Poly Woven Bags and Poly Fabric sacks are pivotal in modern packaging, providing durability, flexibility, and environmental sustainability. As a leading manufacturer, VidePak ensures the highest quality standards by adopting industry-leading testing protocols for our Woven Polypropylene Bags. These tests assess parameters such as tensile strength, tear resistance, thermal sealing, and UV protection. Our commitment to rigorous quality control is evident through comprehensive assessments including thickness tolerance, edge smoothness, color variance, and weight accuracy.
To understand the depth of our approach, we explore key quality tests and their role in maintaining excellence in Poly Bags production. For further insights on Poly Woven Bags, visit our dedicated page here. Similarly, discover more about Poly Fabric sacks by exploring our expertise here.
Tensile Strength and Elongation Testing
Ensuring Poly Bags can endure substantial loads without deformation is critical. Tensile strength tests measure the maximum stress a material can withstand when stretched. We conduct these tests on both raw yarns and finished products, ensuring high-performance metrics:
| Parameter | Raw Yarn | Finished Product |
|---|---|---|
| Tensile Strength (MPa) | ≥35 | ≥30 |
| Elongation (%) | 15-20 | 10-15 |
The tests simulate real-world conditions to prevent failures during storage or transport.
Tear Resistance and Edge Smoothness
Tear resistance ensures Woven Polypropylene Bags withstand punctures and abrasions. Additionally, edge smoothness testing ensures cuts in the bags are free from jagged edges, enhancing usability.
Testing Methodology:
- A uniform force is applied to evaluate tear propagation resistance.
- Edges are visually inspected and measured using micrometers for burr-free cuts.
This precision prevents product loss, particularly in bulk and industrial packaging applications.
Thermal Sealing and Thickness Tolerance
The heat-sealing process directly influences the structural integrity of Poly Fabric sacks. Testing thermal seals involves evaluating bond strength under various temperatures.
Thickness uniformity is equally critical. Uneven material thickness compromises strength and flexibility. VidePak utilizes laser-guided micrometers to maintain thickness tolerances within ±0.05 mm.
| Parameter | Specification | Test Tolerance |
|---|---|---|
| Seal Strength (N/15mm) | ≥20 | ±2 |
| Thickness (mm) | 0.15-0.18 | ±0.05 |
Color and Weight Consistency
Consistency in visual and weight parameters ensures a professional finish and operational efficiency.
Procedures for Testing:
- Color Matching: Advanced spectrophotometers ensure uniform color tones for branding and labeling.
- Weight Accuracy: Bags are weighed post-production to ensure conformity to specified metrics.
| Test Metric | Standard | Acceptable Deviation |
|---|---|---|
| Color Delta (ΔE) | ≤2.0 | ≤1% |
| Weight (g) | Varies by product | ±1% |
UV Resistance and Anti-Aging Tests
Exposure to sunlight can degrade Woven Polypropylene Bags, especially in outdoor applications. Our UV resistance tests simulate prolonged exposure to ultraviolet light, assessing durability over extended periods.
Anti-Aging Parameters:
- Exposure to 500 hours of UV light ensures longevity.
- Chemical additives like HALS (Hindered Amine Light Stabilizers) enhance lifespan.
| Test Parameter | Benchmark | Testing Duration |
|---|---|---|
| UV Retention (%) | ≥90 | 500 hrs |
Comprehensive Quality Assessments
VidePak also prioritizes additional quality checks:
- Cut Edge Analysis: Prevents loose threads and bag splitting.
- Weight Per Unit Area: Ensures material density is consistent.
| Additional Test | Standard | Purpose |
|---|---|---|
| Weight Per Unit Area | ±5% of target | Ensures strength |
| Cut Edge Integrity | No fraying | Prevents spillage |
