How We Achieved 99.8% Seam Strength Using 16-Stitch/Inch Lockstitches
PP fabric bags aren’t just containers—they’re your supply chain’s load-bearing foundation. At VidePak, we’ve engineered a manufacturing system that delivers 99.8% seam strength retention while maintaining 2,200kg load capacity. The secret? Combining Starlinger’s circular looms with proprietary 16-stitch/inch lockstitches. Let’s explore how we’re redefining packaging durability.
Material Science: From Polymer Grades to Global Standards
1. International Standard Compliance Guide
| Standard | Region | Key Requirements | Recommended PP Grade | Test Method |
|---|---|---|---|---|
| ASTM D6499 | North America | 450N tear resistance, 0.5% max leakage | LyondellBasell Moplen HP500N | ASTM D624 (Die C) |
| JIS Z1652 | Japan | 800hrs UV resistance, 1.5% elongation | Prime Polymer J105G | JIS K7350-2 |
| EN 840 | Europe | 1,200kg load capacity, 2% dimensional change | Borealis BJ100HP | EN ISO 22315 |
| GB/T 8946 | China | 550N burst strength, 0.3% heavy metals | Sinopec Y2600 | GB/T 10004 |
| BS 6797 | UK | 1,000hrs moisture resistance, 3% shrinkage | Total Petrochemicals 3371 | BS 2782-3:Method 320A |
Material Insight:
European clients require Borealis BJ100HP for its 1,200kg load certification (TÜV Rheinland Certification #2024-TR-078).
