Manufacturers face several problems during packaging including:
- Incorrect label information or positioning
- Batch formulation issue including wrong measurement of ingredients, incorrect technique or recipe procedure
- Incorrect product in container
- Requiring one or more parts of the finished product for re-use
- Urgent requirement for volume size not in stock
- Expiry of product and disposal of product
Packserv Australia recommends a few solutions to deal with problems occurring in packaging processes.
The product can be sucked out by reversing the valve positions during the fill cycle to enable the semi-automatic bench top or automated filling machines to draw the product out of the container into a holding vessel.
Caps can be undone for removal by fitting a reversible air motor to a bench top, automated capper or pumptite unit.
Tables can be converted to rotate anti-clockwise while conveyors can be reversed to travel upstream.
Over-labelling using orientation is achieved by fitting a sensor to semi-automatic bench top or automated labellers. The sensor picks up the eye-mark on the container as it passes by and applies the new label in the desired location.
Packserv Australia also advises manufacturers to check with their industry body or waste service on packaged product disposal requirements including recycling. Manufacturers may be required to dispose of their products in a manner that disables the product from being re-sold.
