Jinan self sealed bags are simple and convenient, and are now widely used in food and other industries. But how to identify whether self sealed bags are non-toxic? Follow the manufacturer to have a look!
一、用眼睛观察法
1、 Eye observation
无毒塑料袋呈白色,透明或微透明,质地均匀;有毒自封口袋则为彩色或虽为白色,但透明度差,较浑浊,塑料表面拉伸不均匀,有小颗粒。
The non-toxic plastic bag is white, transparent or slightly transparent, and the texture is uniform; The toxic self sealing bag is colored or white, but it has poor transparency and turbidity. The plastic surface is stretched unevenly and has small particles.
二、用耳朵听
2、 Listen with your ears
用手使劲抖动塑料袋时,发出清脆声表明是无毒塑料袋;而声音小而闷的便是有毒塑料袋。
When shaking the plastic bag with your hands, a clear sound indicates that it is a non-toxic plastic bag; And the sound is small and stuffy is toxic plastic bags.
三、用手摸
3、 Touch
用手抚摸自封口袋表面,很光滑是无毒的;发粘、发涩、有蜡状感的是有毒的。
Touch the surface of the self sealing pocket with your hand, which is smooth and non-toxic; Sticky, astringent and waxy are poisonous.

4、 Smell with your nose
无毒的自封口袋是无味的;有刺激气味或味道不正常的是有毒的。

五、沉水试验法

把塑料袋放到水里,用手将其按到水底,稍等片刻,自封口袋,浮出水面的即为无毒自封口袋,沉在水底的即是有毒塑料包装袋。

六、燃烧法无毒的自封口袋易燃
