Improving the wear resistance of BOPP (biaxially oriented polypropylene) synthetic label paper can be approached from the following aspects:
1、 Select high-quality materials
Substrate selection: Choose high-strength and wear-resistant BOPP film as the substrate, which is the basis for improving wear resistance. High quality BOPP film has better physical properties and chemical stability, and can withstand more friction and wear.
Additive usage: In the production process of BOPP film, some wear-resistant enhancers can be added, such as wear-resistant fillers, wear-resistant resins, etc. These additives can significantly improve the wear resistance of the film.
2、 Optimize production process
Coating treatment: Coating a layer of wear-resistant coating on the surface of BOPP film can effectively improve the wear resistance of label paper. Wear resistant coatings can be selected from resins or coatings with excellent wear resistance, such as polyurethane, acrylic, etc. By optimizing the coating formula and coating process, it is possible to ensure good adhesion between the coating and BOPP film, while improving wear resistance.
Surface modification: Surface modification treatment of BOPP film, such as plasma treatment, chemical etching, etc., can improve the roughness and polarity of the film surface, thereby enhancing its adhesion and wear resistance with wear-resistant coatings.
3、 Post processing technology
Film coating treatment: Covering the surface of the label paper with a transparent film, such as PET film, PP film, etc., can provide protection and prevent direct wear and tear of the label paper. At the same time, transparent film can also increase the glossiness and aesthetics of label paper.
UV curing: For label paper coated with wear-resistant coating, UV curing process can be used for curing treatment. UV curing can quickly crosslink and cure the resin or coating in the coating, forming a hard wear-resistant layer, thereby improving the wear resistance of the label paper.
4、 Storage and usage precautions
Suitable environment: Store the label paper in a dry, cool, well ventilated place, away from direct sunlight and humid environment. Meanwhile, avoid prolonged exposure of label paper to extreme temperature or humidity conditions to maintain its optimal performance.
Correct construction: During the labeling process, the correct construction method should be used to ensure that the label paper is completely adhered to the object being glued, reducing the possibility of detachment and wear. At the same time, avoid excessive stretching or twisting of the label paper during the labeling process to avoid damaging its structure and reducing its wear resistance.
5、 Wear resistance testing and evaluation
Wear resistance test: Regularly conduct wear resistance tests on BOPP synthetic label paper to evaluate whether its wear resistance meets the requirements. The testing method can use a friction testing machine to simulate friction testing and observe the wear of the label paper during the friction process.
Quality monitoring: Strengthen the quality monitoring of raw materials, production processes, and post-treatment processes during the production process to ensure that each batch of label paper has stable wear resistance.
In summary, by selecting high-quality materials, optimizing production processes, post-processing techniques, paying attention to storage and usage conditions, and conducting wear resistance testing and evaluation, the wear resistance of BOPP synthetic label paper can be effectively improved. This will help extend the lifespan of label paper and improve its stability and reliability in various environments.
