Injection Molding PPR MT45 for Lunch Boxes

PPR MT45 is a high melt index transparent polypropylene product developed. It is a random copolymer polypropylene.

The material refers to a specific type of polypropylene (PP) produced by SINOPEC, which is one of the largest petroleum and petrochemical companies in China. PPR MT45 is a grade of polypropylene resin.

High melt index transparent polypropylene has excellent transparency, gloss and good fluidity, and is widely used in the processing and production of large or deep cavity thin-walled containers, such as finishing boxes, microwave supplies, cups, lunch boxes and syringes, etc. Compared with traditional Medium and low melt index polypropylene, with good processability, can greatly reduce energy consumption and improve production efficiency.

The material has the characteristics of beautiful appearance, high transparency and good gloss.

The material offers the highest mechanical properties among the PPR MT series, including higher stiffness, greater impact resistance, and better resistance to stress cracking. It also has excellent chemical resistance, even at high temperatures, making it suitable for applications that require contact with chemicals or hot liquids.
