Most have thought about it, but few know the full answer: why bags with chips They're never full up?
Is there another one? «vagina» is there anything more complex behind this daily question?
The image is familiar. You open a bag of chips with impatience and the first thing you encounter is a gap that looks bigger than you would expect.
The phenomenon has at times caused strong reactions to Social media, with many consumers expressing mistrust towards food companies. However, reality is less «scandalous» and more scientific.
The basic element that explains the phenomenon is the so-called «air cushion», also known as slack fill. But this is not just air.
Bags are mainly filled with nitrogen, an inert gas that plays a crucial role in maintaining product quality. Nitrogen protects chips from moisture And oxidization, two factors that would quickly make them soft and tasteless.
At the same time, it also acts as a natural «shock absorber». When moving from the factory to the supermarket shelf, bags are under pressure, blows, and movement.
If they were full, the chips would reach the consumer shattered. The gap that actually seems excessive is what ensures that the product preserves its form and texture.
But there is also a dimension related to his perception Consumer. The size of the packaging affects the impression of the quantity, even if the net weight is clearly indicated.
Companies know very well the strength of the image and invest in packages that draw the eye. Nevertheless, in many countries there are regulations restricting excessive use «empty» packaging, just to avoid misleading.
It is worth noting that the quantity of «empty» is not arbitrary. It is calculated on the basis of technical and qualitative criteria such as the type of product, its fragility and transport conditions. On more sensitive snacks, this margin is greater.
Therefore the bag that is not loaded up is not necessarily a sign of deception. It is the result of a combination of food technology, logistics and marketing. This does not mean that the consumer should not be careful. The substance is always in the net weight and not in the volume of the packaging.
So maybe next time you open a bag of chips and face the familiar «empty»See it with a different eye. Not as a lack, but as part of a process that ensures that what will reach your plate is as fresh and crisp as possible.
