Alu Foil Food Grade Jumbo Roll Aluminium Foil 9 Micron
In our daily life, some people like to drink tea, so they also like to collect all kinds of good tea. For those who love tea, good tea can be said to be the most precious thing, and there are many points to pay attention to in the storage of tea.
For example, tea leaves cannot see moisture. Once it is eroded by moisture, it will affect the taste of the tea and may even make the tea mildew. This is the last thing all tea collectors want to see.
In addition, the excessive oxygen content in its packaging will cause the oxidative deterioration of certain components in the tea. For example, ascorbic acid is easily oxidized to deoxyascorbic acid, and further combines with amino acids to cause a pigment reaction, which makes the tea taste worse. Therefore, the oxygen content in tea packaging must be effectively controlled below 1%.
In packaging technology, inflatable packaging or vacuum packaging can be used to reduce the presence of oxygen. Vacuum packaging technology is a packaging method in which tea is packed into a flexible film packaging bag with good airtightness, and the air in the bag is removed during packaging, resulting in a certain degree of vacuum, and then sealed and sealed.
The purpose of this method is to protect the color, aroma, and taste of tea leaves to remain stable and maintain their original quality.
The aroma of tea is easily lost and is easily affected by external odors. In particular, the residual solvents of the composite film and the odors decomposed by electric ironing and heat sealing treatments will affect the flavor of the tea and affect the aroma of the tea.
Therefore, when packaging tea, it is necessary to avoid escaping aroma from the packaging and absorbing peculiar smell from the outside. Tea packaging materials must have certain gas barrier properties, and aluminum foil can perfectly meet this requirement.
The characteristics of the aluminum foil itself fully meet all the requirements of tea packaging. Its existence ensures that the tea can be well preserved and the original flavor is preserved.
Aluminum Foil 8011 Jumbo Roll Food Grade 8011 Alloy There is only one choice of packaging material that can meet all the above conditions and the most used packaging material under the same conditions, that is, aluminum foil, which is the packaging material that best meets all the above conditions.
