Laser marking on PVA

02/07/2021

Macsa ID laser equipment is used to encode and mark products of a wide variety of materials, including paper, cardboard, plastics (PET, PVC, HDPE), glass, metals and wood. The messages and graphics that are achieved are of high quality, at a minimum operating cost and at high speeds.
Application News regularly provides a sample of products that are encoded and labelled with Macsa ID lasers, every day and worldwide.

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.

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.

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 sustainablity 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.
