AB  - Thermoplastic films exhibit good potential to be used as adhesives for the 
      production of veneer-based composites. This work presents the first effort to 
      develop and evaluate composites based on alder veneers and high-density 
      polyethylene (HDPE) film. The effects of hot-pressing temperature (140, 160, and 
      180  degrees C), hot-pressing pressure (0.8, 1.2, and 1.6 MPa), hot-pressing time (1, 2, 
      3, and 5 min), and type of adhesives on the physical and mechanical properties of 
      alder plywood panels were investigated. The effects of these variables on the 
      core-layer temperature during the hot pressing of multiplywood panels using 
      various adhesives were also studied. Three types of adhesives were used: 
      urea-formaldehyde (UF), phenol-formaldehyde (PF), and HDPE film. UF and PF 
      adhesives were used for the comparison. The findings of this work indicate that 
      formaldehyde-free HDPE film adhesive gave values of mechanical properties of 
      alder plywood panels that are comparable to those obtained with traditional UF 
      and PF adhesives, even though the adhesive dosage and pressing pressure were 
      lower than when UF and PF adhesives were used. The obtained bonding strength 
      values of HDPE-bonded alder plywood panels ranged from 0.74 to 2.38 MPa and met 
      the European Standard EN 314-2 for Class 1 plywood. The optimum conditions for 
      the bonding of HDPE plywood were 160  degrees C, 0.8 MPa, and 3 min.
