Product Overview
PARS PET-BG821 is a high-performance bottle-grade polyethylene terephthalate (PET) resin, specifically engineered to provide exceptional clarity, strength, and durability for a variety of packaging applications. Manufactured by Shahid Tondgooian Petrochemical Co., this resin is designed to offer excellent mechanical properties such as high toughness and impact resistance, making it ideal for demanding applications such as beverage packaging, pharmaceutical containers, and food storage.

This PET grade is widely used in the production of PET bottles for both carbonated and non-carbonated beverages, as well as pharmaceutical and food packaging. The resin ensures the preservation of taste and product integrity while maintaining a strong barrier against gaseous penetration, thus extending the shelf life of packaged products.

Technical Specifications for PARS PET-BG821

Key Characteristics and Benefits of PARS PET-BG821

1. High Intrinsic Viscosity (0.82 ± 0.02 dl/g)

   • This viscosity level provides excellent mechanical strength and impact resistance, essential for producing high-quality bottles that need to endure handling and transportation.

2. Low DEG Content (≤1.5 wt%)

   • The low DEG content ensures optimal processability during molding and extrusion, minimizing the risk of degradation and defects in the final product.

3. Excellent Optical Properties (L ≥ 90, b ≤ 2.0)**

   • With superior clarity and brightness, the resin is ideal for applications requiring transparent bottles, such as beverage packaging or pharmaceutical containers, where product visibility is crucial.

4. Controlled Carboxyl End Group (≤ 32 meq/Kg)

   • This feature enhances the thermal stability of the resin, ensuring consistency in molding and extrusion processes. It also improves the durability of the final product, making it suitable for applications that demand long-term reliability, such as hot-fill applications.

5. Precise Melting Point (249 ± 3°C)

   • The resin’s melting point ensures uniform processing temperatures, reducing the risk of material degradation or inconsistent results during bottle manufacturing.

6. Low Acetaldehyde Content (≤ 1 ppm)

   • Acetaldehyde is a critical factor in food and beverage packaging, as it can affect the taste and odor of the contents. PARS PET-BG821’s low acetaldehyde levels ensure that the packaged product retains its intended flavor and freshness, making it ideal for applications like beverage packaging.

7. Minimal Water Content (≤ 0.3 wt%)

   • The low water content in the resin ensures that hydrolytic degradation is minimized during processing, leading to consistent and reliable end products.

Applications of PARS PET-BG821

1. Beverage Bottles

   • Ideal for both carbonated and non-carbonated beverages, this resin is perfect for water bottles, soft drinks, juices, and sports drinks. Its high clarity and mechanical strength ensure the packaged beverages maintain a premium appearance and durability.

2. Pharmaceutical Containers

   • PET-BG821 is well-suited for pharmaceutical packaging, where purity and clarity are crucial. Its ability to prevent gaseous exchange makes it perfect for preserving the quality of sensitive pharmaceutical products.

3. Food Packaging

   • This PET grade is highly effective for food packaging that requires both durability and high clarity, such as sauce bottles, oil containers, and other similar packaging solutions.

4. Packaging for High-Performance Products

   • The resin’s ability to provide impact resistance and gas barrier properties makes it ideal for packaging products that need superior protection, including snack foods and cosmetic products.

Processing Guidelines

1. Drying Recommendations

   • Dry the resin thoroughly before processing to ensure its low water content remains intact. Drying should be done at 170–180°C for 4–6 hours using a dehumidifier, which prevents issues related to moisture and improves product quality.

2. Molding & Extrusion Temperature

   • Melt temperature: 270–290°C
   • Ensure consistent and controlled temperature management during injection molding and blow molding processes to achieve the desired product specifications without acetaldehyde formation or material degradation.

3. Machine Throughput

   • It is crucial to optimize processing parameters, such as injection speed, screw speed, and mold cooling, to ensure uniform wall thickness and clarity in the final product.
