如何才能正確選擇食品塑料袋呢?

一,食品用塑料包裝袋出廠時(shí)是無異嗅、無異味的;有特殊氣味的塑料包裝袋,不能用于盛裝食品。

1、 Plastic packaging bags for food are odorless and odorless when they leave the factory; Plastic packaging bags with special odors cannot be used to contain food.

二,有顏色的塑料包裝袋(當(dāng)前市場(chǎng)上用的暗紅或黑等色)不能用于食品用塑料袋。因?yàn)檫@類塑料包裝袋往往是用廢舊回收再生塑料制作的。

2、 Colored plastic packaging bags (such as dark red or black currently used in the market) cannot be used for food plastic bags. Because these types of plastic packaging bags are often made from recycled plastic waste.

三,選購(gòu)食品用塑料袋到大購(gòu)買,不要到街頭小攤?cè)ベI,貨源沒有保障。

3、 It is best to buy plastic bags for food at large shopping malls instead of street stalls, as there is no guarantee of supply.

四,劣質(zhì)塑料袋在制作上,由于材料本身含有各種輔助劑、染料、重金屬,一旦裝入剛出鍋的食品,如包子、湯面等熱的食品,在溫度的促進(jìn)下,會(huì)導(dǎo)致袋中的有害物質(zhì)遷移到食品中。這些再生塑料含有嚴(yán)重超標(biāo)的致病菌和致癌物,食用這種塑料袋盛裝過的食品,塑料袋中的有害物質(zhì)就會(huì)遷移到人體,危害健康。

4、 In the production of low-quality plastic bags, because the materials themselves contain various auxiliaries, dyes, heavy metals, once the food is loaded into the hot food, such as steamed stuffed buns, Noodles in soup, etc., under the promotion of temperature, the harmful substances in the bags will migrate to the food. These recycled plastics contain severely excessive levels of pathogenic bacteria and carcinogens. When food is consumed in these plastic bags, the harmful substances in the bags will migrate to the human body, posing a threat to health.
