如果是包裝食品，首先選擇的是包裝袋的安全性，有異味，有污染可能的包裝袋一定不要選。另外，包裝袋對(duì)物品的作用主要是保護(hù)，即使沒污染，但是機(jī)械性能低的包裝袋也不能選用。有的包裝袋就是這樣，用一個(gè)非常干凈、無異味的包裝袋盛著饅頭往前走，走著走著，那饅頭就掉出來了，沾上了好多土，沒法吃了。這種塑料包裝袋不管多么干凈也是沒法用的。
If they are packaged foods, first choose the safety of the packaging, is faulty, have the packing bag of pollution may don't choose.

Some packaging is like this, with a very clean, no smell the packing bag of the steamed bread are walking, walking, the steamed bread will fall out, with a lot of soil, can't eat. The plastic bag is no way to use no matter how clean it.

真空包裝袋的好壞首先在于它的功能是否能達(dá)到目標(biāo)，其次是它對(duì)食品有沒有污染。
The stand or fall of vacuum packing bag first lies in its function whether can reach the goal, the second is that it did on food contamination.
