Materials for making the Mailer Boxes :

Some of the mailer boxes depend on the kind and size of the product, weight, fragility, shipping distance, and environmental concerns.

Some of the most-used materials for a mailer box are as follows:

  • Corrugated Cardboard: Corrugated cardboard is one of the most preferred materials; many strengths accompany this material. This material is also cheaper than other materials. Several layers of paper are bonded, with fluted layers lying between them. It provides excellent cushioning and protection.
  • Rigid Board: A rigid board, also known as a chipboard, is denser and more rigid than corrugated cardboard. This material is meant for packaging heavier or even fragile items that deserve more protection.
  • Plastic: The company offers plastic mailer boxes in the form of poly mailers. They are lightweight, rugged, and water-resistant and are best suited for shipping small items that weigh little, such as clothing or documents.
  • Kraft Paper: The Kraft paper mailer boxes are made of robust, non-chlorine bleached paper, recyclable in nature and biodegradable. This is one of the popular mailer boxes on an environmentally conscious consumer list.
  • Insulated Materials: For shipping perishable goods or items requiring a temperature-sensitive, two kinds of insulated materials are preferred: foam or bubble wrap to maintain the desired temperature for some perishable items.

The specific material for a mailer box depends on the type of product being shipped and the amount of protection required. Knowing about available materials will help you pick the best one for your shipment needs.
