Custom PP L-Type Folders
Custom PP L-type folders are polypropylene document pockets with two adjacent open edges for inserting and removing papers. In a conventional portrait orientation, the top and right edges are open while the left and bottom edges form the joined sides. Confirm the required orientation in the drawing or sample.
Asia Supply Source helps brands, distributors and business buyers source PP L-type folders from China for branded document presentation and stationery projects. We help coordinate document fit, material references, logo artwork, physical samples, quantities and packaging.

Custom PP L-Type Folders: Opening and Document Fit
An L-type folder is a pocket format. It should be specified by its opening direction, finished outside dimensions and usable space for the intended documents. A general folder name does not define capacity or paper fit.
- Identify the actual document dimensions and the number or thickness of sheets to be inserted.
- Confirm which two adjacent edges open and where the joined edges sit.
- Specify any thumb cutout, panel offset or corner detail using a drawing or reference.
- Review whether the document edges should be flush, covered or accessible in the proposed construction.
A flat sample can establish whether the sheets insert and remove as intended without catching at a joined edge. A reference such as A4 or A5 is useful, but the final usable space and proposed construction still need confirmation.
For projects using A-series paper formats, ISO 216 provides a reference for trimmed paper sizes. Confirm the actual document dimensions and required sheet stack separately, then review the folder’s usable space and opening with a physical sample.
Logo Printing for Custom PP L-Type Folders
Confirm the PP sheet reference, thickness, color, transparency and surface finish. Clear, translucent or colored appearances should be evaluated using the actual material sample rather than a screen image alone.
Provide the logo artwork, print area, placement, colors and any required text. The production department should propose an appropriate printing approach for the selected PP surface and design. Review the printed result with the intended document placed behind it, particularly where visibility or contrast matters.
Do not infer recycled content, archival suitability or a particular performance standard from the PP name. Include any such requirement in the brief so the actual material and documentation can be assessed.
Folder specification guide
| Buyer requirement | What to specify | What to review |
|---|---|---|
| Document fit | Actual paper dimensions and intended sheet stack | Usable space, insertion and edge coverage |
| Opening geometry | Open sides, joined sides and any cutout | Correct orientation and access |
| Material appearance | PP reference, thickness, color and finish | Transparency and feel with the papers inside |
| Branding and packing | Print file, position, versions and folders per pack | Readability, print appearance and pack counts |
Document and print sample checks
An artwork proof checks the layout and text. A finished folder sample is needed to check the pocket, joined edges, opening and printed material together.
- Insert the intended documents or a representative stack and check access.
- Inspect the joined edges, corners and any cutout against the agreed sample.
- Compare material color, transparency and finish with the approved reference.
- Review logo position, print detail and appearance with papers behind the front panel.
- Check the agreed handling conditions, print transfer concerns where relevant, and packaging that protects the folders.
Record the document size, artwork version and approved folder sample together. The custom product sampling guide helps keep those approvals consistent during production follow-up.
Custom PP L-Type Folders: RFQ Checklist
- Document dimensions and the intended sheet count or stack thickness.
- Finished folder dimensions, usable-space requirement and opening orientation.
- PP material reference, requested thickness, color, transparency and finish.
- Cutout, panel offset, corner or other construction details.
- Logo and text files, print placement, colors and number of artwork versions.
- Quantity split by color and print version, folders per pack, packaging, destination and required arrival date.
Specify whether the folder is supplied empty or packed with documents or other stationery. For a combined set, identify the contents and complete-set quantity separately. Our RFQ checklist helps structure a comparable inquiry.
Frequently asked questions
What makes the folder L-type?
The pocket opens along two adjacent edges while the other two edges are joined. Confirm the required orientation and construction in a drawing or physical sample.
Can I choose a standard document size?
Provide the actual document dimensions and intended stack. A named size helps identify the use, but the usable space and finished construction still need sample confirmation.
Can the front carry a company logo?
Supply the logo file, position, colors and required print area for assessment. Review a printed sample on the selected PP material with the intended paper behind it.
Are the folders supplied with documents inside?
Only if document insertion is part of the agreed order. Define whether you need empty folders or assembled sets and identify the contents of each unit.
How are quantities, costs and timing confirmed?
They depend on material, dimensions, construction, print versions and packing. Share the specifications and required arrival date for project-specific assessment.
