Hot fill for PET: economy and appeal

Following an analysis of the ketchup and sauce containers currently available on the market, P.E.T. Engineering is offering an alternative to HDPE and PP containers (heavy and costly to produce), as well as PET containers (difficult to customize due to their inevitable rigid structure), for hot fill packaging.

In order to withstand filling processes at up to 85° without losing their shape, PET containers can weigh as much as 30 g and have rigid panels on both sides that make it difficult to create distinctive and appealing designs.
P.E.T. Engineering’s team of engineers and researchers therefore approached the project from a different perspective, starting from the material with which the container is made and not the design. The team made use of the concern’s new preform prototyping service to test various materials for the hot fill process, identifying the most suitable one.

The preform design, combined with the material and planning of the container, has enabled the concern to create a packaging solution that weighs just 25.5 g and can carry 400 g of sauce. The new container is produced through standard blowing, and has a Bericap 38 neck with aluminium foil, also standard (not solid aluminium, as in conventional hot fill containers).
Put briefly: lowered production and transport costs, but also greater customization options for a container that is set to revolutionize hot fill for PET containers.
