食品包裝袋根據需要包裝的產品自身特性需求來進行材質的選擇，為什么這么說？下面濟南訂做食品包裝袋廠家為您分析：

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.如果需要食品包裝袋具有防潮，耐寒、低溫熱封拉力強的特性，可以選擇BOPP/LLDPE兩層復合材質。這種復合材質一般用于速食面，零食，冷凍點心等食品。

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，可以選擇BOPP/CPP兩層復合材質。這種復合材質一般用于餅干、糖果，及各類輕便食品。

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，可以選擇BOPP/VMCPP兩層復合材質。這種復合材質一般用于薯片這類油炸食品及各類干燥食品。

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，可以選擇BOPP/VMPET/LLDPE三層復合材質。這種復合材質適用于米制小吃、茶葉這類食品。

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，耐高溫的特性，可以選擇PET/CPP兩層復合材質。這種復合材質一般用于酒類食品、香味食品，及像冷凍包子這種需要蒸煮的食品。

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，耐高溫，易封性的特性，可以選擇PET/PET/CPP三層復合材質。這種復合材質一般用于醬油、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.

常見的食品袋材質結構

Common food bag material structures

生活中常見的食品袋大多都是多種材質復合材質而成的復合材質袋，一般都分為三層結構。因PE、PP性高、熱封性較好，通俗來講就是易封口。所以里層一般都是PE或PP，外層是PA，中間根據產品的特性選擇是EVOH、PVDC或鍍鋁膜

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阻隔性較好，放置在食品袋的中間能有效防止氧化。而鍍鋁膜的閉光性好，適用于不宜見光的特性。PA的印刷性較好，因此用在外層。

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.

雖說食品袋多是多層材質復合材質制造而成的復合材質袋，但也有由單一材質制成的食品袋，如火腿腸的腸衣就是只應用了單一的PVDC制成的。更多相關內容就來我們網站http://www.krakren.com咨詢！

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.krakren.com consulting service
