In 2022, the Tea Research Association found that matcha can lose up to 68 per cent of its chlorophyll content in as little as 12 weeks if stored in a non-airtight container. Improper storage not only dulls the bright green colour of matcha and makes it lifeless, but also reduces its flavour and the rich antioxidant content, making it a much lesser matcha. For tea brands, packaging is more than visual appeal—it's the science of preservation. In this article, we explore how to choose the right matcha tin in terms of size, style, and sustainability to protect product quality and reflect brand identity.   Why Airtight Matcha Tins Preserve Freshness Better Matcha is so fine, the particles are like little powders. It's also super high in antioxidants, especially EGCG, which is great. But because it's so “delicate”, it's particularly susceptible to oxidation, and if you expose it to UV rays or leave it in a humid environment, the quality will immediately deteriorate. EGCG (Epigallocatechin gallate), the key antioxidant in matcha, decreases when exposed to air. Chlorophyll, responsible for matcha’s vibrant color, breaks down under light exposure. Moisture absorption leads to clumping and bitterness. Airtight matcha tin containers offer triple-layer protection: they block light, resist moisture, and reduce oxygen exposure—making them ideal for both short- and long-term storage.   Matcha Tin Sizes Explained: From 30g to Bulk Packaging Tin size selection is not just about capacity—it impacts logistics, user experience, and cost efficiency.
