BESCHREIBUNGDESCRIPTION
Die Erfindung betrifft eine durchsichtige Kunststofffolie für Verpackungszwecke o. dgl.The invention relates to a transparent plastic film for packaging purposes or the like
Bei der Verpackung namentlich auch von Lebensmitteln kommt es entscheidend darauf an, das Verpackungsgut durch die Verpackungsfolie hindurch einwandfrei erkennen zu können. Wegen seiner hervorragenden Durchsichtigkeit wird daher in der Praxis regelmäßig Zellglas, eine Folie auf Viskosebasis, eingesetzt.When it comes to the packaging of food, in particular, it is crucial on recognizing the packaged goods perfectly through the packaging film to be able to. Because of its excellent transparency, it is therefore used in practice Cell glass, a viscose-based film, is regularly used.
Diese ist jedoch wegen ihres vor allem aus Festigkeitsgründen benötigten hohen Flächengewichts (ca. 36g/m2) entsprechend teuer.However, this is required because of its strength, especially for reasons of strength high grammage (approx. 36g / m2) correspondingly expensive.
Polyäthylen-Folien haben sich für die Verpackung solcher Güter, auf deren klare Erkennbarkeit im verpackten Zustand es ankommt, nicht einführen können. Folien aus Hochdruck-Polyäthylen sind zwar relativ gut durchsichtig, aber vor allem aus Kostengründen ungeeignet. Folien aus Niederdruckäthylen, die sich in sehr geringen Dicken ausreichend reißfest herst-llen ließen, sind hingegen nicht durchsichtig, sonden nur matt durchscheinend und schieden daher bislang ebenfalls für die oben erwähnten Verpackungszwecke aus.Polyethylene films have been used for packaging such goods whose clear recognizability in the packaged state is important, cannot introduce. Films made from high-pressure polyethylene are relatively transparent, but above all unsuitable for cost reasons. Films made of low pressure ethylene, which are in very low Thicknesses made sufficiently tear-resistant, however, are not transparent, probes only matt translucent and have therefore also been used for the above so far mentioned packaging purposes.
Es wurde nun gefunden, daß eine Niederdruck-Polyäthylen-Folie die gewünschte Durchsichtigkeit erhält, wenn man sie mit einem Lack behandelt. Als geeignet hat sich ein glasklarer Lack auf Nitrozellulosebasis (Nagellack) erwiesen, was jedoch nicht andere Lacktypen als ebenfalls geeignet ausschließt.It has now been found that a low-pressure polyethylene film the the desired transparency is obtained if it is treated with a varnish. As suitable a crystal clear lacquer based on nitrocellulose (nail polish) has proven, but what does not exclude other types of paint as also suitable.
Vorzugsweise wird die Niederdruck-Polyäthylen-Folie, die insbesondere eine Dicke von nur etwa 0,01 mm bei einem Flächengewicht von ca. lOg/m2 hat, beidseitig mit dem Lack behandelt und auf diese Weise im allgemeinen durchtränkt,Preferably, the low-pressure polyethylene film, in particular has a thickness of only about 0.01 mm with a weight per unit area of about 10 g / m2, on both sides treated with the varnish and generally soaked in this way,
