Nonoriented stiff packaging film with superior tear properties

   
   

A nonoriented film containing highly crystalline polypropylene, standard polypropylene and nucleating agents. The film has physical properties that are desirable for applications such as food wrappers and tampon overwrap, including good tearability, stiffness and memory. In addition, the nonoriented film is cost effective because the film achieves these physical properties without the step of stretching or orienting the film, as required for conventional polypropylene films used in food wrappers and tampon overwrap.

A nonoriented le film contenant le polypropylène fortement cristallin, polypropylène standard et nucleating des agents. Le film a les propriétés physiques qui sont souhaitables pour des applications telles que les emballages de nourriture et la surenveloppe de tampon, y compris le bons tearability, rigidité et mémoire. En outre, nonoriented le film est rentable parce que le film réalise ces propriétés physiques sans étape d'étirer ou d'orienter le film, comme requis pour les films conventionnels de polypropylène utilisés dans les emballages de nourriture et la surenveloppe de tampon.
