The problem of stress whitening in RCP is solved by Belgium

In the production of rigid packaging, polypropylene materials are often used to provide stiffness and heat resistan.

As a leading food container manufacturer in China, how does Ningbo Lishi Commodity .

In daily operations, Belize mainly uses random copolymer polypropylene (RCP) for the production of food containe.

However, as production progressed, Belize found that the impact strength of RCP was mediocre, especially at low temperatur.

In response to this phenomenon, Lithium used an industry standard thickness of 3 to 6 mm to produce hinges in the production process, and tried to modify RCP with ordinary PP toughening agen.

In a dilemma, Belgium turned to ExxonMobil's application and technical exper.

Durable and more assured

Freeze testing in Belize shows that after modifying RCP with a small amount of Vistamaxx, the impact strength of the container lid is enhanced, even in the temperature range as low as 0°C to minus 20°C, and it is not easy to bre.

Meanwhile, Belgian testing also showed Vistamaxx could improve the durability of container lid hinges by improving their flexibili.

The appearance is more comfortable

Of all the additive materials tested by Belize, only Vistamaxx performance polymers were able to maintain excellent transparency while improving the impact strength of lid hinges in freezer testing, while effectively reducing stress The problem of whiteness greatly enhances the aesthetics of the produ.

Easier to comply with regulations

Vistamaxx polymers comply with various international food contact regulations, including the US FDA, EU and JHOS.
