We know that Biaxially Oriented Polypropylene (BOPP) products include various types of films, such as glossy film, matte film, pearlized film, aluminized film, laser film and so on. Among them, the BOPP pearlized film labels have gained widespread popularity in various industries due to their unique characteristics and versatile applications. From our must-have tissues, shampoo, and body wash labels to our food and drink mineral water, we all come into contact with it. These labels are known for their visually appealing pearlescent appearance and excellent printing properties. In this article, we will explore the production principle, characteristics, and diverse applications of BOPP pearlized film labels.
Production Principle
The production of BOPP pearlized film labels involves a sophisticated manufacturing process that imparts the distinctive pearlescent effect. The principle behind creating this film lies in the incorporation of special additives during the film extrusion process. These additives typically consist of mica particles, which are thin and reflective minerals derived from natural sources.
During extrusion, the BOPP polymer and mica particles are combined to form a uniform mixture. Subsequently, the film is stretched biaxially, both longitudinally and transversely, to orient the polymer molecules and align the mica particles in a controlled manner. This biaxial orientation enhances the optical properties of the film, resulting in the stunning pearlescent appearance.
A typical pearlized film is a BOPP pearlized film produced by A/B/A three-layer co-extrusion biaxial stretching method, in which B is polypropylene mixed with pearlescent masterbatch, and A is a PP copolymer, which varies with the surface properties of the pearlized film and has good heat sealing performance. The A material layer has the function of protecting the B material layer in the BOPP pearlized film, and endows the pearlized film with a certain heat sealing performance.
Characteristics of BOPP Pearlized Film Labels
- Pearlescent Visual Appeal: One of the most striking features of BOPP pearlized film labels is their captivating pearlescent sheen. The addition of mica particles reflects light in multiple directions, giving the film a lustrous, shimmering effect. This unique visual appeal adds an element of sophistication and elegance to the product packaging.
- Gas barrier, water barrier and light barrier: Pearlized film has pearlescent luster, can reflect more light, and has excellent gas barrier, water barrier and light barrier properties, especially for blocking ultraviolet rays. It provides excellent protection for products that need to be protected from light. Plus, the inherent properties of BOPP make pearlized film labels resistant to moisture, oils, and most common chemicals. This feature is especially beneficial for products that are exposed to challenging environmental conditions or require refrigeration.
- Exceptional Printability: BOPP pearlized film labels offer excellent printability, making them an ideal choice for high-quality graphics and designs. The smooth and even surface of the film ensures that intricate artwork, vibrant colors, and fine details stand out vividly, enhancing the overall shelf appeal of the packaged products.
- Durability and Strength: BOPP pearlized film labels possess exceptional mechanical properties, including high tensile strength and tear resistance. This durability ensures that the labels remain intact during transportation and handling, maintaining the brand’s image and product information throughout the supply chain.
- Versatile and Sustainable: BOPP pearlized film labels are compatible with various printing and labeling technologies, including flexographic, gravure, and digital printing. Moreover, BOPP is a recyclable and environmentally friendly material, making these labels a sustainable packaging option for brands committed to reducing their carbon footprint.
- Cost saving: Different from ordinary BOPP film, the density of pearl film is mostly controlled below 0.7. Its lower density requires less material, which saves costs.
Applications of BOPP Pearlized Film Labels
- Consumer Packaged Goods (CPG): BOPP pearlized film labels find extensive use in the CPG industry for labeling a wide range of products such as cosmetics, personal care items, beverages, and confectioneries. The labels’ eye-catching appearance helps products stand out on store shelves, capturing consumers’ attention and influencing their purchasing decisions.
- Premium and Luxury Products: Brands that cater to the premium and luxury market segments often choose BOPP pearlized film labels to add an element of opulence to their packaging. The pearlescent effect exudes elegance and sophistication, enhancing the perceived value of the product.
- Promotional and Seasonal Items: Companies often use BOPP pearlized film labels for seasonal or promotional product packaging. The shimmering appearance of these labels complements holiday-themed designs, making them perfect for limited edition releases or festive packaging.
- Home and Personal Care Labels: BOPP pearlized film labels are commonly used in the home and personal care industry for labeling products like detergents, cleaning agents, and toiletries. The durability and moisture resistance of the labels make them suitable for products typically used in household and bathroom environments.
Conclusion
BOPP pearlized film labels offer a unique combination of visual appeal, excellent printability, durability, and versatility, making them an ideal choice for a wide range of applications. Their production principle, involving the incorporation of mica particles during extrusion, results in the distinctive pearlescent effect that sets them apart from conventional labeling options. As consumer preferences continue to lean towards premium and aesthetically pleasing packaging, BOPP pearlized film labels are likely to remain a popular choice for brands aiming to enhance their product’s shelf presence and overall brand image.
