Overview
PARS PET-BG825 is a bottle-grade polyethylene terephthalate (PET) resin manufactured by Shahid Tondgooian Petrochemical Co. This resin is specifically designed for high-quality packaging applications that require clarity, strength, and reliability. It is commonly used in the production of beverage bottles, pharmaceutical containers, and food packaging, offering enhanced mechanical properties and superior optical characteristics.

The resin has similar properties to PARS PET-BG821, with slight variations in specific features, such as the DEG content and the maximum allowable carboxyl end group content, making it suitable for various packaging solutions, especially in applications that require high performance, durability, and visual appeal.

Technical Specifications for PARS PET-BG825

Key Characteristics of PARS PET-BG825

1. Intrinsic Viscosity (0.82 ± 0.02 dl/g)
   The intrinsic viscosity of PARS PET-BG825 is 0.82 ± 0.02 dl/g, a specification that indicates its ability to provide a balance of processability and mechanical properties. This viscosity level ensures that the resin performs effectively during molding and extrusion processes, providing a strong, impact-resistant, and highly durable finished product.

2. DEG Content (Max 2 wt%)
   The DEG content in PARS PET-BG825 is max 2 wt%, slightly higher than the PARS PET-BG821, which has a maximum of 1.5 wt%. DEG (diethylene glycol) is an impurity that can affect the thermal stability of PET resin. While the PARS PET-BG825 has a higher allowable content, it remains within the acceptable range for bottle-grade applications. The 2 wt% DEG level still ensures that the resin provides excellent clarity, mechanical strength, and processability without significant risk of degradation.

3. Optical Properties (L ≥ 90, b ≤ 2.0)**
   PARS PET-BG825 offers superior clarity and brightness with a color value of L ≥ 90* and b ≤ 2.0*, ensuring that the resin can be used for producing transparent bottles that showcase the contents well. This makes it suitable for beverages, cosmetics, and food packaging, where visual appeal plays a critical role in consumer perception.

4. Carboxyl End Group (Max 32 meq/Kg)
   The carboxyl end group content is limited to a maximum of 32 meq/Kg, a specification that ensures PARS PET-BG825 maintains thermal stability during the processing phase, as well as providing adequate hydrolysis resistance. The carboxyl end group level is vital for molding and extrusion processes and helps improve the durability of the final product, especially in high-temperature applications.

5. Melting Point (249 ± 3°C)
   PARS PET-BG825 has a melting point of 249 ± 3°C, which is consistent with PARS PET-BG821. This characteristic ensures that the resin can be processed at appropriate temperatures without degrading. It allows for consistent molding and extrusion during bottle production, ensuring that the final products retain their mechanical properties and clarity even after high-temperature processing.

6. Acetaldehyde Content (Max 1 ppm)
   The acetaldehyde content in PARS PET-BG825 is kept below 1 ppm, which is crucial for ensuring that the flavor and odor of the packaged product are not compromised. This makes PARS PET-BG825 ideal for use in food and beverage packaging, where acetaldehyde could otherwise affect the taste or freshness of the contents.

7. Water Content (Max 0.3 wt%)
   The water content is a critical factor in the processing of PET resin. PARS PET-BG825 has a maximum water content of 0.3 wt%, which ensures that there is minimal risk of hydrolytic degradation during processing. This also ensures consistent and high-quality output during bottle manufacturing, preventing issues like bubbles or visual defects in the final products.

Applications of PARS PET-BG825

PARS PET-BG825 is primarily used in applications requiring high-strength, clarity, and safe packaging. Its outstanding barrier properties and mechanical stability make it ideal for a wide range of products:

1. Beverage Bottles

   • The resin is ideal for producing bottles for carbonated and non-carbonated beverages, including soft drinks, water, juices, and sports drinks. Its optical clarity and impact resistance ensure that bottles maintain a high-quality appearance and protect the product inside.

2. Pharmaceutical Containers

   • PARS PET-BG825 is also suitable for use in the pharmaceutical industry for producing medicine bottles and syrup containers, where clarity, safety, and odor neutrality are vital to maintaining the integrity of the product.

3. Food Packaging

   • The food packaging industry benefits from PARS PET-BG825’s low acetaldehyde levels, which prevent the resin from affecting the taste or smell of the food. It is commonly used for oil bottles, sauces, and condiment packaging.

4. Cosmetic and Personal Care Packaging

   • PARS PET-BG825’s ability to produce transparent and durable containers makes it perfect for packaging cosmetics such as shampoo bottles, perfume containers, and skincare product bottles, where appearance and safety are paramount.

Processing Guidelines for PARS PET-BG825

1. Drying

   • Prior to processing, PARS PET-BG825 should be thoroughly dried to reduce moisture content. It is recommended to dry the resin at 170–180°C for 4–6 hours in a dehumidifying dryer to prevent issues during processing, such as hydrolytic degradation.

2. Injection Molding and Extrusion

   • Melt Temperature: 270–290°C
   • Molding Temperature: Keep the temperatures within optimal ranges to avoid overheating and ensure consistent results. Overheating can cause acetaldehyde formation or degrade the resin.

3. Blow Molding and Other Applications

   • During blow molding, ensure that the resin is processed under controlled temperature and pressure conditions to maintain its optical properties and mechanical strength. Proper molding speeds and cooling times must also be observed.
