Freeze resistance is a newly demanded functional indicator for paper applied in alpine areas, frozen food packaging and outdoor logistics. Under sub-zero freezing environment, internal bound water of paper fibers will condense into tiny ice crystals, which destroy fiber bonding points, crack fiber structure, make paper brittle, fragile and easy to break under slight folding or extrusion. Ordinary paper will lose more than half strength after freezing, unable to support carton stacking, label pasting and commodity outer packaging in winter low-temperature environment. Northern regional logistics enterprises always face high packaging paper scrap rate in winter, and traditional toughening agents cannot resist structural damage caused by ice crystal expansion. Shandong Ludao Energy Technology Co., Ltd. develops professional paper freeze-resistant modification solutions. By adjusting fiber bound water activity, inhibiting ice crystal formation inside paper, and building flexible buffer bonding structure between fibers, we protect fiber integrity under freezing temperature. The treated paper maintains stable toughness, folding performance and tensile strength in sub-zero environment, will not crack or pulverize, fits winter outdoor logistics, frozen food packaging and alpine industrial packaging usage, and creates seasonal competitive advantages for paper manufacturers.
