Introduction to PET Polyethylene Terephthalate
As the global packaging industry develops rapidly, the performance of materials must not only meet basic requirements such as strength and transparency, but also take into account sustainability and process adaptability. PET 850H 80 plastic launched by DuPont Teijin, as a highly transparent and high-strength polyethylene terephthalate (PET) material, is not only suitable for food and industrial packaging, but also widely used in high-end electronics, pharmaceutical packaging and other fields due to its excellent processing stability. As an experienced supplier of plastic raw materials, we continue to provide polyethylene terephthalate pet plastic to help our customers stabilise production and improve product quality.
PET 850H 80 Performance Advantages
High Transparency and Optical Stability
PET 850H 80 has a high transmittance of 88.6% and a refractive index of 1.655, demonstrating excellent optical clarity, and is suitable for products with high requirements for packaging appearance, such as high-end food containers and protective packaging for electronic components.
Excellent mechanical properties and strong molding adaptability
This model of PET polyethylene terephthalate has extremely high tensile strength, up to 186 MPa in the flow direction and up to 200 MPa in the vertical direction. It also has good ductility (100% elongation in the flow direction), which effectively improves the impact resistance and deformation resistance of packaging materials.
Precise size control and low shrinkage
PET 850H 80 has a bi-directional shrinkage rate of only 1.25% in the flow direction and 0.3% in the vertical direction, which makes it more suitable for thermoforming, vacuum molding and other processing processes that require strict size requirements, effectively reducing the deformation rate and improving the efficiency of mould reuse.
Excellent barrier performance
Polyethylene terephthalate 850H 80 has a water vapour transmission rate of 27.9 g/m²/day (38°C, 90RH), which can provide better barrier protection for food, medicine and other applications that require moisture-proof preservation, and prolong the shelf life of the products.
High melting point and thermal stability
Pet 850H 80 polyethylene terephthalate has a melting temperature of 254°C, combined with a specific heat capacity of 1.17 J/(kg-°C), which means that the material can be processed and moulded at higher temperatures, and can be adapted to high-speed and high-temperature production lines to reduce the risk of mould sticking.
Environmentally Friendly and In Line with Industry Trends
PET 850H 80 plastic is a fully recyclable polyester material, which is in line with the current direction of green and low-carbon development. Low energy consumption and no odour emission during processing are conducive to the achievement of ESG targets.
In addition, due to its mechanical properties and thermal stability, the material is also gradually being used in the packaging of electronic products and medical devices, where it improves protection and guarantees cleanliness and stability at the same time.
Typical Applications of PET PET 850H 80
Food and beverage packaging (e.g. bottled water containers, food boxes, transparent trays, etc.)
Highly transparent sheet and film extrusion products
Medical packaging and cosmetic shells
Insulation film materials for electronic products
Basic materials for industrial products with high performance requirements
