记者从全国标准化技术委员会最近的塑料制品获悉，秘书处，我们对食品包装的国家标准制定普通类第一个规格已经完成。该标准是“包装复合膜，袋一般”的建议为国家标准批准有关程序。

据了解，被广泛应用于塑料食品包装材料，包括聚乙烯，聚丙烯，聚酯，聚酰胺，聚偏二氯乙烯，聚碳酸脂，聚乙烯醇，高塑性和新材料等内容。复合包装材料的主要原料为两个或两个以上的包装材料层将塑料与铝箔，纸，玻璃纸等辅助材料。

塑料制品，根据国家标准化技术委员会，介绍了秘书长陈家琪，我们为不同的复合材料已经开发超过20可用于食品包装标准和当前的全球复合材料用于食品包装多达1000种随着科技的进步，新材料也将是永无止境的。和包装复合膜，产品品种及成型方法和产品结构和广泛应用，因此更迅速变化的每个复合材料分别制定标准，品种，复合袋将永远不能满足食品包装的要求。制定国家标准一般类别，不管如何复合包装材料的组合，为相关标准制定的基本要求，首先所有规范，特别是各类包装企业发展有指导意义的企业标准。

据介绍，我国食品包装标准，第一类是一般的国家标准，标准制定过程中收集所有相关的国家标准，行业标准和部分企业标准，而且还收集了10多个先进国家相关的标准，筛选和综合分析，对重点提到日本，英国，欧洲联盟，澳大利亚，美国和台湾的标准。

不同材料，不同包装复合膜的方法作出规定的标准，复合袋的术语，分类，技术要求，试验方法，检验规则的要求。涉及外观质量，印刷质量，规格及力学性能等四个方面，技术要求。物理力学性能，优良分为拉关闭，直角撕裂性能，粘接强度，热强度，穿刺强度，氧气透过性，耐热性，耐压性能，性能下降，表面电阻率，透明度等16的要求。陈家琪

说，这些要求是基于包装用复合膜，袋的共同项目的要求确定。虽然食品包装材料，卫生标准不标准，但许多标准，都可以影响食品卫生的技术要求。作为国家标准时，涉及的特定产品，一般类，由于结构组合，尺寸规格，如绝育手术的不同结果，有些项目可能同意的供需双方。例如，食品包装，该标准必须衡量的外观，规格，拉伸性能，热强度，剥离力，溶剂残留量等，其余双方同意的供应和需求的基础上选择这一标准，新增和改善。值得注意的是，该标准检测项目，该国绝大多数相应的测试方法标准，穿刺强度和耐热性两项没有国家标准检验方法，它采用国际先进标准检验方法。

的专家认为，标准的产品面临着广泛的验证样本量大与有关国际规定的技术指标范围内的标准和指标，可以比较，我想基本满足中国的食品安全要求的需要有关指标。 06.8.1

Composite packaging of food in our country to develop national standards

Journalist recent plastic products from the National Standardization Technical Committee was informed that the Secretariat, our first specification of the General category of food packaging the formulation of national standards has been completed. The standard that is “packaging composite membrane, BAG General” as recommend approval of national standards into the procedures.

It is understood that is widely used in plastic food packaging materials, including polyethylene, polypropylene, polyester, polyamide, polyvinylidene chloride, polycarbonate, polyvinyl alcohol, and other new materials of high plastic elements. Composite packaging materials are the main material will be plastic and aluminum foil, paper, cellophane and other auxiliary materials into two or more than two layers of packaging material.

plastic products, according to the National Standardization Technical Committee, introduced the Secretary-General CHEN Jia-qi, we have for different composite materials developed more than 20 can be used for food packaging standards and the current global food packaging for the composite material up to 1000 species, with the advance of technology, new materials will also be endless. And packaging composite membrane and composite bags of product variety and molding method and more rapid changes in product mix and wide application, therefore, for each species of composite materials, respectively, standard-setting will never be able to meet the requirements of food packaging. Develop a general category of national standards, regardless of how the combination of composite packaging materials, first of all norms of the basic requirements for the formulation of relevant standards, especially the various types of packaging companies to develop the enterprise standard of guiding significance.

According to introduction, the standard of our food packaging are the first category General National standards, standard-setting process to collect all the relevant national standards, industry standards and standards of some enterprises, but also collected more than 10 advanced countries in the relevant standards, and comprehensive analysis of screening, focusing on reference to Japan, the United Kingdom, the European Union, Australia, the United States and Taiwan standards.

the standard provided by different materials, different ways of packaging made of composite membrane, composite BAG terminology, classification, technical requirements, test methods, inspection rules requirements. Technical requirements related to the appearance of quality, print quality, specifications and mechanical properties, such as four aspects. Physical and mechanical properties, the fine is divided into pull off, and right angle tear properties, bonding strength, thermal strength, puncture strength, oxygen through sexual, heat resistance and pressure resistance performance, the performance drop, surface resistivity, transparency, etc. 16 requirements. CHEN Jia-qi

said that these requirements are based on the packaging with composite membrane, BAG common project requirements identified. Although the food packaging materials, hygiene standards are not the standard, but many of the standards can affect all the technical requirements of food hygiene. As a general category of the national standard, when involved in a specific product, as a result of structural composition, size specifications, such as sterilization procedures vary, some items may be agreed by the two sides of supply and demand. For example, food packaging, the standards must be measured appearance, specifications, tensile properties, thermal strength, peeling, solvent residue, etc., and the remaining two sides agreed to by the supply and demand, in this standard based on the selection, added and improved. It is worth noting that the standard test items, the vast majority of the country have the corresponding test method standards, puncture strength and heat resistance of two no country standard testing methods, it adopts the international advanced standard testing methods.

the experts think, the standard products face extensive validation sample volume is very large, with relevant international standards set out in the scope of technical indicators and their indicators can be compared with, and I would basically meet the needs of China’s food safety requirements of the relevant indicators .
