Ningmei 1102TC Homopolymer PP | Raffia Extrusion Grade for Woven Bags & Food Packaging

Product Overview

Ningmei 1102TC is virgin homopolymer polypropylene resin manufactured on standardized gas-phase polyolefin polymerization production lines.Optimized for high-speed flat yarn extrusion, it owns narrow molecular weight distribution, stable melt flow and outstanding tensile strength to cut broken filaments during continuous raffia production.With low ash and only thermal stabilizer added, this resin meets GB 4806.6, FDA and EU food contact standards. Each batch comes with original factory COA for full quality traceability. Supported by large-scale integrated polyolefin production capacity, it delivers steady long-term supply with stable comprehensive cost level for woven sack, rope and daily plastic manufacturers. Its wide extrusion processing window minimizes parameter adjustment and molding defects to optimize continuous extrusion running stability. Relevant production trial data can be verified by batch COA and customer test records upon request.

Core Product Advantages

Stable Tensile Performance for High-Speed Raffia

High crystallinity homopolymer PP provides balanced rigidity and uniform stretching performance, perfectly matching high-speed flat yarn extruders to reduce 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 compounded during polymerization, only thermal stabilizer is added. It greatly lowers additive bloom and surface migration risks, fully complying with strict food contact requirements and avoiding contamination to grain and dry food inside woven packaging.

Moderate Chemical Resistance

It resists dilute acid, dilute alkali, water and alcohol solvents, maintaining stable performance in daily packaging scenarios and optimizing long-term usage cost under standard service conditions. Supporting material corrosion test reports are available for verification.

Smooth Extrusion Processability

Medium melt flow enables homogeneous plasticization for long-cycle uninterrupted production, reducing bubble and uneven gauge defects. Compatible with mainstream single-screw raffia extruders to reduce defective products and stabilize continuous production yield. Actual extrusion performance data can be provided with customer production trial documents.

Main Application Fields

Food Contact Woven Packaging

Food-grade woven sacks, dry grain storage bags and non-oily cold food rigid containers, applicable for food packaging with full food contact compliance.

Industrial Woven Articles

Core raw material for industrial woven sacks, binding ropes, fishing nets and civil geotextiles.Note: This homopolymer PP has low 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/antioxidant 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 molecular degradation.

Storage Requirements

Storage environment: Cool, dry and ventilated warehouse, temperature 5–30°C, relative humidity below 60%.Stacking limits: Do not stack bags over 5 layers to avoid packaging deformation and pellet compaction affecting feeding.Shelf life: 2 years under standard storage conditions, follow first-in first-out management rules. Isolate from direct sunlight, heat sources, open fire and strong organic solvents.

Frequently Asked Questions

Q1: What is the melt flow rate of Ningmei 1102TC?A: Its MFR is 3.0 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 food contact standards, suitable for dry grain and cold food woven packaging.

Q3: How to store pellets to guarantee stable performance?A: Store in cool dry warehouse within 5–30°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 stabilizers and will turn yellow and brittle after long-time sunlight exposure. Add UV masterbatch if outdoor application is needed.

Q5: Is the supply of 1102TC stable?A: Supported by large-scale standardized polypropylene integrated production lines, we maintain full-year sufficient spot inventory and consistent batch quality to support long-term bulk orders.
