Common questions
Why are Stayflats® mailers better than standard envelopes for e-commerce shipping?
Stayflats® mailers feature rigid.036 chipboard construction that prevents bending and protects contents from crushing during transit. Unlike padded or bubble mailers, they maintain a professional flat appearance, reduce dimensional weight charges, and require no additional stiffeners or reinforcement.
Do these mailers work for items heavier than typical mail?
Yes. The.036 chipboard provides structural integrity for photos, documents, vinyl records, trading cards, and lightweight merchandise up to several pounds. The tab-lock closure remains secure throughout shipping, though actual weight limits depend on your carrier's dimensional weight pricing.
Are these mailers recyclable and environmentally friendly?
Absolutely. Made from 100% recyclable kraft chipboard, these mailers support sustainable shipping practices. Many customers appreciate the natural kraft appearance for eco-conscious branding while delivering protection.
What's the difference between.036 chipboard and lighter alternatives?
The.036 thickness provides maximum puncture and bend resistance while remaining lightweight enough to avoid excessive postage surcharges. Lighter alternatives compromise protection; thicker versions increase weight and cost without additional benefits for flat items in the 9 3/4" x 12 1/4" size.
