How to judge the quality of BOPP color synthetic paper?

To judge the quality of BOPP color synthetic paper, the following aspects can be comprehensively considered:

1、 Physical characteristics

Dimensional stability:

High quality BOPP color synthetic paper should have excellent dimensional stability and be not easily deformed. This can be evaluated by observing the size changes of the paper during long-term storage or under different environmental conditions.

Mechanical strength:

High quality BOPP color synthetic paper should have high tear strength and bending fatigue resistance. The mechanical strength can be preliminarily determined through simple tearing and bending tests.

Stiffness:

High stiffness BOPP color synthetic paper can maintain good shape and stability during printing and use. The stiffness of paper can be evaluated by touching and observing its flatness and rigidity.

Transparency and glossiness:

Before being subjected to thermal reactions, high-quality BOPP colored synthetic paper should have a clear transparent substrate and high glossiness. The transparency and glossiness of paper can be evaluated by detecting light transmission and observing the surface gloss of the paper.

2、 Thermal reactivity performance

Brightness and durability of colors:

High quality BOPP color synthetic paper should be able to quickly produce bright and long-lasting colors after being heated. The color vividness and durability can be evaluated by printing test samples and observing their color changes over different time periods.

Thermal reaction speed:

High quality BOPP color synthetic paper should have a fast thermal reaction speed, which can produce clear images or text in a short period of time. The thermal reaction performance can be evaluated by printing test samples and observing their printing speed and quality.

3、 Safety and environmental protection

Non toxic, odorless, and tasteless:

High quality BOPP color synthetic paper should meet safety and environmental protection requirements, be non-toxic, odorless, and tasteless. You can confirm its safety and environmental friendliness by reviewing the product manual or relevant certification information.

Moisture resistance:

High quality BOPP color synthetic paper should have excellent moisture resistance and be able to effectively isolate moisture. The moisture resistance of paper can be evaluated by observing its changes in a humid environment.

4、 Printing performance

Printing adaptability:

High quality BOPP color synthetic paper should have good printing adaptability and be able to achieve exquisite appearance effects. Its printing performance can be evaluated through actual printing tests.

Ink adhesion:

High quality BOPP color synthetic paper should have strong ink adhesion to ensure that printed content is not easily peeled off or blurred. The ink adhesion can be evaluated by printing test samples and observing their ink adhesion.

5、 Other considerations

Production cost and price:

Although production cost and price are not direct criteria for judging the quality of BOPP colored synthetic paper, excessively high prices may mean unnecessary waste, while excessively low prices may mean compromises in quality. Therefore, when making a choice, it is necessary to consider both actual needs and budget comprehensively.

Brand and reputation:

Choosing well-known brands and suppliers with good reputations can usually provide more assurance in obtaining high-quality BOPP color synthetic paper. You can learn about brand and reputation information by consulting relevant materials or professionals.

In summary, judging the quality of BOPP color synthetic paper requires comprehensive consideration of multiple aspects. In the actual purchase and use process, it is recommended to choose and evaluate based on specific needs and conditions.
