Performance & Material Features
High-density cellulose fiber matrix withstands >50,000 dry-flex cycles without delamination, preventing midsole collapse.
Thermal resistance up to 180°C prevents shrinkage during automated hot-melt adhesive-lasting processes.
High vapor permeability accelerates perspiration dissipation, reducing internal mold growth and odor buildup.
Non-gassing chemical binder eliminates sulfur migration, preventing discoloration of shoe linings.
Thickness, Density & Custom Options
Caliper options from 0.9mm to 2.5mm in standard sheets (1.0m x 1.5m / 0.9m x 1.5m) or slit rolls.
Tailored board density and rigidity formulations calibrated for formal footwear, casual sneakers, and heavy-duty work boots.
Custom board coloration and direct surface private-label brand logo printing based on buyer tech packs.
Precision pre-die-cutting and custom shaping services matching proprietary shoe last profiles.

FAQ
Q: What types of shoes can use Paper Insole Board?
A: Paper Insole Board is commonly used for leather shoes, casual footwear, sneakers, and work boots. Different density and stiffness options can be adjusted according to shoe structure requirements.
Q: What support do you provide before mass production?
A: Free evaluation samples and pre-production approval samples are available to confirm thickness, hardness, and shoe assembly compatibility before bulk orders.
Q: What advantages does your Paper Insole Board have compared with standard paper board?
A: The reinforced cellulose fiber composite provides higher stiffness retention, better delamination resistance, and improved durability during repeated shoe flexing.
Q: What testing reports are available for Paper Insole Board?
A: Testing reports covering tensile strength, ply adhesion, and stiffness performance can be provided according to SATRA TM11, ISO 22770, SGS, or TÜV verification requirements.
Q: How does Paper Insole Board perform in humid environments?
A: The cellulose fiber structure is treated to control moisture absorption below 12% after 24 hours, helping maintain shoe shape in humid storage and wearing conditions.
Q: Does the Root Cause Analysis process provide a written report the buyer can keep for internal quality audits?
A: Yes, the RCA resolution includes a written summary report detailing the identified defect cause, corrective action taken, and preventive measures implemented, provided to the buyer alongside the standard claim resolution documentation.
