In today’s wave of anti-involution, pulp molding, as an important part of the environmental protection industry, is attracting more and more investors’ attention. As a complex manufacturing field, investing in pulp molding requires a comprehensive consideration of multiple key factors. This article will systematically elaborate on the six core elements that investors must pay attention…
Environmental Responsibility: Starting a Sustainable Journey from the Source The main raw materials for pulp molding products are renewable resources, such as waste paper and plant fibers (e.g., wood pulp, straw pulp, etc.). These raw materials can be continuously regenerated through waste paper recycling and the plant growth cycle, ensuring the sustainability of the raw…
Research and Development of Pulp Molding Drying Equipment (1) Direct Heating Gas Drying Line Direct heating gas (natural gas) drying line is suitable for drying paper mold products for food packaging and paper mold products for household appliance packaging with high cleanliness requirements. ① Overall Design Based on the drying process conditions and design requirements…
Pulp molded drying equipment There are many ways to dry pulp model products. In addition to direct use of sunlight to dry, according to whether the drying time is demolded, it can be divided into demolding drying and in-mold drying; according to the different heat sources used during drying, it can be divided into hot…
Drying Of Pulp Molding The raw materials for pulp molding and papermaking are pulp containing only about 1% plant fiber. After the wet paper sheet is formed, the moisture content of the wet paper sheet must be reduced to about 55% by mechanical pressing. However, the moisture content after pulp molding is as high as…
