BOPP (biaxially oriented polypropylene) is a widely used chemical raw material, mainly used in packaging, printing, tape, labels and other fields. Its upstream and downstream related products are numerous, and some of the main products are described in detail below.

upstream related products:

1. Polypropylene (PP): The main raw material of BOPP is polypropylene. Polypropylene is a thermoplastic resin polymerized from propylene monomer. It has excellent chemical resistance, heat resistance, Electrical insulation and mechanical properties.
2. Catalyst: The production of polypropylene requires the use of a catalyst, such as a Ziegler-Natta catalyst or a metallocene catalyst, to promote the polymerization of propylene monomer.
3. Additives: In order to improve the performance of BOPP, some additives may be added during the production process, such as antioxidants, anti-ultraviolet agents, slip agents, etc.

Downstream Related Products:

1. Packaging Film: BOPP can be used to produce various packaging films, such as food packaging films, pharmaceutical packaging films, industrial packaging films, etc., with excellent transparency, barrier properties and mechanical strength.
2. Printing film: BOPP printing film is widely used in various printed materials, such as trademarks, labels, advertisements, etc., with good printability and abrasion resistance.
3. Tape: BOPP can be used as a substrate to produce various tapes, such as sealing tape, double-sided tape, etc., with strong adhesion and good weather resistance.
4. capacitor film: BOPP capacitor film has high insulation, high heat resistance, high moisture resistance and other characteristics, widely used in the field of electronic power capacitors.

In short, BOPP has many upstream and downstream related products, involving various fields, such as packaging, printing, electronics, etc. Understanding these related products helps to better understand the application and market situation of BOPP.
