High-density polyethylene. From 7 microns upwards.
For nearly 40 years, we have been producing polyethylene HDPE film for use with waterproof bitumen membranes. We specialise in B2B sales to companies in the waterproofing sector offering anonymous, micro-perforato or personalised film, to our clients’ thickness and printing requirements.
Why choose our HDPE film for your bitumen membranes?
Durability of the membrane over time
The special technology we use for our thin films requires less exposure to the flame during positioning, protecting the durability of the bitumen membrane over time.
Since the technical characteristics of the waterproof mass can be altered as the membrane is heated, less exposure to the flame of the blowtorch means preserving the life of the membrane itself.
Our high-density film (HDPE) is produced with special polymers that offer an extraordinary combination of visual uniformity and guaranteed thickness.
This particular resin aids the fusion of the film during flame-spraying, significantly reducing both the timescales and costs of work.
Our waterproof film is highly personalisable,so that we can meet the needs of our customers in full. The film is currently available in black or a neutral colour, and comes in various lengths and thicknesses (from 7 microns upwards) in both micro-perforated and anonymous forms. It is also possible to customise the film with the personalised logo of our clients.
For granulated bitumen membranes, we produce the selvage, that is the film belt, printed or otherwise, in various dimensions (from 8cm upwards) and thicknesses, as per our clients’ needs. Their function is to guarantee the correct placing of the side or head membrane during application.
Approved by the NRCA
The National Roofing Contractors’ Association (USA) Thanks to various tests carried out by specialised certifying bodies on the water-proofing membranes, the NRCA has in fact established that the 7-micron film offers the best effect on the membrane during thermic fusion.
Our clients’ most Frequently Asked Questions
Yes, we use an external company to personalise films with logos as per our clients’ needs. For the printing, we use ink and water, which are less polluting than solvents. This leads to a lower impact on the environment, and is better for the health of the workers who use the combined bitumen.
The anonymous film attaches easily to hot and thick membranes.
Currently, our standard production allows for single-colour printing: blue, white or green. But we can also supply film printed in four colours, on request.
We have solved this problem for you with an innovative technical solution that prevents transfer of the print. Contact us for further information.
Our printing uses water-based inks, with a rotogravure on the inside of the coil, followed by Corona treatment of the film.
