7 Layer Advantage: Beyond the Layer

3 Layer vs 7 Layer
Blended Layers = Compromise
In a typical 3 layer bag, all of the characteristics of the bag are blended together in three layers. From the outer to the inner layers of the bag, the layers are blends of polymers designed to provide temperature reduction (white), mechanical strength, and sunlight blocking (black). Blended layers result in a trade-off between benefits. Easy to process polymers that are not very tough are blended with tougher polymers that are harder to process, resulting in compromised characteristics. These bags are often produced thicker and stiffer to compensate for the less beneficial blends, while not reaching optimal performance.
Individual Layers = Optimal Performance
With the AgFlex 7 Layer SmartStructure® Technology, each layer of polymer is designed to provide the full benefit of its characteristics. 7 layers allows each polymer to be added neat, or un-blended, providing dedicated layers for tear resistance, puncture resistance, and stiffness to prevent slumping. One polymer is not blended with another, so they do not offset one another's beneficial characteristics. Bags do not have to be made excessively thick or stiff to compensate, resulting in less waste.
