3.1 The packaging of amorphous refractory materials refers to the sales packaging and transport packaging of the product. The definition is as provided in GB4122. The technical requirements for the packaging of amorphous refractory materials shall comply with the provisions of GB9174 and relevant national standards. The packaging materials should not have any physical or chemical reaction with the product to damage the product. 3.2 Products can only be packaged according to product types and brands after being inspected and meeting the standards. There are four types of packaging: bags, barrels, boxes (cases) and collective packaging, see the table below. In order to distinguish products of different types and brands, colored packaging materials can be selected in the above packaging forms. 3.3 For products that must be added with binders before use, the binders can be packaged separately. The small package of binder should be attached to the hidden position of the product packaging.

Technical requirements
According to the provisions of GB6543 and GB6544, the inner lining is plastic film or other anti-leakage materials. In order to facilitate loading, unloading, storage and transportation, the following packages (bags, boxes, barrels) are packed together to form a suitable handling unit (defined in GB4122). The box board should have no obvious burrs and holes. Its defects should not affect its structural strength. The wooden box should be vertically straight at the four corners. The thickness and width of the box board should be determined according to the weight of the loaded goods, but its thickness shall not be less than 18mm and its width shall not be less than 70mm. The box body size should be selected according to the provisions of GB4892
