Biodegradable PLA Environmental Packaging Sheet Extrusion Equipment

Production Application

What is PLA ?

Polylactic acid.It is a new bio-based and renewable biodegradable material, which is made of starch from renewable plant resources (such as corn, cassava, etc.).The starch raw material is saccharized to get glucose, and then the glucose and certain strains are fermented to produce high purity lactic acid, and then the polylactic acid with certain molecular weight is synthesized by chemical synthesis method.

It can be used in the production of PET and PLA sheets, reduce the energy consumption of pre-crystallization drying, and adapt to the production of secondary materials. It has the characteristics of high yield, low energy consumption and excellent plasticization. The screw is a building block structure with multiple combinations, and has a wide range of applications. It is not only suitable for the production of PET, but also suitable for PLA biodegradable materials and starch-based degradable materials.

PLA/PET environmental protection packaging sheet extrusion production line is mainly composed of flat double extruder, mesh changer, metering pump, die, three rollers, cooling bracket, traction, winding and so on. The new type of co-directional double-sided extruder has the characteristics of low energy consumption, simple process and easy maintenance of equipment. Its unique screw combination structure minimizes the viscosity drop of PET resin. The symmetrical thin-walled roller improves the cooling efficiency and productivity as well as the quality of sheets. The multi-component feeding device can reasonably control the proportion of new materials, recycling materials, masterbatch and so on. The sheets produced can be used in the fields of plastic absorption printing and packaging. The electric system adopts Siemens subsystem, which is characterized by simple operation, high automation and cost saving.

The extruder is equipped with a melt metering pump with a constant voltage output and a closed-loop automatic control of pressure and speed.

The whole machine adopts PLC control to realize automatic control of parameter setting, data operation, feedback and alarm functions.

New non-drying PET three-exhaust extrusion production line (no need for crystallization dehumidification drying system) is a high-quality PET and PLA sheet unit developed by the company. Its production process is simple, energy consumption is low, and production cost is greatly reduced.

PLA resin is suitable for processing on traditional pet extrusion molding machine. The thickness of the recommended sheet is within the range of 0.2-1.0mm. General mechanical requirements: ordinary screw, length-diameter ratio from 24:1 to 32 : 1, it is recommended to use a smooth bucket. After drying, the raw materials are stable in the melting state. Pla resin revode101, unlike other series of resins, is subject to the following special treatment methods:

1. Use low viscosity polystyrene or polypropylene cleaning extruder to keep the temperature in a stable state.
2. Make sure the air humidity in the feeding bucket is below dew point-40 ℃ and avoid dust pollution.
3. Under the above conditions, pla resin was poured into the extruder.
4. Adjust the temperature of the equipment to the processing temperature of pla resin.
5. When off, use a low viscosity polystyrene or polypropylene cleaning machine.

Note:
1. Before adding polylactic acid, it is important to ensure that the drying system and transportation system are clean, because if there are other materials that can not be melted at pla processing temperature, it will cause the blockage of the filter and affect the normal production.
2. If you use a polypropylene cleaning machine, you cannot use hot cross-linked polypropylene. The common feed throat cooled by extrusion sheet can be used to extrude pla sheet by single screw extruder with ratio of length to diameter from 24:1 to 36:1. It is suggested that melt pump or static mixer should be added to the die head to ensure the stable transportation of the material. At the same time, in order to ensure melt quality and improve productivity, mesh changers should also be installed.
