Material for your converter
Ask for the required roll or sheet form where suitable. Provide roll width, or sheet length × width in mm, orientation, face requirements and quantity with its unit. Do not use a finished-box size as a sheet size.
Material purchasing
Review colored E and F flute paper and board by color reference, exposed or enclosed construction, display face and print face. Confirm each paper-color combination with a sample.
Provide a physical color reference or artwork specification, identify the visible faces and review printing on the selected paper. Compare E and F profiles and exposed versus enclosed flute before agreeing a sample.

Understand the material


A — Single face: one liner + exposed fluting
B — Single wall: two liners + one fluted medium
Liners are the flat paper faces; the fluted medium is the wave-shaped layer. Layer count does not establish thickness or protection performance.
Neutral layer colors explain construction, not Kehong color specifications. Confirm actual faces and cut edges with a sample.
Single-face material has one flat liner bonded to fluting. Three-ply board has two liners around one fluted medium. These are different constructions, even if the visible face looks alike.
The current selection documents colored E and F flute in single-face and 3-ply directions. The supplied pink-white E sample is an appearance reference, not evidence that every shade is available in every construction. Confirm one paper-color-construction combination at a time.
See documented combinations| Area | Buyer check |
|---|---|
| Color reference | Supply a physical paper sample or clearly identified color reference. Review the proposed paper under the agreed viewing conditions; screen images are useful references, not approved color samples. |
| Display and print faces | Mark the side facing the customer, the reverse face and any exposed flute. Identify artwork, coverage and print position separately from the base-paper color. |
| Structure and next operation | Choose exposed single-face or enclosed 3-ply construction for discussion. State whether you will wrap, cut, crease, print or assemble the material; confirm suitability using the selected paper and sample. |
Ask for the required roll or sheet form where suitable. Provide roll width, or sheet length × width in mm, orientation, face requirements and quantity with its unit. Do not use a finished-box size as a sheet size.
Provide a drawing or the product dimensions for structure discussion, cutouts, crease lines and delivery state. Quote each part in pieces or sets and explain what one set contains.
Specify the outer box and internal components separately, including the quantity of each. Confirm assembly, appearance and packing requirements rather than assuming they are included in the material price.
Record the material family and construction; required faces and visible cut edges; roll width or sheet dimensions; quantity and unit; where the material is used; and the next process. If paper grammage, thickness or a tolerance is already specified by your converter, include it and identify the measurement object. Otherwise describe the use and discuss a sample before fixing the specification.
