How to Choose Suitable Tea Packaging Machine? Why does tea need to be packaged?
First understand the benefits of tea packaging:
(1) Moisture-proof
The moisture in tea is a means of tea biochemical changes, and low moisture content is conducive to maintaining the quality of tea. The water content in tea should not exceed 5%. Long-term storage of 3% is better. Otherwise, the ascorbic acid in the tea is easily decomposed, and the color, aroma and taste of the tea will change, especially at higher temperatures, the rate of deterioration will be accelerated. Therefore, the tea packaging machine can be used for moisture-proof packaging during packaging, such as aluminum foil or aluminum foil evaporation film as the basic material of the composite film.
(2) Antioxidant
The oxygen content in the packaging of the tea bag packaging machine has been over-processed, which will cause the oxidative deterioration of certain components in the tea. For example, ascorbic acid is easily oxidized to deoxyascorbic acid. In addition, it reacts with amino acids to cause pigment reaction, thereby impairing the taste of tea. Therefore, the oxygen content of the tea container must be effectively controlled below 1%. Inflation or packaging can be used to reduce the presence of oxygen. Packaging technology involves putting tea leaves in soft and flexible film packaging bags. In the packaging process, the air in the bag is removed, which will produce a certain degree, and then the sealing method is sealed; the air filling technology is to inject inert gas such as nitrogen while expelling the air to protect the color, aroma and taste of the tea. No change, keep the original quality.
(3) Gas barrier
The aroma of tea is easy to lose and is easily affected by external odors. In particular, the residual solvent of the composite film and the smell of electric soldering iron treatment and heat sealing treatment will affect the taste of tea and they will affect the aroma of tea. Therefore, the tea bag packing machine should avoid the fragrance of the packaging and the absorption of peculiar smell from the outside when packaging the tea. Tea packaging materials must have certain barrier properties.
(4) High temperature resistance
Temperature is an important factor that affects the quality of tea. The temperature difference is 10°C, and the chemical reaction rate is 3 to 5 times. Tea will aggravate the oxidation of substances at high temperatures, leading to a rapid reduction of effective substances such as polyphenols and accelerating the deterioration of quality. The storage temperature of tea leaves is better than 5℃. From 10 to 15°C, the color of tea leaves is slower. The color effect can also be maintained: when the temperature exceeds 25°C, the color of the tea leaves will change rapidly. Therefore, tea leaves are suitable for storage at low temperatures.
(5) Shadow
Light can promote the oxidation of chlorophyll and lipids in tea, increase the odorous substances such as valeraldehyde and propionaldehyde in tea, and accelerate the aging of tea. Therefore, the small tea bag machine must be protected from chlorophyll when making tea in the tea bag packaging machine. Photocatalytic reactions occur in other components, such as lipids. In addition, ultraviolet light is also an important factor in the deterioration of tea.
2. What kinds of tea bag packaging machine are divided into?
As a special kind of commodity, tea is restricted by its own and objective conditions. The packaging of tea is also unique. The basic requirements for the most packaging of tea are relatively strict, such as moisture-proof, anti-oxidation, anti-high temperature, shading, and gas resistance. The packaging of tea is different from the packaging of other general commodities. The commonly used tea packaging methods mainly include the following:
1. Metal can tea packaging machine
The metal can packaging has excellent anti-breakage, moisture-proof and sealing properties, making it an ideal packaging for tea. Metal cans are generally made of tin-plated sheet steel. The cans are in square and cylindrical shapes. There are two types of lids: single-layer lid and double-layer lid. From the perspective of sealing, there are two types of general cans and sealed cans. In terms of packaging technology, generally cans can be sealed with deoxidizer packaging to remove oxygen in the packaging. Sealed tanks are mostly inflated and vacuum packing machine. The protection of metal cans to tea leaves is better than that of composite films, and the appearance is beautiful and noble. Its disadvantages are the high packaging cost and the high weight ratio of the packaging to the product, which increases the transportation cost. The exquisitely designed metal can is suitable for the packaging of high-end tea.
