1. For general dry goods, it is recommended to use national waste or European waste, and control the production of base paper according to the technical indicators of A or B grade kraft cardboard. The surface layer can be noodles or not, depending on whether complex patterns and advertisements are printed. The basis weight of the paper can be 135~150 g/m2. The 25*20*15cm paper bag can bear a weight of 8~15 kg.
2. For goods that need to withstand a certain amount of moisture, whole waste paper can also be used. Only on the basis of the above standards, add a certain amount of wet strength agent 0.5~1.0%, the wet strength can reach 10~15% of the dry strength.
3. For meat or other wet goods, shopping bags can also be made of waste paper. This requires adding an environmentally friendly oil repellent to the pulp or coating the surface during the papermaking process. It is also possible to spray water-soluble or degradable resin on kraft cardboard paper with good surface strength.
4. When making paper, water-soluble yarn is added between the two layers of slurry in combination with the spinning principle. This kind of paper can reach the strength of four-layer kraft paper and can completely replace ordinary cement bag paper. Similarly, single-layer paper can be used on shopping bags.
5. These products are safe and environmentally friendly.
