  • Label for removable attachment to an article
    Patent number: 9005742
    Abstract: A label for removable application to an article such as a beverage bottle includes a backing layer (2) comprising a laminate of a bi-axially oriented polyester such as PET (12) and a bi-axially oriented polypropylene (14). The polyester film (12) has a lower coefficient of thermal expansion than the polypropylene film (14). Consequently, when the label is heated, it will tend to curl and this effect can be used to assist in the removal of the label from the article in a hot washing bath during recycling of the article.
