What is the material of the paper tray? Changshengtai came to tell you!

In fact, the raw material for producing paper holders is waste paper or straw pulp board. Except paper trays for food and a few high-end products (such as disposable fast food lunch boxes, etc.). ), most of the raw materials for production are waste paper. The composition of domestic waste paper recycled through different channels is very complicated, including printed waste paper mainly made of straw pulp and waste newspapers mainly made of mechanical pulp, and waste paper boxes mixed with straw pulp, which contain a certain amount of impurities (such as plastics, adhesive tapes, box nails, etc.). ) has an impact on the production process. The quality of all kinds of waste paper is very different, and the paper holders produced are also very different in performance and appearance. Different types of waste paper will also affect the forming and drying process of paper holder. According to the requirements of packaging products and the price tolerance of packaging materials, different kinds of waste paper are selected to produce paper-plastic packaging products, which is beneficial to the rational utilization of waste paper raw materials and ensures the normal production process. Changsheng Taihuanyuan, as the leader of Dongguan Paper Holding Factory, uses manual sorting to properly sort the recycled waste paper raw materials, which can also remove large impurities and reduce the difficulty of processing waste paper raw materials. Specifically, it can be divided into four categories: straw pulp-based white waste paper and natural waste paper, wood pulp-based white waste paper and natural waste paper, which are used to produce different kinds of paper holders. However, according to the actual situation, some domestic paper holder manufacturers use mixed pulp of wood pulp and straw pulp, and develop towards straw pulp. In order to achieve the use function, it is generally necessary to add functional chemical additives. If chemical additives are added, the produced products cannot be called environmental protection paper holders. At present, this production mode has been completely eliminated.
