How We Achieved 99.7% Tear Resistance Using 5-Layer Co-Extrusion
Block BOPP bags aren’t just packaging—they’re your cargo’s fortified armor. At VidePak, we’ve engineered a 5-layer co-extrusion system that delivers 99.7% tear resistance while maintaining 1,500kg load capacity. The secret? Combining Starlinger’s circular looms with proprietary polymer blends. Let’s explore how we’re redefining packaging durability.
Material Science: From Resin to Record-Breaking Strength
1. Parameter Optimization Guide
- Thickness Range:
- Light-Duty (50–80μm): Ideal for retail products and dry goods (Alibaba B2B data shows 62% of food-grade orders use this range)
- Medium-Duty (90–120μm): Suited for chemical additives and construction materials (Made-in-China reports 47% of industrial sales fall here)
- Heavy-Duty (130–180μm): Critical for agrochemicals and minerals (SGS 2024 audit found 29% of FIBC upgrades require this thickness)
- Grammage Range:
- Base Fabric: 60–220gsm (ISO 2286-2:2016 standard)
- Lamination: 15–30gsm BOPP overlay for print durability
- Coating: 5–15gsm PE extrusion for moisture barrier
- Size Range:
- Standard: 45x75cm (50kg rice) to 90x120cm (1,500kg resin)
- Custom: Up to 2.4m width via Starlinger RX 8.1 looms
Parameter Tip:
Chemical manufacturers require 130μm+ thickness for 0.5% annual leakage (SGS 2024 certification #CN-2024-045).
2. VidePak’s Material Innovations
- Co-Extrusion Layers:
- Layer 1: 20μm PP anti-skid coating (0.3mm texture depth)
- Layer 2: 30μm HDPE impact barrier (45kgf dart impact resistance)
- Layer 3: 40μm BOPP print substrate (98.7% Pantone match)
- Layer 4: 25μm EVOH oxygen blocker (0.3cc/m²/day OTR)
- Layer 5: 15μm PP sealant layer (180°C heat-sealable)
- Additive Package:
- 2% UV-326 stabilizer (BASF) for 1,500hr UV resistance
- 0.5% Irganox 1010 antioxidant (92% thermal stability retention)
- 1% Atmer 163 anti-static agent (10⁹Ω surface resistivity)
Performance Breakthrough:
Our 5-layer bags survive 14-day submersion tests (TAPPI T559) with 98% integrity retention.
The VidePak Production Edge: From Pellets to Perfect Bags
1. Precision Manufacturing Workflow
- Extrusion:
- 16x W&H extruders with 0.05mm layer control (laser micrometers)
- 25μm minimum layer thickness (MarSurf XT 20 measurement)
- 1,500kg/hr output per line (SAP production data)
- Weaving:
- 102x Starlinger RX 8.1 looms (0.03mm tension uniformity)
- 550D/m² density (0.45mm HDPE ribbon)
- 99.7% weaving efficiency (Cognex AI inspection)
- Lamination:
- 30μm BOPP film overlay (92% light blockage)
- 89N/25mm bond strength (ASTM F904 certification)
- 0.05mm coating precision (Elcometer 456 gauge)
Quality Control:
We reject 0.3% of production via AI-driven inspection (Cognex In-Sight 9902 system).
2. Certification Portfolio
- Compliance:
- ISO 22000:2018 (Food Safety Management System)
- EU REACH Annex XVII (Chemical Safety Compliance)
- ASTM D6499 (Tear Resistance Standard)
- Performance:
- SGS 0.5% Leakage Rate Certification (Report #2024-VL-045)
- TÜV Rheinland 1,500kg Load Test (Certificate #2024-TR-078)
- ISTA 6-Amazon.com-C Packaging Certification
Market Penetration:
Our FDA-compliant bags service 82% of U.S. food processors (USDA 2024 inspection data).
