Jwell
Jwell APET (Amorphous Polyethylene Terephthalate) and PETG (Polyethylene Terephthalate Glycol) sheet extrusion line is designed to produce high-quality plastic sheets used in various applications, such as packaging, thermoforming, and industrial uses. Here is an introduction to the main components and the process involved in Jwell production line:
1. Raw Material Handling(crystallization drying) and Feeding System:
- Hopper: Feeds raw APET or PETG pellets into the extrusion system.
- Dosing Units: Precisely measure and mix raw materials, including any additives or colorants.
2. Extruder:
- Single-Screw or Twin-Screw Extruder: Melts and homogenizes the APET or PETG material.
- Barrel and Screw: Designed for optimal mixing and melting of the material.
- Heating Elements: Maintain precise temperature control to ensure consistent material flow.
3. Screen Changer and Melt Pump:
- Screen Changer: Filters out impurities from the molten plastic.
- Melt Pump: Ensures a consistent and controlled flow of the molten plastic to the die.
4. Sheet Mould:
- T-Die: Shapes the molten plastic into a flat sheet with the desired width and thickness.
- Adjustable Lip: Allows fine-tuning of the sheet thickness.
5. Calendering Unit:
- Three-Roll Calender: Comprises a series of heated and polished rollers that shape and smooth the sheet, controlling its thickness and surface finish.
- Gap Adjustment Mechanism: Ensures precise control of sheet thickness.
6. Cooling System:
- Cooling Rollers: Gradually cool the sheet to solidify it while maintaining its dimensional stability.
- Water Cooling or Air Cooling Units: Further reduce the sheet's temperature as needed.
7. Edge Trimming and Slitting Unit:
- Edge Trimmers: Remove the edges of the sheet to ensure uniform width.
- Slitting Blades: Cut the sheet into desired widths if multiple smaller sheets are needed.
8. Haul-Off Unit:
- Pull Rollers: Draw the sheet through the extrusion line at a controlled speed, ensuring uniform thickness and preventing stretching.
9. Antistatic and Surface Treatment Units (Optional):
- Corona Treatment: Improves the surface energy of the sheet for better printability and adhesion.
10. Winding Unit:
- Roll Winder: Collects the finished sheet onto rolls for easy handling, storage, and transport.
- Tension Control: Ensures even and tight winding of the sheet.
11. Control System:
- PLC and HMI: Monitor and control various parameters of the extrusion process, such as temperature, pressure, speed, and thickness, ensuring consistent product quality.
1. Feeding and Melting: Raw APET or PETG pellets are fed into the extruder, where they are melted and homogenized by the rotating screw and heating elements.
2. Filtering and Pumping: The molten plastic is filtered to remove impurities and then pumped to the die at a consistent flow rate.
3. Sheet Formation: The molten plastic is extruded through the T-die, forming a continuous flat sheet.
4. Calendering: The hot sheet passes through a series of calender rollers, which smooth and shape it to the desired thickness and surface finish.
5. Cooling: The sheet is gradually cooled using cooling rollers and possibly additional cooling units to solidify and stabilize its dimensions.
6. Trimming and Slitting: The edges of the sheet are trimmed to ensure uniform width, and the sheet is slit into the required widths if necessary.
7. Winding: The finished sheet is wound onto rolls for storage and transportation, with tension control to ensure even winding.
8. Quality Control: Throughout the process, various parameters are monitored and controlled to ensure the sheet meets quality standards.
This production line is designed for high efficiency and precision, producing APET and PETG sheets with excellent clarity, mechanical properties, and surface quality. These sheets are widely used in packaging, thermoforming, printing, and other industrial applications.

GAG sheet is a three layers composite sheet of APET and PETG. The outstanding characteristics of the sheet are good transparency, good texture, and the cost is great reduced compared with PETG. This kind of sheet is mainly used as decorative sheet and glue coated sheet, and its application fields include building materials, furniture board, packaging, medicine and many other industries. Especially in the furniture industry, GAG sheet is gradually replacing PVC decorative sheet due to environment protection, raw material price and product characteristics, with great market prospect.
PETG is called low temperature PET, it’s a new environment-friendly packing material with features such as high luster, good transparency, excellent barrier property, self-adhesion, which is used for glue bonding and high-frequency processing.
CPET is a kind of modified PET.
With good resistance to high temperature, it is usually used for package in microwave oven.
PET stereoscopic optical grating sheet
It can be used as top grade package for cosmetics, medicine, tobacco & alcohol and common goods such as stationery, advertisements, posters and all kinds of cards.
PLA sheet
PLA is a kind of line shape Aliphatic Polyesters. PLA can be used in rigid package of fruits, vegetables, eggs, cooked food and roast food, also can be usedfor packaging of sandwich, biscuit and some other packages like fresh flower.
