What are the upstream raw materials for BOPET film? What do the downstream products contain?

BOPET film is a broadly applied in packaging, printing, electronics and other areas of chemical production raw materials. Moreover It has many upstream and downstream related items, and some of the main upstream and downstream items will be described in detail below. Upstream items



1. Dimethyl phthalate(DMT):DMT is one of the main raw materials in the production of BOPET film, which comes from the petrochemical sector. In fact DMT generates dimethyl terephthalate(DMT) through transesterification interaction, and then polycondensation interaction generates polyethylene terephthalate(PET). And

2. Ethylene glycol(EG): Ethylene glycol is another major raw material applied in the production of BOPET film, which also comes from the petrochemical sector. Ethylene glycol reacts with terephthalic acid to form a PET resin. But

3. In my experience, Catalyst: In the manufacturing process, a catalyst is needed to promote the interaction. frequently applied catalysts include magnesium acetate, zinc acetate and the like. Downstream items



1. But In particular Packaging film: BOPET film has excellent mechanical characteristics, high transparency, good barrier characteristics and other characteristics, so it's broadly applied in the packaging sector. it's able to be applied to food, medicine, makeup and other items packaging, as well as electronic items, medical equipment, such as moisture-proof, anti-oxidation protection.

2. Printing film: BOPET film has a smooth surface and good printing performance, so it's often applied in the printing sector. it's able to be applied to make all kinds of printed matter, such as labels, billboards, posters, etc.

3. Insulation material: BOPET film has excellent insulation characteristics, so it is able to be applied to make insulation materials in the electronics sector, such as the insulation layer of wire and cable. Makes sense, right?.

4. I've found that Optical materials: Because BOPET film has high transparency and good optical characteristics, it's able to be applied to make optical materials, such as optical lenses, reflective films, etc. And In short, the upstream and downstream related items of BOPET film are very extensive, involving petrochemical, packaging, printing, electronics and other fields. First With the continuous research of science and methodology, the consumption field of BOPET film will continue to expand.
