1、在食物包裝職業(yè)中常用的真空包裝袋就能夠有用隔氧，防止食物發(fā)作腐爛變質(zhì)，有用延伸其保質(zhì)期，并阻撓細*的侵入和繁衍，確保食物的衛(wèi)生。

1. The vacuum packaging bag commonly used in the food packaging industry can effectively isolate oxygen, prevent food from rotting and deteriorating, extend its shelf life, prevent the invasion and reproduction of fine food, and ensure the hygiene of food.

 

2、塑料包裝袋的防潮性、阻隔性、加工成型性等都較為突，且成本相對賤價。

 

2. The moisture-proof, barrier and processing formability of plastic packaging bags are relatively prominent, and the cost is relatively cheap.

 

3、在產(chǎn)品的貯存運送過程中，塑料包裝袋能夠有用防止產(chǎn)品的滲漏、散落、損耗、縮短、變色等。

 

3. During the storage and transportation of products, plastic packaging bags can effectively prevent the leakage, scattering, loss, shortening and discoloration of products.

 

4、與金屬、陶瓷、玻璃等傳統(tǒng)塑料包裝袋資料比較，塑料包裝袋的輕便性是其他資料無法比擬的。

 

4. Compared with metal, ceramic, glass and other traditional plastic bags, the portability of plastic bags is unmatched by other materials.

在塑料包裝袋定做時，也可以生產(chǎn)出多種顏色的產(chǎn)品，但是在使用有色塑料袋的時候，需要注意存在的一些問題。

 

When the plastic packaging bag is customized, it can also produce a variety of color products, but when using colored plastic bags, we need to pay attention to some problems.

 

有色塑料袋可能是回收處理的，盡管這些塑料袋在加工之前，都經(jīng)過了洗滌、粉碎等程序，但它們在被回收之前裝過什么東西我們卻不知道。它們以前也有可能裝過有害物質(zhì)，不可能憑著洗滌就能簡單的除掉這些有害物質(zhì)。所以許多人會用五顏六色的塑料袋，從菜市場或農(nóng)貿(mào)市場帶回青菜、水果，甚用有色塑料袋來裝早點或燒烤的雞翅、油餅等食品，這些都是需要注意的。

 

Colored plastic bags may be recycled. Although these plastic bags go through washing, crushing and other procedures before processing, we don't know what they contain before being recycled. They may have contained harmful substances before, and it is impossible to simply remove these harmful substances by washing. Therefore, many people will use colorful plastic bags to bring back green vegetables and fruits from the vegetable market or farmers' market, and even use colored plastic bags to hold breakfast or barbecue chicken wings, oil cakes and other food. These all need attention.

 

所以盡量還是使用白色或無色透明的塑料袋，更加提倡使用菜籃子或自己攜帶的食品塑料袋，避免對人體產(chǎn)生危害。

 

Therefore, try to use white or colorless transparent plastic bags, and more advocate the use of vegetable baskets or their own food plastic bags to avoid harm to human body.
