What is the difference between OPP and Bopp tape?

OPP (Oriented Polypropylene) tape and BOPP (Biaxially Oriented Polypropylene) tape are both types of packaging tapes made from polypropylene, but they differ primarily in how the polypropylene material is processed to achieve different properties.

OPP Tape: This term generally refers to a type of tape where the polypropylene film has been stretched in one direction during its manufacturing process, typically lengthwise. This orientation gives OPP tape certain properties such as strength and clarity, making it suitable for various packaging needs. However, because it’s only oriented in one direction, it might not have the same level of strength or stability across both directions compared to BOPP tape.

BOPP Tape: BOPP tape is made from polypropylene that has been stretched in two directions—both lengthwise and crosswise—during the manufacturing process. This biaxial orientation significantly improves the mechanical properties of the film, including its tensile strength, flexibility, and transparency. As a result, BOPP tapes are more durable, offer better adhesion, and can withstand a wider range of temperatures, making them highly suitable for heavy-duty packaging applications. In summary, while OPP and BOPP tapes share similarities in their base material, BOPP tapes generally provide superior performance due to their enhanced physical properties achieved through the biaxial orientation process. This makes BOPP tape a preferred choice for many industrial and commercial packaging solutions where reliability and durability are crucial.
