The Boxery highlights flat mailers as a lightweight shipping alternative for documents, apparel, and inserts as carriers expand dimensional weight pricing.

Lyndhurst, United States, September 27, 2026 -- LYNDHURST, NY — The Boxery, an online supplier of packaging and shipping materials, is highlighting flat mailers as a practical option for sellers looking to reduce dimensional weight charges on packages containing documents, apparel, and promotional inserts. The announcement comes as more parcel carriers apply dimensional weight pricing to a wider range of shipments, a billing method that calculates cost based on package size rather than actual weight alone. The Boxery says its current mailer inventory, including corrugated and paperboard formats, is positioned to help sellers address this shift without redesigning their broader packaging strategy.

Dimensional weight pricing has become a routine part of parcel shipping as carriers account for the space packages occupy in delivery vehicles, not just their physical weight. Industry data from the United States Postal Service has noted that package dimensions increasingly factor into rate calculations for many commercial shipping services. As a result, sellers shipping lightweight but bulky items in traditional boxes can face charges that don't reflect the actual weight of their goods, prompting some businesses to reconsider packaging formats for items that don't require rigid protection.

Flat mailers are constructed as single-piece, scored materials that fold and, in many cases, self-lock without tape, resulting in a low-profile shape typically between one and four inches in height. The Boxery stocks these mailers in multiple sizes suited to documents, apparel, and thin promotional materials, including formats designed for books, clothing, and flat inserts. Because the mailers ship and store flat before assembly, they take up less warehouse and shelf space than pre-formed boxes of comparable capacity.

“Sellers are increasingly asking how to keep their packaging costs predictable as carriers weigh dimensions more heavily,” said the Owner of The Boxery. “Flat mailers give many businesses shipping apparel, documents, or inserts a lightweight option that still provides adequate protection for those specific product types.”
