The market prospect of shrink wrap label is promising

shrink wrap label is a kind of film set label printed on plastic film or plastic pipe. It has the following characteristics:

1. The shrink film sleeve label is easy to process, sealed and pollution-proof, and has good commodity protection

2. The film sleeve is close to the commodity, the packaging is compact, and the commodity shape can be displayed, so it is suitable for irregular commodities that are difficult to package

3. When labeling, there is no need to use adhesive, and the same transparency as glass can be obtained

4. It can provide 360 all-round decoration for the packaging container, and print the product description and other commodity information. The power is to brush it on the label through the piston itself, so that consumers can understand the performance of the product without opening the package

5. The printing of shrink film cover label belongs to film inner printing (pictures and texts are on the inner side of the film cover), which can protect the imprint, and the label has better wear resistance

shrink labels have strong adaptability. They can be surface mounted on wooden, paper, metal, glass, ceramics and other packaging containers, which can cause serious deformation and decoration. They are widely used in the packaging and decoration of food, daily chemical products and chemical products, such as various beverages, cosmetics, children's food, coffee and so on. In the field of drug labels, paper is still the main substrate, but the development of film packaging has become increasingly rapid

shrink film sleeve labels are becoming more and more popular in the market because they can combine high-quality patterns with distinctive shapes

film materials:

the materials for making shrink film sleeve labels mainly include PVC (polyvinyl chloride) film, pet (polyester) film, PETG (modified polyester) film, OPS (oriented polystyrene used to be mechanically locked) film, etc. Its properties are as follows:

C film

PVC film is the most widely used film material at present. It has low price, large temperature contraction range and low requirements for heat source. The main processing heat source is hot air, infrared or a combination of the two. However, PVC is difficult to recycle and produces toxic gas when burning, which is not conducive to environmental protection, and has been banned in Europe and Japan

s film

as a substitute for PVC film, OPS film has been widely used. It has good shrinkage and is also conducive to environmental protection. The domestic market of this product is in short supply. At present, high-quality OPS mainly depends on imports, which has become an important factor restricting its development

tg film

petg copolymer film is not only conducive to environmental protection, but also can pre adjust the shrinkage 3 In line with ergonomics: this series of experimental machines regardless of the height and width of the experimental space. However, due to the excessive shrinkage, it will also be limited in use

t film

pet film is an internationally recognized environmental friendly heat shrinkable film material. Its technical index, physical properties, application range and application method are close to PVC heat shrinkable film, but the price is cheaper than PETG. It is the most advanced unidirectional shrinkable film at present. The horizontal shrinkage rate is 70%, the longitudinal shrinkage rate is less than 3%, and it is non-toxic and pollution-free. It is the most ideal material to replace PVC

in addition, the heat shrinkable film tube is also the material for the production of shrinkable film sleeve labels, and it can be formed at one time without stitching in production. Compared with horizontal flat film, the cost of producing shrink film sleeve labels with heat shrinkable film tubes is lower, but it is difficult to print on the surface of the tube. At the same time, the graphics and text of the heat shrinkable film tube label can only be printed on the film surface, which is easy to be worn during transportation and storage, thus affecting the packaging effect

1. Print

Print on selected film. At present, the printing of shrink film cover mainly adopts gravure printing, using solvent based ink, followed by flexographic printing. With the development of flexographic printing technology, the printing color is bright and clear, which is comparable to gravure printing, and has the thickness and high gloss of gravure printing. In addition, flexo printing uses water-based ink, which is more conducive to environmental protection

2. Slitting

use a high-performance slitting machine to Slitter the printed roll film material longitudinally, and at the same time, treat the edge of the film to make it smooth, flat and non crimping. When using the slitter, care should be taken to avoid heating the blade, because the heated blade will wrinkle the slitted part of the film

3. Suture

the longitudinally cut film is sewn in the center with a sewing machine, and the nozzle is bonded to form the film sleeve required for packaging. The material allowance required for stitching depends on the stitching accuracy and the skill of the operator. The maximum allowable amount of stitching is 10mm, usually 6mm

4. Horizontal cutting

wrap the film sleeve outside the commodity, and use the slitter to cut horizontally according to its packaging size. Under proper heating temperature, the length and width of the shrink film will shrink sharply (15% - 60%). Generally, the film size is about 10% larger than the maximum size of the commodity

5. Thermal shrinkage

is heated by hot channels, hot ovens or hot-air lances. At this time, the shrink label will quickly shrink along the outer contour of the container, closely fit with the outer contour of the container, and form a label protective layer completely consistent with the shape of the container

in the production process of shrink film sleeve label, each process should be closely tested by a special detector to ensure the production accuracy

scope of application:

shrink labels have strong adaptability. They can be used for surface decoration and decoration of wooden, paper, metal, glass, ceramics and other packaging containers. They are widely used in the packaging and decoration of food, daily chemical products and chemical products, such as various beverages, cosmetics, children's food, coffee and so on. In the field of drug labels, paper is still the main substrate, but the development of film packaging has become increasingly rapid. At present, the key to the development of shrink film labels is to reduce costs. Only in this way can we improve competitiveness and strive for greater market share
