現在，在不少小飯店或露天美食攤點，為了預防共用餐具的不衛生，購物袋廠家往往會在飯碗上套一個生物降解塑料袋，這樣不僅衛生、節水，而且還可節省洗碗的人力成本。

Now, in many small restaurants or open-air food stalls, in order to prevent the unsanitary sharing of tableware, shopping bag manufacturers often put a biodegradable plastic bag on their rice bowl, which is not only hygienic and water-saving, but also saves the labor cost of washing dishes.

在生活中，我們很多人為了貪圖方便，省時省事，也會經常利用塑料背心袋包裝熟食，事實上，使用生物降解塑料袋并不代表就健康安全衛生了，如果使用不當，往往一時方便卻可能會給身體帶來永久的健康隱患。比如，利用聚氯乙烯材質制作的塑料背心袋因為含有塑化劑就不能用作熟食包裝。出口塑料袋塑化劑也稱增塑劑，在塑料制品加工中如果添加塑化劑，可以使產品柔韌性增強，變得易于加工。塑化劑被廣泛應用于塑料、橡膠、粘合劑、纖維素、樹脂、醫療器械、電纜等產品生產中。塑化劑的產品種類有百余種之多，普遍使用的是鄰苯二甲酸酯類的化合物。微量塑化劑對人體健康影響不大，但是，體內若攝入塑化劑過多，將會影響到人體內分泌、生殖功能以及身體的正常生長發育等。

In life, many of us often use plastic vest bags to pack cooked food in order to be convenient and save time and trouble. In fact, the use of biodegradable plastic bags does not mean health, safety and hygiene. If they are not used properly, they are often convenient for a while, but they may bring permanent health hazards to the body. For example, plastic vest bags made of PVC can not be used as cooked food packaging because they contain plasticizer. Plasticizer for export plastic bags is also called plasticizer. If plasticizer is added in the processing of plastic products, the flexibility of products can be enhanced and easy to process. Plasticizers are widely used in the production of plastics, rubber, adhesives, cellulose, resins, medical devices, cables and other products. There are more than 100 kinds of plasticizers, and phthalate esters are widely used. Micro plasticizer has little effect on human health, but if the body takes too much plasticizer, it will affect human endocrine, reproductive function and normal growth and development of the body.

日常生活中常見的生物降解塑料袋既有聚乙烯材質的，也有聚氯乙烯材質的。利用聚乙烯材質制作的食品級的塑料背心袋可以用來包裝低溫熟食，而聚氯乙烯材質的生物降解塑料袋，在加工時，由于添加了大量的增塑劑和穩定劑，若用來包裝熟食，塑料中所添加的增塑劑等不利于人體健康的有害成分就會溶解或揮發出來，對所包裝食物造成污染，可見，食用味美的方便美食，有選擇地使用健康安全的塑料背心袋，做好塑化劑的預防是多么地重要。

Biodegradable plastic bags commonly used in daily life are made of both polyethylene and polyvinyl chloride. The food grade plastic vest bag made of polyethylene can be used to package low-temperature cooked food, while the biodegradable plastic bag made of polyvinyl chloride will dissolve or volatilize if it is used to package cooked food due to the addition of a large number of plasticizers and stabilizers, It pollutes the packaged food. It can be seen how important it is to eat delicious and convenient food, selectively use healthy and safe plastic vest bags, and prevent plasticizers.

在，人們用生物降解塑料袋盛裝食物已習以為常，事實上，不是所有的生物降解塑料袋都可用來盛裝食物的。通常使用的生物降解塑料袋的制作材質有如下幾種：高壓聚乙烯、低壓聚乙烯、聚丙烯、聚氯乙烯以及再生材料等。高壓聚乙烯塑料袋可用作糕點、糖果、炒貨、餅干、奶粉、鹽、茶葉等食品包裝以及纖維品和日化用品包裝；低壓聚乙烯塑料袋通常用作保鮮袋、方便袋、購物袋、手提袋、背心袋以及垃圾袋、菌種袋等，而不用于熟食包裝；聚丙烯塑料袋主要用于包裝紡織品、針棉品、服裝、襯衫等，也不能用于熟食包裝；聚氯乙烯塑料袋多用于箱包、針棉品包裝、化妝品包裝等，更不能使用于熟食包裝。

In, people are used to holding food in biodegradable plastic bags. In fact, not all biodegradable plastic bags can be used to hold food. The commonly used biodegradable plastic bags are made of the following materials: high pressure polyethylene, low pressure polyethylene, polypropylene, polyvinyl chloride and recycled materials. High pressure polyethylene plastic bags can be used for food packaging such as cakes, candy, fried goods, biscuits, milk powder, salt and tea, as well as fiber and daily chemical products; Low pressure polyethylene plastic bags are usually used as fresh-keeping bags, convenience bags, shopping bags, handbags, vest bags, garbage bags, strain bags, etc., rather than cooked food packaging; Polypropylene plastic bags are mainly used for packaging textiles, cotton products, clothing, shirts, etc., and can not be used for cooked food packaging; PVC plastic bags are mostly used for luggage, needle cotton products packaging, cosmetics packaging, etc., and can not be used for cooked food packaging.

市場上通行的塑料袋除了以上四種以外，利用再生材料生產的五顏六色市場方便袋也非常多，用再生材料制作的塑料袋盡管看起來鮮艷好看，由于是使用廢舊塑料的回收料制作，更不能用來包裝食品。

In addition to the above four kinds of plastic bags commonly used in the market, there are also many colorful market convenience bags made of recycled materials. Although the plastic bags made of recycled materials look bright and beautiful, they can not be used to package food because they are made of recycled waste plastics.

消費者在日常生活中，使用生物降解塑料袋包裝熟食時，除了不用容易辨別的鮮艷的再生塑料袋以外，其他不易辨別的一定要看塑料背心袋的外觀是否印有“食品用”的標志，通常這個標志應該在包裝袋正面的比較醒目的位置。

In daily life, when consumers use biodegradable plastic bags to package cooked food, in addition to the bright recycled plastic bags that are not easy to identify, other things that are not easy to identify must depend on whether the appearance of the plastic vest bag is printed with the sign of "for food". Usually, this sign should be in a more eye-catching position on the front of the packaging bag.
