Paper Types Overview

abstract
The marketplace classifies paper into 11 types (kraftliner, testliner, fluting, duplex, triplex, sack kraft, white top testliner, coated board, MG kraft, greaseproof, tissue), each with distinct GSM ranges, fiber types, and end-use applications.

Overview

Paper type is the most critical matching dimension, weighted at 30% in the wiki/concepts/matching-algorithm and functioning as a binary gate: a buyer of one paper type cannot use another. Understanding the different paper types, their GSM ranges, and their end uses is essential for the marketplace's specification-based matching.

Paper Type Classification

Paper Type GSM Range Fiber Type Primary Use
wiki/entities/kraftliner 100-440 Virgin Corrugated box outer layer
wiki/entities/testliner 90-300 Recycled Recycled linerboard (cost-effective alternative)
wiki/entities/fluting / CMP 80-200 Recycled/Virgin Corrugated medium (fluted layer)
Duplex Board 180-500 Mixed Packaging cartons (white front, grey back)
Triplex Board 180-500 Mixed Heavy-duty packaging (three layers)
Sack Kraft 70-115 Virgin Industrial bags (cement, chemicals, food)
White Top Testliner 115-250 Mixed Printable packaging (white coated surface)
wiki/entities/coated-paper Coated Board (LWC/HWC) 200-450 Mixed
MG Kraft 40-120 Virgin Wrapping, interleaving
Greaseproof 30-80 Virgin Food packaging (oil/fat resistant)
Tissue (parent rolls) 13-30 Mixed Tissue products (parent rolls for converters)

Corrugated Packaging Group

The largest segment in the marketplace. Corrugated board is made from three components:

These are the most commonly traded surplus papers because corrugated packaging production is massive (C-flute alone has ~80% market share in corrugated) and generates significant side trims and overruns.

Board Group

Specialty Group

Tissue

Tissue parent rolls are sold as surplus to converters who cut and process them into consumer products (toilet paper, facial tissue, paper towels). Very low GSM (13-30), high volume, specialized converting equipment required.

Paper Type in Container Compatibility

For wiki/concepts/container-assembly, paper types are grouped into four compatible groups. Items from different groups cannot share a container:

Group Paper Types
Packaging kraftliner, testliner, fluting, white_top_testliner, duplex, triplex, coated_board
Sack sack_kraft
Wrapping mg_kraft, greaseproof
Tissue tissue

Corrugated Flute Types

When dealing with wiki/entities/fluting, the flute type matters:

Flute Height Flutes/m Market Share Use
A 4.8mm 108-118 ~10% Cushioning, fragile goods
B 2.5mm 150-154 ~20% Canned goods, POS displays
C 3.5mm 128-132 ~80% General shipping boxes (dominant)
E 1.2mm 290-310 Growing Retail-ready packaging
F 0.8mm 400+ Niche Micro-flute, direct print

Standard Roll Widths

Paper rolls come in standard widths (mm): 610, 660, 710, 760, 810, 860, 910, 960, 1000, 1020, 1060, 1120, 1200, 1260, 1280, 1400, 1500, 1600, 1680, 1700, 1760, 1800, 1880, 1900, 1930, 2000, 2060, 2100, 2200, 2240, 2400, 2500, 2600, 2800.

Side trims (a major source of surplus) are the narrow strips left over when master rolls are cut to these standard widths.
