Until the shrink bag completely clings to the product Tips: If it is used for DIY package, the heat gun can not stay in the same area for too long. It is necessary to keep moving the heat gun to avoid excessive heat expansion. Ordinary household hair dryers can't work because it can't heat up to the 340 °F required for shrinkage!!!

Tools needed to complete the shrinkage: A heat gun or a professional Tunnels Heat Shrink Packing Machine, and a heat sealer.
