Enhanced oxygen transmission - Microperforation by laser of plastic films for fresh produce packaging
Researchers at the National Science and Technology Development Agency in Thailand perforated three different plastic films using laser: BOPP, BOPET and LDPE. They found that perforation diameters of all films increased with increasing pulse energies. Observed perforations were different among the three film types. Explanation was contributed to material inherent property and its interaction with laser.
Overall results clearly indicated that perforation by laser is an effective process in developing breathable films with tailored oxygen transmission property for fresh produce packaging. An article about the research is published in Packaging Technology and Science.
