SABIC HDPE CC2056 is a narrow molecular weight distribution injection copolymer with a melt flow of 20 g/10min. It is engineered for multi-cavity cap and closure tools where fast fill, easy release and thread accuracy decide profitability.
Low warpage keeps tamper bands and threads true at high line speed, and the naturally glossy surface removes a polishing step for visible closures.

CC2056 is differentiated around the closure: high flow fills 32-72 cavity cap tools before the melt freezes off, low warpage keeps thread pitch consistent, and gloss eliminates secondary finishing for retail-visible caps.
It also runs in compression molding lines where cap makers trade injection pressure for even fiber-free parts. Either way the grade is built around the same goal: millions of caps per day with scrap below one percent.
Multi-cavity cap precision
Melt temperature 220-260 °C; keep residence short.
High injection speed for thin-wall fill without jetting.
Brief pack only; overpack slows release and adds flash.
Thin-wall cooling with matched core and cavity temps.
Water, CSD and juice closures.
Pots and carton caps for chilled lines.
Cosmetic jars and thin packaging.
Standard valve bag for palletised shipment.
FIBC for reduced handling and waste.
Bulk delivery for continuous lines.
Fill, pack and cooling for 48-cavity cap tools.
