PET WK-781

PET WK-781 is a medium–intrinsic viscosity Polyethylene Terephthalate (PET) resin engineered for applications requiring excellent clarity, smooth processing, and reliable mechanical performance. This grade is optimized for high-speed injection molding and extrusion, offering consistent melt flow and good dimensional stability.

WK-781 provides a balanced combination of processability, toughness, and optical quality, making it an ideal choice for lightweight packaging and general-purpose PET applications. Its controlled molecular structure ensures low degradation, stable melt behavior, and uniform 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 & Surface Gloss
  Produces transparent products with clean, attractive appearance.

• Smooth Melt Flow & Easy Processing
  Ideal for high-speed injection molding and extrusion operations.

• Balanced Mechanical Properties
  Offers good strength, stiffness, and impact resistance.

• Good Thermal Stability
  Minimizes degradation during standard PET processing conditions.

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

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

Typical Applications

• PET bottle and container preforms (lightweight)

• Small beverage and food containers

• Cosmetic and pharmaceutical packaging

• Sheet extrusion and thermoforming

• General-purpose transparent packaging

Processing Methods

• Injection Molding

• Stretch Blow Molding (SBM)

• Extrusion / Sheet Extrusion

Proper drying before processing is essential to prevent hydrolysis and to maintain optimal clarity and mechanical performance.
