Definition and relevance
420D PU Coated Fabric, specifically in the context of bag manufacturing, refers to a type of fabric that is commonly used for producing durable and functional bags. It is composed of a base fabric known as 420D Oxford fabric, which is coated with a layer of Polyurethane (PU) on one or both sides.The “420D” in the fabric’s name represents the denier measurement, which refers to the thickness and weight of the fibers used in the fabric.Overall, 420D PU Coated Fabric is a popular choice in bag manufacturing due to its combination of strength, water resistance, lightweight nature, and customization possibilities.
Choosing the Right 420D PU Oxford Fabric for Bags
Factors
Strength and Durability:
Evaluate the fabric’s tensile strength and tear resistance to ensure it can withstand the demands of bag usage.
Consider the expected load and stress the bag will endure, especially for heavy-duty or outdoor applications.
Look for reinforced fibers or additional coatings that enhance durability.
Water Resistance:
Assess the level of water resistance provided by the PU coating to protect the bag’s contents.
Determine if the fabric is water repellent or fully waterproof, depending on the specific requirements of the bag.
Consider the seam construction and zippers to ensure water cannot penetrate through them.
Weight and Thickness:
Consider the weight of the fabric to ensure it aligns with the desired lightweight nature of the bag.
Evaluate the fabric’s thickness to balance durability with the desired weight.
Remember that a lighter fabric may sacrifice some durability, so finding the right balance is crucial.

Certifications and Standards:
Check if the supplier adheres to industry standards and holds relevant certifications for fabric production.
Certifications such as ISO, Oeko-Tex, or REACH can provide assurance of quality and compliance.
Consider if the supplier can provide certificates of conformity or test reports for the fabric.
Customization Options:
Determine if the supplier offers customization options such as color matching, printing, or additional treatments.
Assess their ability to meet specific requirements for bag manufacturing, such as providing fabric samples with custom prints or finishes.
Requesting Fabric Samples
Sample Evaluation:
Evaluate the fabric samples based on the desired factors mentioned earlier, such as strength, water resistance, weight, and aesthetics.
Test the fabric’s performance by subjecting it to simulated bag usage or relevant environmental conditions.
Assess the samples for any defects, inconsistencies, or variations in quality.
Compare Multiple Samples:
Request samples from multiple suppliers to compare and assess the variation in fabric quality, appearance, and performance.
Consider the consistency of the fabric samples from different batches to ensure reliability.
Use the samples to make an informed decision on the most suitable fabric for the intended bag manufacturing.
