Publication number: 20100224529Abstract: Heat-shrinkable polyester films comprising a base film having a shrink in each direction of less than 5% at 100° C. and of at least 5% at 150° C. and at least a heat-sealable coating on at least one surface of the base film are disclosed. The film is heat-sealable and peelable in particular to polyester containers. The invention further relates to packages comprising a container, a product and the heat-shrinkable polyester film sealed onto the container. The packages are suitable for use with ready-prepared foods, so-called “ready-meals”, which are intended to be warmed in a microwave or in a conventional oven.Type: ApplicationFiled: July 22, 2008Publication date: September 9, 2010Inventor: Roberto Forloni

Patent number: 7785764Abstract: Provided is an image transfer material, comprising an optional support material, and a non-woven or woven fiber web layer, wherein the fiber web is impregnated or coated with a image receiving formulation. The fiber web layer is optionally attached to the support with an adhesion layer. Also provided is a heat transfer process wherein after imaging, the fiber web and adhesion layer are peeled from the optional support material and placed, preferably image side up (when imaged), on top of a receptor element. Alternatively, the fiber web and adhesion layer are peeled and then optionally imaged prior to being placed on the receptor element. Then, an optional non-stick sheet is placed over the imaged fiber web (if placed imaged side up) and heat is applied to the fiber web or the non-stick sheet, if present. The adhesion layer then melts and adheres the imaged web layer to the receptor element.Type: GrantFiled: February 9, 2005Date of Patent: August 31, 2010Inventor: Scott A. Williams
