This is a very common question; the answer primarily depends on the heat of beverage you intend to serve. We stock a wide range of cups from single-wall plain cups, to our newest triple wall "Ultimate" Paper Cups. The key difference is the insulating properties of the specific cup type.
Single wall cups are perfect for warm drinks; however piping hot coffee would be rather uncomfortable to hold without the use of a cup sleeve (available seperately). Due to their single-wall construction there is no additional layer to insulate the heat of the drink.
Double wall and Ripple cups are specifically designed for far greater heat retention, the dual layers work in a similar way to a thermos flask; trapping air and isolating the customers hand from hot beverages. In addition to this, the extra rigidity is ideally suited to "coffee on the go".
With different coffee shop and drinks providers favouring different disposable cup materials, it is interesting to find out which is the most effective insulator. Perhaps the best way to discuss the insulation properties of a paper cup is to compare it with another commonly used non-china cup material such as polystyrene. This can be done by performing a simple test to show whether the polystyrene or paper cup kept the tea it contained hotter for longer.
Differences between Paper cups and Polystyrene containers
The heat retention test involves pouring 200 ml of boiling water into a polystyrene cup and the same amount into a hot drink paper cup to find out which is the better insulator. For a wider comparison you could also use a plastic container as part of the test to see how its insulation properties compare. We all know each of these vessels will provide a certain level of insulation, but this test can help show which is the best method of keeping liquids heated.
How to measure the temperature
You can use a thermometer to measure the temperature of the liquid. Taking a heat reading every minute for ten minutes, then again at 20 minutes and 30 minutes, will help to show whether the paper cup is the best insulator. You can record these findings as a graph if you wish to make the results clearer.
Heat analysis
In a similar test, cup and food container specialist Contexpan found that the liquid in both cups dropped in temperature quite quickly during the first five minutes, from around 100 degrees centigrade to around 90 degrees. However, at this point, the liquid in the polystyrene cup cooled at a significantly slower rate than the paper cup, remaining at around 80 degrees after 25 minutes compared with the liquid in the paper cup, which had dropped to around 70 degrees.
The findings
The results state that the polystyrene cup is the better insulator, with the paper cup in second place. A third cup, a plastic cup, was used in the Contexpan test and this presenting inferior insulation properties, with the water temperature falling to below 70 degrees centigrade after 25 minutes. However, companies such as Event Supplies are now manufacturing ripple disposable hot drink paper cups with an air pocket in between to trap the heat and provide an extra barrier of insulation. Although conclusive findings have not been compiled, early indications suggest that these new double walled cups will be even better insulators than their Polystyrene counterparts.
Event supplies stock a huge range of quality catering disposable items used throughout professional catering businesses, whether you are organising a large event or small party, event supplies service, prices and product range ensure your catering disposable needs are exceeded.

Paper Coffee Cups
There are a lot new Ripple cups emerging into the market at present, and some very competitively priced ones to boot.
The cost of making these products does not vary much from producer to producer, the cost of the right type of materials doesn't change either, factoring in economies of scale (purchasing power) will not change things a lot either, so how can there be massive differences in the cost price of Ripple Cups from one seller to another? Well, there is only really one way to reduce cost - use less expensive materials.
Unfortunately, the material some suppliers are compromising in order to reduce the cost of this product is the quality of the paper used.
Despite the the recycling efforts of late and green initiatives generally our beleaguered government sometimes get things right, in particular rules regarding goods which come into contact with foodstuffs. It is against the law for any product which comes into direct contact with foodstuffs to be made using recycled material for the simple reason that untreated paper (that may have once been lavatory roll for example) has the potential to make people ill if filled with hot liquid (such as coffee as toxins can migrate into the food. There is no way of checking what the recycled paper board was once used for - it could have contained anything and make people very ill.
All our Ripple Cups are made with food grade board and are sent for testing with PIRA (Printing Industry Research Association) who test the cups to make sure all the paper board used in their creation is food grade and the product is fit for purpose. Any trace of recycled material and the coffee cups would fail the test and will not be fit for purpose.
You might ask how firms can 'get away' with using or selling these cups without lawsuits etc? I suspect few of you reading this were aware that this could happen? Most people simply assume that organisations will check the quality of the Double Wall Cups used or sold by them. If you became ill after a cup of coffee would you look suspiciously at the paper cup, or wonder if the milk was off? I bet you would suspect the Paper Coffee Cup least of all.
Generally the only firms requesting food contact certificates to be delivered before delivery of Triple Wall Cups are the likes of KFC and the other large restaurants and coffee shops but any firm selling or using disposable cups should be asking for these certificates too. The first organisation to get sued will be the one without the correct documents.
To help you check if you may have unsuitable cups there is a check you can carry out yourself. Triple wall are also often described as 'triple layer cups' and there is one simple way to check if your ripple cups are produced using the correct board quality, and that is to tear the outer layer of the paper cup to reveal the hidden third layer of board.
Coffee Cups using unsuitable recycled board will be brown or grey, the proper legal board will normally be white.
