The tea packaging mainly includes tin tea cans, tinplate tea cans, ceramic tea cans, glass tea cans, paper tea cans, etc. The tinplate tea cans are popular for the public because of their various styles, exquisite printing, not easy to break, and convenient shipping.
Due to factors such as price and production process, most of the iron tea cans used in the market are popular among the public because of their exquisite printing and novel style.
Tea packaging is mainly divided into small packaging and gift box packaging. Small packaging is for the convenience of customers to make tea, according to the small number of grams of packaging, to soak the tea bags.
Tea gift box packaging is the main way of tea packaging. Through the packaging materials of various materials (such as paper, wood, plastic, fabric, metal), the tea is packaged into gifts to achieve the purpose of increasing the brand awareness of tea and increasing the added value of products.
As a special kind of commodity, the packaging of tea is different from the packaging of other general commodities due to its own and objective conditions. The commonly used tea packaging methods mainly include the following.
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.
The paper box is formed by printing on white paper, gray board paper, etc. The carton package is protected from breakage 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 easy to get wet. Nowadays, the paper-plastic composite packaging box has been used to overcome the problem that the carton is vulnerable to moisture. This kind of packaging box made of plastic film layer or cardboard coated with moisture-proof coating is used as packaging material. It not only has the function of packaging the composite film bag, but also has the protection and rigidity of the carton package. If a plastic bag is used as a small bag inside, the protective effect is better.
Polyethylene, polypropylene, polyvinyl chloride and other plastic molding containers have the characteristics of generous, beautiful, and good packaging display, 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.
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 aluminum foil composite packaging bag is made of metal aluminum, and the metal barrier property of the composite plastic film is very practical and basically meets the requirements of the fragrance of the tea.
The composite film bag is packaged in a variety of forms, including a three-sided sealing shape, a self-standing bag shape, a folded shape, and the like. Packaging 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 the environmental protection requirements, bagged tea bags have been eliminated.
