The metallized BOPP film is based on biaxially oriented polypropylene (BOPP) and adopts a single-layer heat-sealed design. The corona-treated surface is aluminized, while the other side is kept smooth. Corona treatment is a key step in improving the surface performance of the film. By forming a microscopic rough structure on the film surface and introducing polar groups, the surface energy is significantly increased, creating good conditions for the subsequent adhesion of the aluminized layer. The aluminizing process uses vacuum evaporation technology to heat and evaporate aluminum metal in a high vacuum environment. Aluminum vapor is deposited on the surface of the film to form a uniform and dense metal layer. This aluminized layer not only gives the film a metallic luster, but also greatly improves the barrier performance. The smooth surface maintains the original smooth texture of the BOPP film. ​


Multiple performance advantages create excellent quality​
The metallized BOPP film has a series of outstanding performance advantages. Its glossy appearance is very visually attractive. The aluminized layer makes the film surface present a mirror-like metallic luster, which can effectively improve the grade and recognition of the packaged product, stand out in the shelf display, and attract consumers' attention. The easy-tear performance is a highlight of the film. Its special material structure and process treatment enable the film to have good tearing characteristics while maintaining a certain strength. Consumers can easily open the package without the help of tools, which significantly improves the convenience of use while ensuring the integrity of the package. ​In terms of functionality, metallized BOPP film also performs well. With the dense structure of the aluminum-plated layer, it has a good barrier function and can effectively block external factors such as oxygen, water vapor, and light that have adverse effects on the contents, extend the shelf life of food, and maintain the freshness of flowers. The film is a printing, heat-sealing, and laminating grade material with good adhesion to inks, glues, etc. Whether it is printed with exquisite patterns using gravure printing, flexographic printing, or bag making through heat-sealing technology, or laminated with other materials, it can present a uniform, firm and high-brightness effect to meet the diverse packaging processing needs. ​


Wide application scenarios highlight practical value​
Based on its excellent performance, metallized BOPP film is widely used in the fields of food packaging and flower packaging. In terms of food packaging, whether it is snacks, baked goods, dry goods, condiments, etc., metallized BOPP film can provide reliable protection for products. Its good barrier properties can prevent food from oxidation and deterioration, dampness and mold, and maintain the color, aroma, taste and nutritional content of food; the beautiful glossy appearance helps to enhance the market competitiveness of food and attract consumers to buy. ​In the field of flower packaging, metallized BOPP film also plays an important role. Flowers have strict requirements on the storage environment and need to avoid water loss, bacterial invasion and mechanical damage. The barrier function of metallized BOPP film can effectively reduce water evaporation and maintain the freshness of flowers; at the same time, its certain mechanical strength can provide physical protection for flowers and prevent flowers from being damaged during transportation and sales. The exquisite appearance can also add beauty to flowers and enhance the added value of products. ​


Unique substrate and cost advantage enhance market competitiveness
Metallized BOPP film uses a unique BOPP substrate, which has obvious advantages in cost compared with other packaging materials. BOPP materials are widely available, the production process is mature, and large-scale production makes its raw material cost relatively low. The metallized BOPP film processed on this basis can effectively control production costs while ensuring high performance, providing packaging companies with a more cost-effective option. For brand owners, the use of metallized BOPP film can not only meet the requirements for packaging quality and function, but also reduce packaging costs, improve product market competitiveness, and achieve a win-win situation in economic benefits and packaging effects.
