Due to the rapid development of BOPP film in the past few years, the production capacity has increased sharply. In 2006, there were only a few production lines. , Film width reaches 8.2m, line speed 400m/min advanced technology. The other production capacities were formed by the introduction of large quantities in previous years. In 2006, the production capacity was 400,000 tons, and the output was only 285,000 tons. In the absence of new production capacity, the market is still oversupplied. Single variety and narrow market scope are the main reasons. Therefore, only by developing new products and giving new functions can new application fields be expanded. There is great potential in this industry, such as high-strength film, high-transparency film, anti-static film, surface conductive film, flame-retardant film, heat-sealing film, etc. film, heat shrinkable film, etc. According to their own conditions, technical strength and market demand, enterprises can selectively develop special films, implement product differentiation strategies, and avoid product similarity. In this regard, the packaging materials of Aantec new material are in an invincible position despite their small scale. Although Aantec facility is a 10,000-ton enterprise, it has not forgotten to develop special films. They use local high-tech industry funds to establish technology centers, develop special polyester film experimental lines, improve their product research and development capabilities, and improve competitiveness.
