八邊封食品包裝袋在我們的生活中是非常普遍的，所以今天東光縣立新塑料包裝有限公司簡短地談了八邊封食品包裝袋的特點。與傳統普通塑料袋相比，八邊封食品包裝袋的特點有以下幾點：

Octagonal sealed food packaging bags are very common in our life, so today Dongguang County Lixin plastic packaging Co., Ltd. briefly talked about the characteristics of octagonal sealed food packaging bags. Compared with traditional ordinary plastic bags, the characteristics of octagonal sealed food packaging bags are as follows:

1、抗拉強度大；

1. High tensile strength;

2、耐溶劑、耐油、熱封；

2. Solvent resistance, oil resistance and heat sealing;

3、空氣阻力影響小，滲透系數低；

3. The influence of air resistance is small and the permeability coefficient is low;

4、可加裝八面封平底袋扣或自粘袋；

4. It can be equipped with eight side sealed flat bottom bag buckle or self-adhesive bag;

5、無污染；溶于水；

5. Non toxic and pollution-free; Soluble in water;

6、抗靜電性能好，不易沾染灰塵；

6. Good antistatic performance, not easy to be contaminated with dust;

7、手感好，八面密封平底袋柔軟。

7. Good hand feel, eight sided sealed flat bottom bag is soft.

真空包裝袋得用除氧的原理有效地防止食品變質，保持其色、香、味及營養價值。在食品行業得到廣泛的應用。食品真空包裝材料的性，直接影響著食品的。在進行真空包裝時，選擇好的包裝材料是確保食品與否的關鍵。那么，食品真空包裝袋材質的如何鑒別？

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?

人士介紹說，不是的人士有可能是區分不出的，但是具有毒性，添加了少量再生料的袋子作食品袋，對人身體是有害的，應慎重。現在介紹幾種簡單辨別食品真空包裝袋材質的技巧。

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、看顏色

1、 Look at the color

的聚乙烯塑料為乳白色、半透明體，手摸有石蠟滑膩感，質地柔軟能彎曲。放在水中能浮于水面，沸水中顯著軟化。

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、聞氣味

2、 Smell

的聚乙烯塑料遇火容易燃燒，燃燒時滴下蠟狀物，膨脹，并有石油氣味。火焰為黃色，下端為藍色，少量黑煙。離開火后仍繼續燃燒。

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，手摸有發黏的感覺，質地柔軟富有彈性，遇冷變硬。放在水中下沉。不容易燃燒，燃燒時軟化、能拉絲，并有刺鼻的辛辣味。火焰*為黃色，下端為綠色，冒黑煙。離開火后慢慢熄滅。

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

新料加工的真空包裝袋強度和韌性高，再生料的真空包裝袋，拉力強度、韌性等特點就會變得比價差。

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.
