The heat shrinkable film packaging machine belongs to a shrinking machine. It is a high performance shrink machine which combines sealing and contraction. Customers need to know the working principle of two in one heat shrinkable film packer before they can use more equipment. But in the use of two in one heat shrinkable film packaging machine, the phenomenon of bag breaking will occur during the shrinkage process. KSL gives the reasons:
1, seal is not sealed: two in one heat shrinkable film packaging machine is through the center folded crosslink film, through the L type sealing cutter seal. In the long-term use, there will be some shrink film on the joint and cutter, resulting in poor sealing. It is necessary to use the film removal to clean the knife. In addition, the sealing temperature is too high, which may cause the seal to be scalded, thereby the bag will be damaged in the process of shrinkage.
2. Shrinkage temperature is too high: the shrink tunnel is hermetical. The heating power is 4KW., if the temperature of the shrinkage tunnel is too high or the shrinkage time is too long. The shrink film is also ironed because of the high temperature.
POF cross-linked shrink film is the most perfect product in shrink film series, and the damage during use is rare. The range of sealing temperature and shrinkage temperature is wide, which can be suitable for most shrink packaging machines in the market, especially for high-speed packaging machines.
