About the work:
As a basic and innovative technology in the field of packaging materials, BOPP pre-coated film has attracted more and more attention for its excellent performance and wide application. This paper will deeply discuss the characteristics, production process and application prospect of BOPP hot film in packaging industry.
1. Basic introduction of BOPP pre-coating film
BOPP pre-coated film is a composite functional film made of biaxial oriented polypropylene film (BOPP) as the substrate and extruded by a special coating process with a layer of EVA. This extrusion film production process makes the BOPP pre-coated film with good transparency, flatness and excellent wear resistance, making it widely used in the packaging industry.
2. Performance characteristics of BOPP pre-coated film
High transparency :BOPP pre-coated film can do matte and smooth surface, smooth surface has excellent transparency, can make the packaging of the original text printing and other clearly visible, and protect the color of the packaged product durable, improve the appearance of the product appeal.
Good flatness: The surface of the packaged product is very flat after the film is covered, the folding is not foaming, and it is not easy to open the glue, so that the printing effect of the pattern text is more bright and clear.
Good wear resistance :BOPP pre-coated film is specially treated to enhance surface hardness and wear resistance, protecting the integrity of the packaged items.
3. BOPP thermal film production process and technical points
The production process of BOPP thermal film includes film extrusion, biaxial drawing, EVA coating, etc., and different special treatments can be added according to the needs of customers in different scenarios. Among them, the extrusion process and coating process are the key links, which need to ensure the uniformity and adhesion of the material.
4. Application prospect of BOPP thermal film in packaging industry
The excellent characteristics of BOPP thermal film make it widely used in the packaging and printing industry, especially in the fields of food, daily cosmetics, cosmetics, medicine and so on. Widely used in packaging bags, bottle labels and other products surface protection and decoration. With the enhancement of people's environmental awareness, BOPP thermal film is gradually developing degradable direction, and can be used at present, with good market prospects.
Conclusion:
BOPP thermal film has become an innovative choice in the packaging industry with its excellent performance characteristics and broad application prospects. With the continuous progress of technology and the increase of market demand, I believe that BOPP thermal film will achieve more brilliant achievements in the future, bringing more convenience and innovation to the packaging industry.
