Pulp molded tableware is biodegradable tableware made of paper pulp through the process of forming, molding, and drying, including pulp molded cups, pulp molded bowls, pulp molded lunch boxes, pulp molded plates and pulp molded dishes, trays, etc. These products are direct food contact materials, using virgin fiber pulp as raw material, with better strength than other similar products, with high recycling value and biodegradable, and are regarded as green and environmentally friendly products.
In China, the quality requirements of pulp molded tableware follow the national standard GB/T36787-2018《Pulp Molded Tableware》. And the quality requirements of pulp molded tableware include appearance, size deviation, capacity deviation, water leakage, temperature resistance, cup stiffness, weight-bearing performance, compression resistance, lid folding test, drop test, delivery moisture, safety requirements, raw material requirements, etc.

II only for the assessment of pulp molded cups, pulp molded bowls, pulp molded lunch boxes pre-filled with hot dishes, hot food, and hot drinks. The pulp molded cups, pulp molded bowls, pulp molded lunch boxes, etc., which are claimed not to be resistant to high temperatures are not assessed, pulp molded plates, plates, trays, etc. are not assessed.
III only for the assessment of pulp molded bowls, pulp molded lunch boxes pre-filled with hot dishes and hot food. The pulp molded bowls, pulp molded lunch boxes, etc., which are claimed not to be resistant to oil are not assessed, pulp molded cups, plates, plates, trays, etc. are not assessed.
The quality requirements of pulp molded tableware —— other special requirements
Safety requirements
In the Chinese market, pulp molded tableware requirements are in line with GB 4806.8-2016 《paper and paperboard materials and products for food contact》. It stipulates that the raw materials used in paper and paperboard materials and products for food contact should not be hazardous to human health, and there are detailed regulations on physical and chemical indicators including lead and arsenic indicators, residue indicators (formaldehyde, fluorescent substances), migration indicators (potassium permanganate consumption, heavy metals), etc.
Raw material requirements
Pulp molded tableware raw materials should comply with QB/T 5051-2017 《molded paper tableware special pulp》provisions, raw materials should be non-toxic, harmless, non-polluting. Provisions for the production of molded paper tableware used in a variety of pulp including wood pulp, straw pulp, weighed pulp, bagasse pulp, bamboo pulp, or a mixture of the above.
With the rapid development of the global economy and people’s increasing awareness of environmental protection, pulp molded tableware has received more attention from all walks of life, pulp molding is a low-profit industry, every step in production should be careful. Product quality is the lifeline of pulp molded tableware manufacturers, from the design to the production stage of quality control, reducing quality problems, improving production efficiency is an important goal of enterprises.
At the same time, the quality of pulp molded tableware is also directly related to the health of end consumers. Therefore, as a biodegradable sugarcane bagasse tableware manufacturer in china, UV Tableware has been paying high attention to the quality requirements of pulp molded tableware, to ensure that all tableware flowing into the market from the company is environmentally friendly, hygienic and qualified, to protect the interests of distributors and end consumers.
