Efficient and environment-friendly nitrogen-filled fresh-keeping packaging mode for tea or herbal tea and production process thereof

Abstract

The invention discloses an efficient and environment-friendly nitrogen-filled fresh-keeping packaging mode for tea or herbal tea and a production process thereof. A packaging can filling mode is adopted, and other flexible packaging materials are omitted; a packaging can is a tinplate can and comprises a can body; an inner cover and an outer cover are arranged at an upper end opening of the can body; the inner cover is an aluminum foil inner cover, and the outer cover is a plastic sealing cover; after the can body is filled with materials and nitrogen, the upper end opening of the can body isdirectly sealed through the aluminum foil inner cover, and then the can body is packaged through the plastic sealing cover; the tinplate can is adopted for packaging, the nitrogen filling technology is conducted twice in the material filling process of the can body, the taste, flavor and the like of products can be better kept through nitrogen filling fresh keeping, and the shelf life is prolongedby at least three months; the can body structure can resist pressure and deformation, the products are effectively protected, and the express cost is reduced; and in addition, the adopted tinplate can be recycled and can be used for storage or planting green plants, consumables can be reduced, the utilization rate can be increased, and the environment can be beautified.

Description

Technical field: [0001] The invention relates to a packaging method for tea or herbal tea, and mainly relates to a nitrogen-filled and fresh-keeping packaging method for high-efficiency and environment-friendly tea or herbal tea and a production process thereof.
