Title:
HEAT-SHRINKABLE FILM AND HEAT-SHRINKABLE LABEL
Document Type and Number:
WIPO Patent Application WO/2013/011826
Kind Code:
A1
Abstract:
Provided are a heat-shrinkable film having superior abrasion resistance and a heat-shrinkable label using the film. The heat-shrinkable film is characterized in being obtained by coating a film substrate formed from a polyester resin or polystyrene resin using an aqueous coating material formed from an emulsion (A), which comprises a polymer of an ethylenic unsaturated monomer the protective colloid of which is a water-soluble polyester or water-dispersible polyester, and a wax lubricant (B). Preferably the wax lubricant (B) is a polyethylene wax or polyproylene wax and has a melting point between 90 and 160ºC.
