Muller Launches New In-Mold Labeling (IML) Automation System for 5-Gal Pails

Published: April 27, 2021

Muller Technology, a global leader in tool making and automation technology for thin-wall plastic packaging, has launched an innovative in-mold labeling (IML) automation system for the production of 5-gallon pails that reduces cost, improves productivity, and enhances graphics and product appearance.

Muller’s new IML system reportedly offers major improvements over standard pressure-sensitive and printed systems which are time-consuming and require double handling of parts. 

“Our IML technology enables pail manufacturers to add to their product offering without any infrastructure changes, enabling them to maintain a small footprint and limiting costly scrap,” said Taras Konowal, director of sales and marketing, North America, Muller.

Muller responded to customer needs with a one-piece IML system which is less than 8-foot wide compared to competitive IML systems that are 12-14 feet wide. It fits conveniently into non-IML production lines, requires no adjustment in floor layout, and fits any injection molding machine height.

The IML system places the wrap-around polypropylene (PP) label into the mold, removes the pail after molding, and transports it to a visual inspection station. The pail is then directed to stacking and handle assembly. Systems could be easily converted from 1-cavity to two-cavity to enable the production of 1- to 5-gallon pails. 

Manufacturers often face the costly scrapping of a finished pail due to label misalignment. A key feature of Muller’s IML system is digital label placement positioning which reportedly provides significant precision and detailed label placement versus standard, manually adjusted magazines.

The system also has quick changeout capability from pail size to pail size and label to label. Rotating dummy mandrels allow label seams in different locations.
