How is the excellent barrier performance of metallized BOPP film achieved?

Metalized BOPP film, as a shining pearl in the field of modern packaging, has won widespread favor in the market with its unique metallic luster and excellent performance. Among these properties, its excellent barrier properties are particularly eye-catching. So, how is this excellent barrier performance achieved?

We need to understand the basic structure of metallized BOPP film. It is based on the traditional BOPP film and attaches the metal layer to the surface of the film through a specific process. This metal layer not only gives the film a metallic luster, but more importantly, it greatly enhances the barrier capability of the film.

The existence of the metal layer is like a strong barrier, effectively blocking the intrusion of outside air, moisture and other impurities. Since the metal itself has the characteristics of high density and impermeability, when this layer of metal is evenly attached to the surface of the BOPP film, it can form a strong layer of protection for the film, insulating the items inside the film from the outside environment. Come.

In addition, the barrier properties of metallized BOPP films are closely related to their production processes. During the preparation process, by precisely controlling the thickness, uniformity and attachment method of the metal layer, the barrier properties of the film can be ensured to be optimal. At the same time, the treatment of the BOPP film itself is also crucial. Through the biaxial stretching process, the molecules of the film can be arranged more closely, thereby improving its barrier properties.

In addition to the structure and manufacturing process, the barrier properties of metallized BOPP films are also affected by some external factors. For example, environmental factors such as temperature and humidity may affect the barrier properties of the film. Therefore, during use and storage, attention needs to be paid to maintaining appropriate environmental conditions to ensure that the barrier properties of the film can be stably exerted.

The excellent barrier properties of metallized BOPP film are achieved through its unique structure, production process and suitable use environment. This film not only has a metallic luster and texture, but also has strong barrier capabilities, providing more comprehensive and effective protection for goods. In the future packaging field, metallized BOPP film will continue to exert its unique advantages and bring more convenience and beauty to our lives.
