Birth of a Bag: From Resins to Reels

The story begins with two key players:

Biaxially Oriented Polypropylene (BOPP): This versatile plastic film is the foundation of BOPP bags. It's derived from polypropylene (PP) resins, a petroleum-based plastic known for its strength and clarity.

Polyethylene (PE): While not always used, some BOPP bag variations might incorporate PE for specific functionalities.

Here's a breakdown of the BOPP bag creation process:

Resin Preparation:  The PP resins are carefully processed to remove impurities and ensure consistent quality.

Film Extrusion:  The molten PP resin is forced through a die shaped like a flat sheet, creating a continuous film of BOPP.

Biaxial Orientation:  This is the step that gives BOPP its unique properties. The film is stretched in both machine and transverse directions under controlled heat and tension. This process enhances its strength, clarity, and dimensional stability.

Surface Treatment (Optional):  For improved printability, the Bopp Rice bags film might undergo a surface treatment like corona treatment, which modifies the surface energy to allow inks and adhesives to adhere better.

Printing (Optional):  BOPP film can be printed with vibrant colors and graphics using various printing techniques like flexography or rotogravure. This customization allows for branding, product information, or eye-catching designs.

Slitting & Bag Making:   The wide BOPP film is then precisely slit into narrower rolls based on the desired bag size. Specialized machinery then converts the film into finished bags. This may involve cutting, folding, sealing the edges, and adding features like handles or resealable closures.

Quality Control:  Throughout the process, stringent quality checks ensure the BOPP bags meet specifications for strength, clarity, seal integrity, and printability.
