Pearl-coated film is a type of plastic packaging material mainly made of polypropylene (PP), featuring a pearl-like luster. Due to its unique pearl-like visual effect and excellent physical properties, it is widely used in packaging, printing, and adhesive products. The BOPP film produced by biaxial stretching has a distinctive pearl-like luster on its surface, combining both aesthetic and practical features.
Outstanding appearance and texture: The most distinctive feature of the pearlescent film is its unique pearl-like luster effect. It is a white high-gloss polypropylene film, presenting a soft and delicate visual appearance. It inherently has an upscale feel, unlike the monotonous nature of ordinary films. This pearl luster is not artificially enhanced but is an inherent optical effect of the material. Under light exposure, it can display a natural and transparent luster, which not only enhances the sophistication of the product packaging but also increases the product's recognizability, enabling the product to stand out quickly among similar competitors.
Excellent covering performance: Compared to ordinary films, the pearlescent film has extremely outstanding covering performance. It can effectively cover the products inside the packaging and the background color of the packaging, completely avoiding the impact on the overall appearance of the packaging due to the transparency of the content color. Whether it is dark-colored cosmetics, alcoholic beverages, or various-shaped foods, the pearlescent film can play a good covering role, especially suitable for product packaging scenarios with high requirements for covering performance, providing a broader space for product packaging design.
Strong processing adaptability: The surface of the pearlescent film has undergone professional coating treatment. This process significantly enhances the comprehensive processing performance of the material. On one hand, the coating significantly improves the printability of the material, enabling it to perfectly adapt to various printing processes, clearly presenting printed patterns, text and colors, and avoiding problems such as smudging, ink bleeding, and color fading, allowing the details of packaging design to be fully presented; on the other hand, the coating also optimizes the die-cutting processing performance, making the pearlescent film more flat and less prone to breaking during cutting, suitable for various packaging processing procedures, effectively improving production efficiency and reducing processing losses.
Pearl film is a white high-gloss film made from polypropylene (PP) as the base material through a special process. Its key features are as follows:
Pearl-like luster, visually superior: The surface presents a soft and delicate pearl-like luster, which can enhance the packaging quality without the need for additional gold stamping or coating. It is particularly suitable for consumer products that value texture and appearance.
Excellent coverage, strong opacity: It has excellent covering performance and can effectively cover the color of the contents and the text, preventing the contents from deteriorating or the information from being confused due to light penetration. It is suitable for dark bottle bodies, products to be stored in a dark place, and non-transparent packaging scenarios.
Surface coating treatment, significantly improved printability and die-cutting performance: Different from traditional pearlescent films, this product's surface has undergone professional coating modification, significantly enhancing the adhesion of ink. High-quality printing can be achieved without complex pre-treatment. At the same time, the coating optimizes the rigidity and toughness of the substrate, improving die-cutting accuracy, facilitating waste removal, reducing dust and burrs, and is suitable for high-speed automatic labeling and special-shaped die-cutting.
Unique appearance: The surface has a fine pearl-like luster, and it can achieve an elegant texture without the need for coating or gold stamping. It also features a glossy side and a matte side (single-sided pearl effect).
Excellent performance: The density is usually lower than that of ordinary BOPP films, making them lighter; it has good light-blocking properties and is non-transparent; it also has certain waterproof, moisture-proof, oil-resistant, and acid-resistant capabilities.
Easy to process: It can be printed, heat-sealed, die-cut, laminated, and some pearlescent films can be stretched in both directions.
Pearl film: Standard type, used for general packaging and printing.
Heat-seal pearl film: One side has a heat-sealing layer, suitable for heat-sealing bag-making.
High haze/low haze pearl film: Adjusting the light transmission and coverage effect according to the haze level.
Synthetic paper (pearl paper): Thicker pearl film, with similar stiffness and writing properties to paper, used for printing, labels, menus, etc.
Appearance: Pearlized film is opaque and has a milky white pearl-like luster; BOPP is transparent or semi-transparent.
Density: The density of the pearlized film is lower, and it has a larger area at the same thickness.
Tensile strength: The pearlized film is more flexible and has a thicker feel; BOPP is softer.
Performance: Waterproof, tear-resistant, and with good printability.
