Paper-padded mailers, essentially cushioned envelope-like bags, have gained popularity as an affordable and eco-friendly packaging solution across transportation, e-commerce, and retail sectors. 

These mailers come in 4 standard paper padded mailer sizes to cater to various product and business needs. 

The A5 size mailer (197 x 258 mm or 7.75 x 10.16 inches) is perfect for small items like DVDs, CDs, and accessories, offering enhanced protection over traditional envelopes.

The A4 size, measuring 210 x 297 mm (8.27 x 11.69 inches), is the most sought-after for its capacity to hold a diverse range of products including cosmetics, electronics, and office goods.

These bags are entirely paper-made, promoting recyclability and biodegradability, and align with efforts to reduce plastic use in fast-paced delivery and retail environments. 

Notably, Khang Thanh’s express delivery mailers are FSC-certified, ensuring the paper is sourced from well-managed forests. 

Larger items such as clothing and books fit well in the large paper padded mailer sizes (315 × 345 mm or 12.40 x 13.58 inches), while the extra-large size (348 × 368 mm or 13.70 x 14.50 inches) accommodates bulkier or multiple items efficiently, offering a space-saving alternative to cardboard boxes.
