The global mailer packaging market size is anticipated to reach USD 108.99 billion by 2033, registering a CAGR of 14.9% from 2026 to 2033, according to a new report by Grand View Research, Inc. Growing adoption of flexible packaging over traditional corrugated boxes in e-commerce, shipping & logistics, and manufacturing industries is expected to contribute to the market growth.

Growing sustainability initiatives across the globe are driving the adoption of paper mailers over plastic mailers among end users. For instance, in October 2023, Amazon.com, Inc. announced that its first automated fulfillment center in the U.S. was upgraded by retrofitting existing machines to use paper for packaging instead of plastic.

The trend of buying clothes, electronics, consumer goods, and other accessories online is growing with the increasing influence of social media platforms.

Incorporation of Quick Response (QR) codes and Radio Frequency Identification (RFID) technologies in poly mailers adds value by offering authentication of products, their information, and tracking of delivery. In addition, the adoption of adhesive closures and tamper-evident seals to enhance the security of poly mailers is expected to drive the demand for poly mailers in the coming years.

In December 2023, Kite Packaging launched Enviro Mailers. These mailers have a unique design that includes three layers of paper and a single layer of slit-expanded honeycomb paper to provide optimal cushioning protection for goods in transit.
