APET PETG CPET sheet extrusion line is improved from PET sheet production equipment. Depending on the type of extruder, there are different raw material processing methods. GWELL’s single-screw or twin-screw extruders can be used to produce three-layer PET sheets.

With the increasing domestic demand, packaging plastic thermoformed sheets are becoming more and more widely used, and the usage is increasing year by year, and the prospects are promising. With the country’s emphasis on environmental protection, the “environmentally friendly degradable sheet production line” adapted to production has been able to successfully supply various types of “degradable sheets” to the market.
The common production method of GWELL PET sheet machine is the rolling method, which is mainly used to produce PVC, PVDC, and other sheets; the other is the extrusion method, which is used to produce BOPS, EPS, PET, PP, HIPS and other sheets.
If you are interested in our PET sheet machines, please feel free to contact us. China Plastic Extruder Supplier- GWELL sells hundreds of PET sheet machines every year. China GWELL’s customers are all over the world. This PET sheet machine is the most common type of machine we can make. But we can also make some changes according to the customer’s requirements, such as a bigger machine model for high output, wider T-die for wider sheets, co-extruder for multi-layer sheets, etc.
PET sheet single-screw extrusion line (crystallization and drying): APETG, PETG, CPET single-screw extrusion line is one of the most advanced, mature, and stable sheet extrusion lines in China. China Plastic Extruder manufacturer – GWELL uses newer technology under the same conditions, which increases the output by 30% compared to traditional machines
PET sheet twin-crew vented extrusion line (free of crystallization and drying): PET sheet extrusion line that Gwell introduced is a twin-screw free of-crystallization and drying machine with the characteristics of lower cost and higher capacity. Gwell continued to upgrade the unit and now uses the Roots-rotary vane combination to make the vacuum degree ≤10pa, and the special alloy steel thin wall combination to improve the transparency of the product. The unique screw combination and multiple feeding devices greatly reduce the viscosity drop of PET and increase the sheet productivity and quality.
PET sheet planetary screw vented production line (free of crystallization drying): planetary multi-screw has high mixing and exhaust performance due to its structure, which increases the contact area between material and air, and can meet the needs of customers with high output and quality.
We know that a sheet machine is a machine that processes, heats, extrudes, and plasticizes plastic raw materials such as PE, PET, PVC, or starch-based raw materials. The sheets formed from these raw materials will be molded into plastic products by positive or negative pressure blister.
PET sheet machine adopts multi-extruder co-extrusion technology to produce multi-layer co-extruded composite PET sheet, which is widely used in plastic blister, printing, hardware bag, gift folding, etc.
Equipped with a precision dispenser, a uniform number of layers, adjustable layers in various proportions, and a digital display. Inclined horizontal flat structure, more convenient to operate and maintain. The roller is independently driven, and the line speed is synchronized with the extruder speed, closed-loop control, and full servo system.
The whole PET sheet machine adopts Siemens PLC control to realize automatic control of parameter setting, data operation, feedback, alarm, and other functions.
Mono extruded to make single layer pet sheet, this is a simple and normal pet sheet. Gwell will provide the specification according to the used raw material.
Co-extruded to make a Three-layer pet sheet or multi-layer pet sheet, like GAG sheet is the most commonly used PET three-layer sheet, which is composed of PETG+APET+PETG. It is widely used in furniture and decoration materials. Gwell will use double or more extruders according to the customer’s requirements.
PET (Polyethylene terephthalate) Sheet, with good transparency, high toughness, nice thermo-forming, and recycling, is widely used in the field of sealed packages.
PET sheet line, newly developed by us, firstly can be used for the production of APET, PETG, and CPET sheet, and secondly for ABA sheets (A refers to the pure resin with antis ticking agent or UV stabilizing agent; B refers to high-ratio PET recycling material) if with synchronous layer- separator (European Technology)& high –efficiency extruder.

PVC foamed board is a new model board of surface crusting with its core layer under foaming treatment which ensures a smooth surface, lightweight, and strong intensity, and it can be processed like the wood board. PVC foamed boards are widely used in fields of advertising lettering, construction, decoration, windows and doors of furniture, etc.
As China Plastic Extruder Supplier, GWELL can also extrude single-layer and multi-layer PVC boards, sheets, and large-scale PVC floor leather.
PVC foam board has the following advantages:
Foamed U-PVC product series is an environment-friendly product, which is lightweight, fire retardant, acid and alkali resistant, and highly rigidity. It has characteristics of sound insulation, anti-deformation, waterproofing, thermal insulation and etc. Due to their smooth surface, Foamed U-PVC boards are ideal and widely used for screen printing in the sign business. Because of its hard surface and good processing ability, it is also an ideal replacement for timber, aluminum, veneer, and even steel board.
