(6) Heat-shrinkable packaging has good sealing, moisture-proof, anti-fouling and rust-preventing effects, which can prolong the storage period of foods, facilitate storage, facilitate stacking in the open air, and save storage space.
(7) The heat shrink packaging process and equipment are relatively simple, and the heat sealability is good. No adhesive is required for labeling.
(8) Shrink-wrapped packaging can also use in-situ shrink packaging methods to package bulky products such as racing boats and cars. Shrinking film itself has better cushioning; neutrality and toughness; it can prevent vibration during transportation and Damage to products due to impact, transportation can no longer use other packaging materials, low packaging costs, the cost is lower than the adhesive label.
(9) Heat shrinkable film as a label to save forest resources, reduce costs, hygiene, and ease of use.
2. The disadvantage of heat shrinkable film
(1) It is necessary to consider that the contraction rate of the graphic image is the same as the shrinkage rate of the shrink film, and can be accurately reproduced.
(2) The ink used in the thermal shrink film label printing must also have a certain shrinkage rate in order to accurately reproduce the graphic.
(3) Since the heat shrinkable film label must be shrinked during the printing process, and the barcode can be read only with accurate reproduction, it must undergo strict design and print quality control. If the pattern shrinks and deforms, it will cause the barcode quality to be unqualified or unreadable.
(4) The printability of most heat-shrinkable films is not very good and requires prepress prepress.
