What Is a Folding Box?

A folding box, also called a folding packaging box or mailer box, is a box that locks into place and can be used right away without any separate gluing or fastening. Since it ships flat, it must be assembled before use, but the advantage is that it helps save on adhesive costs.

Types of Folding Boxes
Folding Corrugated Laminated Box: G-Type Box

A G-type box has a structure in which the three-side flap on the front is secured inside the box, so it stays closed without tape. In addition, the box sides are folded to create a double-layer structure, which provides stronger protection. Because there is no folding structure on the bottom, it also offers strong holding power.

Eco-Friendly Folding Box: Wing Box
A wing box refers to a type of box with many flaps that, despite having the basic structure of a shipping box, can keep the lid secured without tape. Because it does not require tape, it is often called a “tape-free box.” It is said that wing boxes of this kind are currently being distributed by Baedal Minjok, L’Occitane Korea, Hyundai Hmall, and NS Home Shopping.
This reflects how today’s “must-have eco-conscious consumption” has extended into “must-have eco-conscious production.” As consumers prefer environmentally friendly products, companies are responding in kind, and this trend is even showing up in box structures.
In addition, the inner box inside a sleeve box also qualifies as a folding box.

Advantages of Folding Boxes:
1. Ready to use without separate adhesive

Folding boxes do not require separate taping or adhesive. Their die-cut structure is designed so that when the box is folded, it locks firmly into place, which is why they are also called non-adhesive boxes. As a result, folding boxes are considered eco-friendly packaging. If your brand values the environment and sustainability, this kind of folding box can help maximize your brand image and the value of your products.
The importance of brand image: changes in the rising consumer generation
2. Easy storage

Because the boxes are shipped in a flat state before being assembled into a three-dimensional form, logistics costs for inventory storage, parcel shipping costs, and the risk of damage are reduced. They are easy to store in a small space, and you can assemble and ship only as many as you need, making them convenient to use and reducing the risk of unused boxes deteriorating.
