Heat shrinkable packaging is a packaging method widely used in commodity packaging. It can be used to package various types of products. It has the characteristics of transparent container, sealing, moisture-proof, etc. Its process and equipment are simple, packaging costs are low, and packaging methods are diverse. Favored by businesses and consumers. Heat shrinkable labels are part of the label market and are used in heat shrinkable packaging. They are growing rapidly and their market share continues to expand. It is expected that the annual growth rate can be maintained at about 15%, far exceeding the annual growth rate of about 5% in the general label market, with huge development potential and becoming the biggest bright spot in the label industry.
Heat shrinkable labels are highly adaptable, and can be used for surface decoration of packaging containers such as wood, paper, metal glass, and ceramics.
Heat shrinkable film label is a kind of film label printed on plastic film or plastic tube with special ink. In the process of labeling, when heated, the shrink label will quickly shrink along the outer wheel of the container and adhere to the surface of the container.
1. The 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, small tools, small electronic products, etc.
(2) The heat shrinkable film has high transparency, so the label has bright color and good gloss.
(3) After shrinking, the heat shrinkable film is close to the product, 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 a 360-degree all-round decoration to the packaging container. And product information such as product descriptions can be printed on the label, so that consumers can understand the performance of the product without opening the package.
(5) The shrink film has good wear resistance and high strength to ensure that it can bear the weight of the contents. Printing belongs to the inner printing of the film (the picture and text are in the film sleeve), which can protect the imprint, and the label has better wear resistance.
(6) Heat shrinkable packaging has good sealing, moisture-proof, anti-fouling and rust-proof functions, which can prolong the shelf life of food and facilitate storage. Easy to store in the open air. Save warehouse space.
(7) The heat shrinkable packaging process and equipment are relatively simple. Good heat sealability, no adhesive is required for labeling.
(8) Heat shrink packaging can also use on-site shrink packaging methods to package bulky products, such as racing boats and cars, etc. The shrink film itself has good softening; If the product is damaged by impact, other packaging materials can be no longer used during transportation. The packaging cost is low, and the cost is lower than that of self-adhesive labels.
(9) Now the shape of the packaging container is unique, and the design of individuality is increasing day by day, and the heat shrinkable film label can clearly show the outline of the outer surface 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.
(1 1) Heat shrinkable film as a label saves forest resources, reduces costs, is hygienic, and is easy to use.
2. Disadvantages of heat shrink film labels.
(1) It is necessary to consider that the shrinkage rate of the graphic image is the same as that of the shrink film in order to reproduce it accurately.
(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 quality of the barcode will be unqualified or unreadable after the pattern shrinks and deforms.
(4) The printability of most heat shrinkable films is not very good, and pre-printing is required.
