Aller au contenu Kangchuang Paper manufactures industrial partition paper — precision-graded separator and interleaving paper engineered to protect sensitive surfaces from scratching, contamination, and damage during stacking, storage, and transport. Our partition paper is used between layers of flat glass sheets, PCB boards, solar photovoltaic cells, LED panels, and precision metal components where any surface contact mark, scratch, or chemical contamination causes rejection. Available in rolls, sheets, and custom die-cut sizes at weights from 25gsm to 120gsm — in white, natural, and antistatic grades. Factory-direct from Dongguan with free sample shipment via DHL Express to the United States.
Partition Paper
General-purpose industrial interleaving and separator paper for glass, PCB, metal, and ceramic surface protection during stacking and transport — smooth surface, consistent thickness, and low particle generation.
White Antistatic Sulfur-Free Paper
Dual-function partition paper combining antistatic surface treatment with sulfur-free composition — for PCB board separation and ESD-sensitive electronic component interleaving where both static discharge and sulfur tarnishing must be prevented.
Photovoltaic Platform Paper / Pad Paper
Specialized partition paper for solar photovoltaic cell manufacturing — placed between solar cells during stacking, handling, and transport to prevent micro-scratching on cell surfaces that reduces energy conversion efficiency.
Partition paper is a category of industrial paper specifically manufactured to serve as a physical separator between layers, sheets, or individual units of manufactured products during production, storage, and transportation. Unlike general-purpose packaging paper, partition paper is engineered for surface cleanliness, consistent caliper thickness, smooth surface finish, and low particle generation — because the products it contacts have sensitive surfaces where any defect caused by the separator paper itself is unacceptable. In the glass industry, partition paper is placed between flat glass sheets during stacking to prevent surface-to-surface contact that would cause scratching, chipping, or alkali staining. In PCB manufacturing, partition paper separates stacked circuit boards during storage and transport to prevent copper trace damage, solder mask scratching, and contamination from adjacent board surfaces. In solar photovoltaic manufacturing, partition paper protects the anti-reflective coating on solar cell surfaces during handling and shipping — where even microscopic scratches reduce cell efficiency and cause rejection at quality inspection.
Partition paper protects surfaces through three simultaneous mechanisms. First, it provides a physical barrier between adjacent product surfaces, preventing direct surface-to-surface contact that causes scratching and abrasion during stacking, handling, and vibration during transport. Second, the paper’s controlled surface smoothness (measured in Sheffield smoothness or Bekk smoothness units) ensures that the paper itself does not scratch the products it contacts — this is critical for optical glass and solar cells where the paper must be smoother than the product surface. Third, low-lint and low-particle manufacturing ensures that the paper does not shed fibers or dust particles onto product surfaces during use — particularly important for cleanroom-adjacent operations in electronics and photovoltaic manufacturing where surface contamination particles are measured and controlled. For specialty applications, additional properties are added: antistatic treatment prevents electrostatic charge buildup that attracts airborne particles to product surfaces, and sulfur-free composition prevents chemical tarnishing on metal surfaces in contact with the paper.

Partition paper is manufactured with controlled surface smoothness, consistent caliper, and low particle shedding specifically for surface-sensitive product separation. Regular packaging paper (kraft, newsprint) is designed for structural protection and void-fill — it has rougher surfaces, inconsistent thickness, and high fiber shedding that would scratch or contaminate sensitive products like glass, PCB boards, and solar cells.
The primary industries using partition paper are flat glass manufacturing and processing, PCB circuit board manufacturing, solar photovoltaic cell production, LED panel manufacturing, precision metal stamping, optical component manufacturing, and ceramic tile production. Any industry that stacks flat products with sensitive surfaces during production or shipping requires purpose-made partition paper.
Yes. Our white antistatic sulfur-free partition paper combines surface antistatic treatment (surface resistivity 10⁶–10⁹ ohms) with sulfur-free composition (<5ppm sulfur). This dual-function grade is specifically designed for PCB board separation and ESD-sensitive electronic component interleaving where both static discharge and chemical tarnishing must be prevented.
Kangchuang manufactures partition paper in weights from 25gsm (thin interleaving for lightweight components) to 120gsm (structural separator for heavy glass sheets). The most commonly ordered weights are 40gsm for solar cell separation, 50–60gsm for PCB board interleaving, and 80–120gsm for flat glass sheet stacking.
Yes. In addition to standard roll supply, we offer custom sheet cutting to any specified dimensions for your stacking and interleaving process. Sheets can be cut to match exact product dimensions with ±1mm tolerance, eliminating the need for on-site cutting and ensuring consistent coverage of the product surface.
