Food packaging manufacturers need to select suitable materials for packaging to provide stability throughout various processes and storage. This is particularly important in retort packaging which will expose the food product to heat to ensure food safety and long shelf life.

Retortable CPP Film (RCPP) can be used in instances where heat resistance and good sealing characteristics are required. Due to its compatibility with multi-layer flexible packaging systems, it can be an important choice for some ready to eat meals, processed foods and retort packaged items.

Manufacturers should consider the heat resistance, sealing strength, barrier requirements, laminating ability and retort process conditions. For further technical details on Retortable CPP Film (RCPP), please click here.
