Tea Packaging Requirements

Moisture resistance

The water content in tea should not exceed 5%, and 3% is the best for long-term storage; otherwise, the ascorbic acid in the tea will be easily decomposed, and the color, aroma and taste of the tea will change, especially at higher temperatures. the rate of deterioration will be accelerated. Therefore, packaging materials with good moisture-proof performance can be selected for moisture-proof packaging, such as composite films based on aluminum foil or aluminum foil evaporated film, which can be highly moisture-proof.

Oxidation resistance

The oxygen content in the package must be controlled below 1%. Too much oxygen will cause some components in the tea to oxidatively deteriorate.

Shading

Since tea contains chlorophyll and other substances, when packaging tea leaves, light must be shielded to prevent the photocatalytic reaction of chlorophyll and other components.

Gas barrier

The aroma of tea leaves is easily lost, and materials with good air-tightness must be used for aroma-preserving packaging.

High temperature

The increase in temperature will speed up the oxidation reaction of tea leaves, and at the same time will cause the surface gloss of tea leaves to fade. Therefore, tea leaves are suitable for storage at low temperatures.
