it may now be common practice in many countries around the world to recycle closures, but it may be even better to use closures for a second time, especially if this can be connected with specific marketing campaigns. they are used first to cap still or carbonated beverages and subsequently to build toys or other artistic shapes. stackcaps can be stacked on top of each other or be assembled side by side by means of grooves. this allows 3dimensional structured toys such as cars, trucks, planes or houses to be built. when combined with the empty pet bottle, toy rockets, space ships, swimming platforms, towers or poles for street games can be constructed. the secondary use of packaging thus also has an educational value in developing handtoeye coordination. sourcewww.bericap.com
