食品包裝袋產生異味的幾種形式：一是樹脂本身各類添加劑和自身的低分子物質；二是薄膜加工中產生的異味；三是軟包裝加工中出現的異味；四是儲存中產生的異味。

軟包裝加工中出現的異味”是指使用油墨、粘合劑、溶劑時的殘留溶劑或單體的味道。

"Peculiar smell" in flexible packaging processing refers to the smell of residual solvents or monomers when using inks, adhesives and solvents.

異味指產品長期在有氣味的環境下放置，刺激性分子會吸附在表面造成一些特殊的味道。在運輸途中也是同樣的道理。儲存溫度要低于35度，否則低分子的物質會快速遷移出來，造成味道升打開包裝食品時所聞到的異味的來源也可分為三種情況，一是內容物自身發生了明顯的變質，其外觀與味道均發生了明顯的變化。此種情況在熟肉的包裝制品中比較常見；二是包裝袋本身有各種異味，此種情況在種類干燥食品包裝中比較常見。第三種情況是上述兩種情況的綜合體，即：既有包裝材料本身的異味，同時內容物也發生了某種程度的變質。此種情況在油炸類食品包裝中比較常見。包裝的食品是否已發生了變質，相信讀者與消費者都會有自己的判斷但在實踐當中。選擇材質好的食品包裝袋能夠的食品。

Peculiar smell refers to that when the product is placed in an odorous environment for a long time, irritant molecules will adsorb on the surface and cause some special flavor. The same is true during transportation. The storage temperature should be lower than 35 degrees, otherwise low molecular substances will migrate out quickly, causing the taste to rise. The sources of the peculiar smell smelled when opening the packaged food can also be divided into three situations. First, the contents themselves have deteriorated significantly, and their appearance and taste have changed significantly. This situation is common in cooked meat packaging products; Second, the packaging bag itself has various peculiar smell, which is common in the packaging of dry foods. The third situation is the combination of the above two situations, that is, the peculiar smell of the packaging material itself and the deterioration of the contents to some extent. This situation is common in fried food packaging. Whether the packaged food has deteriorated, I believe readers and consumers will have their own judgment, but in practice. Choosing food packaging bags with good materials can improve food safety.
