Abstract
Recyclable and dimensionally stable films for packaging include an oriented base film having a first layer containing a polar polymer and a second layer containing a stabilizing polyolefin, wherein the stabilizing polyolefin is selected from the group of an ethylene/norbornene copolymer having a norbornene content greater than 20 mol %, a polyethylene polymer having a density greater than 0.94 g/cm3, and a polypropylene homopolymer.
Claims14
A recyclable film comprising:
- a) an oriented base film comprising:
- i) a first layer comprising a first polar polymer,
- ii) a second layer comprising a stabilizing polyolefin comprising a refractive index between 1.526 and 1.542, and
- iii) a third layer comprising a second polar polymer,
- b) a sealing layer, and
- c) printed indicia located on one of the major surfaces of the oriented base film, and wherein the oriented base film has a free shrink value of less than 5% in both the machine direction and the transverse direction when tested according to ASTM D2732 using bath temperature of 90° C.
