    Adjustment method:

   1. in order to achieve a perfect shrinkage bottle type, the position of the blow port must be properly adjusted to allow the bottle to shrink for a certain period of time and temperature;

   2. the use of better quality pressure reducing valve, or high-end pressure reducing valve;

   3. let the label supplier provide a label with stable shrinkage and use it;
