According to relevant materials, the current demand for pet films is on the rise, most of which are driven by the rapid development of smartphones, and some are demanded by printing companies.

Nowadays, the plastic multi-color printing industry is developing rapidly, accounting for relevant materials. In 2002, the level of high-speed multi-color gravure printers produced by China's own description and production has approached the international level, and the production level of vacuum aluminum plating machines has also continued to improve. Excellent, the annual sales volume is above 100 sets, more than 50 sets of various plastic colorful printers are imported every year, and there are more than 30 sets of high-speed aluminum plating machines. The output value of newly added PET film is at least tons. (Because other films still account for a part) with the further development of China's economy, the further improvement of people's living standards and the development of the Great Northwest will provide excellent opportunities for the development of the PET film industry. After joining the WTO, to keep up with the international level in food packaging, the demand for PET film will be added. The consumption of PET film in the Americas exceeded 380,000 tons in 2000, and it is expected that the annual addition rate will increase by 3%. The average annual addition rate of PET film in the world is about 5%. Usage has decreased, but additions to packaging and other occupations have more than even increased.

The development of China's PET industry is not in harmony with the needs of the market. The demand for anti-scratch film in the market is gradually increasing, while the increase in the PET industry is multiplied, and the types are single. Twenty-five percent of the total, and Yidong Yingfang is the main; magnetic materials account for 28% of the total, mainly Yitei and Toray; other industrial use accounts for 47% of the total Our domestic companies are reluctant to invest in the development of new products, so vicious competition of quotations occurs, quotations are shaken, customers are competing to lower prices, export quotations are too low until anti-dumping, and the company's benefits are rapidly reduced. In order to get out of the predicament as soon as possible, each company must add product categories according to its own advantages and characteristics, advance the product level, jointly develop new products with users, expand the application field of PET film and take the road of product differentiation, in order to make profits and make breakthroughs. Overcome the difficulties of excess film in general.

With the continuous expansion of the smartphone market, it is believed that the demand for pet film will increase steadily, and the pet film market has a broad prospect.
