Laser marking on PVA

Ecological bags are an alternative to the global problem of ocean plastic pollution. This kind of initiative stands out in terms of the positive impacts they have on the environment, as well as becoming increasingly present in our daily lives. The rise of these new materials poses the challenge of developing and searching for the best technology to mark and code them in a legible, permanent and sustainable way.

Description

Water soluble bags (PVA) have a unique feature they are transformed into H2O when they decompose. As such they do not generate microplastic waste that is harmful to the environment. This type of bag does not harm marine ecosystems, which makes them a 100% eco-friendly material.

These types of bags are mainly used for bulk purchases, especially in the food sector. Currently, as a result of changing mindsets, trends and legislation, supermarkets are promoting the use of eco-friendly bags with the aim of reducing their environmental footprint, offering consumers ecological and reusable alternatives, in addition to joining the current sustainability trend.

Using Macsa id’s CO2 laser technology, we achieve a high contrast white marking that is perfectly visible and legible. Moreover, through using a power of 30W this process does not damage the material, despite its transparency.
