慧聪网塑料听证：随着环保浪潮的影响，消费品，使越来越多的需求。绿色包装是国际环保发展趋势的需要，对包装业的发展趋势，国家的名义，而且是提高产品市场竞争力，以避免新的贸易壁垒的重要内容之一。

在中国塑料软包装工业得到了快速发展，而且有力地推动进展，如食品，日用化工和制药行业，这些行业反过来进一步刺激了塑料软包装薄膜的市场需求的进展。
材料和加工作为塑料软包装凹印改善的地方很多技术正在为人们的生活越来越重要的作用已经从购物袋，商品袋，垃圾袋，冰箱不可分割的新鲜袋;和工业包装，家庭包装，服装包装，药品包装也大量塑料软包装薄膜的使用。
与此适应
，塑料软包装的绿色薄膜已成为重要的趋势之一。论绿色包装并不是一个xx统一的定义。一般来说，可以循环再利用，再循环或腐败退化，在整个人类和环境危害的产品生命周期不会导致适当的包装，称为绿色包装。绿色包装是对环境的最重要的保护意义，而且是可再生资源的重要性。

加强回收再利用，废旧包装实现减少环境污染，生态循环的xxx措施。绿色包装在其整个生命周期的过程中，遵循循环经济“减量化，再利用，再循环”原则对经济活动的开展，使包装降低到{zd1}限度的环境影响。在废塑料回收再利用近年来方面的不断进步，逐步解决二次污染问题。

包装废弃物法规因地不同，但都有一个共同的原则：应当在满足功能下，尽量减少包装垃圾生产的前提下，即鼓励原材料使用。在包装设计应充分利用相同的材料，从共存的材料分离，趋向于使用结构简单，易于回收的材料。因此，呈现出重量轻包装薄膜的发展趋势，其关键技术是采用超韧性，对薄膜加工，更方便的新原料，如聚合物，加工位双峰高密度聚乙烯，茂金属聚烯烃催化剂，以及高质量的包装材料阻隔。

国内塑料包装行业，以减少废物污染已与有关环保法规和本逐步落实了很大的进展，将会取得更大的进展。例如，利用热能封xx拉伸膜加上油价可能会大大减少在寒冷的冰淇淋的包装材料的数量是大量的申请，通过高强度的茂金属聚烯烃，成功降低了厚度包装膜，过度包装也正在逐渐减少，共挤复合材料应用技术及设备也越来越普及，解决的每个问题的薄膜层厚度的xx控制，高价格壁垒层的厚度是可以控制的非常薄，乘以在表现的同时保护好几次，甚至改善。

回收，除了在世界各地所做的工作已经认识到保护环境的重要性和绿色包装薄膜的降解，从而作出新的永无止境的。

(1)可食膜可食性包装膜的基础上xx食用的物质(如多糖，蛋白质等为原料)，通过不同分子间相互作用和多孔网络结构与成膜。如壳聚糖可食包装膜，玉米蛋白质包装膜，改性纤维素可食性膜和复合膜包装食用这种包装，可食用薄膜可应用于各种现成的即食包装内食品，在食品工业中具有巨大的市场。

(2)可降解薄膜主要是为了解决废物，不容易降解包装材料的回收困难的，埋藏在地下会破坏土壤结构，燃烧会产生矛盾与空气污染造成的有毒气体处理。可降解塑料包装薄膜塑料传统功能和特性，而且在生命的完成，通过土壤和水中的微生物作用或通过阳光中的紫外线自然分裂降解作用，并最终恢复重建形式-进入生态环境，回归自然。国内研发品种已涵盖光降解，光降解，光氧生物降解，高淀粉含量型生物降解，高碳酸钙填充光氧化降解，如可生物降解的类别。在降解塑料包装应用，在整个一般包装薄膜，收缩薄膜，购物袋，垃圾袋等，以改善环境起到了积极的作用。

(3)水溶性水溶性塑料薄膜作为一种新型绿色包装材料包装薄膜在欧洲，美洲，日本等国家，广泛应用于各种产品，如农药，化肥，颜料，染料，包装，清洁剂，水处理剂，矿物添加剂，洗涤剂，混凝土添加剂，化学试剂使用，例如摄影，化学试剂及园艺护理。由于水的退化水溶性薄膜彻底，安全，方便使用和其他环境特点，已广泛重视与发达国家在世界上。目前，国外主要有日本，美国，法国和其他国家的生产和销售此类产品，国内企业也已投入生产，其产品是进入市场迈进。 06.9.15

