GreenBeans Sandwiched PUL
Two layers of 100% polyester interlock fabric laminated together with TPU (sandwiched) in the middle to make GB sandwich PUL. Standard PUL is the same, just one less layer of fabric. Sandwich PUL is twice the weight per meter, as it is twice the fabric.
Sandwich is used to describe how it is made and composed, and has nothing to do with usage. If you are making Sandwich Wraps, you are best to use Standard PUL - as it is less rigid than Sandwich PUL and will have the 'wipable' side desired for this usage, rather than both fabric sides.
Sandwich PUL is very rigid and stiff in comparison, and does not allow as much discreetness in incontinence wear that standard PUL allows. It is stiffer, has more noise, and thicker so bulkier so more visible.
This is our own PUL, manufactured by ourselves to the highest standard possible and will outlast every other product we are aware of in the market place.
In our testing so far, we are yet to destroy, or put any sign of wear of it laundering on 300 standard cycles, at 90 degrees centigrade.
We continue to test the performance of our PUL, to give an upper limit, but so far it has stood up to, and outlasts even the old Fabrite product on every test.
Sandwich PUL is perfect where you are looking for more durability from wear and tear - like your child dragging their wet bag along behind them on the asphalt all the way home from School. Our Sandwich PUL does not last any longer than our standard PUL with normal wear and tear through laundering and usage as a fabric in a garment worn.
Frequently Asked Questions:
Is your PUL Food Safe? - YES
Is your PUL BPA free? - this is an oxymoron question - PUL is an acronym for "PolyUrethane Lamination" - not "BPA Lamination". PUL would not and could not be called PUL if it used BPA instead of Polyurethane. BPA is a type of stiff and rigid plastic, Polyurethane is a soft and pliable form of a plastic mixed with rubber.
The question often comes from people looking at USA PUL - as in the USA any product sold for Children must be tested for BPA and be BPA free to meet CPSIA regulations. Because they have to specifically test all the components to be BPA free - and the cost to test is around $30 - most companies selling any fabrics for children's products do the test and claim they are BPA free simply as in the USA it is required by law, not that there is any risk of PUL containing any BPA.
One should never worry about any PUL having BPA - as it simply shouldn't have any in it. And if a PUL had BPA in it - and the person selling it is calling it PUL - they are lying to you to start with as it isn't PUL - so why do you think they would tell you the truth if it had BPA in it or not?
As we also sell PUL into the USA, we run all our products through tests to meet CPSIA regulations, including BPA testing - and in doing so naturally our PUL is BPA free.
Is your PUL Phthalate free? - Again often due to this being required to be tested under CPSIA regulations - and yes our PUL is Phthalate free and tested so for USA CPSIA testing. Furthermore our PUL is fire retardant and will not catch on fire - which has been proven in numerous fire retardant testing required under USA CPSIA testing. It will burn if you put a naked flame to it, but struggles, and as soon as the naked flame is removed, it self extinguishes. One should be assured they have zero risk of flammability of our PUL products.
Our width is 25% more than most other products out there, when looking at the prices of other products, you need to take both width and yield differences into account. Most get a better yield out of a wider roll, fitting more nappies in per square metre.
What is PUL?
"PUL" is an acronym for "PolyUrethane Laminate". It is a process of bonding two fabrics together with a layer of PU (Polyurathane sheet) to make them seem as one. PUL was never designed or invented to be in consistent contact with water or laundered as we do in Modern Cloth Nappies, however PUL is the best barrier fabric when the right process with the right materials are used to manufacture it.
A reliable waterproof layer is the single most important component of any nappy system, making investment in quality PUL fabric invaluable, and ensuring your nappy has the potential to survive many children.
Yes there is many people that can supply you a cheaper PUL, we can too, but we don't as it fails within 3-9 months of normal usage. The PUL we stock is the best and will not fail before it should, and if laundered correctly, can easily last for 5 years or more. With PUL, you get what you pay for, and how good your PUL is determines how long your nappy lasts.
1mil vrs thicker
We stock 1mil PUL as our research and testing has found 1mil PUL more flexible to work with, not "crackly/crunchy" and less likely to crack or split over time as thicker PULs can be. It also provides a high level of breathability. The thicker the polyurethane layer, the less the breathability.
We suspect a lot of other suppliers stock a thicker PUL as they are not using the best methods or materials in producing their PUL, and as such have to use a thicker PU sheet to get a little extra life out of it, but still will be a very substandard product.
The PUL we sell far exceeds the quality & durability of every producer we are aware of in the world. While the industry standard for PUL is to last 30-50 times through the laundry, our PUL well exceeds this many times over and many have found they get over 1,000 laundry cycles out of it.
