BOPP (Biaxially Oriented PolyPropylene) films are widely used in various applications, including packaging, labeling, and lamination. Here are some key points about BOPP films and their applications:
- Food Packaging: BOPP films are preferred substrates for food packaging globally. They offer an effective moisture barrier, protecting food products from moisture absorption or loss. BOPP films are often used as co-extruded heat-sealable reverse printable films for applications like snack packaging, biscuit packaging, and lidding films for trays.
- Labeling Applications: BOPP films are widely used in labeling due to their yield benefits and recyclability. They provide good printability and can be surface-treated to enhance ink adhesion. BOPP films are used for in-mold labeling (IML), pressure-sensitive labels, wrap-around labels, and shrink sleeves. The low density of BOPP films contributes to the desired “orange peel effect” in IML applications.
- Lamination: BOPP films are used in lamination processes to enhance the appearance, durability, and barrier properties of packaging materials. They are often used as the outer layer in laminated structures for pouches, bags, and flexible packaging.
- Recyclability: BOPP films are recyclable along with other polypropylene (PP) materials, making them an environmentally friendly packaging solution. The recyclability of BOPP films contributes to sustainability efforts and the circular economy.
- Versatility: BOPP films offer versatility in terms of thickness, surface treatment, and additional functionalities like anti-fog, anti-static, and UV resistance. This allows manufacturers to tailor the films to specific packaging requirements.
