Materials Used for Bankers' Boxes

Before diving deep into the bankers boxes dimensions and which one you should opt for, let’s see the different materials you can choose for the boxes. One of the most important factors is opting for the 4eco-safe packaging to reduce the carbon footprint. Keeping in mind this factor, you can choose the following three materials with respect to the size and the reason why:

Kraft for Small Boxes

Choosing Kraft packaging for smaller boxes is a wise idea because it can keep the materials safe from dust and humidity to some extent. Kraft is a durable material, but not to an extent that you can add a lot of weight inside these boxes; hence, choosing this material is preferred for small boxes. You can choose customized small bankers box dimensions as per your personal needs. 

Cardboard for Medium Boxes

Cardboard boxes are perfect for medium bankers boxes because of their durability. These boxes are better at keeping the products safe than regular Kraft. Cardboard boxes can keep the legal documents and other important files safe from factors like dust and water to an extent. You can get these boxes customized with a brand’s logo and print important information on the boxes. 

Corrugated Cardboard Large Boxes 

Before choosing the large bankers box dimensions, you should pick the material for the boxes. Corrugated cardboard is one of the strongest materials, as it offers three layers in its simplest form: the outer cardboard layers and an inner corrugated flute. You can keep your documents safe from factors such as dust, water, and even pressure inside these boxes.
