What are the performance requirements of BOPP synthetic paper for making tags?

For the production of tags, the performance requirements of BOPP synthetic paper mainly include the following aspects:

First, physical properties

1. Strength and toughness:

BOPP synthetic paper should have sufficient tensile strength and tear resistance to ensure that the tag is not easily broken or torn during use. This helps to improve the durability and reliability of the tag.

2. Dimensional stability:

Good dimensional stability, can maintain the stability of shape and size under different temperature and humidity conditions, avoid deformation or curling due to environmental changes, so as to ensure the beauty and functionality of the tag.

Second, printing performance

1. Printability:

The surface of the BOPP synthetic paper should be smooth and smooth, and it has good adsorption and adhesion to the ink to ensure that the printing pattern and text are clear, colorful and not easy to fall off. This helps to improve the visual effect and brand image of the tag.

Since the surface of BOPP film is non-polar, high crystallinity and low surface free energy, surface corona treatment or other pretreatment may be required before printing to improve its printing performance.

2. Color reducibility:

It should have good color reducibility, and be able to accurately reproduce the colors and patterns in the design draft, so that the tag is more realistic and vivid.

Third, appearance and texture

1. Appearance texture:

The appearance should be smooth and smooth, without obvious defects and defects, giving people a high-grade and professional impression.

Matte BOPP synthetic paper also has a paper-like texture and touch, which can enhance the overall texture and feel of the tag.

2. Transparency and gloss:

According to the need, BOPP synthetic paper can have different transparency and gloss. For tags that need to display product information, BOPP synthetic paper with higher transparency can be selected; For the pursuit of texture and high-grade tag, you can choose a moderate gloss of the product.

Fourth, durability

1. Waterproof and moisture-proof:

BOPP synthetic paper should have good waterproof and moisture-proof properties, be able to maintain dry and stable in a humid environment, and avoid deformation or damage caused by water erosion.

2. Chemical resistance:

It should be able to resist the corrosion of a certain concentration of acids, alkalis and other chemicals to ensure that the tag can maintain good performance and appearance in a variety of use environments.

Fifth, environmental protection

With the improvement of environmental awareness, more and more consumers and enterprises begin to pay attention to the environmental performance of products. Therefore, the BOPP synthetic paper used to make the tag should be as environmentally friendly as possible to choose the material and production process to reduce the impact on the environment.

In summary, the BOPP synthetic paper used to make the tag needs to have good physical properties, printing performance, appearance and texture, durability and environmental protection requirements. The satisfaction of these performance requirements will help to improve the overall quality and market competitiveness of the tag.
