商家在包装商品时，一般都会为商品选购一款靓丽的方便袋。不过，你们知道这些方便袋的质量如何？相信很多外行的人是看不出的。今天小编告诉大家：选购济南方便袋时要注意什么。

When packaging goods, merchants usually buy a beautiful convenient bag for the goods. However, do you know the quality of these convenience bags? I believe many laymen can't see it. Today, the editor told you what to pay attention to when purchasing Jinan convenience bags.

一，方便袋外包装要有生产厂家标志。正规的方便袋生产厂家都会在外包装袋上标明生产厂家的的名字、厂址、产品企业全称。这样的作用就是一旦方便袋出现质量问题，可以很容易就追溯到生产厂家。如果你选购的方便袋并没有标明生产厂家的话，建议还是谨慎使用。

1、 The outer packaging of the convenience bag shall have the manufacturer's logo. Formal convenience bag manufacturers will mark the name, address and full name of the manufacturer on the outer packaging bag. This function is that once the quality problem of the convenience bag occurs, it can be easily traced back to the manufacturer. If the convenience bag you choose does not indicate the manufacturer, it is recommended to use it with caution.

二，方便袋出厂时应该是无异嗅、无异味的。但有些不良厂家为了节省成本，利用废旧材料来生产。这些废旧材料生产的包装袋一般都会散发出一种刺激性的味道，很容易对包装品进行二次污染。因此，我们应该尽量选购没有异味的方便袋。

2、 The convenience bag should be odorless and odorless when leaving the factory. However, in order to save costs, some poor manufacturers use waste materials to produce. The packaging bags produced by these waste materials generally emit a pungent smell, which is easy to cause secondary pollution to the packaging. Therefore, we should try to buy convenience bags without peculiar smell.

三，在包装性能允许的情况下，应该尽量选择厚度更小的包装袋。为什么？，更薄的包装袋单个更低，可以为您节省包装成本；其次，轻薄的包装袋更容易降解，可以减少对环境造成污染，毕竟轻薄的方便袋更符合绿色包装的理念。

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

四，好的方便袋价钱一般都不会便宜。由于质量好的方便袋都是使用全新材料来制造的，成本比较高，所以其售价一般都不会低。但是一分钱一分货，这些包装袋的质量都是很好地。价钱很低的方便袋基本上都是用旧料生产，质量没保障，更不适用于食品的直接包装。于怎么选择，还是看您的包装需求。

4、 The price of a good convenience bag is generally not cheap. Because the convenience bags with good quality are made of brand new materials and the cost is relatively high, their prices are generally not low. But the quality of these bags is very good. The cheap convenience bags are basically made of old materials, and the quality is not guaranteed, and they are not suitable for direct packaging of food. The choice depends on your packaging requirements.

五，尽量选择不加涂、镀层材料的包装袋。很多方便袋为了获得加美观、耐蚀的特性，常常会使用附带镀层的材料。但是这不只给产品报废后的材料回收、再利用带来了困难，还因为大部分涂料本身就具有毒性，要是人们食用了这些包装的食品，都对人们身体产生或多或少的危害。而且，涂、镀工艺过程中也为周边环境带来了大的污染。如涂料挥发毒性溶剂气体，电镀时产生含铬等重金属的废液、废渣污染等。因此，应尽可能选用不加涂、镀层的包装材料生产的包装袋。

5、 Try to choose packaging bags without coating and coating materials. In order to obtain more beautiful and corrosion resistant properties, many convenience bags often use materials with coating. But this not only makes it difficult to recycle and reuse the materials after the products are scrapped, but also because most of the coatings themselves are toxic. If people eat these packaged foods, they will cause more or less harm to people's health. In addition, the process of coating and plating also brings great pollution to the surrounding environment. For example, toxic solvent gas is volatilized from the coating, and waste liquid containing chromium and other heavy metals and waste residue pollution are produced during electroplating. Therefore, packaging bags produced by packaging materials without coating and coating should be selected as far as possible.
