Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to a tangerine peel storage packaging bag. Background Art

[0002] Tangerine peel, a tonic food that can be used as both medicine and food, is widely used in Chinese medicine. It has the effects of regulating qi and digestion, resolving phlegm and relieving cough, and nourishing the spleen and stomach. It is an indispensable health food in daily life. In traditional Chinese medicine, it is often said that "a hundred years of dried tangerine peel is as good as a thousand years of ginseng." The old people also often say that "one ounce of dried tangerine peel is worth one ounce of gold", which shows that dried tangerine peel has very high medicinal and health value. There is a saying that "the older the dried tangerine peel is, the better it is", that is, the longer the aging time, the higher its medicinal value. However, due to the long aging cycle and unstable quality of dried tangerine peel, its medicinal and economic value still has a lot of room for improvement. Dried tangerine peel often becomes moldy and grows insects during storage. At present, the packaging forms used for storing dried tangerine peel are mainly glass jars, plastic jars, plastic bags, clay jars, metal cans, etc. Although they can play a moisture-proof role to a certain extent, their sealing and moisture-proof properties are not as good as plastic packaging bags during long-term storage, and it is still difficult to effectively prevent dried tangerine peel from getting damp and mildewing, especially in the southern region with high humidity. Dried tangerine peel is more likely to absorb moisture and deteriorate, which is not conducive to its aging. Although plastic packaging bags can effectively protect dried tangerine peel from external moisture, pests, bacteria, etc., plastics are not easy to degrade, and they are easy to damage the soil and marine ecosystems after being discarded.

[0003] It is particularly important to seek a new type of packaging material that can not only meet the moisture-proof and insect-proof requirements for long-term storage of tangerine peel, but also respond to environmental protection policies and reduce dependence on plastic. Packaging products made of bamboo can replace plastic packaging in many fields, realizing "replacing plastic with bamboo". At present, packaging materials are developing in the direction of greening, low carbonization, lightweighting and functionalization. Bamboo fiber, as a 100% green packaging material, has broad prospects in the packaging field. Therefore, it is of great practical significance to prepare a tangerine peel storage packaging bag based on bamboo fiber. Summary of the invention
