The innovation of BOPP synthetic label paper in technology and performance is mainly reflected in the following aspects:
First, technological innovation
1.Improvement of production process:
Bidirectional drawing technology: BOPP synthetic label paper is made of bidirectional drawing process, which can significantly improve the mechanical strength and dimensional stability of the film, so that the label paper performs well in the high-speed automated labeling process.
Multi-layer co-extrusion technology: Some high-end BOPP synthetic label paper adopts multi-layer co-extrusion technology, which gives the label paper more functions, such as waterproof, moisture-proof, oil resistance, tear resistance and so on, through the combination of different materials.
2.Optimization of material formulation:
By adjusting the formula of polypropylene resin, BOPP synthetic label paper with different properties can be produced to meet the needs of different industries and application scenarios. For example, adding antistatic agents can improve the antistatic performance of the label paper, reduce electrostatic adsorption and dust pollution.
3.Surface treatment technology:
Corona treatment: The BOPP film needs to be corona treated before gluing or printing to improve its surface energy, enhance the adhesion of the ink or glue, and make the label paper have better printing and labeling effects.
Other surface treatment techniques: such as coating, embossing, etc., can increase the visual effect and touch of the label paper, and improve the overall texture of the product.
Second, performance innovation
1.Physical performance improvement:
High strength: BOPP synthetic label paper has excellent tensile strength and impact strength, can withstand greater external force and impact, not easy to break.
Stable size: In the case of changes in environmental conditions such as temperature and humidity, BOPP synthetic label paper can still maintain a stable size to ensure the accuracy of labeling.
2.Enhanced chemical stability:
BOPP synthetic label paper has excellent chemical stability, can resist the erosion of a variety of chemical substances, such as acid, alkali, oil, etc., to ensure that the label is used in a complex environment for a long time without deterioration.
3.Functional expansion:
Waterproof and moisture-proof: BOPP synthetic label paper has good waterproof and moisture-proof properties, which can maintain the clarity and integrity of the label in a humid environment.
Oil and tear resistance: Some high-end BOPP synthetic labels also have oil and tear resistance characteristics, which can be used in oil-bearing environments or harsh conditions for a long time without being affected.
Environmental protection: With the improvement of environmental awareness, more and more BOPP synthetic label paper is made of degradable materials to reduce environmental pollution.
4.Improvement of printing adaptability:
BOPP synthetic label paper has good printing adaptability and can accept a variety of printing technologies, such as flexographic printing, relief printing, offset printing, etc., and the printed label pattern and text are clear and beautiful.
In summary, the innovation of BOPP synthetic label paper in technology and performance is mainly reflected in the improvement of production process, the optimization of material formulation, the application of surface treatment technology, and the improvement of physical properties, chemical stability, functionality and printing adaptability. These innovations not only improve the quality and performance of BOPP synthetic label paper, but also broaden its application field and market prospects.
