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 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!

On 1st January we launched our new website/online shop. Many new pages with friendlier product descriptions (we don't use packaging industry terminology any more!) and a whole new, easier to understand discount structure, with massive new discounts particularly on multiple buys of larger items.
Our new homepage shows scrolling pictures of our stock items, broken down by category - Retail Packaging, Display Packaging, Industrial Packaging, Food and Catering Packaging, Protective Packaging, and Horticultural Packaging. Just click on the titles above each picture to see our range of packaging supplies in each category. Our site is fully search-indexed if you can't find what you are looking for. Use the search box on the right hand side of every page - just remember to enclose search phrases in " " - for example "film front bags" otherwise the search will return any page that mentions 'film', 'front' and 'bags' - and there will be LOTS of those!
We hope existing and new customers like the new site. If you have any thoughts or comments about the site please let us have your feedback.
