Abstract
An improved release system for heat transferable laminates wherein a transferable substrate which contains a design layer is transferred from a carrier web onto an article such as a plastic bottle or container upon application of heat and pressure. The carrier web includes a nonwax polyethylene layer. The improved release system includes a polyethylene layer portion of the carrier web in contact with and adhered to a nonwax transfer layer portion of the transferable substrate. The transferable substrate including the ink design layer transfers to the article upon application of heat to the carrier while the article contacts the laminate. The transferred substrate on the article is clear and exhibits improved scuff and abrasion resistance. The nonwax transfer layer portion of the transferable substrate advantageously contains an oil which becomes activated upon application of heat to promote release of the transferable substrate from the carrier web to the article.
