Gas barrier, the addition of plasticizer can improve cold resistance and impact strength, the use effect is better, the cost is lower, can be preferred, the thickness range is between 0.10-0.25mm.
The substrate is also a major component of the blister package. As with plastic films, the size, shape, and mass (weight) of the package must be considered when selecting.
