Heat shrinkable labels create a new packaging trend

walking into major supermarkets, it is not difficult for us to find more and more bright packaging on the shelves, especially in the beverage area, some beverage bottle packaging that is embraced from head to toe by gorgeous plastic labels is more attractive. In fact, the use of such labels is becoming a trend to create new packaging, and has gradually spread in the packaging of food and daily chemical products. These labels are the main heat shrinkable labels of this article

landing on the market

heat shrinkable sleeve label belongs to sleeve label, which is a kind of film label printed on plastic film or plastic pipe with special ink

. When labeling, under the condition of heating (about 70 ℃), the shrink label will quickly shrink along the outer contour of the container, cling to the surface of the container, and create the effect of packaging the bottle from head to foot

in the 1970s, Japanese enterprises introduced advanced technology and made light-weight 330ml carbonated beverage bottle packaging with glass materials. Because the glass is very easy to be damaged, in order to make the packaging more safe and reliable, Japanese enterprises have effectively protected the glass packaging by using OPS (directional polystyrene) heat shrinkable sleeve label. Since then, the tide of using heat shrinkable sleeve label has been started, and its market demand has increased significantly

1982 in Chicago, USA, tylenolcapsuleextrastrength of Johnson & Johnson company was mixed with potassium cyanide, and several deaths occurred, which shocked the society. Under the influence of these events, no one bought over-the-counter drugs in the U.S. market at that time, and the development of anti tamper packaging was put on the agenda. The heat shrinkable sleeve label has proved to be an effective solution. Because its production process is not complex, manufacturers can quickly put into production after introducing equipment

1995, the British snakebite beer brand introduced a labeling technology applied to small mouth and long neck glass beer bottles for its new packaging, which was invented by siamemarnia. The promotion of new packaging has unexpectedly opened up more potential new markets. Since then, brand makers have no longer only focused on the color or surface quality of the container itself, but changed their focus from the container to the sleeve label, because the sleeve label can cover the surface of the entire container and become a unique method to create a new appearance. This is a profound change in the concept of product categories, including modified plastics, modified engineering plastics, aramid and so on

from the above three iconic and unique events, it is not difficult to see that in the past few decades, the heat shrinkable sleeve label can not be separated from the strong demand power from its birth to its promotion. In addition, with the continuous innovation of materials and technologies, today's heat shrinkable sleeve label has changed the appearance of retail packaging and brought the upgrading shelf appeal to packaging

in 2007, the heat shrinkable sleeve label accounted for 68% of the global sleeve label market, which has continued to grow in recent years. In terms of the overall form of sleeve label, its share in the global label market has increased to 7% ~ 8%, second only to wet adhesive label and self-adhesive label. It is the fastest growing category of all labels, and has been considered as the main competitor of self-adhesive label. It is estimated that the annual growth rate in the future will reach about 15%

although the time has pointed to 2011 four years later, the previous data need to be further updated. However, from our daily life, we can also clearly feel that the heat shrinkable sleeve target market is expanding, covering almost all the retail industry

click advantage and demand

the manufacturing process of heat shrinkable sleeve label is not complicated. First, the film material shall be printed in the way of inside printing (the printed graphics and text shall be properly deformed to adapt to the subsequent material shrinkage), and then a layer of white ink shall be printed to improve the scratch resistance and safe shrinkage performance, and protect the container from fading due to UV light source. Then, the printed roll material is processed into a tube and sleeved on the container to be labeled by automatic or manual methods. Finally, let the labeled container pass through the hot air or infrared channel, and use the heat to shrink the label and cling to the surface of the container

from the above production process, the heat shrinkable sleeve label has many advantages

first, the heat shrinkable sleeve label mainly adopts gravure printing (a few use flexographic printing), and the printed graphics and texts have bright color and good saturation. Because it can be used to decorate the

packaging containers closely, highlight the appearance of goods, improve the appearance decoration of goods, and produce a good shelf effect; Second, in the labeling process, the label and container can be integrated without the use of adhesive, which can realize the large-scale wiring operation of commodities and greatly reduce the production cost; Thirdly, all the gaps under the base are filled with cement slurry. The internal printing method can protect the pictures and enhance the wear resistance of the heat shrinkable sleeve label in the transportation and sales links

from the perspective of functional requirements, the heat shrinkable sleeve label has the characteristics of moisture-proof customized engineering polymer formula, anti-corrosion, impact resistance, tear resistance, tasteless and non-toxic; It can play an anti-counterfeiting role and provide effective UV protection for photosensitive products; Protect consumers from accidental injury caused by broken or broken containers. Most importantly, this label can be recycled and has significant advantages in cost saving and environmental protection

however, there are many difficulties in the design of heat shrinkable sleeve. From the design point of view, the relationship between the deformation rate of the pattern and the shrinkage rate of the substrate, and the relationship between the shrinkage of the substrate, ink and auxiliary materials are all issues that designers need to focus on. These problems are directly related to the choice of raw materials

as one of the two important raw materials for the production of heat shrinkable sleeve, PVC heat shrinkable film is widely used in the market. Now most enterprises in China are not equipped with friction and wear testing machines. This kind of film has many advantages, such as waterproof, fire-resistant, high transparency, high gloss, high shrinkage (70%), but it is easy to produce toxic gas when burning, which is not conducive to environmental protection. As a new type of material, OPS heat shrinkable film is a body fitted

packaging material that meets the requirements of environmental protection. It has many advantages, such as high strength, high rigidity, good gloss, high shrinkage (65%), and meets the food hygiene standards. However, since there are not many enterprises producing this film in the market, the market demand for this film can not be fully met

for ink, its quality directly affects the printing effect of heat shrinkable sleeve logo. Practice has proved that UV flexo printing ink is a very good choice. Its biggest advantage is that it can achieve high color intensity through curing and drying, which also brings great challenges to the traditional gravure printing ink

in addition to improving the quality of raw materials, high-speed labeling equipment is also essential. Only the perfect combination of technology and raw materials can create more markets for heat shrinkable sleeve labels
