Nitrogen-filled fresh-keeping packaging method and production process for high-efficiency and environmentally friendly tea or herbal tea

Abstract

The invention discloses a high-efficiency, environment-friendly tea or herbal tea nitrogen-filled fresh-keeping packaging method and its production process. The packaging tank filling method is adopted, and other soft packaging materials are omitted. The packaging tank is a tinplate can, which includes a tank body , the upper port of the tank body is provided with an inner cover and an outer cover, the inner cover is an aluminum foil inner cover, and the outer cover is a plastic cover, and the tank is directly sealed by the aluminum foil inner cover after filling the tank with nitrogen The upper port of the body is then encapsulated by a plastic cover. The tinplate cans used in the present invention are used for packaging. During the filling process of the tank body, the nitrogen gas technology is injected twice. Nitrogen-filled preservation can better maintain the taste and flavor of the product, and extend the shelf life for at least 3 months. The overall structure can resist compression and deformation, effectively protect products, and reduce express delivery costs. In addition, the tinplate cans used can be recycled and can be used for storage or planting green plants, which can reduce consumables, improve utilization rate, and beautify the environment.

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.
