Shenhua Xinjiang S1003 | Homopolymer PP Raffia Grade Resin for Woven Sacks & Food Contact Packaging
Product Overview
Shenhua Xinjiang S1003 is virgin homopolymer PP manufactured by Shenhua Xinjiang Coal Chemical, optimized for flat yarn extrusion. Adopting narrow molecular weight distribution formula, it delivers stable melt tension to reduce filament breakage on high-speed raffia lines.It owns balanced tensile performance and moderate resistance to dilute acid, alkali and water. The resin complies with GB 4806.6, FDA and EU 10/2011 food contact standards, passing full safety tests for food and daily woven packaging. Supported by a stable supply chain, it ensures timely delivery and competitive cost for continuous mass production.

Core Product Advantages
Balanced Rigidity & Tensile Toughness
High crystallinity PP delivers reliable structural rigidity and stable stretching performance, perfectly matching high-speed flat yarn equipment to cut broken filament defects. Woven sacks and binding ropes maintain stable dimensional stability under static load for longer service life.
Low Auxiliary Migration for Food Safety
Only thermal stabilizer is added during polymerization without extra slip or anti-block additives, greatly lowering additive bloom and migration risks. It meets strict food contact requirements and will not contaminate grain, dry food and cold food packaging.
Moderate Chemical Resistance
It withstands daily dilute water-based chemicals to extend woven packaging service life and lower replacement costs. Not resistant to strong aromatic and ester solvents, unsuitable for long-term contact with highly corrosive media.
Stable Extrusion Processability
Medium melt flow enables homogeneous plasticization for long-cycle uninterrupted production, cutting bubble and uneven gauge defects. Compatible with mainstream single-screw raffia extruders to reduce reject rates.
Main Application Fields
Food Packaging
- Food-grade woven sacks, rigid storage boxes and dry grain packaging containers, suitable for non-oily cold food packaging with full food contact compliance.
Industrial Woven Goods
- Core raw material for industrial woven sacks, binding ropes, fishing nets and civil geotextiles. Not recommended for gears, bearings, chemical storage tanks and long-term outdoor parts due to insufficient low-temperature impact and UV resistance.
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 trials are required before mass production.Drying: Ultra-low moisture absorption removes pre-drying demand under sealed storage. Dry damp pellets at 60–70°C for 1–2 hours to avoid thermal yellowing and degradation.
Storage Requirements
Storage temperature: 5–30°C; relative humidity below 60%. Do not stack bags over 5 layers to prevent deformation. Shelf life reaches 2 years under standard cool, dry and ventilated warehouse, follow FIFO management and isolate from sunlight, open fire and organic solvents.
Frequently Asked Questions
Q1: What is the warranty period?A: One-year quality warranty from delivery. Free replacement is offered for factory-caused defects under standard use; improper storage and operation are excluded from warranty coverage.
Q2: Can customized formulas be provided?A: Custom color matching via masterbatch blending is available; base resin performance cannot be adjusted without customized polymerization. Submit detailed demands to our sales team for technical evaluation.
Q3: How to guarantee product quality during transportation?A: Thickened tear-proof bags with rainproof outer film are used for full-container shipments. Reliable chemical logistics minimize moisture and collision damage, and complete COA documents are attached for incoming inspection.
Q4: What is the minimum order quantity?A: Standard MOQ is one 25-ton container; flexible small-batch supply is negotiable for long-term cooperative clients.
Q5: How to get correct processing guidance?A: Complete extrusion parameter manuals are provided per order. Our technical team offers professional parameter adjustment consultation for raffia production lines.
