2. Introduction of PETG material and boardPETG, the full English name Poly (ethylene terephthalate-1,
4-cylclohexylenedimethylene terephthalate), is a transparent,
non-crystalline copolyester. The performance of PETG is not the
same as PET.
PETG sheet has outstanding toughness and high impact strength. Its
impact strength is 3-10 times that of modified polyacrylates.
Compared with APET, it has a wide processing range, high mechanical
strength excellent flexibility, high transparency, good gloss, easy
printing and environmental protection.
While PETG sheet has the characteristics of APET sheet, its major
features are outstanding heat sealing performance, easy operation
during sealing and reliable heat sealing quality. Compared with
APET, PETG won't be crystallized even under a very high molding
temperature.For vacuum forming, even clear contours of complex
geometric shapes can be obtained. However, due to its relatively
high price, the application is subject to certain restrictions.
The chemical stability of PETG is the same as that of APET.
3. Main Features of PETG sheet/board
(1) Chemical resistance
PETG sheet can withstand a variety of chemicals and commonly used
cleaning agents.
(2) Environmental friendly
The PETG sheet substrates are all environmentally friendly
materials, which meet the requirements of food contact management.
(3) Economy
It is cheaper than PC board and more durable than acrylic.
Thermoformability PETG sheets are easy to produce products with complex shapes and
large stretch ratios. Moreover, unlike PC board and impact-modified
acrylic, this board does not need to be pre-dried before
thermoforming. Compared with PC board or acrylic, its molding cycle
is short, the temperature is low, and the yield is higher.
(4) Toughness
The extruded sheet of PETG sheet is usually 15 to 20 times tougher
than general acrylic and 5 to 10 times tougher than impact modified
acrylic. PETG sheet has sufficient bearing capacity during
processing, transportation and use, which helps prevent cracking.
(5) Weather resistance
PETG sheet provides excellent weather resistance. It can maintain
the toughness of the product and prevent yellowing. It contains
ultraviolet absorbers, which can be co-extruded into a protective
layer to protect the board from the harmful effects of ultraviolet
rays.
(6) Easy to process
PETG sheet can be sawed, die-cut, drilled, punched, sheared,
riveted, milled and cold-formed without breaking. Slight scratches
on the surface can be eliminated with a hot air gun. Solvent
bonding is also a normal operation. It is easier to process than
general acrylic, impact modified acrylic or PC board, and can be
processed for flocking, electroplating, static electricity and
other processing.

PET (Polyethylene terephthalate) extrusion line is a specialized
production line used for manufacturing PET films and sheets. PET is
a versatile thermoplastic polymer known for its excellent
combination of mechanical, thermal, and chemical properties. It is
widely used in industries such as packaging, textiles, automotive,
and electrical.
Here are some key points about the PET extrusion line:
1. High-quality extrusion: The PET extrusion line is equipped with
a high-performance extruder that ensures efficient and uniform
melting and extrusion of the PET resin. This results in excellent
film quality and consistency.
2. Precise temperature control: The extrusion line features an
advanced temperature control system that allows precise adjustment
of the heating and cooling zones. This ensures optimal processing
conditions, resulting in films with consistent properties and
thickness.
3. Multi-layer film capability: The PET extrusion line enables the
production of multi-layer films with different functionalities. By
incorporating multiple extruders and co-extrusion technology, it is
possible to produce films with enhanced barrier properties,
improved strength, or specialized surface properties.
4. Versatile film width and thickness: The PET extrusion line
offers flexibility in producing films with various widths and
thicknesses according to customer requirements. It can accommodate
a wide range of film sizes, from thin gauge films used for
packaging to thicker sheets used for industrial applications.
5. Efficient cooling and stretching system: The extrusion line
includes a precise cooling and stretching system that ensures
controlled cooling and precise stretching of the molten PET film to
achieve the desired thickness and properties. This system helps
maintain dimensional stability and control orientation.
6. Surface treatment options: The PET extrusion line can be
equipped with additional surface treatment options such as corona
treatment or plasma treatment. These treatments enhance the
adhesion of inks, coatings, or adhesives to the PET film, enabling
better printability, laminating, or bonding properties.
7. Inline quality control: The extrusion line incorporates inline
monitoring and control systems for key parameters such as film
thickness, transparency, and surface defects. This ensures
consistent film quality and allows for real-time adjustments and
troubleshooting during production.
8. Energy efficiency: The PET extrusion line is designed with
energy-efficient components and technologies to minimize energy
consumption and reduce operating costs. It utilizes advanced heat
recovery systems and optimized heating and cooling processes.
9. Automation and advanced controls: The PET extrusion line is
equipped with modern automation and control systems, including PLC
touch screens and advanced control algorithms. This facilitates
easy operation, monitoring, and adjustments for efficient
production.
10. Sustainable production: PET extrusion lines can be designed to
incorporate recycling or reclaiming systems, enabling the use of
recycled PET material and contributing to a more sustainable
production process.
The PET extrusion line offers reliable and efficient production of
high-quality PET films and sheets, meeting the diverse needs of
industries requiring PET-based materials.