2. Paper box tea packaging machine
The carton is formed after printing with white paper, grey board paper, etc. The carton packaging prevents easy breakage and has excellent shading performance. In order to solve the volatilization of the aroma of tea packaged in cartons and avoid the influence of external odor, the tea is generally packaged in polyethylene plastic bags and then put into cartons. The disadvantage of carton packaging is that it is susceptible to moisture. In recent years, paper-plastic composite packaging boxes have emerged, which overcomes the problem of dampness of the carton. This kind of packaging material is made of cardboard with an inner layer of plastic film or a moisture-proof coating. The packaging box not only has the function of composite film bag packaging, but also has the protective and rigid properties of carton packaging. If plastic bags are used inside to make small packaging bags, the protective effect is better.
3. Plastic molding container tea packing machine
Polyethylene, polypropylene, polyvinyl chloride and other plastic molded containers are generous, beautiful, and have good packaging and display effects, but their sealing performance is poor. They are mostly used as outer packaging in tea packaging, and composite film plastic bags are used in the packaging. Package.
4. Compound film tea bag packing machine
Plastic composite film has many advantages, such as light weight, not easy to break, good heat sealability, and reasonable price, and it is widely used in packaging. There are many kinds of composite films used for tea packaging, such as moisture-proof cellophane/polyethylene/paper/aluminum foil/polyethylene, biaxially stretched polypropylene/aluminum foil/polyethylene, polyethylene/polyvinylidene chloride/polyethylene, etc. The composite film has excellent gas barrier properties, moisture resistance, fragrance retention, and odor resistance. Since most plastic films have a light transmittance of 80% to 90%, in order to reduce the transmittance, UV suppression can be added to the packaging material or printing or coloring can be used to reduce the light transmittance. In addition, a composite material based on aluminum foil or vacuum aluminized film can be used for light-shielding packaging. There are various packaging forms of composite film bags, including three-sided sealing, self-supporting pouch, folding and so on. Because the composite film bag has good printability, using it as a sales packaging design has a unique effect on attracting customers and promoting tea sales.
5. Paper tea bag packaging machine
Paper bag small tea packing machine is also called tea bag, which is a kind of bag packaging with thin filter paper as the village material, and the paper bag is put into the tea set when it is used. The purpose of packaging with filter paper bags is mainly to increase the extraction rate, and also to make full use of the tea powder in the tea factory. Because teabags have the advantages of fast brewing, clean and hygienic, standard dosage, can be mixed for drinking, convenient for slagging, easy to carry, etc., they adapt to the fast-paced life needs of modern people and are very popular in the international market. In the early days, teabags generally had a bag line to meet the convenience of multiple steeping. Due to environmental protection requirements, teabags without a bag line are now becoming popular.
Teabags can be divided into the following types:
1.Automatic filter bag tea packing machine
2.Pyramid tea bag packing machine
3.Pyramid automatic tea bag packing machine for inner and outer tea bag
4.Drip bag packaging machine
5.High speed tea bag packing machine with outer envelope
3. How to choose a suitable tea bag packaging machine?
1. First determine which products to pack (oolong tea, black tea, green tea, white tea, yellow tea, tea powder-teabag). Is it granular or powdered tea? To package the inner film or the outer bag, or the integrated packaging of the inner and outer bags.
2. The size and packaging weight of the bag, and products with a large difference in external dimensions should be separated and packaged by the machine as much as possible. To
3. To determine your own output, you can choose tea sachet packing machine with different speeds, or how many sets of equipment you need to purchase.
4. According to the packaging materials, choose different types of tea pouch packing machine.
5. Choose branded tea bag packing machine companies as much as possible, and the quality is guaranteed. Choose models with mature technology and stable quality to make packaging faster and more stable, with low energy consumption, low manual work, and low waste rate.
6. If there is an on-site inspection, pay attention to the big aspects, but also to the small details. The details often determine the quality of the whole machine. Carry the sample test machine that needs to be packed as much as possible.
7. In terms of after-sales service, it has a good reputation. Good after-sales service attitude and timely service are especially important for the production of tea enterprises. For example, during the peak season of spring tea and autumn tea, if the tea packaging machine has a problem in production and cannot be solved immediately, the loss can be imagined.
8. Tea bag packing machine trusted by peers can be given priority.
9. Try to buy automatic tea packing machine that is simple in operation and maintenance, complete in accessories, and fully automatic continuous feeding, which can improve packaging efficiency and reduce labor costs, which is suitable for the long-term development of tea enterprises
