2005年11月，据报道，美国科学家利用等离子体气相沉积技术，此外，还形成一层柔软的塑料瓶的聚酯薄膜，使瓶子装的食物保持新鲜。据介绍，塑料表面涂层可以减少10％以上的氧气。涂料类似石英，不到3毫米的厚度，并在回收的塑料瓶是没有必要的特别待遇。

二零零五年6个月，英国一家公司成功开发了塑料食品包装新类型，有两个被动和主动屏障功能类型，可有效抑制氧渗透，甚至在食品袋，煮熟后的作用仍不会减弱。新包装不仅可以延长食品包装的保质期，但也可以直接微波加热的利用，特别是方便食品包装适合。这个由6层不同材料复合新包装。聚丙烯的{dy}层-以石油为基础的高分子材料具有高抗;第二层和第四层为粘和塑料之间的高分子材料，是阻氧EVOH的(被动屏障)，第五层是除氧剂，称为混合主动屏障，不仅可以阻止外来氧分子进入，而且氧包装吸附;是{zh1}的聚丙烯材料层。聚丙烯生产的乳制品是理想的发热材料的容器，在高温xx过程EVOH的材料，由于水分渗入的结果，屏障功能降低，导致50天之后，产品具有变色，变味的可能性。新包装，除氧剂即使在有水的情况下，仍然能够保持活性，从而保证了食品的保质期。

密西西比美国已采取在常规包装袋特洛伊城的添加一项新的塑料薄膜包装方法层，初步收到良好的效果。这部电影包括一些xx的Amosorp的化学物质，可以xx氧包装袋。经过长期反复的实验表明，存放在新的新鲜食品袋，可以达到长期保存的效果。澳大利亚韦恩手乐斯也进行了类似的研究。科学家们采取填补混合化学物质的方法生产的塑料袋，但不进行除氧，而是xx的口袋，以促进果实成熟，变质的气体，使长期的水果长期保存。澳大利亚的研究小组也进行了一项试验除氧器化学品。具有类似Amosorp物质的{wy}保存较好的物理性能。这是说，在特殊光线照射前的材料，在休眠状态，当光线照射，接受其中的化学分子才可以正式运作了。这就是说，在包装食品，对除氧器需要综合xx，只要有特殊光线照射过程中的包装食品的{zh1}一行可以。

为了防止这种情况发生，德国科学家利用医药专业技术，开发了一种xx塑料食品包装材料，以防止这些不速之客的传播。这种包装利用{zx1}表面涂层技术在塑料包装薄膜，增加了一层防腐蚀涂料的xx物质，以取代在食品中添加防腐剂，以进一步加强食品包装安全。这种涂层可以材料，如复合树脂基材料和特殊技术。据悉，这项新技术是一种重要的食品包装的变化，它不能有食品防腐剂，以防止食物霉变将能发挥作用。

加拿大毒素预警公司开发出一种新的包装材料病原体测试。该包装材料可检测沙门氏菌，弯曲杆菌，大肠杆菌0157，4致病菌种含有李斯特菌。当包材料接触到受污染的食物接触时，发生褪色反应。该包装材料还可以用于检测害虫或基因工程食品的蛋白特性。集团分别为80％的聚合物薄膜，其余是金属箔与板材。

法国展开了新的包装膜，食品包装可以通过是否使用转基因原料，确定了聚氯乙烯材料的普遍使用。这种特殊待遇由使用PVC包装膜的使用，可以判断，如从大豆转基因大豆为原料制成豆油此包的内容，即使只有5-10％，也清楚地证实含有转基因大豆。该包装膜主要用于欧洲南部，培育非转基因大豆作为后续检查和保证流程，是不是转基因大豆原料的粥。

英国研究人员最近研制成功一种xx的PHB塑料包装材料的新类型，可广泛用于食品包装行业。通过使用技术培菌，用糖产生一种xx，然后通过特殊的加工工艺类似的聚丙烯材料制成的技术。该产品xx，可生物降解，对环境没有污染。 06.9.6

Food plastic packaging new technologies progress

November 2005, according to reports, U.S. scientists using plasma vapor deposition technology, in addition to form a layer of plastic bottles soft polyester film, enabling the bottle to keep fresh food loaded. According to introduction, the plastic surface coating can reduce more than 10% oxygen. Coating similar to quartz, the thickness of less than 3 millimeters, and the plastic bottles in recycling is not necessary for the special treatment.

