You say P-U-L I say PUL. But let’s face it, both are easier to say than than polyurethane laminated fabric!
The most common type of PUL is a polyester knit fabric with a very thin waterproof film bonded to it. It is lightweight (ours is approx 155gsm), supple and easy to work with. And despite being waterproof it remains breathable.
The “mil” is the thickness of the waterproof film that is bonded to the fabric. The difference in thickness between 1 mil and 2 mil is imperceptible to touch. 1mil is one thousandth of an inch (.001 inch)!
1mil is perfectly waterproof and is suitable for most uses. 2 mil can be used in very wet environments but is slightly less breathable.
Our PUL can go through the washing machine up to 300 times and still retain stay waterproof. It can be washed up to 60C.
PUL can be tumble-dried on warm.
We sell the world’s only Food safe PUL that has been tested as being safe for being in direct contact with food. It’s brilliant for making sandwich bags, lining lunch bags etc.
Sewing with PUL is much easier when using a walking foot (especially if it is teflon coated). For best results use a ballpoint needle. Once you have finished your item put it in the tumble dryer on low for 20 mins and the heat will seal the needle holes.
A hidden PUL layer is a technique that sews a layer of PUL between two other layers of fabric to make something leakproof. You see this a lot in reusable personal hygiene products such as cloth sanitary pads and incontinence pads.
Yes! Items made with PUL can be washed and re-used over 300 times before needing to be replaced.
Also our ProSoft PUL and our ProSoft Food Safe PUL is CPSIA certified, meeting stringent standards by the U.S. Consumer Products Safety Commission on lead and phthalates. And is is manufactured with no harmful chemicals or finishes in controlled conditions in American textile mills.
