Balloons
Whether for birth, school enrolment, passed exam or wedding - there is almost no occasion for which plastic balloons are not given away. They come in almost every shape and colour. If they fly away and the helium escapes, the red heart also becomes marine waste.

To increase the durability and to keep the gas permeability as low as possible, two polyethylene foils are usually welded together for these balloons. Aluminium is then evaporated onto the outer layer, which serves as the basis for a wide variety of colour combinations.