2005 years 6 months, the United Kingdom a company successfully developed a new type of plastic food packaging, with two types of passive and active barrier function, can effectively inhibit the infiltration of oxygen, even in the food bag after cooking, the role is still will not be weakened. New packaging can not only prolong the shelf life of food packages, but can also direct the use of microwave heating, particularly suitable for packaging convenience foods. This new packaging from 6 layer composite made of different materials. The first layer of polypropylene - an oil-based polymeric materials with high resistance; second layer and fourth layer is sticky and plastic, between the polymeric materials are oxygen resistance EVOH (passive barrier); the fifth layer is a mixture of Oxygen Scavenger , called the initiative barriers, not only can prevent external oxygen molecules to enter, but also adsorption of oxygen packaging; are Finally a layer of polypropylene material. Polypropylene manufacturing dairy products are ideal heating material containers, EVOH materials in high-temperature sterilization process, as a result of moisture ingress, resulting in reduced barrier function, 50 days after the Products have the possibility of discoloration and变味. The new packaging, Oxygen Scavenger, even in the case of water has still be able to maintain activity, thus ensuring the shelf life of foods.

Mississippi United States has taken the city of Troy in the conventional packaging bag Add a layer of plastic film packaging methods, the initial received good results. The film contains a chemical known as Amosorp material, can remove oxygen packaging bags. After a long period of repeated experiments show that deposited in the fresh new bag of food, can achieve the effect of long-term preservation. Australia Wayne Hand Lorsban also conducted similar studies. Scientists have taken to fill a plastic bag of mixed chemical substances produced in the method, but does not carry out deaeration, but the elimination of pockets to promote the fruit ripe, metamorphic gases, so that long-term preservation of fruits. Australian research group has also conducted a pilot deaerator chemicals. The physical properties of substances with similar Amosorp only better preservation. It is said that the material in the special light before irradiation, has been in hibernation, when the acceptance of light irradiation, in which chemical molecules only become active. That is to say, in packaged foods, the need for complex treatment deaerator, as long as the last line of packaged foods with special light irradiation process can be.

in order to prevent this from happening, the German scientists using medicine expertise, developed a anti-bacterial plastic food packaging materials in order to prevent the propagation of these uninvited guests. Such packaging using the latest surface coating technology, in the plastic packaging films add a layer of anti-corrosion coating of antibacterial material, to replace preservatives in foods to add to further enhance the safety of food packaging. This coating can be material such as composite resin-based material and a special technique. It is said that this new technology are an important food packaging change, it can not have food preservatives to prevent food mildew will be able to play a role.

Canada Toxin Alert Inc. developed a new pathogen testing of packaging material. The package material can be detected Salmonella, Campylobacter, E. coli 0157, four kinds of pathogenic bacteria Listeria monocytogenes. When packet materials come into contact with contaminated food happen when the discoloration reaction. The package material can also be used to detect pests or genetically engineered protein characteristics of foods. Group were 80% for the polymer film, and the rest are metal foil and sheet.

France launched a general use of polyvinyl chloride materials into new packaging films, food packaging can be identified by whether or not to use genetically modified raw materials. The use of such special treatment by the use of PVC packaging film, can determine the contents of this package such as soya bean oil for raw materials made from genetically modified soybeans, even though only 5-10% containing genetically modified soybeans also clearly confirmed. The packaging film is mainly used in southern Europe, cultivated for non-genetically modified soybean, as a follow-up inspection and guarantee the flow of the process is not genetically modified soybean gruel of raw materials.

British researchers have recently successfully developed a new type of bacterial PHB plastic packaging materials, can be widely used in food packaging industry. The technology through the use of technology-pui bacteria, use sugar to produce a kind of bacteria, and then made through special processing technology similar to polypropylene materials. The product non-toxic, biodegradable, no pollution to the environment. (06-9-6)
