Thermoplastic films have many significant advantages in the packaging field. Firstly, it has good flexibility and plasticity. Most thermoplastic films can be tightly wrapped according to the shape of the goods. Whether it is regular or irregular shaped goods, they can achieve adhesive packaging, effectively fix the goods, reduce shaking and displacement during transportation, and provide good protection for the goods.

Secondly, thermoplastic films have excellent transparency, which can clearly display the appearance of goods, making it easy for consumers to identify and purchase products. In food packaging, transparent films allow consumers to visually see the color and condition of the food, increasing product appeal. At the same time, thermoplastic films also have certain barrier properties. Different types of films can block oxygen, water vapor, light, etc., extending the shelf life of goods and maintaining their quality. For example, polyester (PET) film has a good barrier effect on oxygen and water vapor, and is commonly used in the packaging of food and medicine; Polyethylene (PE) film can effectively block water vapor and is suitable for moisture-proof packaging.

In addition, thermoplastic films have excellent processing performance and can be made into products of different specifications and properties through various processes such as blow molding, casting, and stretching, meeting diverse packaging needs. Moreover, thermoplastic films are easy to print and can print exquisite patterns and text on their surfaces, playing a role in promoting and beautifying products. In terms of cost, thermoplastic film raw materials have a wide range of sources and mature production processes. Compared with other packaging materials, it has a higher cost-effectiveness and is therefore widely used in the packaging field.
