真空包装袋得用除氧的原理有效地防止食品变质,保持其色、香、味及营养价值。在食品行业得到广泛的应用。食品真空包装材料的安全性,直接影响着食品的安全。在进行真空包装时,选择好的包装材料是确保食品安全与否的关键。那么,食品真空包装袋材质的安全如何鉴别?

The vacuum packaging bag can effectively prevent the deterioration of food and maintain its color, aroma, taste and nutritional value by using the principle of deaeration. It is widely used in the food industry. The safety of food vacuum packaging materials directly affects the safety of food. In vacuum packaging, the choice of good packaging materials is the key to ensure food safety. So, how to identify the safety of food vacuum packaging bag materials?

专业人士介绍说,不是专业的人士有可能是区分不出的,但是具有毒性,添加了少量再生料的袋子作食品袋,对人身体是有害的,应慎重。现在介绍几种简单辨别食品真空包装袋材质的技巧。

Professionals said that non professionals may not be able to distinguish them, but they are toxic. Bags with a small amount of recycled materials added as food bags are harmful to people's health and should be cautious. Now I will introduce some simple techniques for identifying the material of food vacuum packaging bags.


一、看颜色

1、 Look at the color

无毒的聚乙烯塑料为乳白色、半透明体,手摸有石蜡滑腻感,质地柔软能弯曲。放在水中能浮于水面,沸水中显着软化。

The non-toxic polyethylene plastic is milky white and translucent. It feels waxy when touched by hand. It is soft and flexible. It can float on the water surface and soften significantly in boiling water.

二、闻气味

2、 Smell

无毒的聚乙烯塑料遇火容易燃烧,燃烧时滴下蜡状物,膨胀,并有石油气味。火焰为黄色,下端为蓝色,少量黑烟。离开火后仍继续燃烧。

The non-toxic polyethylene plastic is easy to burn in case of fire. When burning, wax will drop, expand and have oil smell. The flame is yellow, the lower end is blue, and a small amount of black smoke. It continued to burn after leaving the fire.

有毒的聚氯乙烯塑料透明度不及聚乙烯,手摸有发黏的感觉,质地柔软富有弹性,遇冷变硬。放在水中下沉。不容易燃烧,燃烧时软化、能拉丝,并有刺鼻的辛辣味。火焰*为黄色,下端为绿色,冒黑烟。离开火后慢慢熄灭。

Toxic polyvinyl chloride plastic is less transparent than polyethylene. It feels sticky when touched by hand. It is soft and elastic and becomes hard when cold. Sink in the water. It is not easy to burn. It softens when burning, can be brushed, and has a pungent and spicy taste. The flame * is yellow, and the lower end is green, emitting black smoke. Go out slowly after leaving the fire.

三、看拉力

3、 Look at the tension

新料加工的真空包装袋强度和韧性高,再生料的真空包装袋,拉力强度、韧性等特点就会变得比价差。

The strength and toughness of vacuum packaging bags processed with new materials are high, and the tensile strength and toughness of vacuum packaging bags of recycled materials will become price difference.
