Iron – on barcode labels are typically made of the following materials:
Base Material
Polyester: It is a common choice for its durability, resistance to wrinkles, and ability to withstand high temperatures. Polyester – based labels can maintain their shape and the integrity of the barcode during the iron – on process and in subsequent use.
Nylon: Nylon is known for its strength and flexibility. Labels made of nylon are less likely to tear or crack, even when subjected to repeated bending and stretching, which is beneficial for items that may be folded or moved frequently.
Coating Material
Thermal Transfer Coating: This coating is applied to the surface of the label to enable the printing of the barcode and other information. It is designed to react to the heat from a thermal transfer printer, allowing for clear and accurate printing. The coating also helps protect the printed barcode from fading, smudging, and abrasion, ensuring its long – term readability.
Protective Coating: A clear protective coating is often applied over the printed barcode and label surface. This coating provides additional protection against moisture, chemicals, and physical damage. It can enhance the label’s resistance to fading and scratching, maintaining the barcode’s integrity in various environmental conditions.
Adhesive Material
Heat – Activated Adhesive: The adhesive used on iron – on barcode labels is specifically formulated to activate when exposed to heat. When the label is ironed onto an item, the heat causes the adhesive to melt and bond firmly with the surface of the material. This type of adhesive provides a strong and durable bond that can withstand washing and regular use without the label peeling off.
FAQ
The two most common base materials are polyester and nylon. Polyester is chosen for its high-temperature resistance and durability, ensuring the label maintains its shape and barcode integrity during the heat-application process. Nylon is preferred for its flexibility and strength, making it ideal for items that undergo frequent folding or stretching, as it is less likely to crack or tear.
Iron-on barcode labels use a specialized heat-activated adhesive. When heat is applied via an iron or heat press, the adhesive melts and creates a firm bond with the fabric’s surface. This formulated adhesive is designed to provide a strong, durable permanent bond that can withstand regular use and repeated washing cycles without peeling or lifting.
