The Science Behind Heavy Duty PE Bags Roll Thickness Selection
Heavy duty PE bags roll film thickness directly correlates with load-bearing capacity, puncture resistance, and environmental durability. Typically ranging from 50μm to 300μm, each thickness grade addresses specific operational requirements:
1.1 Thickness-Performance Matrix
| Film Thickness | Typical Applications | Tensile Strength (MD/TD) | Puncture Resistance | Optimal Load Capacity |
|---|---|---|---|---|
| 50–80μm | Light-duty retail packaging | 15–25 MPa | 2.5–4.0 N | <10kg |
| 100–150μm | Agricultural produce, industrial parts | 30–40 MPa | 6.0–8.5 N | 10–25kg |
| 180–250μm | Construction materials, chemicals | 45–60 MPa | 10.0–15.0 N | 25–50kg |
| 300μm+ | Mineral concentrates, hazardous waste | 65–80 MPa | 18.0+ N | 50kg+ |
Engineering Insight: VidePak’s FFS HDPE Film employs 5-layer co-extrusion to achieve 60 MPa tensile strength at 180μm – a 20% improvement over mono-layer equivalents (tested per ASTM D882).
1.2 Thickness Selection Framework
- Load Analysis: Calculate product density, stack height, and handling dynamics
- Environmental Exposure: Assess UV exposure, humidity, and chemical contact
- Cost-Benefit Analysis: Balance material costs against expected waste reduction
Client ROI: A Brazilian fertilizer distributor reduced film costs by 12% by switching from 200μm to 150μm rolls after VidePak’s engineers demonstrated equivalent performance in humid conditions (SGS-audited 90-day field test).
2.1 VidePak’s Quality Assurance Protocol
2.1.1 Mechanical Property Testing
- Tensile Strength: ASTM D882-compliant Instron 5967 machine at 500mm/min
- Elmendorf Tear Resistance: 200–1,000 grams force measurement (ASTM D1922)
- Impact Resistance: 1.5m drop testing on concrete (ISO 7765-1)
Certification Highlight: SGS report CN2024/0567 confirms 45 MPa tensile strength for 180μm FFS Roll Films – 15% above industry averages.
2.1.2 Thermal & Environmental Testing
- Heat Seal Strength: 160–220°C sealing bars with 2.0–4.0N/15mm targets (ASTM F88)
- UV Resistance: QUV accelerated weathering (ASTM G154) for 1,000 hours
- Aging Simulation: 90-day oven testing at 50°C/90% RH (ISO 188)
Technical Edge: VidePak’s Form-fill-seal Films retain 92% original tensile strength after 500 hours UV exposure – critical for East Africa’s equatorial climates.
2.1.3 Dimensional & Aesthetic Controls
- Thickness Tolerance: ±2μm via ultrasonic gauges (ISO 4593)
- Edge Quality: Laser-based毛边检测 systems rejecting >0.5mm defects
- Color Consistency: ΔE <1.5 via X-Rite SpectroEye (CIEDE2000 formula)
3.1 Advanced Seal Integrity Testing
FFS Tubular Polyethylene Films require flawless seal integrity for automated packaging lines. VidePak’s protocols include:
- Burst Testing: 300 kPa internal pressure resistance (ASTM D3786)

- Leak Detection: Helium spectrometer scanning for 0.1mm micro-leaks
Case Study: A Japanese pet food manufacturer eliminated 98% of seal failures by adopting VidePak’s 3-stage seal validation, which includes:
- Pre-production mock-ups on client’s exact FFS machinery
- Real-time pressure decay testing during production
- Post-production vacuum leakage analysis
