How to choose pearlescent film bubble bag and kraft paper bubble bag?

In fact, in terms of shockproof effect, both kraft paper bubble bags and poly bubble mailers depend on the thickness of the bubble layer. The kraft paper bubble bag and poly bubble mailer are both single-layer airbags, and the shockproof effect is not comparable. As far as the outer material is concerned, good kraft paper is relatively hard, while the hardness of ordinary kraft paper is equivalent to that of plastic film, but the cost of good kraft paper is higher. Therefore, when purchasing, users should consider which bubble bag to choose according to their own needs.
