New coatings for HDPE deliver long term barrier solution for solvent-based products

Hangzhou Fancheng Chemical Co.,Ltd | Updated: Jan 19, 2017

A new coating for high density polyethylene (HDPE) containers from RPC Promens Industrial is able to provide a long term barrier solution for solvent-based products for the safer handling of a variety of chemicals.

RPC Protect is available for containers from 5L up to 25L in size. A 30L container is also currently in development.

The special barrier additive, a blend of polyolefins and inorganic silicates, forms multiple strips on the inside of the container. Importantly, unlike other plastic barrier solutions, used containers can be recycled if appropriate.

The availability of RPC Protect enables plastic containers to be selected for an even wider range of products – including extremely hazardous items that previously could only be packed in metal – offering plastics' traditional benefits of lightweight, easy handling and stacking, and reduced transportation costs.

RPC Protect containers have successfully undergone drop, pressure and stacking tests, and their barrier properties have been proven to maintain their performance for up to a year with no reduction in the effectiveness of the barrier, according to the company.

RPC Protect can be specified across the majority of RPC Promens' range of HDPE containers, offering the flexibility to create family ranges with both mono and barrier versions, as well as the option for customized shapes. These containers are approved by US Food & Drug Administration (FDA) and European Economic Community (EEC) for food use. UN certified versions are also available.
