Export packaging and labeling

Slitting & Sample Matching

Amber shade, slit-roll format, and sample preparation can be aligned before bulk order so engineering validation and purchasing review use the same material direction.

Amber PI film roll inspection and export packing preparation — **Inspection, wrapping, and sample preparation** Factory-side checks support shade matching, sample validation, and export-ready roll handling.

Source-factory advantage

One source film base gives buyers tighter control from material selection to downstream conversion.

CorePI focuses on one clear material platform: single-stretched amber PI film from 18μm to 150μm, finished rolls within 1180mm, and adjustable amber shade. This focus makes material matching, sample validation, repeat orders, and converted product development more direct.

Amber PI film roll production line in a factory workshop — **Roll-to-roll source production** Production-line control supports film thickness, roll format, and repeat supply.

01 Focused thickness program

18μm-150μm production coverage, with 25μm and 50μm as common thickness choices, supports thin insulation, handling strength, tape coating, sheet conversion, and die-cut barriers.

02 1180mm finished-roll capability

Finished rolls within 1180mm, standard 1040mm width, and 500m-3000m roll length give converters more room for coating width, slitting plans, yield control, and distributor inventory formats.

03 Amber shade matching

Light to deep amber control supports appearance targets, customer sample matching, and repeat-order consistency.

04 Film-to-product continuity

The same base film can move into slit rolls, sheets, tape materials, die-cut insulation, and laminated structures with clearer material continuity.

Industry advantages

Advantages of this single-stretched amber PI film across downstream industries.

Electrical insulation

Stable insulation performance with flexible thickness selection.

For electrical insulation buyers, the key advantage is the 18μm-150μm range: it helps balance dielectric performance, wrapping flexibility, layer thickness, and heat resistance across motors, transformers, cables, and electronic assemblies.

Evaluation dimensions What electrical insulation buyers usually compare

Dielectric strength Thermal endurance Thickness stability Wrapping flexibility Roll width and slitting Batch consistency

Amber PI film sheets, slit rolls, and die-cut insulation samples — **From film to sample formats** Slit rolls, sheets, tape material direction, and die-cut insulation validation.

For tape converters Wide rolls within 1180mm reduce format limitations. Amber shade control and thickness selection support coating, slitting, and high-temperature masking tape production.

For insulation buyers 18μm-150μm thickness coverage supports layer insulation, barriers, motor systems, and high-temperature electrical assemblies where material stability matters.

For electronics and FPC teams Source-factory control helps engineering teams validate thickness, surface appearance, sample rolls, and repeat purchase consistency before scale-up.

Supplier capability

Supply capability built around single-stretched amber PI film.

CorePI supports overseas buyers with a focused PI film platform, controlled amber appearance, wide finished-roll supply, sample validation, and project-ready documentation. The offer is specific enough for engineering review and practical enough for purchasing.

Finished amber PI film rolls prepared for shipment in a factory dispatch area — **Finished roll staging for shipment** Organized outbound roll batches support repeat orders and overseas project delivery.

18μm-150μm film program A defined production range with common 25μm and 50μm options supports electrical insulation, FPC evaluation, tape substrate use, battery barriers, motor insulation, and industrial conversion.

Finished rolls within 1180mm Wide roll supply, 1040mm standard width, and 500m-3000m roll length support coating, slitting, sheeting, die-cutting, and distributor stock planning with fewer width limitations.

Amber color depth control Light-to-deep amber adjustment supports sample matching, visual consistency, and downstream product appearance requirements.

Same-material conversion route Raw film supply can extend into slit rolls, sheets, tape materials, die-cut insulation, and laminated structures based on the same PI film platform.

Validation-ready samples Sample packs, slit roll samples, and shade-matching samples support engineering checks before order planning.

Export project support TDS, SDS, RoHS / REACH information, English labeling, neutral packing, and project-based quotation support overseas procurement.

Mechanical performance data Tensile strength values of TD ≥180 MPa and MD ≥220 MPa, with TD and MD elongation ≥40%, support technical review.
