A heat shrinkable film label is a film label printed on a plastic film or plastic tube using a special ink. During the labeling process, the shrink label quickly shrinks along the outer wheel of the container when heated, and adheres to the surface of the container.
1. Advantages of heat shrink label packaging
(1) Heat shrinkable packaging can package shaped products that are difficult to package in general methods, such as vegetables, meat and poultry, aquatic products, toys, gadgets, and small electronic products.
(2) The heat shrinkable film has high transparency, so the label has bright color and good gloss.
(3) After shrinking the heat shrinkable film, the product is compact and can display the appearance of the product, and the product after packaging is beautiful.
(4) The heat shrinkable film can provide 360-degree all-round decoration to the packaging container, and can print product information such as product description on the label, so that the consumer can understand the performance of the product without opening the package.
(5) The shrink film has good wear resistance and high strength, ensuring the weight of the contents. The printing belongs to the film printing (the image is in the film sleeve), which can protect the imprint and the label has better wear resistance.
(6) The heat shrinkable packaging has good sealing, moisture proof, antifouling and anti-rust effects, which can prolong the shelf life of the food, facilitate storage, facilitate open storage, and save warehouse area.
(7) The heat shrink packaging process and equipment are relatively simple, the heat sealing property is good, and the label is not required to be used for labeling.
(8) Heat shrinkable packaging can also be used to package bulky products by on-site shrink packaging methods, such as rowing boats and cars. The shrink film itself has better retardation; neutrality and toughness, which can prevent vibration and transportation during transportation. Impact and damage to the product, no other packaging materials can be used for transportation, the packaging cost is low, and the cost is lower than that of the self-adhesive label.
(9) Nowadays, the packaging container has a unique shape and a personalized design, and the heat-shrinkable film label can clearly show the outer surface contour of the packaging container.
(10) The solvent residual amount is low, and the residual amount of the solvent is kept at about 5 mg/m 2 , which is far lower than other printing methods.
(11) The heat shrinkable film is used as a label to save forest resources, reduce costs, sanitation, and ease of use.
2. Disadvantages of heat shrinkable film labels
(1) It is necessary to consider that the shrinkage rate of the graphic image is the same as the shrinkage rate of the shrink film, so that it can be accurately reproduced.
(2) The ink used in the label printing of the heat shrinkable film must also have a certain shrinkage rate in order to accurately reproduce the graphic.
(3) Since the heat shrinkable film label must be shrunk during the printing process, and the bar code can only be read accurately, it must undergo strict design and print quality control. Otherwise, the pattern will shrink and deform, which will cause the barcode quality to be unqualified or unreadable.
(4) The printing suitability of most heat shrinkable films is not very good, and prepress pretreatment is required.
