Ningmei FC5608 Homopolymer PP Raffia Grade | Anti-Blocking Extrusion Resin for Woven Bags & Industrial Packaging
Product Overview
Ningmei FC5608 is premium homopolymer polypropylene resin produced by Ningxia Coal Industry coal-to-olefin plant, customized for flat yarn extrusion and woven fabric production. Advanced gas-phase polymerization technology delivers narrow molecular weight distribution, stable melt tension and inherent anti-coking extrusion performance to avoid die buildup during long continuous raffia production.It features balanced tensile strength and low additive migration, fully compliant with GB 4806.6, FDA and EU food contact standards for dry grain woven packaging. Consistent batch quality is guaranteed with complete COA test reports for every shipment. Abundant coal-to-olefin production capacity ensures stable long-term supply and competitive raw material cost for woven manufacturers.The resin maintains stable melt fluidity within a wide processing window, cutting frequent equipment parameter adjustment and lowering filament breakage defects in high-speed extrusion lines. Only thermal stabilizer is added in the base formula to reduce surface bloom and meet high cleanliness packaging demands.

Core Product Advantages
High Stable Extrusion Efficiency
Controlled medium melt flow enables homogeneous plasticization for uninterrupted high-speed flat yarn production. Stable melt tension drastically reduces broken filaments and uneven yarn thickness, lifting overall line output and lowering reject rates.
Low Pollution & Food Contact Cleanliness
The simple thermal-stabilizer-only formula avoids extra slip and anti-block additive precipitation. No surface bloom will contaminate food goods inside woven sacks, satisfying strict domestic and export food packaging safety regulations.
Excellent Anti-Deposition Extrusion Performance
It effectively prevents carbon buildup and coking inside extruder dies after long-time continuous running, cutting regular die cleaning downtime and extending service life of extrusion equipment.
Sustainable Stable Supply
Supported by large-scale coal-to-olefin integrated production base in Ningxia, batch performance stays consistent all year round, eliminating raw material shortage risks for mass woven product manufacturers.
Main Application Fields
Food Contact Woven Packaging
Food-grade woven sacks for grain, powder and dry cold goods; rigid plastic packaging containers for non-oily food storage.
Industrial Woven Articles
Flat yarn for industrial woven sacks, binding ropes, fishing nets and civil geotextiles. Not suitable for low-temperature impact parts, long-term outdoor structural components and chemical solvent storage vessels due to lack of UV stabilizer and low low-temperature toughness.
Processing & Storage Guidelines
Processing Parameters
Extrusion temperature:190–225°C (feed zone 190–200°C, metering zone 210–225°C). Reference blending ratio of resin to color masterbatch is 95:5; small-batch trial test is required before mass production.
Drying Requirements: Pre-drying is unnecessary under sealed dry storage. Dry damp pellets at 60–70°C for 1–2 hours to avoid thermal yellowing and degradation.
Storage Requirements
Storage environment: Cool, dry and ventilated warehouse, temperature 0–30°C, relative humidity below 60%.Stacking Limits: Do not stack bags over 5 layers to prevent packaging deformation and pellet compaction.
Shelf Life: 2 years under standard storage conditions. Follow first-in first-out rules, keep away from direct sunlight, heat sources and open fire.
Frequently Asked Questions
Q1: What is the melt flow rate of Ningmei FC5608?A: Its MFR is 3.2 g/10min under 230°C/2.16kg ASTM D1238 test standard, matching most mainstream high-speed flat yarn extruders.
Q2: Does this resin meet food contact standards?A: Yes. It adopts low-migration clean formula and complies with China GB 4806.6, US FDA and EU 10/2011 standards, applicable for dry food woven packaging.
Q3: How to store the pellets to keep stable performance?A: Store in cool dry warehouse within 0–30°C with humidity below 60%, stacking height limited within 5 layers, and use up within 2 years following FIFO management.
Q4: Can it be matched with all raffia extrusion equipment?A: It fits most single-screw flat yarn extruders. Minor temperature adjustment is suggested when switching raw materials for new production lines.
Q5: Is the supply of FC5608 stable?A: Relying on Ningxia large coal-to-olefin integrated plant, we maintain full year round inventory and stable batch supply to support long-term bulk orders.
