%X Currently, due to scarcity of hydrocarbon resources
and the extensive use of water based, solvent based and hot melt adhesives in
wood bonding in furni<span><span><span style=\"font-family:;\" \"=\"\">ture industries and packaging industries that demand
recyclability, compostability and bio-degradability, recent</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">ly</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> attention
ha</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">s</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> been concentrated to <span>making these
formulations completely bio-based, sustainable and b</span>iodegrad<span>able. Biodegradable hot melt adhesives (HMAs)
prepared from natural sources</span> have a potential for use in furniture and
packaging industries<b> </b>because of an i<span>ncrease
in awareness of environmental issues, the replacement of co</span>nven<span>tional petroleum-derived hydrocarbon raw materials
by renewable, biodegradable a</span>nd sustainable materials has developed. In
terms of environmental issues, such as climate crisis due to an increase of
carbon dioxide emission, at<span>tempts have been
made to produce HMAs using non-hydrocarbon resins, such</span> as polylactic
acid (PLA)-based resins, containing no petroleum as a raw ma<span>terial. Polylactic acid was prepared by
self-condensation reactions of lactic acid </span>or by lactide ring opening
polymerisation, and used for packaging materials, <span>sanitary pads, diapers etc</span></span></span></span><span><span><span style=\"font-family:;\" \"=\"\">.</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">, especially adhesives owing to its excellent
processability</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> and the excellent mechanical properties of its HMAs
products. <span>There</span>fore, recently the use
of PLA materials as a substitute for non-biodegradable hydrocarbon-</span></span></span><span><span><span style=\"font-family:;\" \"=\"\">based
polymers can be considered to be environmentally favourable. Here, we discussed
the various uses of PLA as a sustainable and bio-degradable and sustainable hot
melt adhesive.</span></span></span>
