可降解性薄膜是什么你知道吗?

　　Do you know what a degradable film is?

　　可降解薄膜既具有传统塑料的功用和特性、又可在抵达运用寿命之后，经过土壤和水中的微生物作用或经过阳光中的紫外线的作用，在自然环境中团结降解，比较终以恢复方式重新进入生态环境中，回归大自然。国内研发的品种已涵盖光降解、光生物降解、光氧化生物降解、高淀粉含量型生物降解、高碳酸钙填充型光氧降解、全生物降解等。其中比较常用的是可食性薄膜和水溶性薄膜。

　　Degradable film not only has the function and characteristics of traditional plastics, but also can be reused in the natural environment through microbial action in soil and water or ultraviolet radiation in sunlight after reaching the service life. Finally, it can be reunited into the ecological environment and returned to nature in the way of restoration. Domestic research and development of varieties have covered photodegradation, photobiodegradation, photooxidation biodegradation, high starch content biodegradation, high calcium carbonate filled photooxidation degradation, total biodegradation and so on. The most commonly used are edible and water-soluble films.

　　可食性薄膜

　　edible film

　　可食性包装膜，如壳聚糖可食性包装膜、玉米蛋白质包装膜、改性纤维素可食性包装膜及复合型可食性包装膜等，可以用于各种食品的内包装，如裹包糖果、黏性糕点的衬垫，或制成肠衣、果衣与胶囊等。它迎合了现代消费快捷便当的趋向，在食品行业中具有很大的市场。
                          

　　Edible packaging film, such as Chitosan Edible Packaging film, corn protein packaging film, modified cellulose edible packaging film and composite edible packaging film, can be used in the inner packaging of various foods, such as candy wrapped, sticky pastry pads, or made into intestinal coats, fruit coats and capsules. It caters to the fast and convenient trend of modern consumption and has a large market in the food industry.

　　近年来，世界各国在可食膜研讨上取得了很大停顿，可食膜的应用也越来越普遍，但目前可食膜还存在着加工性、机械性强度、维护功用性方面比塑料薄膜差、本钱高等缺乏之处。

　　In recent years, the world has made a great pause in the study of edible film, and the application of edible film is becoming more and more common. However, there are still some shortcomings of edible film in terms of processability, mechanical strength and maintenance function, which are worse than plastic film and higher cost.

　　水溶性薄膜

　　Water-soluble film

　　水溶性薄膜是指在常温下能溶解于水的薄膜，作为一种新颖的绿色包装材料，在欧美、日本等国被普遍用于各种产品的包装，例如农药、化肥、颜料、染料、清洁剂、水处置剂、矿物添加剂、洗濯剂、混凝土添加剂、摄影用化学试剂及园艺护理的化学试剂等。水溶性薄膜由于具有降解彻底、运用安全便当等环保特性，已遭到世界兴隆国度普遍注重，其中溶解性比较好的水溶性薄膜为聚氧化乙烯薄膜。

　　Water-soluble film is a kind of film that can dissolve in water at room temperature. As a novel green packaging material, it is widely used in the packaging of various products in Europe, America, Japan and other countries, such as pesticides, fertilizers, pigments, dyes, detergents, water disposal agents, mineral additives, detergents, concrete additives, photographic chemical reagents and horticultural care chemical reagents. Water-soluble film has attracted worldwide attention due to its environmental protection characteristics such as thorough degradation, safe and convenient use, among which the most soluble water-soluble film is polyethylene oxide film.

　　安徽康多亨生物环保科技有限公司消费的生物降解材料、全生物降解材料，可降解塑料袋、可降解渣滓袋，一次性降解刀叉勺，可降解薄膜，在土壤和自然环境快速降解，无毒、无公害、无异味，降解后不会破坏土质结构，真正做到“源于自然，还于自然”，是塑料、纸制包装的较好替代品。

　　Anhui Kangduoheng Bio-environmental Protection Technology Co., Ltd. consumes biodegradable materials, all-biodegradable materials, degradable plastic bags, degradable residue bags, disposable degradable knife and fork spoons, degradable film, rapid degradation in the soil and natural environment, non-toxic, non-polluting, non-peculiar smell, degradation will not damage the soil structure, truly achieve "from nature, but also from nature", is plastic. A good substitute for paper and material packaging.
