Abstract
The invention relates to a method of packaging an adhesive composition, especially a thermoplastic or thermosetting hot melt adhesive. The method comprises the steps of providing one substantially uniform separate portion of the adhesive composition; sufficiently solidifying said portion for packaging; substantially completely surrounding said sufficiently solidified portion with a plastics packaging material. The packaging material being meltable together with the adhesive composition and blendable into said molten adhesive composition, the kind and amount of said packaging material being chosen so as not to disadvantageously affect the properties of the adhesive composition when blended into same. Preferably, the packaging material is a net, a wrap, a sack or a bag. Packagings made of plastic film are advantageously voided of air, to prevent problems in melting. The packaged adhesive can be melted as it is.
