Flexible packaging refers to packaging materials with certain flexibility, elasticity and compressibility, usually made of multi-layer film through a composite process, with a certain degree of flexibility and deformability. Flexible packaging can be used to load liquid, powder, solid and other commodities, widely used in food, medicine, daily chemical and other industries.

Second, the advantages of flexible packaging

Compared with hard packaging, flexible packaging has many advantages:

1. Light weight: Flexible packaging is usually made of multi-layer film and has the characteristics of lightweight, which makes it easier to be carried and transported.

2. Good flexibility: Flexible packaging can be easily deformed and folded, which is more suitable for a variety of complex shapes of goods.

3. Heat resistance and cold resistance: Flexible packaging has good thermal insulation, thermal insulation and other properties, which can ensure the quality and safety of goods during storage and transportation.

4. Moisture-proof and moisture-proof: the material of flexible packaging is usually a composite material with good moisture-proof performance, which can protect the goods from the influence of moisture.

5. Health protection: Flexible packaging generally has good sealing performance, which can prevent bacteria, viruses and other microorganisms from entering the packaging and ensure the health and safety of goods.

Third, the common types of flexible packaging

1. Plastic film bag: This is a common form of flexible packaging, widely used in food, medicine, daily chemical and other industries.

2. Aluminum foil packaging bag: In addition to the characteristics of plastic bags, this packaging can better protect the goods and extend the shelf life of the goods because the entire packaging is aluminum foil material.

3. Paper-plastic composite bag: This bag combines the characteristics of paper and plastic, which meets the requirements of environmental protection and has better moisture-proof and shock-proof function, and is more suitable for the packaging of industrial products.

4. Beverage packaging: Flexible packaging can also be used for the packaging of beverages and other liquid goods, made of plastic film and aluminum foil materials, with good heat resistance and preservation performance.

In short, flexible packaging is a flexible form of packaging that can adapt to various shapes of goods and is widely used in all aspects of life.
