Abstract

To address plastic pollution and bottlenecks of existing packaging materials and respond to the "replace plastic with paper" strategy, the work aims to develop a hydrophobic cellulose transparent film and integrally prepare a degradable laser holographic film via synergistic optimization of fiber structure, photocuring system and molding process. With bleached eucalyptus kraft pulp (BEKP) as the substrate, base paper was fabricated with optimized PFI beating (15 000 revolutions, beating degree 30°R-40°R). A composite photocuring system of 2-ethylhexyl acrylate (EHA), 1,6-hexanediol diacrylate (HDDA) and acrylated epoxidized soybean oil (AESO) was adopted. The transparent film showed excellent performance of transparency 88.9%, haze 18.4%, maximum tensile strength 53.1 MPa, water contact angle 105.8°, theoretical bio-based content 72%, and 60.2% degradation rate after 80-day soil burial. By increasing impregnating solution retention and replacing release films with recyclable PET aluminum-coated films, conformal transfer of aluminum layer and microstructures was realized. The degradable laser holographic film is successfully applied to cigarette packaging, overcoming core drawbacks of traditional laser transfer paper (color cracking, peeling, insufficient barrier property) with simplified process and lower energy consumption, showing broad prospects in green tobacco/alcohol and anti-counterfeiting packaging.
