Abstract
Official abstract text for this publication.
Disclosed is a void-containing heat-shrinkable polyester film which is composed of at least two layers, wherein at least one of the layers is a polyester resin layer comprising a cyclic polyolefin resin and containing voids. The film has an apparent specific gravity of less than 1.00 and has specified heat shrinking properties and mechanical properties. Also disclosed is a void-containing heat-shrinkable polyester film as mentioned above, which exhibits specified cuttability along a perforation. Further disclosed is a process for producing a void-containing heat-shrinkable polyester film as mentioned above.
First claim
Opening claim text (preview).
The invention claimed is: 1. A void-containing heat-shrinkable polyester film comprising at least two layers, at least one layer of which is a polyester resin layer containing a cyclic polyolefin resin and a polystyrene resin and having voids, wherein the cyclic polyolefin resin is present in an amount of 5 to 20% by mass based on the entire film weight, wherein a total content of resins incompatible with a polyester resin is 10 to 20% by mass based on the entire film weight,…
