Abstract
A recyclable film contains a base film of polyethylene that has been oriented, annealed, and irradiatively crosslinked, and a sealant. The base film has a free shrink rate of less than 10% in both the machine direction and the transverse direction when exposed to heat of 90° C. These recyclable films are ideal for use as packaging components that can be hermetically heat sealed to themselves or other packaging components, while maintaining low shrink and excellent appearance.
