-align:

31603.1-2015《食品接触材料及制品迁移试验通则》规定了食品模拟物、特殊迁移及总迁移测试条件的选择。食品接触材料添加剂标准(GB 9685-XXXX)与GB 9685-2008相比更为合理，主要变化是调整了附录化学物质清单的结构(对塑料、涂料涂层、橡胶、油墨、粘合剂、纸、硅橡胶中的添加剂分别说明)，将添加剂名单及其使用要求按照使用范围进行分类，同时添加剂品种由959种扩充到1297种。/pp style="text-align: center "　img title="3.jpeg"

连日来，江苏常州检验检疫局食品接触材料国家重点实验室在对有色塑料饭盒、塑料杯等食品接触材料进行检测时，发现部分样品存在着色剂迁移(脱色)的现象，从而造成了食品或食品模拟物染色的现象。　　据介绍，着色剂主要分为有机着色剂和无机着色剂。部分无机着色剂含有毒性较大的重金属，特别是汞、镉、铅、铬等。有机着色剂也常会分解一些致癌、致突变等有机毒害物质，如一些偶氮染料会裂解释放苯胺、联苯胺之类的致癌芳香胺。　　常州检验检疫局提醒相关输欧食品包装容器生产企业，关注产品的着色剂迁移。生产企业要把好原料质量关，对原料、着色剂进行有效控制，杜绝使用法规明确禁止或“非食品级”的着色剂、添加剂，并改进生产工艺和配方，避免因工艺不成熟导致着色剂迁移。同时，消费者在日常使用过程中发现食品接触材料有脱色的现象，应立即停止使用。

食品包装企业在确保产品质量和安全方面扮演着至关重要的角色。薄膜拉力机、摩擦系数仪和密封性测试仪是品控过程中不可或缺的仪器，它们各自在包装材料的测试和质量控制中发挥着独特的作用：薄膜拉力机：薄膜拉力机用于测量包装材料（如塑料薄膜、复合材料等）的拉伸强度、断裂伸长率、弹性模量等力学性能。这些参数对于评估包装材料的耐用性、抗破损能力和在实际使用中的可靠性至关重要。通过拉力机测试，可以确保包装材料能够承受一定程度的物理冲击和拉伸，从而避免在运输和存储过程中出现破损。摩擦系数仪：摩擦系数仪用于测定包装材料的滑动摩擦系数，这对于评估包装材料在生产线上的运行特性非常重要。低摩擦系数可以减少包装过程中的磨损，提高生产线的效率，同时也可以降低包装材料在储存和运输过程中的粘连问题。适当的摩擦系数有助于确保自动包装机械的顺畅运作，减少停机时间和材料浪费。密封性测试仪：密封性测试仪用于检测包装的完整性和密封强度，这对于食品包装尤为重要，因为密封的可靠性直接关系到食品的保质期和卫生安全。通过密封性测试，可以确保包装无泄漏，防止外界污染物和微生物的侵入，保障食品的质量和安全。密封性测试也有助于检测包装材料的耐压性和耐穿刺性，特别是在包装易碎或易受外界环境影响的食品时。综上所述，薄膜拉力机、摩擦系数仪和密封性测试仪是食品包装企业品控的必备仪器，它们分别从材料的力学性能、生产线的运行效率和产品的安全密封性等方面，为保证食品包装质量提供了强有力的技术支持。通过这些仪器的严格测试和控制，食品包装企业能够提供更加可靠和安全的包装解决方案，满足消费者和法规的要求。更多相关产品信息、解决方案、行业动态可关注山东泉科瑞达仪器官网
