5m2 multilayer, waterproof

6.1.4.18.1 the bag must be made of suitable kraft paper or paper with the same performance, with at least three layers, and the middle layer can be a shaped cloth pasted on the outer layer with adhesive. The strength of the paper and the structure of the bag must be compatible with the capacity and purpose of the bag. Joints and closures must be leak proof

6.1.4.18.2 bag 5m2: in order to prevent moisture from entering, paper bags with four or more layers must be made waterproof by the following methods: one of the outermost two layers is used as a waterproof layer, or a waterproof layer made of appropriate protective materials is sandwiched between the outermost two layers. For waterproof three-layer paper bags, the outermost layer must be waterproof. When the contents may react with moisture or are packaged under wet conditions, the layer in contact with the contents must be a waterproof layer or waterproof layer, such as double-sided tarpaulin kraft paper, plastic coated kraft paper, plastic film pasted on the inner surface of the bag, or one or more layers of plastic inner lining. Joints and closures must be waterproof
