Ningmei 1102K Homopolymer PP Raffia Grade | High Tensile Extrusion Resin for Woven Sacks & Food Packaging
Product Overview
Ningmei 1102K is homopolymer PP from Ningxia Coal’s coal-to-olefin line for high-speed flat yarn extrusion. Narrow molecular distribution delivers stable melt tension and high tensile strength to cut filament breakage.
With a clean stabilizer-only formula free of slip/anti-block additives, it has low ash and minimal migration, complying with GB 4806.6, FDA and EU food standards. Every batch comes with COA for full traceability.
Large-scale production guarantees steady supply and low costs for woven sack and rope makers, while its wide processing window cuts defects and boosts line efficiency.

Core Product Advantages
Stable Tensile Performance for High-Speed Raffia
High crystallinity homopolymer PP delivers balanced rigidity and uniform stretching performance, perfectly matching high-speed flat yarn extruders to lower filament breakage. Woven sacks and binding ropes maintain stable dimensional stability under static load to extend service life.
Low Auxiliary Migration & Food Safety
No slip or anti-block masterbatch is added during polymerization, greatly reducing surface bloom and migration risks. It will not contaminate grain and dry food inside woven packaging, fully meeting strict domestic and export food packaging standards.
Moderate Chemical Resistance
It resists dilute acid, dilute alkali, water and alcohol daily chemicals to extend the service life of woven storage sacks and cut replacement costs. Not resistant to strong aromatic and ester organic solvents, unsuitable for long-term contact with highly corrosive media.
Smooth Long-Cycle Extrusion
Medium melt flow ensures homogeneous plasticization for uninterrupted mass production, minimizing bubble and uneven thickness defects. Low ash content avoids spinneret blockage, cutting mold cleaning downtime for 24-hour continuous operation.
Main Application Fields
Food Contact Woven Packaging
Food-grade woven sacks, grain storage bags and non-oily cold food rigid containers, fully compliant with global food contact regulations.
Industrial Woven Articles
Raw material for fertilizer sacks, cement woven bags, jumbo bags, binding ropes, fishing nets and civil geotextiles.Note: This homopolymer PP has weak low-temperature impact and no UV stabilizers. It cannot be used for gears, bearings, low-temperature parts and long-term outdoor structural components.
Processing & Storage Guidelines
Processing Parameters
Extrusion temperature: 190–225°C (feed zone 190–200℃, metering zone 210–225℃). Reference blending ratio of resin to color masterbatch is 95:5; small-batch trial runs are required before mass production.Drying requirement: Ultra-low moisture absorption below 0.01%, pre-drying unnecessary under sealed dry storage. Dry damp pellets at 60–70°C for 1–2 hours to prevent thermal yellowing and degradation.
Storage Requirements
Store pellets in cool, dry and ventilated warehouses, temperature 0–30°C, relative humidity below 60%. Do not stack bags over 5 layers to avoid packaging deformation. Shelf life is 2 years under standard storage; follow FIFO rules and isolate from sunlight, heat sources and organic solvents.
Frequently Asked Questions
Q1: What is the MFR of Ningmei 1102K?A: Its MFR is 3.3 g/10min under ASTM D1238 (230°C / 2.16kg), matching most mainstream high-speed flat yarn extruders.
Q2: Can this resin be used for food contact packaging?A: Yes. The clean low-migration formula meets GB 4806.6, FDA and EU standards, suitable for dry grain and cold food woven sacks.
Q3: How to store pellets to retain 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 rules.
Q4: Is it suitable for long-term outdoor use?A: Original pellets contain no UV anti-aging additives and will turn yellow and brittle under prolonged sunlight. Add UV masterbatch for outdoor applications.
Q5: Is the supply of 1102K stable?A: Relying on Ningxia large integrated coal chemical plant, we maintain full-year sufficient spot inventory and consistent batch quality to support long-term bulk orders.
