This eco-friendly mailer is made from a unique three-layer material design: the innermost layer is honeycomb paper for cushioning protection, while the outer two layers are durable kraft paper. The innovative honeycomb structure absorbs shocks and prevents damage during shipping, eliminating the need for plastic bubble wrap. As the entire material is recyclable and biodegradable, this mailer is a sustainable alternative for e-commerce, retail, and logistics businesses. Strong, protective, and environmentally responsible, it ensures safe delivery while reducing environmental impact.
