How to identify the quality of BOPP color synthetic paper?

The quality of BOPP color synthetic paper can be identified from the following aspects:

1、 Appearance quality inspection

Color and Gloss:

High quality BOPP color synthetic paper should have uniform and bright colors, without obvious color differences or spots.

Observing the glossiness of the paper surface, high-quality paper should have a moderate luster, neither too dazzling nor too dull.

Flatness and smoothness:

Touch the surface of the paper with your hands and feel its flatness and smoothness. The surface of high-quality paper should be flat and smooth, without obvious unevenness.

Observe whether the edges of the paper are neat, without curling or wrinkling.

Impurities and foreign objects:

Carefully inspect the surface of the paper for impurities or foreign objects such as dust, spots, holes, holes, folds, wrinkles, broken sheets, corners, dirty spots, foam gauze, pulp blocks, and other hard blocks.

2、 Physical performance testing

Tensile strength and toughness:

Evaluate the strength and toughness of paper through tensile testing. High quality BOPP color synthetic paper should have high tensile strength and toughness, and be not easily broken.

Tear resistance:

Gently rub or shake the paper with your hands and observe if there are any cracks appearing. High quality paper should have good tear resistance and be not easily damaged.

Waterproof performance:

Evaluate the waterproof performance of paper to ensure its stability in humid environments. High quality BOPP colored synthetic paper usually has good waterproof performance.

3、 Thermal performance test

Thermal reaction speed:

Use a thermal printer for testing and observe the reaction speed of paper to heat. High quality paper should have a fast thermal response speed and be able to quickly produce clear images or text.

Color stability:

Observe the color stability of the printed image or text. High quality BOPP color synthetic paper should have stable color performance and not easily fade or discolor.

4、 Environmental performance evaluation

Material environmental friendliness:

Understand the raw material sources and production processes of paper to ensure that it meets environmental requirements. High quality BOPP color synthetic paper should be produced using environmentally friendly materials and have no pollution during the production process.

Recyclability:

Evaluate the recyclability of paper and determine if it can be recycled to reduce its impact on the environment.

5、 Professional testing and identification methods

Chemical analysis:

Detect the additive composition and content in paper through chemical analysis methods to evaluate its quality and safety.

Instrument testing:

Use professional testing instruments to test and evaluate various performance indicators of paper, such as tensile strength tester, tear tester, glossiness tester, etc.

True and False Identification Technology:

For some specific application scenarios (such as anti-counterfeiting packaging), professional authenticity identification techniques can be used to evaluate the quality of BOPP colored synthetic paper. For example, gas chromatography-mass spectrometry (GC-MS) technology is used to fully scan the extract of additives in paper, identify the characteristic spectral segments that distinguish between genuine and fake, and thus determine the authenticity of the paper.

In summary, identifying the quality of BOPP color synthetic paper requires comprehensive consideration of multiple aspects such as appearance quality, physical properties, thermal sensitivity, environmental performance, and professional testing and identification methods. By comprehensively comparing and evaluating the advantages and disadvantages of different products, one can choose high-quality BOPP color synthetic paper that meets their own needs.
