We can see vacuum food packaging bags everywhere. The selection and use of vacuum bags have their color requirements. Today, I will explain how to choose vacuum bags.

一、材料厚薄以及特殊属性材料的选择

1、 Material thickness and selection of materials with special properties

装不同的食品应该选用不同厚薄以及不同属性的真空袋的材料，装的产品重就要选择厚实的材料，装的产品轻就选择薄的材料节约成本。当然越厚的材料成本也就越高，但是也会越结实。不同的食品会有不同的属性，例如：盐焗食品的油性大要选择耐油分的材料，泡菜食品的盐份高要选择耐酸碱性的材料，需要经过高温或者高温蒸煮的产品要选择耐高温的材料。

The materials of vacuum bags with different thicknesses and properties should be selected for different foods. Thick materials should be selected for heavy products, and thin materials should be selected for light products to save costs. Of course, the thicker the material, the higher the cost, but also the stronger. Different foods have different properties. For example, the oil resistant materials should be selected for salt baked foods, the acid and alkaline resistant materials should be selected for pickle foods with high salt content, and the high-temperature resistant materials should be selected for products that need high-temperature disinfection or high-temperature cooking.

二、真空袋分为单层和多层

2、 The vacuum bag is divided into single layer and multi-layer

普通的真空袋为PE单层材料的，这样的袋子可以抽真空，但是抽真空的破损率和漏气率都比较高，但是成本低，有不少客户为了节约成本选择单层的PE袋作为真空袋使用。好的真空袋都是多层复合的材料制作的，例如：尼龙/PE，这个是二层复合的袋子，这样的袋子结实，抽真空不会漏气，目前大部分的食品包装袋都是选用多层复合袋作为抽真空的袋子。

Ordinary vacuum bags are made of PE single-layer materials. Such bags can be evacuated, but the damage rate and air leakage rate of vacuum are high, but the cost is low. Many customers choose single-layer PE bags as vacuum bags to save costs. Good vacuum bags are made of multi-layer composite materials, such as nylon / PE, which is a two-layer composite bag. Such bags are solid and will not leak when vacuumized. At present, most food packaging bags use multi-layer composite bags as vacuumized bags.

在制作包装袋的时候要清楚产品有什么特殊要求等，只有了解具体的详情才能定制出来符合产品的包装袋才能避免使用过程中问题的发生。

When making packaging bags, it is necessary to know what special requirements the products have. Only by understanding the specific details can we customize packaging bags that meet the requirements of the products and avoid problems in the use process.
