**The thermoforming plastics industry has conventionally had closure systems which lock by being assembled at 180 degrees to each other, but how about 90 degrees?**

Macpac’s design engineers asked themselves this question as it demonstrates big potential for furthering and advancing thermoforming technology. 

Over the last few years Macpac has developed a brand new closure which allows packs to be assembled in a completely new way. Macpac and their designers have called it SNAP-IN.The first application was launched in conjunction with Staeger Clear Packaging and it has subsequently offered the perfect solution for one of the UK’s leading supermarket chains. The SNAP-IN innovation delivers the optimal packaging for all sizes of plants and can also provide solutions in the food sector. 

This award winning closure system enables a pack base to be connected to a clear protective sleeve giving rigidity and strength. A series of press stud tabs fold up from the base and snap into die punched holes in the sleeve. Precision manufacture provides a perfect fit making for a strong, robust union between the base and the sleeve. There is a built-in carrying strap handle in the sleeve. It can also be any shape and size. In recent times SNAP-IN won a bronze UK Starpack award.
