Buying Guide: Grey Poly Mailers – What To Consider
Choosing the right grey poly mailers depends on your product mix, shipping volumes, and branding goals. The following perspectives help balance cost, protection, and efficiency:
- Size variety: Maintain a mix of small, medium, and large mailers to minimize DIM weight and avoid using oversized packaging for tiny items.
