40+ years of foam extrusion innovation
Since opening in 1983, Alcot Plastics has built its reputation on a simple idea: innovation does not have to be complicated. Founder Jan Alac developed a smarter, faster extrusion process from the ground up, and that same approach drives the company today, with his son John now helping lead it. From its early roots in Milton, Ontario to its current Guelph facility, Alcot has grown alongside its customers while keeping the same hands-on, flexible way of working.
Canadian manufacturing with a practical focus on waste reduction
Alcot manufactures in Guelph, Ontario and recycles the polyethylene foam production scrap generated through its extrusion process. Keeping recoverable material in circulation helps reduce disposal while supporting responsive, Canada-based production.
