Frequently Asked Questions
Are these mailers recyclable or eco-friendly?
Most corrugated boxes listed are recyclable; check local recycling rules for coatings. Some tapes and poly mailers use eco-conscious materials or are recyclable in specific programs—confirm packaging labels before recycling.
How do I know if a mailer is strong enough for my product?
Match the mailer to the product: soft items can use poly mailers if wrapped, fragile or heavy items need corrugated boxes with cushioning. Look for reinforced edges, ECT ratings on boxes, and thicker polyethylene or higher-mil spec for poly bags.
Does wider tape make a big difference?
Yes. Wider tape (3") covers more seam area per pass, often improving hold and reducing the number of strips needed. However, tape quality and adhesive consistency are equally important—choose tapes described as tear-resistant and reliable across temperatures.
