Frequently Asked Questions
Are these boxes recyclable?
Most of the corrugated boxes reviewed are recyclable corrugated cardboard (many list ECT-32 grade). They are generally accepted in curbside recycling programs—remove any tape or non-paper labels first. Polyethylene mailers are typically not curbside recyclable; check local recycling guidelines or mail-back programs.
Which box size should I choose for reducing postage costs?
Choose the smallest box that fits your product plus minimal cushioning. Lightweight, low-volume boxes reduce dimensional and actual weight. When possible use single-layer corrugated boxes with thin internal padding rather than oversized boxes with heavy fill.
Are poly mailers an eco-friendly choice?
Poly mailers protect against moisture and reduce package size, which can lower shipping emissions, but most are made of polyethylene and aren’t accepted in curbside recycling. If environmental impact is a priority, prefer recyclable corrugated boxes or seek compostable/film-free mailer options from suppliers.
