The Canadian-owned company made the acquisition of a Hot Glue Rotary labeller from Gernep North America (https://www.gerneplabeling.com) as part of a 5 million dollar project to build a new packaging line capable of packaging a million bottles of Multi-Surface Cleaner & Disinfectant a month. Both the Canadian Federal government and the Ontario Provincial government supported the project since Clorox, Pine-Sol is a DIN registered product and proven to be effective in killing SARS-CoV-2, the virus which causes COVID 19.

A new production line with non-stop labeling
With a multi-year toll manufacturing contract with The Clorox Company to manufacture 12 million bottles of Pine-Sol per year, Dimachem needed to establish a new production line and modify its facility in Windsor to make the product in-house. Numerous pieces of machinery went into the new line. Each would allow them to perform automated tasks from producing their own PET bottles to filling, capping, labeling, case packing and palletizing. 
Among the filling, packaging and labeling solutions Dimachem was considering, they opted for the Gernep Rollina Hot Melt Cut & Stack Rotary Labeler with a cruising speed of 24 bottles/min. Their choice rested on the German equipment because of its flexibility, non-stop labeling, quick changeovers and easy cleanup. Along with unquestionable reliability and ease of use, the support provided through the reputed OEM means guaranteed top quality performance. Mr Conaway, Dimachem‘s Vice President has said as much himself: “The Gernep Cut & Stack Hot Melt Labeler has been one of the best pieces of equipment we purchased for our new line. It has been reliable, well built, and the support has been strong.”
Since implementing the rotary labeler a little over 3 months have passed – enough time to really get into the swing of things. Dimachem has gone from operating its line on one to three shifts. Mixing, bottling and labeling an amazing 1.2 million bottles of Pine-Sol all distributed in Canada.

Hot melt adhesives for labeling
There are various grades of adhesives labeling foods and other consumer goods. Technomelt amber EM 396C hot melt adhesive is a good choice, compatible with glass, pet, polyethylene and pvc. This particular selection provides increased adhesion and a wide operating range – a good fit for their operations.
On a hot-melt cut & stack rotary labeler like Gernep’s Rollina, the initial glue application is  sprayed to the passing container as a series of spiral droplets – variable number according to the label size. A height-adjustable gluing may apply a thin glue film on the end of the label (depending on the application) before applying it to the rotating bottle, achieving a precise overlap.
On this system Gernep integrates Robatech Hot Glue technology due to its specialized applicator and sophisticated electronic control ensuring a perfect glue distribution on any kind of bottle or container, even when operating at maximum speed.
