ODOUR CONTROL PROPERTIES
Abstract A film for use in the construction of food or garbage bags is described which contains from 0.001 to 0.1 weight percent of methyl-(2-amyl-3-oxocyclopentyl)-acetate as an odour modifying agent.
Description
~l:255~3g 'rhis invention rela-tes to a thermoplas-tic ~ilm having an odour modifying agen-t incorporated therein. More particularly it relates to a bag suitable for the storage of garbage or other malodorous material which is made of thermoplastic film having an odour modi~ying ayent blended therein.
In order to reduce undesirable odours from the stored contents in plastic garbage bags or kitchen bags attempts have been made in the past to incorporate a perfume into the plastic so that the fragrance of the perfume will dominate the garbage odours. In order to accomplish this, the fragrance must be so strong and dominant that the perfume overwhelms the storage area. In the case of a kitchen bag in particular, the strong perfume can be cloying to the consumer.
Also the perfume dissipates through the house and may interfere wi~h Iood taste and flavourings.
The applicant discovered that garbage bag odours can De considerably reduced if the garbage bag film has a certain odour modifying agent incorporatea therein within the weight percent disclosed below. The odour modifying agent found most suitable ~or this purpose is methyl-(2-amyl-3-oxocyclopentyl)-acetate sold by Firmenich Incorporated of Princeton, N. J. This can be represented by the chemical formula;
C ' H..C CH--(CH.),CH, H~C----CH--CH,--COO -CH3 .
This is a pale yellowish or almost colourless oily liquid which is slightly soluble in water and has a slight jasmine-like odour. It is generally used in the fragrance art as an additive to cosmetics and toilet articles .
~25583~3 o subdue the sharp odour of certain ingredients or enhance the odour of fragrances.
The applican-t has discovered that this odour modifying agent in an amount of from .001 to O.l weight percent in the thermoplas-tic material can provide effeetive suppression of garbage odour when such thermoplastic material is extruded into film and made into garbage bags without adding a jasmine or other additional odour to the bag.
Because oE the cost factor however the preferred range of the odour modifying agent is from .001 to 0.05 weight pereent in the thermoplastic material.
It is therefore an object of this invention to provide a film comprising thermoplastic material having blended therein from 0.001 to 0.1 weight percent of methyl-(2-amyl-3-oxocyclopentyl)-acetate per weight of said thermo-plastic material.
It is another object of this invention to provide a plastic garbage bag of there plastic film wherein said film includes from 0.001 to 0.1 weight percent of methyl-(2-amyl-3-oxocyclopentyl)-acetate.
While the odour modifying agent in the amount specified above provides the desired odour suppressant characteristics ~ithout adding an interfering fragrance of its own, it might be found advantageous from a purely marketing point of view to include another fragrance in the film at least to inform the customer that a desirable additive has been included in the film or garbage bag.
This can be any fragrance that is compatible with the kitchen environment such as a musk or floral scent. This fragrance should not be more than 0.5~ by weight of the thermoplastic material as its odour above these eoncentrations might be considered obnoxious in the kitchen. This is . ' ' .

~lowever, at least 0.001 weight percent is needed to provide a trace of fragrance when ~he film is inspec-ted at close ranye. It was found tha-t the most preferred concentration of fragrance is about 0.003 weight percent~
Other material can be added to the thermoplastic material if desired. For example, an antioxidant can be added to reduce oxidation or degradation of the odour modifying agent during manufacturing or storage.
The odour modifying agent can be blended into the thermoplastic material by various means known in the art.
The preferred method is by injecting a measured amount of liquid odour modifying agent in concentrated or diluted form directly into the extruder upstream of the extruder die before the material is extruded into film. Another method is to mix the odour modifying agent with a powder or pellet form of the thermoplastic mat~rial in a mechanical mixer or by dispersing the odour modifying agent with the thermo-plastic material in a masterbatch concentrate, which is then used in smaller quantities in the final extrusion. It was found however that injection of the liquid odour modifying agent gives a more accurate and uniform dispersion throughout the thermo-plastic material and will degrade in the resulting film at a slower rate.
The usual thermoplastic material used in garbage bags is a polyolefin such as polyethylene, or polypropylene.
These can be blended with the odour modifying agent of this invention to give the desired resuIts.

~ZS5~3g E~mple ~ portion of low-density polyethylene pellets were fed into an extruder, melted, homogenized and passed through a die where the polyethylene was then blown into film. A
container for liquid mounted on the extruder contai~ed methyl-(2-amyl-3 oxocyclopentyl)-acetate and a fragrance. The container discharged into a metering pump which introduced the liquid blend into the extruder. The amount oE solution fed into the extruder was such that the resulting extruded film had approximately 0.03 weight percent o~ methyl~(2-amyl-3-oxocyclopentyl)-acetate and approximately 0.003 weight percent of the fragrance.
Plastic garbage bags made from the above film exhibited a definite reduction in odour of the garbage contained therein when tested at a distance of five feet.
The fragrance could not be detected at the same distance but a trace of the fragrance could be detected when the bag was tested at a distance of one foot prior to packing the bag with garbage.
Consumer tests were carried out to determine the , practical performance of thr~e types of plastic garbage bags in suppressing the odour of a standard prepared garbage mixture enclosed in each of the bays. One type of bag was made from a polyethylene film containing 0.07 weight percent of the odour modifying agent, the second type of bag was made of polyethylene film containing 0.03 weight percent of the odour modifying agent and the third type of bag consisted of polyethylene film without any odour modifying agent.