Plastic Film Labels towards the direction of the development of green

Huicong net plastic hearing: With the wave of the impact of environmental protection, consumer packaged goods, made ever-increasing demands. Green packaging is the development trend of international environmental protection needs, but also on behalf of the countries in the packaging industry’s development trend is to enhance the competitiveness of product markets, to avoid new barriers to trade one of the important contents.

plastic flexible packaging industry in China has been rapid development, but also a strong impetus to the food, daily chemical and pharmaceutical industries such as progress, the progress of these industries in turn further stimulate the plastic flexible packaging film market demand.
materials and processing technology as the improvement of plastic flexible packaging gravure in many areas is playing an increasingly important role in people’s lives have been inseparable from the shopping bags, merchandise bags, trash bags, refrigerator fresh BAG; and industrial packaging, household packaging, garment packaging, pharmaceutical packaging is also substantial use of plastic flexible packaging film.

with this adaptation, plastic flexible packaging film of the green has become one of the important trends. On green packaging is not a completely unified definition. Generally speaking, the cycle can reuse, recycling or degradation of corruption, and in products throughout the life cycle of human and environmental hazards do not result in appropriate packaging, called the Green Package. Green packaging is the meaning of the most important protection of the environment, but also the significance of both renewable resources.

to enhance recycling and reuse, waste packaging realize the ecological cycle of reducing environmental pollution are the most effective measures. Green packaging, in its entire life cycle process, follow the circular economy “reduction, reuse, recycling” principles of conduct of economic activities, so that the environmental impact of packaging down to a minimum. In recent years in plastic waste recycling and reuse aspects of the continuous progress, and gradually solve the problem of secondary pollution.

packaging waste laws and regulations vary from place to place, but have a common principle: It should be functional in meeting the packaging under the premise of minimizing the production of garbage, that is, to encourage the use of raw materials. In the packaging design should make full use of the same material, separated from the coexisting materials and tend to use simple structure, easily recycled materials. Thus showing a packaging film of the development trend of light weight, and its key technologies are used with super toughness, to thin film processing and easier processing of new raw materials, such as polymer-bit bimodal HDPE, metallocene polyolefin catalysts, as well as high-quality barrier packaging materials.

domestic plastic packaging industry to reduce waste pollution has been made a lot of progress, with the relevant environmental protection regulations and the gradual implementation of this will make even greater progress. For example, the use of heat sealing Clear stretch film plus oil may significantly reduce the amount of material in the cold ice cream packaging to be a large number of applications; through the use of high-intensity metallocene polyolefin and successfully reduced the thickness of the packaging film ; excessive packaging is also being gradually reduced; co-extrusion composite application technology and equipment is also becoming increasingly popular to solve the precise control of film thickness on each floor of the problems, the high price barrier layer thickness can be controlled very thin, at the same time preservation of performance multiplied several times and even improve.

recycling, except in the work done around the world have recognized the importance of environmental protection and thus in the degradation of green packaging films are made to New endless.

(1)edible films Edible packaging films based on the natural edible substances (such as polysaccharides, proteins, etc.)as raw material, through different molecular interaction and the formation of porous network structure with the film. Such as chitosan edible packaging film, packaging film corn protein, modified cellulose membrane and packaging of edible edible composite film packaging, edible films can be applied to a variety of ready-to-eat food inside the packaging, in the food industry has enormous market.

(2)degradable films mainly to solve the waste and not easily degradable packaging materials recovery difficult, buried underground will destroy soil structure, burning will produce toxic gas deal with air pollution caused by the contradiction. Degradable plastic packaging films plastic both traditional functions and features, but also after the completion of life, through the soil and the microbial role in the water or through the sun’s ultraviolet role in the degradation of natural split, and ultimately to restore the form of re - to enter the ecological environment, the return to nature. Varieties of domestic R & D has been covered by photodegradation, biodegradation light, light oxygen biodegradable, high-starch content-based biodegradable, high-calcium carbonate-filled light-oxidative degradation, such as biodegradable categories. Degradable plastics in packaging applications has been throughout the general packaging film, shrink film, shopping bags, garbage bags, etc., in order to improve the environment has played a positive role.

(3)water-soluble water-soluble plastic film packaging film as a novel green packaging materials, in Europe, America, Japan and other countries are widely used in the packaging of various products, such as pesticides, fertilizers, pigments, dyes, detergents, water treatment agent, mineral additives, detergents, concrete additives, chemical reagents used photography and gardening care, such as chemical reagents. Due to degradation of water-soluble film thorough, safe and convenient to use and other environmental characteristics, it has been given extensive attention to developed countries in the world. At present, the foreign principal has Japan, the United States, France and other countries production and sales of such products, domestic enterprises have also been put into production, and its products is moving into the market.
