Americas: Allpax launches system to protect glass bottles from abrasion in reciprocating retorts

SHARE

After 12 months of research and development, Allpax introduces a new system for lowering the abrasion of sensitive packaging that is sterilized in reciprocating retorts.

This system features compression molded polymer tray liners that are easily installed and replaced on aluminum or stainless steel retort tray bottoms or used as slip sheets between trays.

The polymer liners is an alternative to injection molded trays, costing up to 80% lesser than the latter.

To install and replace the liners, a simple grommet system snaps liner sections onto the tray.

The liners were designed to protect glass bottles with easily abraded metal tops and paperboard retort containers.

The company says aluminum retort trays used in reciprocating retorts are a cost effective solution in the retort room from a life cycle perspective.

These trays last longer than plastic trays and are significantly less expensive than stainless steel trays.

However, aluminum is relatively coarse, which tends to abrade sensitive packaging in reciprocating retorts.

Vulcanized rubber and now the new polymer liners and slip sheets are used to solve this issue.

While the new liners were originally developed for aluminum trays, they can also be used for stainless steel trays if required.
