摘要 |
<p>A polymeric composition suitable for manufacturing heat sealable films or sheets comprising, polyethylene terephthalate (PET) to the extent of about 80 % to 95 % by mass of the total composition; a polymer additive for lowering the melting point of the composition selected from Polyethylene Naphthalate (PEN), Polytrimethylene Naphthalate (PTN), in-situ formed Polyethylene Naphthalate (PEN) and in situ formed Polytrimethylene Naphthalate (PTN) to the extent of about 20 % to 5 % by mass of the total composition; a nucleating agent to the extent of about 200 to 1500 ppm by mass of the composition; a polycondensation catalyst to the extent of about 30 to 300 ppm by mass of the composition; a clear fast reheat (CFRH) additive to the extent of about 10 to 30 ppm by mass of the composition; a color toner to the extent of about 0.75 to 25 ppm by mass of the composition; and a heat stabilizer to the extent of about 20 to 55 ppm by mass of the composition.</p> |
