Abstract:
A system for improving the adhesion of labels to plastic coated bottles including a series of nozzles discretely aligned to disperse a flame over the outer surfaces of a bottle moving on a conveyor. An inline bottle cooling station is also provided comprising an endless porous belt operating in conjunction with a water spray. The bottles are initially spaced apart a predetermined distance on the conveyor, passed by the flame nozzles, and subsequently cooled with a porous belt and water spray assembly.
Abstract:
Articles of glass are coated by applying a first undercoating of an ethylenically unsaturated carboxylic acid which is preferably a polyacrylic acid followed by a coating of a homopolymer of a polyolefin preferably polyethylene. The resulting product has improved durability and resistance to shattering.
