Corrugated Mailers: Shipping, Packaging, Corrugated Cardboard Products And Manufacturers

Published: May 18, 2007

Shipping and packaging are everyday activities for many people around the world. From mailing packages to friends and relatives on holidays to sending professional materials, it's likely that anything large enough to require a box is being packaged in corrugated mailers. In fact, more than ninety-five percent of all items shipped in the United States are shipped in corrugated cardboard.

Corrugated mailers are among the most durable form of cardboard shipping materials. There are a number of benefits to using corrugated mailers for shipping and packaging. Corrugated products provide protection for any material shipped in them. Manufacturers achieve this by introducing a wavy layer of paper or "fluting" between two layers of flat board. The flutes are initially as flat as the outer lining, but they are steamed and heated, then pressed against the first layer of flat paper and held in place with adhesive. Then the second layer of liner is placed along the other side. The air between the layers of flat board give insulation against piercing or battering, while the flutes maintain structural integrity. Standard corrugated cardboard comes in single or double width, though large or heavy objects can even be shipped in triple layers. Corrugated mailers are lightweight, flexible, and extremely cost-effective.

Corrugated cardboard is also amongst the most commonly recycled material. Since they are durable, corrugated mailers can often be reused for packaging. It is also easily reconstituted, and corrugated cardboard accounts for more than half of all recycled paper materials in the United States each year, with more than three quarters of all corrugated materials being recovered for recycling. Additionally, most corrugated mailers are made (at least in part) from already recycled materials, making it one of the most environmentally responsible products available.

According to the Corrugated Packaging Association, the first corrugated materials were developed for insulation in tall Victorian hats in 1856. However, it wasn't until 1903 that corrugated cardboard was approved for use as shipping material, used initially just for cereal.

Shipping and packaging needs are becoming increasingly more specific, and the solution can be found in corrugated mailers. Corrugated mailers are specifically designed for shipping and come in a variety of sizes and shapes, including standard box, side loading, and even triangular tubes, but all are manufactured with the intent of being easy to assemble without the aid of glue or tape. Corrugated mailers are typically made with 200lb. test bursting resistance and size B flute (1/8 inch thick) corrugated paper, with a high durability against edge crushing. Corrugated mailers are often shipped from manufactures in bundles, often available in multiples of fifty, and can be custom printed or left blank.

Corrugated mailers provide an easy and effective solution for packaging and shipping. The flat material is pre-pressed or perforated to make folding easy. While some corrugated mailers have adhesive tape attached, many simply are created with flaps that fold shut, sealing the contents securely within the package. With minimal assembly, any shipper can provide his or her recipient with their materials in an attractive receptacle that is resistant to damages during shipment.
