Jwell PET Single screw/ Double screws extrusion line (PP/PS/PC/PMMA/PE Sheet）

Product Details

PET/PLA environmentally friendly sheet extrusion production line: Jwell has developed a PET/PLA sheet parallel twin-screw extrusion production line, which is equipped with a degassing system and does not require drying and crystallization devices.

The PET/PLA environmentally friendly sheet extrusion production line can be used in the production of PET and PLA sheets, reducing energy consumption in pre-crystallization and drying, and is suitable for the production of secondary materials.

The PET/PLA environmentally friendly sheet extrusion production line is not only suitable for PET production, but also for PLA biodegradable materials and starch-based degradable materials.

The PET/PLA environmentally friendly sheet extrusion production line mainly consists of a flat-twin extruder, a screen changer, a metering pump, a mold, three rollers, a cooling bracket, traction, and winding.

The extruder adopts a new type of co-directional flat twin, which has the characteristics of low energy consumption, simple process, and easy use and maintenance of the equipment.

The unique screw combination structure minimizes the viscosity drop of PET resin.

Symmetrical thin-walled rollers improve cooling efficiency while improving productivity and sheet quality.

The multi-component feeding device can reasonably control the proportion of new materials, recycled materials, masterbatch, etc., and the sheets produced can be used in blister printing, packaging and other fields.

The electrical system adopts Siemens system, which is easy to operate, has a high degree of automation and saves costs.

The barrel is equipped with double vacuum exhaust devices to ensure that water vapor is fully discharged.

The extruder is equipped with a melt metering pump, with quantitative and stable output, and closed-loop automatic control of set pressure and speed.

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

The new drying-free PET three-exhaust extrusion production line (no need for crystallization, dehumidification, and drying systems) is a high-quality PET and PLA sheet unit independently developed by Jwell. The production process is simple, the energy consumption is low, and the production cost is greatly reduced.

Introduction to the People's Liberation Army

Polylactic acid (PLA) is a new bio-based renewable biodegradable material made from starch raw materials derived from renewable plant resources (such as corn, cassava, etc.).

The starch raw material is saccharified to obtain glucose, which is then fermented with certain strains to produce high-purity lactic acid, and then polylactic acid with a certain molecular weight is synthesized through chemical synthesis.

PLA has good biodegradability. After use, it can be completely degraded by microorganisms in nature under specific conditions, eventually producing carbon dioxide and water without polluting the environment. This is very beneficial to environmental protection and is recognized as an environmentally friendly material.

PET/PLA uses

• Product use: excellent processing performance, transparency, barrier properties, non-toxic, odorless, pollution-free, and easy to recycle.
• Vacuum forming: food packaging, toy boxes, stationery boxes, gift boxes, hand tools, hardware packaging.
• Barrier use: electronic parts packaging.
• Universal: folding molding, garment collars, decorative materials, folders, document covers.
• Special uses: medical equipment, pharmaceutical packaging, industrial anti-corrosion protection, microwave oven baking sheets.

PET/PLA environmentally friendly sheet extrusion production line performance and advantages

PET/PLA environmentally friendly sheet extrusion production line: The PET/PLA sheet parallel twin-screw extrusion production line developed by Jwell is equipped with a degassing system and does not require drying and crystallization devices. The extrusion production line has the characteristics of low energy consumption, simple production process and easy maintenance. The segmented screw structure can reduce the viscosity loss of PET/PLA resin, and the symmetrical thin-walled calender roller enhances the cooling effect, improving production capacity and sheet quality. The multi-component dosing feeder can accurately control the proportion of new materials, recycled materials and color masterbatch, and is widely used in the thermoforming packaging industry.
