To improve peel strength without using chemical adhesive is a practical advantage. This method plays an important role to enhance peel strength of heat-sealed films. Enhancement was attributed to relaxation of the structure at heat-sealed edge part. Micro-Raman enables evaluation of the mechanical properties of heat-sealed films.
