Main Technical Content: 3. Packaging Material Requirements 3.1 Requirements for Packaging Boxes, Pallets, and Other Packaging Materials 3.1.1 Packaging materials primarily include cardboard boxes, wooden boxes, plastic strapping, steel strapping, plastic films, and metal sheeting, among others. All packaging materials must comply with national environmental laws and regulations, relevant national standards, and industry standards, and be recyclable, reusable, or biodegradable. 3.1.2 Cardboard boxes should be heavy-duty corrugated boxes or double-layer corrugated boxes. The schematic diagram of the cardboard packaging structure is shown in Figure 1. 3.1.3 For domestic packaging wooden boxes, the moisture content of the wood used should be ≤18%. For export packaging wooden boxes (without fumigation), the moisture content should be ≤12%. The wood must also undergo chemical fumigation, high-temperature heat treatment, or other processing, and no residual bark is allowed on the wood. The schematic diagram of the wooden box structure is shown in Figure 2. 3.1.4 The dimensions of packaging boxes should meet the product requirements. It is permissible to add filling materials inside the box (provided they do not adversely affect the product), ensuring that the product does not shift or get crushed within the box. When using containers for shipping, the main dimensions and tolerances of the pallets used must comply with GB/T 2934 or the user's requirements. 3.1.5 Pallets can be made of wood, metal, or other materials. They must ensure sufficient strength and not cause damage to the products due to breakage. The dimensions of the pallets should meet the product requirements. 3.1.6 When making wooden boxes and pallets, the nails should be arranged in a staggered pattern with the heads flush and the points facing downward. No protruding or missing nails are allowed. Protection brackets should be installed at the lifting positions. 3.1.7 For metal pallets, they
