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 that are highly vulnerable to oxygen, moisture, and ultraviolet exposure. In cross-border logistics, long-term overseas warehousing, and Western retail shelf environments, insufficient packaging protection easily triggers aroma volatilization, flavor degradation, and color fading. Unlike pre-sealed tea bags, bulk tea requires continuous and stable barrier protection throughout its sales cycle. In 2026 global tea exports, shelf stability has become a critical evaluation metric, equally important with food contact compliance and EU PPWR recyclability standards.
