Abstract

Pillow packaging bags made of paper-based materials have been attracting attention from the viewpoint of reducing plastic usage. However, the application of paper materials to the pillow packaging has been limited due to the difficulty in ensuring required quality such as strength, water- and oil-resistance, barrier properties, and printability. In order to have paper pillow packaging used in more fields of applications, we have developed two paper-based packaging materials. One is a highly flexible packaging material that has high puncture strength at the same time. This packaging material is relatively resistant to pinhole formation and is not easily wrinkled during bag manufacturing. The other is a packaging material, in that variable information such as expiration dates, lot numbers, barcode, and QR can be printed with a UV laser. As the information can be printed without direct contact with printheads, printing defects such as faint printouts can be avoided and high quality printing is possible even on paper-based materials where the surface is not smooth. This report introduces the details of these two newly-developed packaging materials.
