What are the main raw materials for BOPP color synthetic paper?

The main raw material for BOPP color synthetic paper (usually referred to as BOPP color thermosensitive synthetic paper) is polypropylene (PP) resin, especially isotactic polypropylene. Its content needs to reach a high standard (such as 95%~97%) to ensure the tensile strength and physical properties of the film. The following is a detailed analysis of the main raw materials for BOPP color synthetic paper:

1、 Polypropylene resin

Basic material: Polypropylene resin is the basic material of BOPP color synthetic paper, providing the main physical and chemical properties for the paper.

Performance requirements: In order to ensure the high quality of BOPP color synthetic paper, the polypropylene resin used usually has high tensile strength, impact strength, and good transparency.

Type selection: Isotactic polypropylene is often used as the main raw material for BOPP color synthetic paper due to its excellent physical and processing properties.

2、 Functional fillers and additives

Functional fillers: As needed, functional fillers such as pigments and dyes are also added to BOPP color synthetic paper to give the paper specific colors and functional characteristics.

Additives: In order to improve the processing performance of paper and the performance of the final product, antioxidants, lubricants, fluorescent whitening agents, titanium dioxide and other additives are also added.

3、 BOPP film substrate

Definition: BOPP color thermosensitive synthetic paper is a paper made by using BOPP film as the substrate and coating it with a color thermosensitive material containing a thermosensitive agent.

Characteristics: BOPP film has high tensile strength, impact strength, rigidity, toughness, and good transparency, making it an ideal substrate choice.

In summary, the main raw material for BOPP color synthetic paper is polypropylene resin, especially isotactic polypropylene. Functional fillers and various additives are also added to improve its performance and impart specific functions. BOPP film, as a substrate, provides excellent physical properties and chemical stability for paper.
