What are the main performance indicators of BOPP thermal sensitive synthetic paper?

The main performance indicators of BOPP (biaxially oriented polypropylene) thermosensitive synthetic paper include the following aspects:

1、 Physical performance indicators

Quantitative:

Refers to the weight per square meter of paper, usually measured in grams per square meter (g/m ²). Quantification is an important factor affecting the thickness, strength, and printing effect of paper.

Thickness:

The thickness of paper, usually measured in millimeters (mm) or micrometers (μ m). The thickness is closely related to the quantity, and it also affects the printability and feel of the paper.

Tensile strength:

The maximum force that a paper can withstand when subjected to tensile force, usually measured in newtons per meter (N/m). Tensile strength reflects the strength and durability of paper.

Tear strength:

The force required for paper to propagate along a tear when subjected to tearing force, usually measured in millinewtons (mN). Tear strength reflects the toughness and tear resistance of paper.

2、 Chemical performance indicators

Water resistance:

The ability of paper to maintain its physical properties and printed content unchanged when exposed to moisture. BOPP thermal sensitive synthetic paper typically has good water resistance and can maintain label clarity and readability in humid environments.

Oil resistance:

The ability of paper to maintain its physical properties and printed content unchanged when in contact with grease. This is particularly important for labels that need to be used in oily environments.

Acid and alkali resistance:

The ability of paper to maintain its physical properties and printed content unchanged when in contact with acidic or alkaline substances. This is of great significance for labels that need to be used in special chemical environments.

3、 Printing performance indicators

Color rendering:

The response speed of the thermal coating to temperature changes and the degree of color change during thermal printing on paper. Paper with good color rendering can print clear and vivid images and text.

definition:

The clarity of printed images and text. The clarity is affected by various factors such as the flatness of the paper surface and the uniformity of the thermal sensitive coating.

Image preservation:

The ability of printed images and text to maintain their color and clarity after long-term storage. Paper with good image preservation can ensure the long-term readability of label information.

4、 Environmental performance indicators

Degradability:

The ability of paper to be decomposed by microorganisms in the natural environment. With the increasing awareness of environmental protection, biodegradability has become one of the important indicators of paper products.

Non toxic and harmless:

Paper refers to the process of production and use that does not pose a threat to human health and the environment. This requires that the paper raw materials and production processes must comply with environmental standards.

In summary, the main performance indicators of BOPP thermal sensitive synthetic paper cover multiple aspects such as physical properties, chemical properties, printing performance, and environmental performance. These indicators collectively determine the quality and effectiveness of paper, and are also important standards for measuring the quality of paper products.
