商家在包裝商品時，一般都會為商品選購一款靚麗的塑料袋。不過，你們知道這些塑料袋的質量如何？相信很多外行的人是看不出的。今天濟南塑料袋小編告訴大家：選購塑料袋時要看看這五方面是否合格。

When packaging goods, businesses usually buy a beautiful plastic bag for the goods. However, do you know the quality of these plastic bags? I believe many laymen can't see it. Today, a small editor of plastic bags in Jinan told us that when you buy plastic bags, you should see whether these five aspects are qualified.

一，塑料袋外包裝要有生產廠家標志。正規的塑料袋生產廠家都會在外包裝袋上標明生產廠家的的名字、廠址、產品企業全稱。這樣的作用就是一旦塑料袋出現質量問題，可以很容易就追溯到生產廠家。如果你選購的塑料袋并沒有標明生產廠家的話，建議還是謹慎使用。

1、 The outer package of the plastic bag shall have the manufacturer's mark. Regular plastic bag manufacturers will mark the name, address and full name of the manufacturer on the outer packaging bag. This function is that once the plastic bag has a quality problem, it can be easily traced back to the manufacturer. If the plastic bag you buy is not marked with the manufacturer, it is recommended to use it cautiously.

二，塑料袋出廠時應該是無異嗅、無異味的。但有些不良廠家為了節省成本，利用廢舊材料來生產。這些廢舊材料生產的包裝袋一般都會散發出一種刺激性的味道，很容易對包裝品進行二次污染。因此，我們應該盡量選購沒有異味的塑料袋。

2、 The plastic bag should be odorless and odorless when leaving the factory. However, some defective manufacturers use waste materials to produce in order to save costs. The packaging bags made of these waste materials will generally give off an irritating taste, which is easy to cause secondary pollution to the packaging products. Therefore, we should try to buy plastic bags without odor.

三，在包裝性能允許的情況下，應該盡量選擇厚度更小的包裝袋。為什么？首先，更薄的包裝袋單個價格更低，可以為您節省包裝成本；其次，輕薄的包裝袋更容易降解，可以減少對環境造成污染，畢竟輕薄的塑料袋更符合綠色環保包裝的理念。

3、 If the packaging performance allows, the packaging bag with smaller thickness should be selected as far as possible. Why? First of all, the single price of thinner packaging bags is lower, which can save you packaging costs; Secondly, thin and light packaging bags are easier to degrade, which can reduce environmental pollution. After all, thin and light plastic bags are more in line with the concept of green packaging.

四，好的塑料袋價錢一般都不會便宜。由于質量好的塑料袋都是使用全新材料來制造的，成本比較高，所以其售價一般都不會低。但是一分錢一分貨，這些包裝袋的質量都是很好地。價錢很低的塑料袋基本上都是用舊料生產，質量沒保障，更不適用于食品的直接包裝。至于怎么選擇，還是看您的包裝需求。

4、 Good plastic bags are generally not cheap. Because high-quality plastic bags are made of new materials, and the cost is relatively high, their prices are generally not low. However, the quality of these bags is very good. The plastic bags with very low prices are basically produced with old materials, and the quality is not guaranteed, not to mention the direct packaging of food. As for the choice, it depends on your packaging needs.

五，盡量選擇不加涂、鍍層材料的包裝袋。很多塑料袋為了獲得加美觀、耐蝕的特性，常常會使用附帶鍍層的材料。但是這不只給產品報廢后的材料回收、再利用帶來了困難，還因為大部分涂料本身就具有毒性，要是人們食用了這些包裝的食品，都對人們身體產生或多或少的危害。而且，涂、鍍工藝過程中也為周邊環境帶來了大的污染。如涂料揮發毒性溶劑氣體，電鍍時產生含鉻等重金屬的廢液、廢渣污染等。因此，應盡可能選用不加涂、鍍層的包裝材料生產的包裝袋。

5、 Try to choose the packaging bag without coating and plating materials. Many plastic bags often use materials with coatings in order to obtain beautiful and corrosion resistant properties. But this not only makes it difficult to recycle and reuse the discarded materials, but also because most of the coatings themselves are toxic. If people eat these packaged foods, they will do more or less harm to people's health. In addition, the coating and plating process also brings great pollution to the surrounding environment. Such as volatile toxic solvent gas of paint, waste liquid and residue pollution of chromium and other heavy metals during electroplating. Therefore, packaging bags made of packaging materials without coating or plating should be selected as far as possible.
