“”這一詞如今已經(jīng)成為人們生活長談闊論的詞語,所以隨著人們生活質(zhì)量的不斷提高,對(duì)生活質(zhì)量的要求也越來越高,環(huán)境問題的重視已經(jīng)非常重要。在塑料袋行業(yè)內(nèi),塑料袋廠家樂億也努力于綠色塑料袋的生產(chǎn)。那么什么樣的塑料袋才能被成為塑料袋呢?
The word "environmental protection" has become a long talk in people's life. Therefore, with the continuous improvement of people's quality of life, the requirements for the quality of life are becoming higher and higher, and the attention to environmental problems has been very important. In the plastic bag industry, the plastic bag factory jialeyi also strives to produce green plastic bags. So what kind of plastic bags can be made into environmentally friendly plastic bags?
 
一、 符合標(biāo)準(zhǔn)8的塑料袋叫塑料袋,塑料袋中又包括再次利用塑料袋和新料塑料袋。生產(chǎn)塑料袋過程中添加了降解母料的塑料袋叫降解塑料袋,降解塑料袋90天后在符合一定的條件下可以自動(dòng)降解。以塑料薄膜為原料制作的袋子統(tǒng)稱塑料袋。
 
1、 The plastic bags that meet the national standard 8 are called environmental protection plastic bags, which include reuse plastic bags and new material plastic bags. The plastic bag added with degradable masterbatch in the production of plastic bag is called degradable plastic bag. After 90 days, the degradable plastic bag can be degraded automatically under certain conditions. Bags made of plastic film are collectively referred to as plastic bags.

二、 一種經(jīng)過日光照射、遇潮濕可很快溶化的塑料袋。經(jīng)產(chǎn)品質(zhì)量監(jiān)督檢驗(yàn)站檢測(cè),產(chǎn)品指標(biāo)全部達(dá)到或超過規(guī)定質(zhì)量標(biāo)準(zhǔn),具有衛(wèi)生的特點(diǎn),這種可降解塑料袋,采用聚烯烴樹脂,添加降解劑等原料生產(chǎn)。
 
2、 The utility model relates to a plastic bag which can be quickly dissolved in sunlight and moisture. According to the inspection of environmental protection product quality supervision and inspection station, all product indexes meet or exceed the national quality standards, and have the characteristics of sanitation. This degradable plastic bag is produced by polyolefin resin, adding degradant and other raw materials.
 
三、用完后可進(jìn)行二次回收后再造的塑料袋。
 
3、 A plastic bag that can be recycled after secondary recycling.
 
在塑料包裝制品的生產(chǎn)過程中加入一定量的添加劑(如淀粉、改性淀粉或其它纖維素、生物降解劑等),使塑料包裝物較容易在自然環(huán)境中降解。試驗(yàn)表明,大多數(shù)可降解塑料在一般環(huán)境中暴露3個(gè)月后逐漸裂成碎片。如果這些碎片被埋在垃圾或土壤里,則降解效果不明顯。使用可降解塑料有四個(gè)不足:一是多消耗糧食;二是使用可降解塑料制品仍不能完全解決“視覺污染”;三是由于技術(shù)方面的原,使用可降解塑料制品不能完全解決對(duì)環(huán)境的“潛在危害”;四是可降解塑料由于含有特殊的添加劑而難以回收利。
 
In the production process of plastic packaging products, a certain amount of additives (such as starch, modified starch or other cellulose, biodegradable agents, etc.) are added to make the plastic packaging easier to degrade in the natural environment. The test shows that most degradable plastics gradually break into fragments after exposure to general environment for 3 months. If these fragments are buried in garbage or soil, the degradation effect is not obvious. The use of degradable plastics has four shortcomings: first, it consumes more food; Second, the use of degradable plastic products can not completely solve the "visual pollution"; Third, due to the original technology, the use of degradable plastic products can not completely solve the "potential harm" to the environment; Fourth, degradable plastics are difficult to recover because they contain special additives.
