Abstract

The cushioning consists of vegetable pith, made e.g. from sunflower, which is made friable in the form of cylindrical bodies. The length of these bodies is 30-30 mm. The pith may be made into blocks or shaped packs by gluing the bodies together with a waterproof glue.This material can also be formed into rolls of packing material with a cushioning capability. Graphs showing the results of studies of the impact strength and pressure resistance are included.

Description

Die Erfindung betrifft ein Polstermittel zum Arretieren und Polstern von Packgütern, das biologisch abbaubar ist und aus nachwachsenden Rohstoffen hergestellt wird.The invention relates to a cushioning means for locking and Padding of packaged goods that is biodegradable and made of renewable raw materials is produced.

Nach WO 92/0425 ist ein biologisch abbaubares Verpackungsmaterial bekannt. Das Verpackungsmittel wird aus durch Hitze aufgepoptem Mais oder Getreide hergestellt und mittels organischem Binder in eine feste Form gebracht.According to WO 92/0425 is a biodegradable packaging material known. The packaging material is made of heat puffed up Maize or grain produced and in organic binder brought a solid form.

Nachteilig ist, daß sich Popcorn im Wasser auflöst bzw. bei Wassereinfluß die gepopte Form verliert.The disadvantage is that popcorn dissolves in the water or at Influence of water loses the populated form.

Es ist weiterhin bekannt, geschäumte Stärke (z. B. Renatur) als Verpackungsmittel zu verwenden. Nachteilig ist ebenfalls dessen Wasserlöslichkeit.It is also known to be foamed starch (e.g. Renatur) Use packaging. This is also disadvantageous Solubility in water.

Aufgabe der Erfindung ist es, ein biologisch abbaubares Verpackungsmittel anzugeben, das auf Basis nachwachsender Rohstoffe herstellbar ist und beständig gegen Wasser- oder Feuchteeinwirkung ist.The object of the invention is a biodegradable Specify packaging that is based on renewable raw materials is producible and resistant to the effects of water or moisture is.

Die Erfindung wird mit den in den Ansprüchen genannten und im Ausführungsbeispiel näher erläuterten Mitteln gelöst.The invention is with those mentioned in the claims and in Exemplary embodiment solved means solved.

Es wurde gefunden, daß das Mark der Sonnenblume zur Verarbeitung zum Polstermittel für Verpackungszwecke gut geeignet ist. Das Mark weist ein besseres Stoßabsorptionsvermögen und bessere Dämpfungseigenschaften als Popcorn und Renatur auf.It has been found that the marrow of the sunflower is for processing is well suited for upholstery for packaging purposes. The mark has better shock absorption and better Damping properties as popcorn and renatur.

Das Mark läßt sich durch Schälen und Zerkleinern aus den Pflanzenstengeln gewinnen und ohne zusätzlichen Wärmeeintrag, wie er z. B. bei der Herstellung von Popcorn oder beim Aufschäumen der Stärkeschaumprodukte nötig ist, zu Polstermittel verarbeiten. Die Pflanzenstengel bleiben als Rest übrig. The pulp can be removed by peeling and chopping Plant stems gain and without additional heat input, such as he z. B. in the production of popcorn or foaming Starch foam products is necessary to process upholstery. The Plant stems remain as the rest.  

Eine weitere vorteilhafte Eigenschaft gegenüber Popcorn und aus geschäumter Stärke hergestellten Produkten besteht in der Unlöslichkeit des Marks für Wasser. Das Pflanzenmark läßt sich daher mittels wasserhaltigem Kleber zu Blöcken oder Formteilen verarbeiten.Another beneficial property over and out of popcorn foamed starch products consists in the Insolubility of the pulp for water. The vegetable pulp can be therefore using water-based glue to form blocks or molded parts to process.

Durch Beflocken einer Packstoffbahn mit schüttbarem Polstermaterial und Kaschieren durch eine weitere Packstoffbahn sind bahnförmige Packstoffe mit entsprechender Polsterwirkung herstellbar.By flocking a packaging material web with pourable padding material and lamination by another packaging material web are web-shaped Packaging materials with a corresponding cushioning effect can be produced.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. In der Zeichnung zeigenThe invention will be explained in more detail using an exemplary embodiment are explained. Show in the drawing

Fig. 1 ein Diagramm mit Darstellung der Stoßstärke als Funktion der statischen Flächenlast Fig. 1 is a diagram showing the impact strength as a function of the static surface load

Fig. 2 ein Diagramm mit Darstellung des Stauchdrucks als Funktion der Stauchung in %. Fig. 2 is a diagram showing the compression pressure as a function of the compression in%.

Die Stengel der Sonnenblume wurden geschält und das Mark zu zylinderförmigem Granulat mit einer Länge von etwa 23 mm verarbeitet. Das Granulat wurde mit Latex ohne Einwirkung von Druck zu einem Block verklebt. Der Block hatte die Abmaße (95² × 49) mm³ und durch den Kleber das 5fache Gewicht des Ausgangsmaterials. Die Dichte betrugt 81,4 kg/m³.The stems of the sunflower were peeled and the marrow closed cylindrical granules with a length of about 23 mm processed. The granules were covered with latex without pressure glued to a block. The block had the dimensions (95² × 49) mm³ and 5 times the weight of the starting material due to the adhesive. The Density was 81.4 kg / m³.

In Fig. 1 ist die Stoßstärke als Funktion der statischen Flächenlast aufgetragen. Das für zwei Punkte ermittelte Stoßabsorptionsvermögen vom Sonnenblumenmark 1 ist mit Popcorn 2 und Renatur 3 absolut vergleichbar, erstreckt sich aber nach dem vermuteten Kurvenverlauf zu urteilen, über einen größeren Bereich. Damit ergeben sich Vereinfachungen bei der Dimensionierung des Verpackungspolsters.In Fig. 1 the impact strength is plotted as a function of the static surface load. The shock absorption capacity of sunflower marrow 1 determined for two points is absolutely comparable with popcorn 2 and renatur 3 , but, judging from the suspected curve, extends over a larger area. This simplifies the dimensioning of the packaging cushion.

In Fig. 2 ist der Stauchdruck als Funktion der Stauchung in Prozent für feuchtes Material dargestellt. Die Differenz zwischen den Kurven der Belastung a und der Entlastung b läßt auf gute Dämpfungseigenschaften des Materials schließen, da die Federkonstante und damit die Eigenfrequenz des Gut-Polster-Systems für Be- und Entlastung verschieden ist. Die Untersuchungen der Wasseraufnahme und -beständigkeit ergab weiterhin, daß das Material in der Lage ist, Wasser mit einem Gewicht von bis zum 10fachen seines Eigengewichtes aufzunehmen.In Fig. 2 the compression pressure as a function of the compression percentage for moist material. The difference between the curves of the load a and the relief b suggests good damping properties of the material, since the spring constant and thus the natural frequency of the good cushion system for loading and unloading are different. The studies of water absorption and water resistance also showed that the material is able to absorb water with a weight of up to 10 times its own weight.

Das Material brennt im trockenen Zustand nach Entfernen der Zündflamme nicht weiter, sondern glimmt nur. Stärkeschäume brennen mit offener Flamme, Schaumpolystyrol kann mittels physiologisch und ökologisch bedenklicher Substanzen flammhemmend ausgerüstet werden. Das Material erfüllt die Forderungen der Brandklasse 1 nach DIN 53 438.The material burns when dry after removing the The pilot flame does not continue, it just glows. Starch foams burn With an open flame, foam polystyrene can be physiologically and by means of ecologically questionable substances are flame retardant. The material meets the requirements of fire class 1 DIN 53 438.
