The heat transfer film can be made into films of various colours. Pvc heat transfer film is used in the sales and transportation of various products. Its main function is to stabilize, cover and protect the product against scratching and scattering. The heat transfer film must have high puncture resistance, good shrinkage and certain shrinkage stress. In the process of shrinkage, the film cannot generate holes, and the temperature during shrinkage cannot be too high, otherwise, the surface temperature of the film will be too high to cause the film to break holes.

The heat transfer film is mainly used for packaging products, and its characteristics are as follows:

1. First of all, the heat transfer film has good sealing performance and high strength, which can be used to package products with regular and irregular shapes.

2. Secondly, the heat transfer film has high transparency and good gloss. Therefore, the product packaged with the heat transfer film can clearly show the appearance of the product so that people can understand the product more clearly.

3. The heat transfer film has a large shrinkage rate and good flexibility, which greatly meets the requirements of most customers and is also favoured by many customers.

Regenerated packaging materials are mainly plastic packaging. After physical treatment, they can be made into regenerated packaging containers. After chemical treatment, they can be made into regenerated packaging products. Reused packaging materials are mainly used for packaging beer, beverages and other glass bottles, which can be reused many times. However, these two methods have both advantages and disadvantages. They only reduce the pollution to the environment. At the end of the day, they have to face the problem of environmental pollution. With the concept of low carbon and environmental protection becoming the main theme of the society, many fields are practising it, as is the packaging material field.

The heat transfer film can be used for transporting various products, thus protecting the products, because the heat transfer film has better shrinkage performance and is loved by people. The following are the inspection standards for heat transfer films:

1. When inspecting the heat transfer film, first look at the surface of the heat transfer film to see whether the transparency of the heat transfer film is good, whether the color is bright, whether there is any damage, whether it is perforated, etc.

2. Don't forget to check the flatness of the heat transfer film to see if there are wrinkles and signs of shrinkage.

3. Another thing is to look at the outer package of the heat transfer film and see if there is any information such as product name, manufacturer, date, quantity, etc. on the surface. The surface should be smooth, clean and free of dust.
