Interpretation of new clothes
With the rapid changes in the tea market, the teabag industry is undergoing a revolutionary transformation. As the awareness of teabags is deepening, the rumors of teabags, which are inferior teas, are not broken.
The triangular tea bag is also very similar to the horns because of its shape and shape. Its personalized appearance brings a beautiful visual effect. People's love for triangular tea bags can be seen from the growing popularity of triangular tea bags in the teabag market. The three-dimensional transparent, sleek and individualized shape, the diverse materials of different styles and characteristics make the "new clothes of tea".
Due to the shape and volume limitation of traditional tea bags, the tea leaves must be crushed and then filled, so the end of the tea leaves in the traditional tea bags cannot be discerned by the naked eye. The triangular tea bag can maintain its original shape because of its large accommodation space. The brewed tea leaves are stretched in the tea bag, and the transparent outer coat makes the tea taste better.
From the point of view of the water contact area of the tea bag, the triangular tea bag can accommodate a larger surface area of hot water than the triangular tea bag of the same volume. The surface area of a traditional tea bag in contact with water is one-half of the total area, while the surface area of the triangular tea bag in contact with water is three-quarters of the total area. It can be seen that the release efficiency of tea leaves rises as the area of the tea bag contacts the water increases.
The most obvious difference between a traditional tea bag and a triangular tea bag is the packaging material. Traditional tea bags are mainly made of filter paper, while triangular tea bags are mainly made of non-woven fabrics and mesh fabrics. In addition to the material is not transparent enough, the filter paper tea bag can not maintain the original "form" after several times of brewing, and the tea in the cup is not clear and transparent at first. It is slightly turbid and has no beauty; from the perspective of tea-seekers, this effect does not have the conditions for appreciation. The other non-woven material used for the triangular tea bag material still has no effect on the mesh material; the non-woven material triangle tea bag can be easily hand-teared, and its flexibility is not good. In the mesh material triangle tea bag; from the visual effect of tea brewing, it is even less transparent than the mesh material triangle tea bag. The triangular tea bag of mesh material, after several times of brewing, shows the clarity and firmness of the display; whether it is from the shape of tea standing in the tea bag, or the tea fragrance floating through the mesh cloth, Appreciate the appreciation of tea drinkers.
The main difference between the two materials of non-woven fabric and mesh fabric is that the manufacturing process is different. The mesh cloth is interwoven by one yarn and is woven by plain weave. The non-woven fabric is also called "non-woven fabric". It is a fabric formed without spinning fabric, and only the short fibers or filaments are woven. Oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Both materials are derived from raw materials: nylon, PET, PLA (corn fiber). Compared with the non-woven fabric, the three materials of the mesh are more obvious from the naked eye and from the touch.
Three mesh differences
The first is nylon (PA) mesh, the raw material used is nylon 6 monofilament, also known as PA6, nylon 6, polyamide 6. Nylon mesh originated in Japan, among the three packaging materials, it was the earliest packaging material for triangular tea bags. Because of its good flexibility, high softening point, heat resistance, aseptic, soft silky and other advantages are widely used in triangular tea bags. From the naked eye, there is a silky smooth visual sense; the same is true with a hand touch. The touch is more silky and delicate.
Followed by PET mesh, the raw materials used are PET, also known as polyester, polyester resin. The PET material has a high degree of firmness. The daily thickness of the 45um (micron) PET mesh is better than the 60um thick nylon mesh, and the water absorption is not strong, and the water absorption is only 0.1%. PET has high transparency, can block ultraviolet rays, has good gloss, is non-toxic, tasteless, hygienic, and has good safety. It is widely loved by major tea-based merchants. PET mesh is therefore called the evolution of nylon mesh. Upgraded version; can be used directly in food packaging. From the naked eye, PET mesh has higher gloss than nylon mesh and corn fiber mesh; three material meshes are arranged under the light for appreciation, and only the gloss can clearly identify the PET mesh. . In terms of touch, the PET mesh feels more elastic than nylon mesh and corn fiber mesh.
Finally, the corn fiber (PLA) mesh cloth, which is made of PLA, also called corn fiber, polylactic acid fiber, is made from corn, wheat and other starches, fermented into lactic acid and then polymerized and spun. synthetic fiber. The most obvious characteristic of corn fiber mesh is environmentally friendly degradability; the material is soft, smooth, strong, moisture absorbing and breathable. The processed products have silky luster and comfortable skin feel and feel, and have many advantages such as good drape, good taking performance, good heat resistance and anti-UV function; it is the top material of the current triangular tea bag. From the visual effect, the corn fiber mesh has no similar visual sense of nylon mesh, and there is no eye-catching gloss of PET mesh. Although the feel of the nylon mesh is not smooth and silky, it is not as good as the stretch of the PET mesh. The most obvious difference between the three mesh fabrics is that the corn fiber mesh can be easily hand-teared, while the nylon mesh and the PET mesh do not have the characteristics of hand-tear, and the material is extremely tough. Due to its "environmentally degradable" characteristics, corn fiber mesh has the highest voice among the three mesh fabrics. It can be seen that people's awareness of environmental protection is constantly improving with the development of society. In terms of environmentally friendly degradability, nylon mesh and PET mesh can also be degraded, but the degradation rate is not comparable to the degradation rate of corn fiber mesh.
In short, the three meshes have their own merits. As a food grade packaging material, the mesh material is suitable for a wide range of applications. In addition to being used for tea packaging materials, it can also be used for the packaging of several types of tea such as fruit tea, herbal tea, and health tea, and many other merchants use it for Chinese herbal medicine. The package is boiled. It can be seen that the mesh triangle package has a high degree of rigidity and strong permeability. The discerning merchants can choose to purchase according to the characteristics of the three mesh fabrics. The three meshes have their own advantages and characteristics; there is no so-called optimal and worst, and the mesh that is most suitable for the performance of its own products is selected, which is the so-called best mesh. The tea with the "new clothes" is made with the smooth and radiant quality coat, with the long history and variety of Chinese tea as the internal raw material, relying on the profound cultural heritage of Chinese tea; it is bound to be in the tea market. Stable foundation.
