It is about.

Pallet is a packaging material used as a stand in the process of transporting products made by the company's production activities, and the domestic pallet industry is showing steady growth. Specifically, the pallets that were used to transport US military supplies during the Korean War of the Korean War began to be active in the beverage and beer industries in the 1980s, and from the 1990s, 3D industry avoidance and industrial production As the quantity of goods rapidly increased, the demand for pallets increased further as the unloading and loading of products became mechanized, and the domestic market is currently reaching 400 billion won, thanks to the high growth rate of 16-20%.

The domestic market of these pallets is surveyed by wood, plastic, steel, and others. Until 1990, only pallets were produced, plastics began to be produced in the 1990s, and steel pallets appeared in the 2000s. . On the other hand, wood currently produced is still leading the market share of 71.1%, plastic is the market share of 25.3%, steel is the most late commodity steel 3.1% and other (resin, styrofoam, special materials) Occupies 0.5%.

Among these pallets by material, wood is still leading the production, but its market share is gradually being lowered due to its large weight, volume, and troublesome handling, especially quarantine, which threatens its position in the market. . The most prominent phenomenon in the current pallet industry is the noticeable increase in the growth rate of plastic pallets, which is stronger than wood, durable, permanent, reusable, not inspected by customs, and not absorbing moisture. Because there is an advantage.

However, the plastic products that are growing in this growth rate and share are generally used as shown in Figure 1 or 2, but also has a big disadvantage, such as high price and weight.

Accordingly, metal pallets have recently been produced as replacements for wooden pallets and plastic pallets. The advantages of these metal pallets are that they are strong and eco-friendly, easy to fabricate, and lighter than plastics, and are less expensive than plastic pallets. Due to these advantages, metal pallets are on the rise.

However, most metal pallets are more expensive than wooden pallets, and in order to produce more competitive products, the production know-how can be made lighter at a lower cost while maintaining strength.

On the other hand, pallets, along with the development of logistics, required consistent palletization consisting of loading, transporting, unloading, and storage without any transfer between production and final consumer.

As a result, in December 1995, the “Unit Rod System Rule” was enacted, and T-11 type (1100 × 1100mm) was selected as the national standard pallet and logistics efficiency was promoted. In 2003, “Logistics standard equipment certification system” In 2007, the Logistics Management System Certification System, an upgraded version of the logistics standard certification system, was implemented. In addition, in 2009, Pallet standard pluralization was added to the existing T-11 type T-12 (1000 × 1200mm) as a standard standard. In addition, Pallet Standardization has been promoted.
