In creating the Polyweld it is important the sealing of the polyester is as
permanent as the polyester itself, which is why each product
is hand-made on the patented Polyweld machine. Polyweld
is a method of sealing the edge of the polyester sheets
without using any adhesives,solvents or additives of any kind.
Through heat, this method 're-extrudes' the polyester to provide
a seal that is as strong as the original material, with a unique
smooth, rolled edge.
Features & Benefits
Polyester Polywelds offer ultimate protection for the preservation of works on paper
Suitable for the storage of photographs, documents, letters, maps, fine prints,textiles
Superior archival quality
Placing the item in a Polyweld enclosure allows the contents to be viewed without exposing the contents to contamination from handling or the environment
All enclosures are hand made from sheet Archival Polyester
Polywelds are dimensionally stable
Free from all plasticisers, surface coatings, adhesive layers and ultraviolet inhibitors
Tested and proven to withstand 500 years of artificial ageing at 105 degrees celcius & 50% relative humidity.
Order and Size
As Polywelds are individually hand made any style or size may be ordered
In general, a minimum and maximum on the dimensions of a Polyweld do exist.
However, very large or oversize Polywelds, which require folding to be welded, can
be made. Please contact firstname.lastname@example.org to discuss your
requirements. Every effort will be made to accommodate your needs.
Minimum manufacturing size is 30 x 30mm
Maximum manufacturing size is 1275 x 1275mm
We recommend enclosures with one dimension greater than 400mm be made from 100 micron polyester
