When Pallet Stability Meets High-Speed Filling
Block bottom valve bags are rewriting logistics efficiency—enabling 1.8 million metric tons of cargo to move weekly with 99.9% stability. At VidePak, we engineer these bags with patented valve geometries and laser-cut bases to optimize pallet density for Nestlé, LafargeHolcim, and 300+ global clients. These aren’t ordinary sacks—they’re logistics optimization systems for cement, chemicals, and food-grade powders. Let’s explore how we blend material science with supply chain innovation.
Precision Engineering: 3 Parameters for Perfect Logistics
1. Thickness Optimization (80μm – 300μm)
We engineer:
- 80μm Bags: For 25kg food powders (5% moisture resistance)
- 150μm Bags: For 50kg chemicals (30% thicker at valve joints)
- 300μm Bags: For 1,500kg cement (6:1 safety factor)
Engineer’s Insight:
“Our variable-thickness design reduces material use by 22% vs. flat specifications,” says R&D Director Li Wei.
2. Grammage Control (60gsm – 220gsm)
We balance:
- 60gsm Fabrics: For dry goods (30% lighter than industry average)
- 120gsm Fabrics: For abrasive minerals (40% higher tear strength)
- 220gsm Fabrics: For sharp-edged aggregates (ISO 13934-1 certified)
Case Study:
A Chilean copper producer reduced bag failures by 82% using our 220gsm solution.
3. Dimensional Accuracy (35cmx50cm – 75cmx110cm)
We calibrate:
- 35cmx50cm Bags: For 25kg food powders (98% pallet fill rate)
- 50cmx80cm Bags: For 50kg chemicals (40% faster filling)
- 75cmx110cm Bags: For 1,500kg cement (20% more pallets per truck)
Field Test:
A German chemical distributor increased trailer loads by 22% using our 50cmx80cm bags.

2. Weaving: The 18-Pick Density Breakthrough
Our circular looms create:
- 18 Picks/cm²: 50% denser than industry norms
- Bias-Cut Resistance: 95% reduction in fraying (ASTM D5034)
Case Study:
A Brazilian cement producer reduced bag replacements by 42% using our 18-pick fabrics.
3. Lamination: The 3-Layer Barrier System
Our W&H laminators apply:
- BOPP Film: 18μm thickness for waterproofing
- EVOH Barrier: 0.015mm layer for oxygen blocking
- Antimicrobial Coating: Silver ion treatment for food safety
Field Test:
A Japanese seafood exporter extended shelf life by 12 months using our laminated bags.
4. Quality Control: The 23-Point Inspection
We verify:
- Drop Test: 14-foot survival (ISO 2248)
- Seal Strength: 18 N/15mm minimum (ASTM F88)
- UV Stability: 2,000-hour accelerated aging
VidePak Certification:
