An adhesively laminated bite plastic film comprising at least two layers of preformed plastic film adhered together by means of an adhesive material disposed therebetween but having preselected areas which contain neither the adhesive nor anything else which is incompatible with said plastic is disposed between the layers of plastic film or on the surfaces thereof. The cite is quite usable for forming into plastic bags by either folding the composite film upon itself and heat sealing the meeting edges, or by superposing the composite film with at least one other plastic film, which may itself be a bite film, and then heat sealing the meeting edges. The preselected areas which are devoid of adhesive correspond to the heat seal areas.
