Engineered for high-speed line drawing, anti-fibrillation, and superior pigment dispersion across polyolefin applications.
Analyzing the macro-economic shifts, polymer processing parameters, and colorant engineering requirements in modern polyolefin raffia manufacturing.
The global flexible packaging market has witnessed a massive transformation driven by the escalating demand for high-strength Polypropylene (PP) and Polyethylene (PE) woven sacks, Flexible Intermediate Bulk Containers (FIBCs), agricultural shade nets, and geotextiles. As a leading China Woven Bag Drawing PE Masterbatch Company & Supplier, Changzhou Jiazhou Plastic Products Co., Ltd. delivers engineered additive and colorant formulations designed specifically for continuous tape extrusion (drawing) lines operating at speeds exceeding 450 to 550 meters per minute.
In high-speed tape drawing (raffia extrusion), standard masterbatches often fail due to thermal degradation, pigment agglomeration, filter clogging, and tape breakage (fibrillation). A specialized PE drawing masterbatch must possess precise melt flow index (MFI) matching, micro-sized pigment dispersion (Filter Pressure Value FPV < 0.8 bar/g), and superior heat stability to withstand temperatures between 240°C and 280°C without shade shifting or thermal gasification.
Utilizing virgin Linear Low-Density Polyethylene (LLDPE) and High-Density Polyethylene (HDPE) carrier systems ensures perfect melt blending with PP/PE matrix polymers, preventing delamination and split-tape defects during draw orientation.
Micro-milled pigment particles are double-pass extruded through co-rotating twin-screw extruders, guaranteeing zero screen-pack clogging and maximum tensile strength retention during the 1:5–1:7 stretching process.
Formulated with Hindered Amine Light Stabilizers (HALS) and Rutile TiO2 or furnace carbon black to protect agricultural woven sacks and FIBC bulk bags against severe outdoor photodegradation in tropical zones.
In-depth comparative analysis of physical parameters required for seamless tapeline extrusion and woven sack production.
During the tapeline drawing process, plastic melt is extruded into a flat film, water-quenched, slit into narrow tapes, and then heated and stretched longitudinally over godet rollers. The introduction of poor-quality color masterbatch causes micro-voids, necking, and high water-carryover. The engineering metrics below highlight the rigorous standard maintained by Changzhou Jiazhou Plastic Products Co., Ltd.
| Property Parameter | Standard PE Masterbatch | Jiazhou Drawing PE Masterbatch | Impact on Woven Bag Production |
|---|---|---|---|
| Carrier Resin Base | Recycled / Mixed PE | 100% Virgin LLDPE / HDPE (MI: 4-12g/10min) | Prevents tape snapping; eliminates structural weak points. |
| Filter Pressure Value (FPV) | > 2.5 bar/g | ≤ 0.6 – 0.8 bar/g (EN 13900-5) | Extends filter screen pack lifespan by up to 300%. |
| Thermal Stability | 200°C – 220°C | 260°C – 280°C Continuous | No color shifting, gas bubbles, or odor at high extrusion temperatures. |
| Moisture Content | < 0.15% | ≤ 0.05% (Vacuum Dehydrated) | Eliminates water-carryover onto drawing rollers; reduces strip breaks. |
| Pigment Loading Concentration | 20% – 35% | 40% – 70% High Concentration | Lower let-down ratio (LDR 1%–3%); significantly reduces unit production cost. |
| Light Fastness (Blue Wool Scale) | Grade 4–5 | Grade 7–8 (High Weatherability) | Prevents fading in outdoor fertilizer bags and FIBC containers. |
Tailored masterbatch systems engineered for demanding industrial, agricultural, and commercial polyolefin applications.
Bulk transport bags require extreme load-bearing capability (SWL up to 2000kg). Our high-concentration masterbatches integrate functional processing aids that preserve tape tensile strength and elongation while providing uniform opacity.
Used in shade nets, greenhouse covers, and crop storage woven sheets exposed to intense solar radiation. Features synergistic UV stabilization packages (HALS + UV Absorbers) tested to pass 3000+ hours of QUV accelerated weathering.
High anti-migration properties prevent color bleeding when in contact with acidic or alkaline chemical fertilizers. Compliant with international food-contact and industrial safety standards (RoHS, REACH).
Pioneering eco-friendly compounding, circular polymer integration, and smart masterbatch solutions.
In response to global plastic waste regulations, Jiazhou is launching 100% Post-Consumer Recycled (PCR) carrier masterbatches modified with melt-compatibilizers to restore tensile parameters in recycled woven sacks.
Integrating nano-graphene dispersion into PE masterbatches to increase orientation tape tensile strength by up to 25%, allowing woven sack manufacturers to down-gauge film thickness without sacrificing burst pressure.
Next-generation hydrophobic surface modifiers eliminate moisture hold-up during water-bath cooling in tapelines, enabling ultra-fast drawing speeds without line slippage.

Expert answers on tapeline processing, masterbatch selection, let-down ratios, and defect prevention.
For high-concentration PE masterbatches supplied by Jiazhou, the standard Let-Down Ratio ranges between 1% to 3% by weight, depending on the required opacity, color intensity, and tape thickness. Due to high pigment loading (up to 70%), using 1.5% to 2% is typically sufficient for standard PP/PE woven sacks, yielding significant cost savings.
Tape breakage occurs primarily when pigment agglomerates or incompatible carrier resins create micro-voids during longitudinal stretching (1:5 draw ratio). Jiazhou drawing masterbatches utilize virgin LLDPE carrier resins and undergo fine filtration (≤ 0.6 bar/g FPV), guaranteeing smooth molecular orientation without film tearing.
Yes. Low-density PE acts as a toughening agent and processing aid in PP raffia tape production. When formulated with high MFI PE carriers, it enhances tape flexibility, reduces needle splitting during bag sewing, and improves drop-test impact strength of the finished woven bag.
Every production batch undergoes automated spectrophotometer color matching (Delta E < 0.5), melt flow testing, and moisture analysis. We archive production samples for 24 months to ensure batch-to-batch repeatability for our global customers.
