Plastic cap vs compostable biopolymer cap

Among the various reasons that push consumers to choose one product over another, between habits and needs, there is also the packaging. We can therefore consider it a real strategic choice, both by companies and consumers, and it is for this reason that brands should see it as a fundamental aspect of the marketing mix. 

In the two previous episodes of the packaging challenge, the aluminum tube challenged the glass jar and the plastic tube. While in both cases the challenge was focused on packaging as a whole, today we focus on a single component: the cap. Often we don’t think about it, but the cap plays an important role as it represents the closing and opening door for the fruition of the contents. Moreover, being small and “removable” it is easy to lose it and when you throw it away, even correctly, it does not always end up where it should for the right disposal.   

Most caps, especially the tubes, are made of plastic. But it is not the only possibility! In 2019 Favia launched ToBeNaturAL, a tube that combines the well-known eco-sustainability of aluminum (infinitely 100% recyclable) with a compostable biopolymer cap: a material of natural origin obtained from various sources such as cellulose, pineapple stem or algae, all vegetable sources that give rise to a material that has nothing to envy to traditional plastic in terms of strength, stability and flexibility. 

Attention: not all so-called “bio plastics” are compostable. Only some materials actually degrade as organic waste and it is essential to choose wisely, otherwise you risk to “move” the problem of environmental pollution from one material to another instead of solving it! Here are several good reasons to prefer a compostable biopolymer cap instead of a plastic cap: 

  1. The compostable biopolymer cap from a functional point of view is comparable to the plastic cap: in the hands of those who use it, it is resistant, reliable, safe and easy to clean; 
  1. The compostable cap  has the capacity to degrade completely. Traditional plastic caps, instead, must be recovered and subjected to a recycling process that requires a certain investment in terms of energy; moreover, plastic cannot be 100% recycled like aluminium.   
  1. Companies aiming for sustainable packaging, such as an aluminum tube, must keep in mind that having a plastic cap is the only weak point to achieve complete sustainability. To obtain a 100% smart packaging you have to pay attention to all the details and give up half measures: talking about “recyclable plastic” is not enough, brave choices are necessary, and compostable biopolymers are a real alternative.
