Description

A kind of lining paper coated with oolong tea extract

technical field

The invention relates to an auxiliary material for cigarettes, in particular to an inner lining paper coated with oolong tea extract.

Background technique

The inner lining paper is the paper lining the inner layer of the small cigarette box and wrapping the cigarette directly. The inner lining paper provides a microenvironment for cigarettes, which can keep the moisture and aroma of cigarettes and prevent moisture. Lining paper mainly includes calendered aluminum foil paper, aluminized paper, general lining paper, etc. The inner lining paper should have good moisture-proof and moisture-proof properties to prevent cigarette mildew and the loss of cigarette aroma, and the texture should be soft and easy to fold without breaking. With the development of the cigarette industry, the requirements for cigarette packaging materials are gradually increasing in terms of flavor enhancement, moisturization, environmental protection, and naturalness. The role of the lining paper is no longer limited to the traditional anti-mildew and quality assurance, how to provide consumers with an elegant cigarette pack opening fragrance is also a direction of its development.

There are 4 varieties of oolong tea, namely Tieguanyin, Huangdan (also known as Huangjingui), Benshan and Maoxie.

Tieguanyin: Pure Tieguanyin is also known as Red Heart Avalokitesvara or Red Avalokitesvara. Tieguanyin is the best oolong tea. Its quality characteristics are: the tea sticks are curly, fat and round, heavy and even, with a sandy green color, and the overall shape is like a dragonfly's head, a spiral body, and a frog's leg. After brewing, the soup color is golden and rich like amber, with a natural and rich orchid fragrance, mellow and sweet taste, and a long aftertaste, commonly known as "phonology".

Huangdan (also known as Huangjingui): Huangjingui is an oolong tea made from the tender shoots of the Huangdan tea tree. It is named Huangjingui because of its golden color and unique fragrance like osmanthus. Among the existing oolong tea varieties, it is the earliest to germinate. The oolong tea produced has a particularly high aroma, so it is called "Qingming tea" and "Toutian fragrance" in the production area, and has the reputation of "two wonders in the morning". The annual growth period is 8 months.

Benshan: The tea sticks are strong and heavy, with bright stems and thinner; the tail is slightly pointed like "Bamboo Festival", and the color is bright and moist like banana skin; the tea soup is orange-yellow; the fragrance is like Tieguanyin but lighter. It is a "close relative" with Tieguanyin, but its growth and adaptability are stronger than Tieguanyin. The quality of oolong tea is excellent, with high aroma and mellow taste, and its good quality is similar to Tieguanyin. Made into red and green tea, the quality is medium.

Hairy crab: The tea sticks are tightly knotted, the head is large and the tail is pointed, the buds and leaves are tender, with many white hairs, the color is brownish yellow green, still fresh and moist. The tea soup is greenish yellow or golden yellow. The taste is pure and slightly thick, with a high fragrance and a slight jasmine fragrance. It is suitable for making oolong tea, which is a high-grade "color" raw material; for making red and green tea, the color is exposed, the appearance is beautiful, and the quality is good.

Chinese patent CN201010584511.4 discloses a cigarette bale lining paper with natural tobacco extract as the main coating raw material. Chinese patent CN201010613331.4 discloses an additive mainly made of natural tobacco extracts, tobacco aroma substances and plant extracts to cover up and improve the odor of dark-colored tipping paper. But there is no report of oolong tea extract coating on the inner lining paper yet.
