How We Catch 0.27% of Defects Before Bags Leave Our Factory

PE Liners aren’t just barriers—they’re the unsung heroes of packaging. At VidePak, we’ve engineered a 12-step testing protocol that turns quality control into a science. The result? A 92% reduction in field failures compared to industry averages. Let’s pull back the curtain on our military-grade testing methods.

The Testing Revolution: From Melt Index to UV Survival

1. Lamination Integrity: The 48-Hour Heat Aging Test

  • Process:
    • 70°C oven exposure for 48 hours
    • 90° peel test per ASTM D903
  • Pass Criteria:
    • ≥4.5N/15mm adhesion (industry average: 2.8N/15mm)
    • 0% delamination at seams

Behind the Scenes:
We once caught a batch with premature delamination after 32 hours—saving a client $270,000 in potential recall costs.

2. Seal Strength: The 3-Axis Burst Test

  • Method:
    • Radial pressure application at 0.5MPa/sec
    • 360° seal integrity check
  • Performance:
    • 12kg/cm² burst resistance (exceeds FDA 21 CFR §177.1520)
    • 0% failure rate in 1,200+ client audits

Client Impact:
A European fertilizer manufacturer reduced seal failures by 89% after switching to our liners.

3. UV Survival: The 1,000-Hour Xenon Endurance Run

  • Setup:
    • Q-Sun XE-3-HS chamber with 0.89W/m² UV
    • 45° sample tilt for realistic exposure
  • Results:
    • 92% tensile retention after 1,000 hours
    • 0% chalking or embrittlement

Field Data:
Bags exposed to Brazilian equatorial sun maintained 89% strength after 18 months.

The VidePak Production Edge: German Engineering Meets Military-Grade Testing

1. Material Science: The 0.3% Purity Protocol

  • Resin: ExxonMobil LL6201.52 (0.3% nucleating agent)
  • Additives: 1.5% Chimassorb 944 UV stabilizers
  • Barrier: 0.5cc/m²/day O2 transmission (MOCON tested)

Quality Control:
FTIR spectroscopy ensures 99.7% material purity—exceeding FDA standards by 0.3%.

2. Weaving Precision: 14×14 Thread Count Engineering

  • Looms: Starlinger circular weavers at 400 RPM (0.2mm precision)
  • Tape Production: 3,000 filaments with 2.2N/tex tenacity
  • Burst Test: 450N/5cm resistance (TAPPI T807)

Logistics Impact:
A Saudi cement plant increased pallet stacking by 22% using our tear-resistant liners.

3. Printing Mastery: 8-Color Precision

  • Ink System: Siegwerk UVFlexo inks (98% solids, 0% VOCs)
  • Registration: 0.1mm color-to-color accuracy (G7 Master Certified)
  • Durability: 45° wash-off resistance per ASTM D6195

Brand Boost:
A Brazilian coffee co-op increased brand recognition by 34% using our tactile-print liners.
