T/CI 156-2022 Single corrugated cardboard box for transport packaging and double corrugated cardboard box
Basic Information
Scope
Scope: This document specifies the classification, structural forms, technical requirements, and testing and inspection methods for single-wall and double-wall corrugated boxes used for transport packaging. This document applies to the design, production, and inspection of corrugated boxes. Other types of corrugated boxes may refer to the relevant provisions of this document. Main Technical Content: 4.2 Box Types and Designations The basic schematic diagrams of corrugated boxes are shown in Appendix A. Depending on the contents, other types of corrugated boxes may also be used. Corrugated boxes can include accessories such as dividers, pads, and bases, the types and designations of which are listed in Appendix B. The box type code of corrugated boxes consists of four digits. The first two digits indicate the box type, and the last two digits represent different box styles within the same type. 4.2.1 Slotted Type (Type 02) This type of corrugated box is typically made from a single piece of corrugated board, with the top and bottom flaps (commonly known as upper and lower lids) forming the base and lid of the box. The box can be folded flat for transport and then sealed after use. 4.2.2 Overlapping Type (Type 03) This type of corrugated box consists of several box blanks, with the base and lid separated. When in use, the base and lid are overlapped to form the box. 4.2.3 Folding Type (Type 04) This type of corrugated box is typically folded from a single piece of corrugated board to form the base, body, and lid of the box. It does not require stapling or gluing before use. 5 Technical Requirements 5.1 Materials 5.1.1 The corrugated board used for manufacturing corrugated boxes is specified in Table 1. All technical indicators shall comply with the provisions of GB/T 6544. After assembly, the strength indicators of the board tested by sampling may be 10% lower than the values specified in the document. 5.1.2 For stapled corrugated boxes,
