company news about Barrier Performance and Shelf Stability: Core Advantages of Paper Cans in Loose Leaf Tea Packaging

Loose leaf tea and herbal tea feature open fiber structures with rich volatile aromas and active botanical ingredients, making them extremely sensitive to oxygen, moisture and ultraviolet radiation. In complex cross-border logistics, long-term overseas warehousing and Western retail shelf environments, insufficient packaging protection easily causes aroma volatilization, flavor degradation and color fading. Unlike pre-sealed tea bags, bulk tea requires continuous and stable barrier protection throughout the entire sales cycle.
