Several materials are commonly used for manufacturing mailer boxes. Here are some of the most commonly used materials:

1. Corrugated Cardboard: Corrugated cardboard is a popular choice for mailer boxes. It consists of three layers: two flat outer layers and a wavy inner layer (corrugated medium). This construction provides strength, durability, and cushioning properties, making it suitable for shipping and protecting various products.

2. Kraft Paper: Kraft paper is a sturdy and eco-friendly material made from wood pulp. It is often used for manufacturing mailer boxes due to its strength and natural brown appearance. Kraft paper is recyclable and provides good protection for lightweight to moderately heavy items.

3. Cardstock: Cardstock, also known as paperboard or chipboard, is a thick and rigid paper material. It offers good printing properties, allowing for high-quality graphics and branding. Cardstock is commonly used for retail packaging and smaller-sized mailer boxes.

4. Solid Fiberboard: Solid fiberboard, also referred to as chipboard or particleboard, is made from compressed paper fibers. It provides moderate strength and protection, making it suitable for lightweight products or as inner packaging components within mailer boxes.

5. Plastic: In some cases, plastic materials such as polypropylene (PP) or polyethylene (PE) may be used for mailer boxes. These materials offer moisture resistance and can be suitable for specific product requirements or when shipping conditions demand extra protection.

It's worth noting that the choice of material depends on factors such as the nature of the product, shipping requirements, budget, and sustainability considerations. Manufacturers often offer different material options to cater to various customer needs.
