To the untrained eye, a white courier bag is just a piece of plastic. But for the e-commerce professional, the material is a high-tech barrier. At Ragi Packaging, our 60-micron courier bags are manufactured using a process called 3-Layer Co-Extrusion. Here is why this manufacturing secret matters for your business.
1. The Opaque Inner Core (Black Layer)
Have you ever noticed that our bags are white on the outside but black on the inside? This isn't just for looks.
-
The Function: The middle and inner layers are infused with black carbon pigment. This creates 100% opacity. Even if a thief holds your package up to a high-powered warehouse light, they cannot see if there is a smartphone, a piece of jewelry, or a private document inside. Privacy is the first step in security.
2. The Weather-Resistant Outer Shell (White Layer)
The outer layer is treated with a specialized "corona treatment" and high-grade TiO2 (Titanium Dioxide).
-
The Benefit: This makes the bag moisture-resistant and reflective. It protects your products from the light rain during bike deliveries and prevents the contents from overheating when sitting in a delivery van under the Indian sun. Plus, it provides the perfect surface for your shipping labels to stick without peeling.
3. High-Tensile Strength & Tear Resistance
Because the bag is made of three distinct layers of film fused together, it has much higher "puncture resistance" than a single-layer bag of the same thickness.
-
The Physics: If a sharp corner of a box pokes the inner layer, the outer layers act as a reinforcement to prevent the hole from "running" or turning into a massive tear. This is why our 60-micron bags can carry heavy clothing or books without stretching out of shape.
4. Consistent Micron Calibration
In the local market, "60 microns" is often just a claim. In reality, the thickness might vary across the bag.
-
The Ragi Standard: Our co-extrusion process uses computer-controlled sensors to ensure the thickness is uniform across every square inch of the bag. Whether it's a small 10x12 or a massive 25x28, you get the same industrial-grade protection.
