Detailed Project Report (DPR) on bopp film

BOPP film is mainly used for packaging, labelling, and lamination applications. In food packaging, it is commonly used as a co-extruded heat-sealable and reverse-printable film. Its moisture barrier, clarity, seal integrity, machinability, and graphic reproduction make it suitable for protecting and presenting packaged products. Different BOPP variants, including clear, white opaque, and metallized films, can provide different combinations of appearance, barrier performance, and functional properties for food and non-food packaging structures.

BOPP film is preferred for food packaging because it combines moisture resistance, sealability, clarity, strength, and good printability. Its barrier properties can help protect packaged products and support longer shelf life, while consistent seal integrity and good machinability support efficient packaging operations. Metallized BOPP can provide improved oxygen barrier performance. Its low density also enables good material yield, while clear, white opaque, and metallized variants provide different visual and functional characteristics for packaging.

The main advantages of BOPP film include barrier performance, product protection, attractive graphics, low density, and good processing characteristics. BOPP provides moisture resistance and, in metallized form, improved oxygen barrier properties. It also offers good heat-seal strength, a broad sealing window, high transparency, gloss, opacity in white grades, and metallic appearance in metallized grades. Its relatively low density can improve material yield and reduce weight for a given film length, supporting efficient handling and conversion.

BOPP film generally requires corona treatment to improve its surface characteristics for printing and coating. Untreated BOPP has low surface energy, which can make adhesion of inks, coatings, and other materials difficult. Corona treatment modifies the film surface and improves its printing adaptability. This enables high-quality colour printing and supports the use of BOPP as a surface layer in composite packaging films. Appropriate treatment levels and process controls are important to achieve consistent downstream performance.

BOPP film is manufactured by melting polypropylene, forming it into a sheet or thick film, and stretching it in longitudinal and transverse directions. The polypropylene melt is formed through a narrow machine head and subsequently processed in a dedicated stretching machine under controlled temperature and speed conditions. Orientation may be performed simultaneously or step by step. The film can then undergo cooling, heat treatment, corona treatment, coating, or other specialized processing depending on its intended application and performance requirements.

The feasibility report proposes a BOPP Film production facility as a Green Field Project with a stated plant capacity of 25 Ton./Day. The report also describes the project as intended for 7500 MT/Year BOPP Film production facilities. These capacity figures are presented as provided in the project report and have not been recalculated or modified. The proposed facility is intended to support the manufacture of BOPP films for applications including packaging, labelling, and lamination.
