How is the tea square box packaged?
As a special kind of commodity, the tea square box is different from the packaging of other general commodities due to its own and objective conditions. At present, the commonly used tea packaging methods mainly include the following.
1, metal can packaging
The metal can packaging is excellent in anti-breakage, moisture-proof and sealing performance, and is an ideal packaging for tea. Metal cans are generally made of tin-plated steel sheets, which are square and cylindrical, and are covered with a single layer cover and a double layer cover. There are two types of general tanks and sealed tanks. In the packaging technology processing, the general tank can be enclosed in a deoxidizer packaging method to remove oxygen in the package. Sealed tanks are mostly inflated and vacuum packed. The metal can is superior to the composite film in the protection of the tea, and the appearance is beautiful and noble. The disadvantage is that the packaging cost is high, the weight ratio of the package to the commodity is high, and the transportation cost is increased. The exquisitely designed metal cans are suitable for the packaging of high-grade tea.
2, carton packaging
The paper box is formed by printing on white paper, gray board paper, etc. The carton package is easy to break and the shading performance is excellent. In order to solve the volatilization of the tea leaves in the carton packaging and to avoid the external odor, the tea leaves are generally packed in polyethylene plastic bags and then loaded into the carton. The disadvantage of carton packaging is that it is susceptible to moisture. In recent years, paper-plastic composite packaging boxes have emerged to overcome the problem of moisture-absorbing carton. This kind of paperboard made of plastic film layer or moisture-proof coating is made of packaging material. The packaging box not only has the function of packaging the composite film bag, but also has the protection and rigidity of the carton packaging. If a plastic bag is used as a small bag inside, the protective effect is better.
3, plastic molded container packaging
Polyethylene, polypropylene, polyvinyl chloride and other plastic molding containers have the characteristics of generous, beautiful, and good packaging display effect, but their sealing performance is poor. They are mostly used as outer packaging in tea packaging, and multi-purpose composite plastic bags are used in the packaging. Package.
4, composite film bag packaging
Plastic composite film has many advantages such as light weight, not easy to break, good heat sealability and reasonable price, and is widely used in packaging. There are many kinds of composite films for tea packaging, such as moisture-proof cellophane/polyethylene/paper/aluminum foil/polyethylene, biaxially oriented polypropylene/aluminum foil/polyethylene, polyethylene/polyvinylidene chloride/polyethylene, etc. The composite film has excellent gas barrier properties, moisture resistance, aroma retention, odor prevention and the like. Since most plastic films have a light transmittance of 80% to 90%, in order to reduce the transmittance, ultraviolet light suppression can be added to the packaging material or the light transmittance can be reduced by printing or coloring. In addition, a composite material based on an aluminum foil or a vacuum aluminized film may be used for the light-shielding packaging. The composite film bag is packaged in a variety of forms, including a three-sided sealing shape, a self-standing bag shape, a folding shape, and the like. Because the composite film bag has good printability, it is used for sales packaging design, which has a unique effect on attracting customers and promoting tea sales.
Also known as teabag, this is a kind of bag packaging made of thin filter paper for the village, and it is put into the tea set together with the paper bag. The purpose of packaging in a filter paper bag is mainly to increase the leaching rate, and also to make full use of the tea plant tea. Because the tea bag has the advantages of fast brewing, clean and hygienic, standard dosage, convenient mixing, convenient slag discharge, easy to carry, etc., it can adapt to the fast-paced life needs of modern people and is very popular in the international market. Early bagged teas generally have bag lines to meet the convenience of multiple soaking. Due to environmental protection requirements, bagged tea without bag lines is now becoming popular.
