Pronunciation: [bˈɒp] (IPA) 
BOPP is a commonly used abbreviation for biaxially oriented polypropylene, a type of plastic used for packaging, labels, and other industrial applications. The spelling of BOPP is pronounced as /bɒp/ in IPA phonetics, representing the short "o" sound followed by the unvoiced "p" sound. The spelling of BOPP is straightforward and easy to remember, as it is simply an acronym for the full name of the plastic polymer from which it is made.
BOPP stands for Biaxially Oriented Polypropylene. It is a widely used type of plastic film that has been stretched in both directions, resulting in enhanced tensile strength, clarity, and resistance to moisture and heat. BOPP film is commonly found in flexible packaging applications due to its versatile properties.
BOPP films are typically manufactured by extruding polypropylene, a thermoplastic polymer, into a thin film and then biaxially stretching it. This biaxial orientation process aligns the molecules within the film, enhancing its strength and providing excellent optical properties. The film is then heat set to stabilize it and maintain the stretched state.
The key characteristics of BOPP film include outstanding transparency, glossy appearance, excellent printability, and resistance to water, grease, and chemicals. It is also known for its efficient barrier properties, safeguarding the packaged products against moisture and other potential contaminants. BOPP films are widely used in various industries such as food, pharmaceuticals, textiles, and stationery.
In packaging, BOPP films are commonly used for flexible packaging solutions, including snack food bags, cereal box liners, confectionery wrappers, and labels. Their high clarity makes them perfect for showcasing the contents of the package, while their excellent sealability ensures product freshness and tamper resistance.
Overall, BOPP is a versatile plastic film that offers a wide range of applications in the packaging industry, providing durability, clarity, and protection to various products.
