The heat-shrinkable label has strong adaptability, and can be used for surface decoration and decoration of packaging containers such as wooden paper, metal glass, ceramics, etc. The main application areas are packaging and decoration of food, beverage, health care products, chemical products, etc.
1. Heat shrinkable film label and its characteristics
Heat shrinkable film label is a film label printed on plastic film or plastic tube with special ink. In the process of labeling, the shrink label will quickly shrink along the outer wheel of the container when heated and adhere to the surface of the container. .
1. Advantages of heat shrinkable label packaging.
(1) Heat-shrinkable packaging can package special-shaped products that are difficult to package by general methods, such as vegetables, meat and poultry, aquatic products, toys, gadgets, small electronic products, etc.
(2) The heat-shrinkable film has high transparency, so the label has bright color and good gloss.
(3) The heat shrinkable film adheres to the product after shrinking, the packaging is compact and the appearance of the product can be displayed, and the packaged product is beautiful.
(4) The heat-shrinkable film can provide 360-degree all-round decoration to the packaging container, and can print product information and other product information on the label, so that consumers can understand the performance of the product without opening the package.
(5) The shrink film has good abrasion resistance and high strength, ensuring that it can bear the weight of the content. Printing is printed in the film (the picture and text are in the film sleeve), which can play the role of protecting the imprint, and the label has better wear resistance.
(6) The heat-shrinkable packaging has good sealing, moisture-proof, anti-fouling and anti-rust effects, which can prolong the shelf life of food, easy to store, easy to stack in the open, and save the storage area.
(7) The heat shrinkable packaging process and equipment are simple, and the heat sealability is good. There is no need to use adhesives when labeling.
(8) The heat shrink packaging can also use the on-site shrink packaging method to pack bulky products, such as rowing boats and small cars, etc. The shrink film itself has a good slowness; neutrality and toughness can prevent vibration and vibration during transportation. The product is damaged by impact, and no other packaging materials can be used during transportation. The packaging cost is low, and the cost is lower than that of adhesive labels.
(9) Now the shape of the packaging container is unique, and there are more and more individualized designs. The heat shrinkable film label can clearly show the outer surface contour of the packaging container.
(10) The residual amount of solvent is low, and the residual amount of solvent will be kept at about 5mg / m2, which is far lower than other printing methods.
(11) The heat shrinkable film as a label saves forest resources, reduces costs, is hygienic, and is easy to use.
2. Disadvantages of heat shrinkable film labels.
(1) It is necessary to consider that the shrinkage of the graphic image is the same as that of the shrink film in order to accurately reproduce.
(2) The ink used in the printing of heat shrinkable film labels must also have a certain shrinkage rate in order to accurately reproduce the graphics.
(3) Since the heat shrinkable film label must be shrunk during the printing process, and the barcode can only be read by accurate reproduction, it must undergo strict design and printing quality control, otherwise the shrinkage and deformation of the pattern will cause the barcode quality to be unqualified or impossible Read.
(4) The printability of most heat-shrinkable films is not very good, and pre-press pretreatment is required.
