1. Heat-effect free to the contents .Reduce waste during packaging process, and protect the products. Because the cold-seal glue-coated packaging materials are being done under a cold state，unlike composite film which needs to be sealed in a heated state, so for heat-sensitive substances such as chocolate, etc., cold-seal have a good protective effect.
2.Good for materials which are not suitable for hot seal.The shrinkage of the material will not be caused by heat, and a flat and beautiful sealing shape can be obtained, and as there is no heat effects, the contents can be tightly wrapped to keep the minimum distance between the packaging material and the contents.
3.The speed of packaging has greatly increased the production efficiency. In the process of hot seal, the sealing can only be achieved by controlling three process parameters,which are heat sealing temperature,heat sealing time,and heat sealing pressure. As for cold seal, only sealing presure is to be controlled.
The speed changes of the packaging production line have no effects on the seal.Therefore, the sealing time can be shortened in a large range, and compared with heat-sealing materials, the production speed can be increased by 50% to 100%.
4. Good cold resistance, even at -20°C, it can also maintain the same sealing strength as that of normal temperature.
5. It can reduce the maintenance costs of packaging equipments and reduce energy waste. And it is safer to operate the packaging equipments.
6. Of course, cold-seal plastic packaging materials also have limitations. Its sealing strength is not very big, generally only 2-4N/15mm, and can only be used for light packaging. In addition,it can only in the form of film rolls.
