The early history of the paper bag

The history of paper bag manufacture is an interesting one.
The first paper bag making machine was invented by Frances Wolle in America in 1852. In 1869, Wolle with several partners, including his brother, founded the Union Paper Bag Machine Company, and the factory they opened then is still in operation today, under the control of International Paper.

In 1870, a profilic inventor, Margaret Knight, while working at the Columbia Paper Bag Co., invented a machine to make a square-bottom bag by first forming a tube of paper, which is then glued together, after which the bottom of the tube is folded in several intricate ways to form a flat bottom which is then glued to complete the bag. We sell a range of very popular Corn/Flour Bags today, that are made in a very similar way, incorporating a tubular body, but a flat bottom. A woman not to be trifled with, she fought off an attempt by a man named Charles Annan to steal the details of her machine in 1871 and patent them as his own. She successfully fought off his attempt to steal her design by showing a court all her detailed drawings, schematics and notes, which led to Mr Annan’s claim being thrown out.

In 1883, Charles Stillwell patented a machine that created a bag with not only a flat bottom that the bag could stand up on, but also side gussets that made the bag easier to fold and stack. This type of bag is still in general use today as the American grocery bag. We sell a range of similar bags as our Kraftex Bags range, but only the largest, a 28lb bag, could really be used as an American grocery bag).

The first paper carrier bag is credited to Walter H Deubner, who, in 1912,  owned a grocry store in Minnesota, USA. He wanted to find a way of increasing his sales and came upon the idea of making a paper bag that was enforced by strings running through the bag, which also acted as a handle. He succeeded in making a carrier bag that could carry weights of up to 75lbs (34kgs). Within a couple of years he was selling the bags at 5¢ each and was selling over a million a year.

Si fractum non sit, noli id reficere.

We recently made a major change to the design of our website, and the way the website applied discounts to purchases. Previously we had used a system where discount was calculated and deducted from the total of all purchases. On 1st January we switched to a system where the price of an item was determined by how many packs of that item you bought. There were different prices for 1, 2, 4 and 8 packs.

It soon became apparent though, from the feedback we received, that some regular customers were not happy with the new system, as their typical orders were not generating the same discount as with the old system.

After some tinkering with the pricing algorithm on the new system it became clear to us that the new system was not going to work well with our typical customer’s buying pattern, so from today 28th February, we have re-instated a system that discounts orders based on total order value, as before.

Well, now we know what system works best for our customers, we will try to resist meddling with it in future.  As the title says, Si fractum non sit, noli id reficere….

Local Delivery Detail Changes

Just a quick post to tell our customers that we have done a major revamp of our local delivery charges.

As before, any orders over £50.00 + VAT are delivered free within our local delivery area. If you don’t know what area this covers, you can see a map by clicking here

We have reduced quite a few of the charges, and simplified the options so that picking the right postcode option when placing an order online will be a simpler, and hopefully cheaper option.




High Density vs Low Density Polythene

We are often asked what the difference is between High Density and Low Density polythene carrier bags. People most often think that High Density must mean that the polythene is really thick, right? Actually, no. Completely the opposite.

High Density Polythene Carrier Bags are most commonly found in the food and lower end merchandise retail environments. Those really thin, strong but lightweight carriers you get at supermarket checkouts are High Density Polyethylene (HDPE). While there is only a small difference in the density of molecules in HDPE compared to Low Density Polyethylene (LDPE), the molecular structure – the way the molecules bond to each other in HDPE is that much stronger than in LDPE, so that it takes considerably fewer molecules that are in an HDPE carrier bag (due to it’s relative thinnness) to match the strength of an equivalent LDPE bag, resulting in a much thinner, lighter, and, of course, cheaper bag.
Because of the strength of the molecular bonds in HDPE it is also far less prone to stretching than LDPE, which is also a considerable factor in it’s strength compared to LDPE bags. We have probably all experienced the handle of a thick (LDPE) polythene carrier stretching when loaded with too much shopping, until the integrity of the polythene is compromised and the handle breaks. While this can also happen with HDPE carrier bags, it is much less pronounced, taking into account the comparative thinness of the material. With an HDPE carrier bag, the more likely outcome of overloading the carrier bag is that it will cut off the blood supply to your fingertips!

Where LDPE carrier bags (remember, these are the thick bags) come into their own is when an impression of quality is desired. If you buy an item of designer clothing in an up-market store, they are not likely to give it to you to take away in a flimsy HDPE carrier bag.

So that is the difference between HDPE and LDPE (often just HD and LD) polythene carrier bags in a nutshell.
Actually, taking about the tendency of LDPE carrier bag handles to stretch and break under load, that is why ‘Varigauge’ polythene carrier bags exist. These are carrier bags that are constructed of thicker polythene at the top of the carrier, where the handle is, than at the bottom. You might think that they should be thicker at the bottom, where all the weight is settled, but no – it’s the handle that needs the strength.
Well, we hope we’ve cleared that up for you!

Major upheaval – Web Host Change.

We apologise to anyone experiencing difficulties with our website around 22nd-24th January.

We were getting frequent error messages when trying to access our site, due to problems with our hosts servers, so on the 23rd we changed our web hosting company. It’s a shame, as we had been with our old hosting company for about 15 years and not had too many problems.

There are a few issues to iron out, but we hope to be running smoothly again by Saturday 25th.


Hello world!

Welcome, one and all, to our shiny new blog!

We plan to make this an active place, where we discuss all things to do with packaging, and occasionally other things too.

We hope to see you here on a regular basis!
