Polyester film converting
Polyester film slitting, sheeting and converting.
We slit, rewind, sheet, guillotine and die cut polyester film to your exact specification, and add corona treatment where your process needs it. Send us your own material, or let us supply the film as well.

Trade and toll converting
A converting partner for film users and other converters.
PSG has converted polyester film for more than 40 years, and in 1983 it became the largest polyester film converting plant in the UK at the time. Today our trade conversion team converts film for manufacturers, printers, packaging companies and other converters who are at capacity, need a short run, or want to outsource a process that disrupts their own lines.
You can supply the material and we convert it to your specification (toll converting), or we supply the film from stock and deliver finished reels or sheets ready for your line. Either way, every job is run to an agreed specification and packed and labelled the way your goods-in team expects.
Trade Conversion Services
Converting services
Polyester film converting services.
One supplier for the film and every step needed to turn it into the reel, sheet or part your process uses.
Slitting and rewinding
Master rolls slit to narrow reels with clean edges, at your width, length or diameter, core size and winding direction (treated side in or out).
Sheeting
Reels cut into sheets using our sheeting facilities, from small formats to large sheets, counted and packed to your pack quantity.
Guillotining
Precision guillotining of polyester, paper, card and other materials into blanks and sheets cut to exact tolerances.
Tissue interleaving
Tissue interlaced between sheets to prevent scratching or abrasion of optical, printed and archival surfaces.
Core cutting
Cores cut precisely to 3 inch (76 mm) and 6 inch (152 mm) for your reels or your own winding.
Die cutting and laser cutting
Components cut to drawing, such as custom gaskets and shims, washers, insulators, spacers and window patches.
Corona treatment
Single or double-sided treatment to raise surface energy for printing on polyester film, coating and laminating, as treat-and-return or in-line with slitting.
Manufacturing cells and stock
Bespoke manufacturing cells and stock management, so converted film is ready when your production needs it.
Capabilities
Polyester film converting capabilities.
These are the limits we work to on polyester film. Achievable sizes and tolerances depend on the material, its thickness and the finish, so send us your specification and we will confirm what we can hold for your job.
We convert polyester and other plastic films, paper, card, board and textiles, so mixed-material jobs can stay with one supplier.
Tell us the tolerance you need
We confirm the tolerance we can hold on your material before you order.
Packed to your specification
Reels wrapped and protected, sheets interleaved and counted, all labelled as you require.

Specifying a converted reel or sheet
What to include in a slitting or sheeting specification.
For slit reels, give us the finished width and the tolerance you need, the reel length or outside diameter, the core inside diameter (76 mm or 152 mm), the winding direction, which side is corona or chemically treated or printed and whether it should face in or out, and whether joins (splices) are acceptable and how they should be marked.
For sheets, give us the size and tolerance, whether the sheet must be cut square to the machine direction of the film (important for curl and shrinkage), whether you need tissue interleaving, and how many sheets per pack.
For both, tell us how the goods should be packed and labelled, and whether you need certificates or batch information with each delivery. If anything is unknown, describe the process the film is going into and we will propose a specification for you to approve.

Converting FAQs
Polyester film converting questions, answered.
Can't find what you need? Our team is happy to help.
What is film slitting?
Slitting cuts a wide master roll of film into narrower reels. The film is unwound, cut lengthways by blades as it runs, and rewound onto cores at the finished width and length.
Can you slit film that we supply?
Yes. We convert customer-supplied film, paper, card and other materials to specification, or we can supply the material from our stock for a fully outsourced service.
What width can you slit polyester film to?
We slit reels across a wide range of widths, from narrow tapes to full-width reels. Send us the widths and tolerances you need and we will confirm them for your material and thickness.
Which core sizes do you use?
We wind onto 76 mm (3 inch) and 152 mm (6 inch) cores, and cut cores to those sizes in house.
Can you cut polyester film into sheets?
Yes. In addition to our roll cutters, we have sheeting and guillotining facilities that cut polymer, paper, card and other materials to exact tolerances, and we can interleave tissue between sheets to prevent scratching.
Do you offer corona treatment?
Yes. We can corona treat one or both sides of a film, either as a simple treat-and-return service or in line with slitting, to improve adhesion for printing, coating and laminating.
Can you die cut polyester film?
Yes. We cut polyester and other materials to drawing, including gaskets, shims, washers, spacers, electrical insulators and window patches. Send us a drawing for a quote.
Can you help with bespoke packaging and branding?
Yes. Through our approved network of partners, we can satisfy most packaging and branding requirements.
