PP High-Flow Impact Copolymer for Thin-wall & Food Packaging
A high-flow polypropylene impact copolymer from leading Chinese mills, EP548R combines fast-cycling fill with real impact resistance. The high MFR (~25-30) makes it ideal for thin-wall food packaging and disposable tableware, while the copolymer rubber phase delivers drop resistance that commodity homopolymers can't match. Food-contact compliant.
Thin-wall packaging demands fast fill — but fast-cycling parts still need to survive the drop. EP548R is engineered to deliver both, without the brittleness of a high-flow homopolymer.
MFR ~25-30 g/10min fills thin-wall cavities fast at lower injection pressure — enabling short cycle times and reduced wall thickness in food containers and disposables.
The impact copolymer structure preserves drop and crack resistance — thin-wall containers survive cold-fill and transport without the brittleness of a pure homopolymer.
Compliant with food-contact regulations for food packaging and disposable tableware. Low extractables and controlled composition suitable for direct food contact applications.

EP548R is built for high-cavitation, fast-cycle thin-wall molding — and for any part that needs to combine fast fill with food-contact safety and drop resistance.
Thin-wall food containers, deli tubs, and takeaway boxes — fast fill at low wall thickness without sacrificing rigidity or drop performance.
Yogurt cups, margarine tubs, and chilled food packaging requiring food-contact compliance and good sealing performance.
Cutlery, cups, plates, and lids for foodservice — high flow fills fine details; impact copolymer resists cracking in use.
Storage containers, lids, and consumer items where a balance of stiffness, impact, and surface finish is required.
Small appliance housings, internal components, and consumer electronic parts where flow and impact both matter.
Thin-wall closures and caps where high flow, dimensional precision, and tamper resistance are required.
EP548R's high flow is designed for fast-cycle thin-wall molding. Lower injection pressures and shorter cycle times are achievable versus mid-flow homopolymers.
