Styrofoam and high-density foam inserts are an essential component of a packaging solution when fragile products such as bottles, glasses, candles, medical equipment, etc. need to be safely placed. The foam used for packaging is different from the usual one, because it is more dense, less dense and much more beautiful. Cardboard inserts are a simpler and cheaper solution when the products are not so fragile, but you want the product(s) to stay in the intended place. When designing box liners, efforts are made to make removing the product from the package convenient and easy.
