PET WK-821

PET WK-821 is a premium Polyethylene Terephthalate (PET) resin engineered for applications that require excellent clarity, enhanced mechanical strength, and stable thermal performance. This grade is designed for injection molding and extrusion processes where higher intrinsic viscosity, strong melt strength, and consistent processing behavior are essential.

WK-821 delivers improved rigidity, toughness, and melt stability, making it suitable for demanding packaging and thermoforming applications. Its optimized molecular structure ensures smooth melt flow, reduced degradation, and high-quality finished products.

Our Quality Assurance and Shipping Process

Material Guarantee We assure you that the material will meet the specifications of the loading pictures and the sample provided prior to shipment. Customer satisfaction and transparency are our top priorities.

Our Step-by-Step Process

1. Quality Inspection:
• Before finalizing the shipment, our Quality Control (QC) team conducts a thorough inspection of the material to ensure it meets the agreed-upon standards.
• Detailed videos and pictures of the material are captured during the inspection and shared with the customer for approval.
2. Container Booking:
• Once the customer approves the material, a container is booked on the next available vessel to ensure prompt delivery.
• The booking details, including the shipping schedule, are shared with the customer for tracking purposes.
3. Loading and Documentation:
   • Material condition
   • Loading procedure
   • Container and seal numbers
• The material is carefully loaded into the container.
• During loading, we document the entire process with pictures and videos, capturing essential details such as:
• These visuals, along with the draft of the Bill of Lading (BL), are shared with the customer for verification.
4. BL Draft Confirmation:
• The customer reviews and confirms the BL draft.
• Based on the confirmation, the Original Bill of Lading (OBL) is issued.
• A copy of the OBL is then shared with the customer.

Key Features & Benefits

• Excellent Optical Clarity & High Gloss
  Produces transparent products with premium visual appearance.

• Enhanced Mechanical Strength & Stiffness
  Provides excellent tensile strength, rigidity, and durability.

• Higher Melt Strength
  Supports uniform wall thickness and improved thermoforming performance.

• Good Thermal Stability
  Performs reliably during high-speed PET processing.

• Low Acetaldehyde Formation
  Suitable for food-contact and beverage packaging applications.

• Excellent Chemical Resistance
  Resistant to oils, greases, and many common chemicals.

Typical Applications

• PET bottle and container preforms

• Food and beverage packaging

• Cosmetic and pharmaceutical containers

• Sheet extrusion and thermoforming

• High-strength transparent packaging products

Processing Methods

• Injection Molding

• Extrusion / Sheet Extrusion

Thorough pre-drying before processing is mandatory to prevent hydrolysis and to achieve optimal mechanical and optical properties.
