Functional Films & Release Materials

OCA Die-Cutting, Carrier & Release Solutions

A coordinated converting package for optically clear adhesive: dimensional support during die cutting, controlled waste pickup, liner exchange and clean sheet delivery. OCA is the permanent adhesive; EC-OC carriers, EC-WE waste films and EC-RS/RF/RN liners are process materials removed before final bonding.

Optical and electronic converting processes that restrict silicone transfer

HOW IT WORKS

Temporary films control a permanent adhesive through converting.

01OCA is the permanent optical adhesive. Carriers, waste-stripping films and release liners are temporary process materials that stabilize it until the correct removal step. Confusing these roles can lead to the wrong drawing, liner sequence or customer instruction.

02During rotary or flatbed die cutting, the carrier controls dimensions and supports the soft adhesive. A waste film must lift the intended matrix without lifting finished parts. Release liners must provide a stable light/heavy relationship after dwell, storage and thermal history.

03Release force is not an intrinsic number without a method. Reference tape, roller, dwell, temperature, humidity, peel angle and speed must accompany every reported result.

KEY BENEFITS

Performance framed around the application.

Benefits are evaluated on the intended substrate, process and finished assembly.

APPLICATION WORKFLOW

From material definition to a qualified production stack.

Qualification links the material, converting route and customer production line.

01Map every layer

Identify OCA, light/heavy liner, carrier, waste film and the removal order.

02Stabilize cutting

Set web tension, lamination pressure, die depth and registration.

03Strip & relaminate

Balance waste pickup with part retention and clean liner exchange.

04Deliver clean sheets

Qualify particles, edge deformation, release aging and customer handling.

VALIDATION PLAN

Evidence to collect before specification release.

Use representative substrates, process conditions and aging sequences.

Carrier peel and dimensional stability through the die-cut sequence
Waste-stripping margin across web speed and stripping geometry
Light/heavy release after dwell, heat aging and storage
Particle, residue, silicone-transfer and static-control inspection

TECHNICAL FAQ

Questions engineers ask before a line trial.

Resolve the material role, interfaces and process window before sampling.

Is EC-OC an optically clear adhesive?+

No. EC-OC identifies the OCA carrier family. EC-OA identifies permanent OCA optical adhesive. The different codes intentionally prevent a process carrier from being confused with the adhesive itself.

Can silicone release liner be used with every OCA?+

No. Acrylic and silicone adhesive systems can require different release chemistries. Fluorinated or silicone-free liners are selected only after compatibility and contamination review.

Can ECLEAR recommend a grade from an application description alone?+

A first shortlist is possible, but a production recommendation requires the substrate, layer construction, equipment, process sequence, test method and acceptance criteria. ECLEAR normally moves from requirement definition to laboratory matching, samples, line trial and a frozen approved specification.

Are the values shown on this page guaranteed specifications?+

No. Website values and constructions are selection guidance. Guaranteed limits, test conditions, packaging and shelf life are controlled only by the latest ECLEAR-approved TDS, quality agreement and customer qualification record.

RECOMMENDED APPLICATIONS

Where this platform is evaluated.

Each application still requires stack-level compatibility and line validation.

PROCESS WINDOW

Parameters to control.

Record the complete process window, not only one nominal setting.

Map every liner and process film to the exact removal step.
Validate unwind, lamination pressure, die depth, web tension and stripping angle.
Test release after representative dwell, aging and storage.
Approve particles, residue, adhesive deformation and bubble performance on the customer line.

SELECTION QUESTIONS

What we need to know.

These inputs allow ECLEAR to narrow the grade and validation plan.

Q1What is the OCA chemistry, thickness and original liner construction?
Q2Which face is light release and which is heavy release?
Q3What die-cut sequence, web speed and waste geometry are used?
Q4What cleanliness, static-control and sheet-delivery requirements apply?

FAILURE RISKS

What a disciplined trial should expose early.

Early failure checks reduce scale-up risk and prevent false material comparisons.

Confusing the permanent OCA with its temporary carrier

Waste film lifting finished parts

Release-force drift after heat or aging

Silicone transfer or contamination in a restricted process
