MANUFACTURING

Six Controlled Stages Between Raw Film and Your Dispatch Note

Coating, curing, slitting, printing, testing and packing. Every stage has a defined window, an owner and a record which is what makes the next batch match the last one.

WHY WE COAT IN-HOUSE

Owning the Coating Step Changes What We Can Promise

A converter who buys jumbo rolls and slits them can promise a width and a length. They cannot promise a coat weight, because they did not apply it. When a customer needs more adhesive for a dusty recycled board, or less for a surface that must come clean, that request has to travel back up a supply chain and usually returns as a no.

Coating our own film means the adhesive system, the coat weight and the curing profile are parameters we set. It is also why our test data means something: we are measuring the output of a process we control, not auditing someone else's.

PRODUCTION PROCESS

From Raw Material To Finished Roll

01

Raw Material Selection

Films, adhesives and cores are sourced from approved suppliers and inspected on arrival for thickness, clarity and consistency.

02

Adhesive Coating

Precision coating lines apply the adhesive at a controlled thickness across the full web width, with inline monitoring of the coat weight.

03

Curing & Winding

Coated film is dried and cured under controlled temperature, then wound into jumbo rolls at calibrated tension for a stable, even roll.

04

Slitting & Rewinding

Jumbo rolls are slit to finished widths on automatic slitters that hold tight tolerance and produce clean, burr-free edges.

05

Testing & Inspection

Samples from every batch are tested for peel adhesion, tensile strength, elongation and thickness before the batch is released.

06

Packing & Dispatch

Finished rolls are labelled, shrink wrapped and packed to protect them in transit, then dispatched with batch traceability.

PLANT CAPABILITY

What the Line Can Run

Maximum coating width Up to 1300 mm
Adhesive systems Water-based acrylic (standard), solvent-based (on request)
Film range BOPP 38 - 65 micron, tissue carrier 80 - 150 micron
Slitting tolerance Held to specification on automatic slitters
Finished roll widths 12 mm to 96 mm standard, custom on request
Jumbo roll lengths 1000 m to 4000 m depending on grade
Printing Flexographic, up to multi-colour in line
Batch traceability Incoming film through to dispatch label

Requirements outside this envelope are worth asking about anyway - some are a scheduling question rather than a capability one.

Planning a private label programme?

Volume, artwork and lead time are best worked out in one conversation rather than three emails.

CONSISTENCY IS THE PRODUCT

A Trial Order and a Container Load Get the Same Discipline

The reason a specification drifts is almost never a machine. It is an undocumented adjustment that nobody wrote down, repeated until it becomes normal. Fixed process windows, recorded settings and batch sign off exist to stop exactly that so the roll you approve this year is the roll you receive next year.

How We Got Here

Want to See the Line Running?

Customers who visit tend to order with more confidence, because they have watched the coat weight being checked rather than read about it. The plant is in Morbi and visits are welcome with a little notice.
