For premium tea, the true value lies in the delicate volatile oils that create its unique aroma. However, once exposed to oxygen, humidity, or external odors, those qualities degrade rapidly. **3D Overwrapping** (also known as tuck-and-fold wrapping) has become the gold standard for luxury tea brands to ensure that the "first sip" experience is preserved from the factory to the consumer's cup.

1. What is 3D Overwrapping?

Unlike standard shrink wrapping, 3D overwrapping uses a precise mechanical "fold and tuck" method—similar to a gift wrap. It utilizes BOPP or Cellophane film to create a sleek, six-sided seal without subjecting the delicate tea leaves to the high heat of a shrink tunnel, making it perfect for heat-sensitive products like tea and perfumes.
