About Hdpe Blow Grade Granules
HDPE Blow Grade Granules are pellets of
High-Density Polyethylene (HDPE) formulated specifically for
blow molding a plastic forming process that creates hollow parts by inflating a molten polymer into a mold. They typically come in pellet form (25 mm size) and can be virgin, recycled, or additive-enhanced.
ey Physical & Chemical Properties
-
Density: 0.9450.965 g/cm higher than many other polyethylenes, giving stiffness and strength.
-
Melt Flow Index (MFI): 0.041.0 g/10 min (varies by grade) lower MFI means higher molecular weight, suitable for thick-walled and strong blow molded parts.
-
Melting Range: 210290 C typical processing window for blow molding.
-
Chemical Resistance: Good to acids, alkalis, solvents and most chemicals; low water absorption.

Versatile Extrusion Blow Molding ApplicationsSpecifically formulated for extrusion blow molding, our HDPE granules deliver consistent results for manufacturing bottles, containers, and a wide variety of industrial packaging. Their smooth, glossy surface finish ensures enhanced product appeal and reliable performance in demanding applications.
Premium Quality and Food-Grade SafetyManufactured to meet stringent industrial and food-grade standards, these HDPE granules exhibit minimal contaminants and exceptionally low moisture levels (<0.1%). Their high tensile strength and elongation at break contribute to robust, durable packaging that is safe for direct food contact.
Optimized for Easy Handling and Long Shelf LifePackaged in robust 25 kg or 50 kg bags, our HDPE granules are easy to transport and store. For extended shelf life and optimal performance, keep them in cool, dry conditions away from direct sunlight. Custom weight options and thicknesses are available upon request.
FAQ's of Hdpe Blow Grade Granules:
Q: How are HDPE Blow Grade Granules used in extrusion blow molding?
A: HDPE Blow Grade Granules are melted and formed into parisons through extrusion blow molding machines. These parisons are then inflated within a mold to create hollow shapes like bottles and containers, which are commonly used in food and industrial packaging.
Q: What advantages do these HDPE granules offer for food-grade packaging?
A: These HDPE granules possess low contaminant levels, minimal moisture content (<0.1%), and meet food-grade standards. This ensures safety, durability, and compliance for packaging that comes into direct contact with food items.
Q: When should I choose HDPE granules with a Melt Flow Index of 0.3-1.0 g/10min?
A: Granules within this MFI range are ideal for extrusion blow molding processes where controlled flow and forming are critical. They ensure uniformity in wall thickness and stable processing characteristics for high-quality end products.
Q: Where can these HDPE granules be used?
A: These granules are versatile and suitable for manufacturing bottles, containers, and other blow-molded products used in food packaging, industrial storage, and transportation across facilities worldwide.
Q: What storage conditions are recommended for maintaining the quality of these granules?
A: For best results, store the granules in a cool, dry environment away from direct sunlight. Proper storage reduces moisture absorption and maintains consistent processing characteristics.
Q: How does the surface finish benefit the final product?
A: The smooth and glossy surface finish provided by these HDPE granules enhances the visual appeal and hygiene of the final products, which is especially important for food-grade and consumer-facing items.
