摘要 |
The present invention relates to a bi-oriented polypropylene film comprising a polypropylene homopolymer base layer and at least one adjacent heat sealable polymeric layer, which in turn is constituted of a hydrocarbonic resin and a polymeric material. This film is used for making packages for paper reams, foods-tuffs, perfumery among other packages, since it exhibits ideal properties to ensure adequate closure and airtightness thereof. Thus, it protects the packed product against the action, for example, of moisture and dust. |
