Polyimide Tape Log Roll
OPALUS PACK is a polyimide tape log roll manufacturer supplying stable roll material for tape slitters, die-cut converters, and electronics material processors. This roll is made for secondary converting, not retail small-roll use. Each batch is checked for unwind feel, edge condition, adhesive drag, and roll face stability before release. Under standard slit-test conditions, width deviation is typically controlled within +/-0.2mm to support smoother slitting, rewinding, liner lamination, and die-cut processing.
- Material: Polyimide film
- Adhesive: Silicone or acrylic adhesive
- Color: Amber, black, or custom
- Log Roll Width: 10mm-500mm
- Roll Length: 33m-500m
- Core Size: 25mm, 32mm, 38mm, 76mm
Product Overview
Polyimide tape log roll is used when a converter needs a wider roll format before making final slit rolls, linered parts, or die-cut pieces. For this type of material, heat resistance is only one part of the decision. The roll also needs to sit properly on the shaft, unwind evenly, keep a clean side wall, and give repeatable results after secondary cutting.
For a typical 50um silicone adhesive structure, OPALUS PACK samples thickness at three points across the roll width. Adhesive appearance is checked under light to observe coating streaks, uneven wetting, or visible adhesive build-up. During trial slitting, the side edge is reviewed for burr level, adhesive drag, and roll-side cleanliness.
A converter-ready polyimide tape roll should pass through slitting knives, rewind shafts, web guides, and die-cutting equipment without constant adjustment. Internal winding checks include 100m+ continuous unwind observation to see whether release remains smooth and the roll face stays flat after handling. Self-wound and release liner formats are both available. For repeat jobs, roll size, core ID, adhesive type, batch number, coating lot, and production date can be recorded.
Benefits
- Stable unwind helps reduce tracking adjustment during slitting and rewinding.
- Clean edge quality is checked after trial slitting to reduce burr and adhesive drag.
- Low wrinkle roll face supports smoother feeding on die-cut and laminating lines.
- Adhesive coating consistency helps keep peel, release, and rewind behavior predictable.
- Custom log roll width and length reduce waste in secondary conversion.
- Core size options match common slitting shafts and rewinding machines.
- Batch records support repeat production for electronics material converters.
- Linered format is available for kiss-cut parts and part transfer.
How Does Roll Formation Affect Slitting Results?
Roll formation directly affects how a polyimide tape log roll behaves on a slitting or rewinding line. If the roll is wound too tight, too soft, or with uneven edge alignment, the operator may see tracking drift, edge lifting, wrinkles, telescoping, or inconsistent finished roll appearance. A good log roll should feel balanced during unwind and keep a neat side wall after cutting, especially for narrow widths or longer runs.

Applications
- Tape slitting factories converting jumbo or log rolls into narrow finished rolls.
- Die-cut converters producing die-cut polyimide tape material for insulation parts and linered components.
- Electronics material converters needing stable polyimide tape jumbo roll supply.
- Rewinding operations requiring controlled length, core size, and rewind direction.
- Laminating processes combining polyimide tape with release liner or other films.
- OEM converting projects requiring repeatable adhesive, thickness, and roll appearance.
What Should Converters Check Before Slitting Polyimide Tape Log Rolls?
Before running a log roll for slitting and rewinding, converters should check more than film thickness and adhesive type. The first 20-50 meters of unwind often show whether the roll is easy to process. Edge drift, sudden tension change, coating variation, or roll face wrinkles can affect slitting alignment and blade wear. For die-cut or linered projects, release force and liner stability should also be reviewed before production.
FAQ
Is this supplied as finished small rolls?
No. It is mainly supplied as a log roll for slitting, rewinding, laminating, or die-cut processing before final use.
Can OPALUS PACK control the slitting tolerance?
Yes. Standard tolerance is typically +/-0.2mm after specification confirmation. Tighter or narrow-width projects should be reviewed according to roll width, adhesive type, and machine process.
Can the roll be supplied with release liner?
Yes. Self-wound and linered formats are available. Linered rolls are usually selected for die-cutting, kiss-cutting, and easier part handling.
What data should be confirmed before production?
Confirm log roll width, roll length, core size, thickness, adhesive type, liner requirement, rewind direction, tolerance target, and downstream converting method.
