食品包装袋根据需要包装的产品自身特性需求来进行材质的选择，为什么这么说？下面济南订做食品包装袋厂家为您分析：

Why is it said that food packaging bags are made of materials based on the characteristics and needs of the products they need to be packaged? The manufacturer of customized food packaging bags in Jinan will analyze for you:

1.如果需要食品包装袋具有防潮，耐寒、低温热封拉力强的特性，可以选择BOPP/LLDPE两层复合材质。这种复合材质一般用于速食面，零食，冷冻点心等食品。

If you need food packaging bags to have the characteristics of moisture resistance, cold resistance, and strong low-temperature heat sealing force, you can choose BOPP/LLDPE two-layer composite material. This composite material is generally used for instant noodles, snacks, frozen Dim sum and other foods.

2.如果需要食品袋具有防潮，耐油，透明度高挺性好的特性，可以选择BOPP/CPP两层复合材质。这种复合材质一般用于饼干、糖果，及各类轻便食品。

If you need food bags with moisture resistance, oil resistance, high transparency, and good stiffness, you can choose BOPP/CPP two-layer composite material. This composite material is generally used for biscuits, candies, and various lightweight foods.

3.如果需要食品袋具有防潮，耐油，隔氧，遮光，挺性好的特性，可以选择BOPP/VMCPP两层复合材质。这种复合材质一般用于薯片这类油炸食品及各类干燥食品。

If you need food bags with the characteristics of moisture resistance, oil resistance, oxygen resistance, shading, and good stiffness, you can choose BOPP/VMCPP two-layer composite material. This composite material is generally used for fried foods such as potato chips and various dry foods.

4.如果需要食品袋具有防潮，隔氧，遮光的特性，可以选择BOPP/VMPET/LLDPE三层复合材质。这种复合材质适用于米制小吃、茶叶这类食品。

If you need food bags with moisture-proof, oxygen resistant, and light blocking characteristics, you can choose BOPP/VMPET/LLDPE three-layer composite material. This composite material is suitable for foods such as rice snacks and tea leaves.

5.如果需要食品袋具有防潮，隔氧，保香，耐高温的特性，可以选择PET/CPP两层复合材质。这种复合材质一般用于酒类食品、香味食品，及像冷冻包子这种需要蒸煮的食品。

If you need food bags with moisture-proof, oxygen resistant, fragrance preserving, and high-temperature resistance characteristics, you can choose PET/CPP two-layer composite material. This composite material is generally used for alcoholic foods, flavored foods, and foods such as frozen buns that require steaming.

6.如果需要食品袋具有防潮，耐高温，易封性的特性，可以选择PET/PET/CPP三层复合材质。这种复合材质一般用于酱油、醋等食品。

If you need food bags with moisture resistance, high temperature resistance, and easy sealing properties, you can choose PET/PET/CPP three-layer composite material. This composite material is generally used in foods such as soy sauce and vinegar.

常见的食品袋材质结构

Common food bag material structures

生活中常见的食品袋大多都是多种材质复合材质而成的复合材质袋，一般都分为三层结构。因PE、PP性高、热封性较好，通俗来讲就是易封口。所以里层一般都是PE或PP，外层是PA，中间根据产品的特性选择是EVOH、PVDC或镀铝膜

Most common food bags in daily life are composite bags made of multiple materials, usually divided into a three-layer structure. Due to the high safety and good heat sealing properties of PE and PP, they are generally easy to seal. So the inner layer is generally PE or PP, the outer layer is PA, and the middle layer is EVOH, PVDC or aluminized film according to the product characteristics

PVDC、EVOH阻隔性较好，放置在食品袋的中间能有效防止氧化。而镀铝膜的闭光性好，适用于不宜见光的特性。PA的印刷性较好，因此用在外层。

PVDC and EVOH have good barrier properties and can effectively prevent oxidation when placed in the middle of food bags. And the aluminum coating has good light closure and is suitable for properties that are not suitable for light exposure. PA has good printability, so it is used in the outer layer.

虽说食品袋多是多层材质复合材质制造而成的复合材质袋，但也有由单一材质制成的食品袋，如火腿肠的肠衣就是只应用了单一的PVDC制成的。更多相关内容就来我们网站http://www.scuhtg.com咨询！

Although food bags are mostly made of multi-layer composite materials, there are also food bags made of a single material, such as the casing of ham sausage, which is only made of a single PVDC. For more related content, come to our website http://www.scuhtg.com consulting service
