What is the difference between three proof thermal paper and one proof thermal paper?

The main differences between three proof thermal paper and one proof thermal paper are reflected in the following aspects:

1、 Waterproof performance

One proof thermal paper: It has certain waterproof performance, but here waterproofing only refers to a trace amount of water. Thermal resistant paper can resist small amounts of moisture in daily life, such as water droplets or humidity, but prolonged soaking or exposure to large amounts of moisture may cause damage to the paper.

Three proof thermal paper: It also has waterproof performance, and the waterproof effect is usually better than that of first proof thermal paper. Three proof thermal paper can better resist moisture erosion and is suitable for more scenarios that require waterproof protection.

2、 Oil resistance performance

Thermal resistant paper: usually does not have oil resistance or has weak oil resistance. In environments with high levels of grease, thermal paper may be contaminated or damaged.

Three proof thermal paper: It has significant oil resistance. In oily environments, three proof thermal paper can maintain clarity and integrity, making it suitable for places with high oil content such as kitchens and restaurants.

3、 Anti PVC/scratch performance

Thermal resistant paper: usually does not have PVC or scratch resistance properties. This means that when a heat-resistant paper comes into contact with PVC material (such as cling film), the printed information may gradually disappear. Meanwhile, heat-resistant paper is also more susceptible to physical scratches.

Three proof thermal paper: not only waterproof and oil resistant, but also has PVC (sometimes including alcohol and scratch resistance) properties. This enables the three proof thermal paper to maintain the clarity of printed information when in contact with PVC material, while also being more durable and less susceptible to physical damage.

4、 Glue and stickiness

Thermal resistant paper: usually uses water-based adhesive, which leaves less residue when peeled off after pasting, but may have weaker adhesion, making it suitable for relatively flat labeling surfaces.

Three proof thermal paper: generally using hot melt adhesive with stronger viscosity, suitable for labeling substrates with uneven surfaces. Although there may be some residue left when torn off, stronger adhesion ensures the stability of the label.

5、 Price and application scenarios

Price: The price of first proof thermal paper is usually lower than that of third proof thermal paper because it is more complex in terms of materials and processes.

Application scenario: One proof thermal paper is suitable for scenarios with certain requirements for waterproof performance but not too strict, such as ordinary retail, logistics transportation, etc. And the three proof thermal paper is more suitable for scenarios that require high waterproof, oil proof, and PVC resistant performance, such as supermarket cooked food areas, kitchen appliance labels, etc.

In summary, the three proof thermal paper is superior to the one proof thermal paper in terms of waterproofing, oil resistance, and PVC/scratch resistance. At the same time, it has stronger adhesion, but the price is relatively higher. When making a choice, a balance should be made based on specific application scenarios and requirements.
