Grey Back PP Film

Food Packaging: Grey Back PP film is often used for packaging food items that need protection from light or to maintain privacy and confidentiality, such as snack packages or frozen food packaging.

Labels: It is ideal for labels that need to be more durable and resistant to fading, commonly seen on products such as bottles and jars that require opacity.

Promotional Materials: Used for printing banners, posters, and other promotional items that require a non-see-through film for added privacy and light-blocking.

Cosmetic Packaging: Grey Back PP film is also used in cosmetic packaging where opacity is important to prevent the products from being exposed to light, which could degrade the contents.

Film Extrusion: The polypropylene resin is first extruded to create a thin film. The film can be made with a grey backing layer, giving it the required opacity and light-blocking effect.

Printing: After extrusion, the film is printed using flexographic or gravure printing methods. The printed design is often applied to the front surface, while the grey back remains unprinted to maintain opacity.

Lamination and Coating: In some cases, additional layers such as a coating or lamination are applied to improve the film’s durability, protect it from wear and tear, and enhance its aesthetic appeal.

Cutting and Shaping: The film is then cut and shaped into the required dimensions for the intended application, whether it be rolls for packaging or sheets for labels.

Opacity and Privacy: The grey back provides excellent opacity, making it ideal for applications that need to prevent light penetration, such as food packaging or confidential labeling.

Durability: Grey Back PP film is highly durable, resistant to tearing, and suitable for various environmental conditions, ensuring long-lasting performance.

Enhanced Aesthetic Appeal: The grey back not only offers functional benefits like privacy and opacity but also improves the overall look of the packaging or product.

Light Blocking: This film is perfect for light-sensitive products, as it blocks out harmful UV rays and prevents degradation from light exposure.

Proper Storage: Grey Back PP film should be stored in a cool, dry place to prevent exposure to excessive heat or humidity, which could affect its integrity.

Printing Considerations: While this film is suitable for various printing methods, the grey back layer should not interfere with the printing process. Proper printing techniques should be used to ensure high-quality results.

Handling: As with all films, it should be handled carefully to avoid any damage or scratches that could affect its opacity and appearance.

Temperature Sensitivity: Extreme temperatures can cause the film to warp or lose its structural properties, so it should not be exposed to high or low temperatures for extended periods.
