Roof application:
Membranes are commonly use as waterproof underlay beneath the roof covering, which impervious to any wind driven rain or snow that gets blown through the roof covering, even when in direct contact with timber rafters and insulation.
Printing and Slitting:
As a OEM factory, we would like to make customer's logo on the breathable membrane. Our company now have 3 printing lines, two of which are silk-screen printing. The silk-screen printing makes the logo very clear, any kind of color is acceptable; the shortcoming is the low speed of production, higher cost. and only one color logo is available.
Packing & Delivery
Packing: Normally is free PE wrap, with two inches paper core inside. Our new shrink film packing machine will be added by the end of this year. Free loading and pallet packing loading are both OK. Customer specialized label is available.
