Masterbatch and BOPET

Masterbatch is an additive specially used for coloring plastic products and plays an extremely important role in the preparation of BOPET cast film.BOPET is a kind of polyester film, which is widely used in food packaging, pharmaceutical packaging, electronic product packaging and other fields.In the production process of BOPET cast film, adding a masterbatch can realize the customization of the color of the film, effectively improving the appearance quality and market competitiveness of the product.

Advantages of the role of masterbatch in BOPET cast film (2)

First of all, the use of masterbatch can effectively improve the color vividness and saturation of BOPET cast film.Traditional coloring methods often only produce a single color, while masterbatch allows the film to achieve a combination of multiple colors to meet the needs of different markets.In addition, the masterbatch can also fine-tune the parameters of the film's hue, brightness, and saturation to make the color of the film more natural and delicate.

Secondly, the use of masterbatch can improve the weather resistance and UV resistance of BOPET cast film.In the production process, adding ultraviolet absorbers and antioxidants in moderation can effectively extend the service life and color retention time of the film, thereby reducing production costs and providing consumers with better products.

The use of masterbatch can also improve the production efficiency and product quality of BOPET cast film.Compared with traditional coloring methods, it requires multiple coating and drying, which is not only time-consuming and energy-consuming, but also prone to quality problems such as air bubbles and color differences.The color masterbatch is directly added to the film production process without additional coating and drying, which greatly shortens the production cycle and improves production efficiency.At the same time, the addition of the masterbatch can also make the color of the film more uniform and stable, and avoid quality problems such as color difference.

In summary, the masterbatch plays a vital role in the preparation of BOPET cast film.It can not only realize the customization of the color of the film, improve the appearance quality and market competitiveness of the product, but also enhance the weather resistance and UV resistance of the film, extend the service life and color retention time.At the same time, the use of masterbatch can also improve production efficiency and product quality. Therefore, masterbatch is a very excellent additive.
