Do these mailers require additional stiffeners or inserts?
No. The.028 chipboard thickness provides sufficient rigidity to protect contents without additional reinforcement, reducing material costs and assembly time.
Will the self-seal closure hold securely during shipping?
Yes. The peel-and-seal adhesive strip creates a permanent, tamper-evident seal that withstands standard shipping conditions and handling without reopening.
Are these mailers puncture-resistant?
Yes. The.028 kraft chipboard material resists punctures from handling equipment and shipping processes, protecting delicate items like photos and documents.
Can I reduce postage costs with these mailers?
Yes. The lightweight design minimizes dimensional weight charges when calculated by carriers, and no additional stiffeners are needed, reducing your per-unit shipping cost compared to heavier alternatives.
