The Liqui-tec Hem Pre-Seal Section LT-HPS


The Liqui-tec LT-HPScan be retrofitted to any existing flame sealer including all IPBM LA, LF and LF-B machines. They are available in either a left hand or right hand configuration. Left hand is for spout first fed cartons and right hand is for bottom first fed cartons. The most common is right hand, bottom feed.

The section consists of five critical components; the Skiver, the Hem Creaser, The hot air Impingement Burner, the Vacuum Hemmer and the Hem Crusher unit. This system has been expertly designed from over 50 years of in field experience.

The LT-HPS uses the patented Liqui-tec Vacuum Hemmer process. The Liqui-tec Pre-Seal Section is a machine with a proven track record of higher speeds and exceptional skiving and hemming quality.

The section is designed to be a drop in conversion in between the prefold and the burner section and is designed to be utilized on belt driven machines. Optional line shaft conversions kits will allow it to be installed on Gear driven machines as well.
