We often get questions about what the difference is between the types of sealing methods used for bin liners and garbage bags. Well, here is the run down.
A Star Seal bin liner is aptly named. It looks like a star. This seal provides exceptional strength because it is folded several times over the underside of the bin liner before being sealed. This seal is:
Flat Seal trash bags are self explanatory. Just as the name infers, a flat seal is simply a two-dimensional bag with a bottom seal. Unlike the star sealed bag which folds it’s plastic multiple times, the flat seal allows for a larger amount of volume inside for waste. Flat seal bags are generally leak-proof, but because they are 2 dimensional, they do not conform very well to the shape of most rubbish bins.
With so many bin liners and garbage bags available from so many places - what is the best way to figure out the most appropriate bag for your needs?
Well there are really only 2 steps.
That's really all their is to it! However, you should be mindful of a few important things...
THICK, HEAVY GAUGE BAGS OF POOR QUALITY
"Thick, heavy gauge bags of poor quality" are quite insidiously designed. This is because in the past - large buyers had tendered out these types of products on an "as specification" basis. These “Thick, Heavy Gauge, Poor Quality” bags would always pass all weight / gauge testing procedures without any problem.
However, in actual use – there were virtually useless. They were made from the cheapest raw material and the resin was diluted with various additives designed solely to add weight to the end product. The resulting final product would perform horribly on tensile strength and elongation tests. This meant that the final product would be thick, heavy and be ripped and torn with ease.
Whilst they could pass all weight / gauge testing - they ultimately failed spectacularly in real life applications.
We were quite frustrated with these products and made a video to demonstrate the problems with them - which can be seen below.
This video was created to show how easily the heavier bag ripped under pressure – particularly when compared to the Maxpak GH16 product.
FILM THICKNESS IS NOT A SATISFACTORY STANDARD FOR JUDGING OVERALL STRENGTH
Essentially, film thickness is no longer a satisfactory standard for judging overall strength. The development of resin grades in the industry have allowed manufacturers to produce end products which use less raw materials yet outperform previous generations of product. For example, one of our best selling products the GH16 is one of our thinnest products. It can be seen under 20kg test load below.
Previously, it would not be possible to get such a thin bag to carry such an excessively heavy load.
The GH16 was a ground breaking product for our company and continues to be commercially successful for our company. Never before had such a cost effective bag been able to perform so well. Whilst it took some time for this market to be developed, it is now a mainstay for our Company.
Each manufacturer has its own blend proprietary formulations, so the proportions of these materials will vary from one producer to another. The best way to determine the correct liner is to actually test some suggested samples.
This sounds easy - because there are common descriptions such as "72 litre bin liner", or "240 litre garbage bag", etc. etc. But did you know that these "descriptions" of bin liners actually vary throughout Australia? For example, a "72 litre garbage bag" in Melbourne can be different to a "72 Litre bin liner" in Adelaide, Perth, Brisbane or Sydney! That's because the "litre" description came from the garbage bin manufacturers, who all had slightly different ways of doing things.
The best way is to know exactly what bin liner dimensions (length and width) you need. If you aren't sure, or if you have a custom sized garbage bin receptacle then you can use the following method to estimate the ideal size you need:
The GH82W has now arrived, 82L bin liner in white!
There are 500 pieces per carton, with a size of 91L X 79W.
In SA, ACT, NT and Tasmania, certain types of plastic carry bags have been banned. Not content with this, the ACT Greens party are now calling for a complete plastic bag ban. The reason for this is emergence of substitutes which are still polymer based.
The pros and cons of plastic bag ban legislation are too lengthy to mention. Some of the issues regarding bin liners, degradable and compostable bags, and carry bags alternatives are mentioned in previous posts.
I think that it is important to realise that realise that plastic bags were a environmental step forward from the days of widespread paper bags usage. Paper bags have much more detrimental environmental impact than their plastic equivalents.
In fact, due the low amount of energy required to produce them, some studies in the UK have shown that plastic bags are actually more environmentally friendly than their alternatives. The real problems are the incredibly selfish and thoughtless humans among us that discard these products as litter on our public lands.
The Victorian State Government is considering implementing and "organics plan", which would potential reduce the number of garbage bin pick ups and emphasize the recycling of food scraps.
This proposal is part of an overall drive to reduce household waste.
Such a system would impose greater requirements on the citizens to sort more of their house hold rubbish.
In other countries such as Japan and Italy , the use of multi colored garbage bags is common to help in the sorting out of household waste.
In November 2011, the ACT followed the legislative precedent set by the South Australian government in implementing a ban on plastic singlet bags. Providing bags thinner than 35 Microns became illegal. What was the result of this ban? The message from Cole's head of communications, Mr. Jon Church was not a surprise.
''Wherever plastic bag bans have been introduced, we see an increase in sales of bin liners as customers no longer have single-use carrier bags available which many households use for disposing of their waste. It is well reported that following the South Australian ban, sales of bin liners across all retailers doubled,'' Mr Church said. ''Sales of kitchen bin liners in the ACT increased by 29 per cent following the carrier bag ban.''
This mirrors experiences of similar ban throughout the world. Sales of Bin Liners skyrocket! What else is one meant to use as a kitchen garbage bag at home?
Not surprisingly, some policitician can identify the added burden and cost to families.
Liberal MLA Alistair Coe said the figures called the Government's reasons for the ban into question.
''It goes to show that the plastic bag ban is putting an extra cost on the weekly bills of Canberra families, but in addition to that, it shows that the consumption of plastic bags is perhaps remaining steady,'' he said.
I wonder what they would think if they read the UK's 2011 Environment Agency report which concluded that HDPE Singlet bags "had the lowest environmental impacts of the single use options in nine out of ten catagories".
The team at Maxpak are pleased to announce a packing refresh on the inner packing of our range of Kitchen Tidy Liners. MaxValu 18 litre, 27 litre and 36 litre tidy bags have had a change of artwork design. These small bin liners are ideal for smaller office bins and kitchen tidy bins. The new artwork can be seen below.
