– Assess your product requirements: Determine whether your packaging needs align more with the attributes of PET or PP.
– Consider cost implications: While PET is generally less expensive, the longevity and performance of PP in specific applications may justify the higher cost.
– Engage with suppliers who understand regional market nuances to ensure compliance and quality.

As you move forward, prioritize strategic sourcing decisions that not only meet your immediate needs but also position your brand for sustainable growth in a competitive landscape. Embrace innovation and adapt to consumer preferences to thrive in the dynamic world of food packaging.
