Shandong Tongjia Machinery is coming with PLA degradable foaming tableware equipment

Shandong Tongjia Machinery Co., Ltd. is a modern technology enterprise integrating science, industry and trade. The company has a national plastic machinery research and development center and a national physical foaming research institute. Professional R&D and production of a series of foam production lines/fast food box production lines, extruded insulation board production lines, foam sheet film production lines, foam net/tube/rod production lines, foam sheet production lines, micro-foaming production lines, etc.
First, it will be dried, then other additives will be added and mixed evenly, put into the hopper of the extruder, after extrusion, melting and plasticization, physical foaming agent will be injected, and the low temperature will be formed through the mixing and cooling of the secondary extruder. The homogeneous melt is extruded through a specially designed controllable foaming die, sizing and cooling by a sizing device with internal and external circulation cooling, and then split, flattened, rolled up, inspected and packed into storage.
Polylactic acid is a new type of biodegradable material made from renewable plant resources such as starch derived from corn. The starch raw material is saccharified to obtain glucose, which is then fermented with glucose and a certain strain of bacteria to produce high-purity lactic acid, and then polylactic acid with a certain molecular weight is synthesized through chemical synthesis. It has good biodegradability and can be completely degraded by microorganisms in nature after use, eventually generating carbon dioxide and water without polluting the environment. This is very beneficial to protecting the environment and is a recognized environmentally friendly material. It is your responsibility to care for the earth. According to news reports, the world's carbon dioxide emissions will rise to 100 degrees Celsius in 2018. Ordinary plastics are still disposed of by incineration, causing a large amount of greenhouse gases to be released into the air, while polylactic acid plastics are buried in the soil and degrade. Carbon dioxide directly enters soil organic matter or is absorbed by plants. It is not emitted into the air and does not cause a greenhouse effect.
