Tea packaging method

Abstract

The invention discloses a tea packaging method. An existing tea packaging method easily causes tea aroma losing, and secondary sealing is difficulty. According to the tea packaging method, finished product tea is placed in a plurality of small plastic packaging bags, and every small plastic packaging bag is packaged through a zipper; every small plastic packaging bag is inflated with nitrogen of 1-2 atmospheric pressures; the small plastic packaging bags are sealed and placed in a large packaging bag; the large packaging bag is accommodated in a paper can, and quicklime is accommodated in a net bag in the paper can; and the paper can is packaged in a sealed mode through a plastic bag. The tea packaging method is low in cost, and tea is simple and convenient to seal after unsealed.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to a tea packaging method. Background technique [0002] Existing tea leaves are directly packaged in cans made of paper, iron, etc. after being roasted in the tea production area. After unpacking, this type of tea is easy to be damp and the aroma is easy to lose, and it is also packaged in plastic bags first. After that, put it into cans. Although this kind of packaging has the sealing effect of plastic bags, it is easy to be heated during the product transportation and sales process, which will cause the tea to lose its fragrance and even deteriorate; and the plastic bags are generally made by melting the plastic. After opening the package, it is difficult to seal. [0003] In my country's patent application, it is useful to inject nitrogen gas to increase the fresh-keeping period of tea leaves, such as patent No. 91103805.1, which has high requirements for packaging and high...

[0002] Existing tea leaves are directly packaged in cans made of paper, iron, etc. after the tea is roasted in the place of origin. After unpacking, this type of tea is easy to be damp and the aroma is easy to lose, and it is also packaged in plastic bags first. After that, put it into the can. Although this kind of packaging has the sealing effect of plastic bags, it is easy to be heated during the product transportation and sales process, which will cause the tea to lose its fragrance and even deteriorate; and the plastic bags are generally made by melting the plastic.
