How many materials are used for packaging bags of small grain food?

Small grains such as sorghum, buckwheat, oats, mung beans, adzuki beans, fava beans, peas, black beans, etc. are rich in nutrients and serve as both traditional food and health food resources. With the improvement of people's living standards and changes in dietary structure, small grains, as a new type of food resource that combines medicine and food, play an important role in modern green health food. The performance of food packaging materials directly affects the storage life and taste changes of food. Choosing good packaging materials is the key to successful packaging. How many materials are there for packaging bags of small grain food?
There are usually six types of packaging materials for small grain food:
1. PVDC (Polyvinylidene Chloride): It has good airtightness, is safe and environmentally friendly, meets food hygiene requirements, and is widely used in food packaging. Moreover, PVDC has good weather resistance and will not fade even after prolonged outdoor exposure.
2. PE (polyethylene): It has good chemical stability, high transparency, and can withstand corrosion from most acids and bases. It can be used for food packaging. In addition, it has good low temperature resistance.
3. PA (Nylon): PA material has good puncture resistance and oxygen barrier properties, and is usually used for food packaging.
4. PP (polypropylene): It is a packaging material that can be heated in a microwave oven and is commonly used in food bags.
5. EVOH (ethylene/vinyl alcohol copolymer): Wear resistant, strong stretchability, and high surface strength.
6. Aluminum coated film (aluminum+PE): It is an environmentally friendly material that can prevent food oxidation and spoilage, avoid environmental pollution, and maintain the freshness and taste of food.
