購買須知：
要根據產品不同質量不同材質不同包裝效果要求選擇不同的熱收縮包裝膜,
其實熱收縮包裝膜的選擇并不是很繁瑣，只要掌握熱收縮包裝膜的收縮率,厚度適中即可。
熱收縮包裝膜影響產品熱收縮包裝的效果的主要因素就是收縮率，收縮率越大越好。
購買熱收縮包裝機機時，也要注意選好風機。同時，更要注重熱風流通管道系統結構的布局。
當風機工作時，能將上下加熱的溫度攪送均勻，從而達到理想的效果。
Guidance notes:
Depending on the different quality of the product, different packaging effects are required to select different heat shrinkable packaging films.
In fact, the choice of heat shrinkable packaging film is not very complicated, as long as the recovery of heat shrinkable packaging film is better, the thickness is moderate.
The main factor that affects the effect of heat shrink wrap is the shrinkage rate. The bigger the shrinkage, the better.
When buying a heat shrinkable packaging machine, you must first choose the fan. At the same time, it should pay more attention to the layout of the system structure of the hot air circulation pipeline.
When the fan is working, the temperature of the upper and lower heat can be stirred evenly to achieve the desired effect.
