Tea packaging materials and methods

Ordinary metal cans

The metal cans are made of thin paper, and the cans have a square shape and a cylindrical shape. They are covered with a single cover and a double cover. Its disadvantage is that the seal is not good, and the tea leaves will absorb enough moisture when exposed to moist air for an hour. The softening of the tea will lead to metal odor. At the same time, the tea will be oxidized for a long time and it cannot be stored for a long time.

Composite film bag packaging

More and more commercial tea packaging using composite film bag packaging, its disadvantage is not light, airtight, over time, will make tea mold, smell. Chlorophyll and other components undergo photocatalytic reactions.

Plastic molding container packaging

Polyethylene, polypropylene, polyvinyl chloride and other molded containers for packaging, because of its poor sealing performance, and more as an outer package, its packaging within the use of plastic bags. Because plastics and green tea play a role in chemistry, the taste of tea is lost, and the airtightness is poor. The smell in the cans affects the quality of the tea.

Lined bag boxed

Packaging boxes made of packaging materials are made of paperboard with an inner layer of plastic film or moisture-proof coating. Because the plastic bag and the green tea play a chemical role, the taste of the tea is lost. At the same time, the adhesive and the coating have an odor, which can contaminate the tea and make the tea tasteless. And its tightness is poor.

Tin packaging

Tin cans are the best containers for storing tea. Tin is widely used in food industry at home and abroad. It is the best material for fresh food packaging, also known as "green metal." Because tin cans have the characteristics of strong anti-oxidation ability, good airtightness, low air permeability, good conductivity, no metal odor, etc., they have long been used as a utensil for storing tea and drinking tea. Jars of tea storage for longevity and durability, no mildew, up to 10 years. In particular, fine tea storage tea made from pure tin has the effects of keeping food fresh, preventing oxidation, blocking light, and producing no offensive odor.
