Foam density and plate support
This Mounting Tape specs page sets out the technical information used when comparing tape options. Check the construction and application details against your plate system and the packaging format being printed.
Mounting tape selection starts with the plate thickness, sleeve or cylinder diameter, and the image type on the job. Solid ink coverage, fine reverses, and corrugated print each place a different load on the foam layer. In Gauteng plants, dry dust on the mounting table can reduce edge hold, while Durban humidity can change liner handling during application.
Check the tape construction before mounting begins. The adhesive side for the plate and the adhesive side for the sleeve are not always identical, so the release liner marking matters. A quick record of tape code, width, and compressibility helps when a repeat packaging job returns months later.
Data points that affect print
Compression value, foam hardness, total gauge, and adhesive tack all influence dot gain and bounce on press. Narrow web labels may run well on a firmer build, while flexible packaging often needs a tape that cushions impression changes across the repeat. The useful spec is the one that matches the actual press setting, not a generic catalogue line.
Compare this mounting tape entry with the relevant Press paths note and any Ink notes tied to the same print condition. Before ordering, verify tape width against the plate layout, confirm whether bridge mounting is allowed, and note any wash-up chemistry that could affect adhesive residue. Use the contact form with the tape code and plate thickness if you need the spec checked.

Checks under South African conditions
Production planning shifts around OR Tambo export weeks, Sunnyrock warehouse cut-offs, Crown Mines press schedules, and converter demand in Durban and Cape Town. On mounting tape, the useful details are cylinder diameter, plate thickness, sleeve type, and whether the job needs higher cushioning for solids or firmer support for fine text. Flag any tape lifting, edge ooze, or bounce marks seen on previous runs so the spec can be checked against the current carton, film, or label work.
Static and dust are common mounting problems at inland plants, especially where corrugated board is handled nearby. Clean the surface with the approved solvent, allow full flash-off, and inspect for fibres before the first strip is applied. During power interruptions, protect exposed adhesive from airborne contamination rather than leaving partly mounted plates uncovered.

Job details worth sending
Send the press model, substrate, plate brand, plate thickness, and the tape code currently in use. Mention whether the issue is plate lift, edge marking, bounce, dirty print, or difficulty during demounting.
Include the repeat length, print width, and whether the work is labels, flexible packaging, or corrugated. If a previous tape failed, note where it failed on the cylinder and after how many impressions the problem appeared.
