BOPP granules refer to granules or pellets made from a type of plastic known as biaxially oriented polypropylene (BOPP). Polypropylene is a thermoplastic polymer that is widely used in a variety of applications, including packaging materials, textiles, and consumer products.
BOPP is a specific type of polypropylene that has been stretched in two different directions during the manufacturing process, resulting in a material that is highly durable, transparent, and resistant to moisture and chemicals. BOPP granules are commonly used in the production of a wide range of plastic products, including bags, pouches, labels, and other types of flexible packaging.
BOPP granules are typically produced by melting down the raw BOPP material and then extruding it through a die to create pellets or granules of uniform size and shape. These granules can then be further processed into various finished products through processes such as injection molding, blow molding, or film extrusion.
