Quick Buyer Summary
Do not approve Tyvek® pouch printing from artwork alone. First confirm the exact material style and surface finish, then place the artwork on the finished pattern. Record the print process, ink or transfer route, Pantone target, acceptable color difference, fold and seam clearances, rub-test method and approval sample. Metallic and strongly creased surfaces can change perceived color and edge definition. Large solid areas and artwork crossing folds or stitch lines need project-specific trials. The approved reference must represent the same material, construction and packing route intended for bulk production.
Printing is one of the most visible parts of a custom cosmetic bag, but it is also where a vague RFQ creates preventable sample revisions. “One-color logo” is not a complete print specification. A supplier still needs to know the substrate, surface treatment, artwork size, coverage, color target, position, durability expectation and whether the pouch will be folded through the printed area.
Use the custom Tyvek® cosmetic bag and pouch page to define the product and material route. This guide focuses only on the printing decision.
1. Confirm the Substrate Before Selecting a Print Route
Tyvek® is a DuPont brand of spunbonded high-density polyethylene, not conventional paper. DuPont's printing guidance notes that process and ink selection require attention to the actual Tyvek® style and application.1 Ask the bag supplier and printer to evaluate the confirmed substrate rather than assuming a method that works on paper, canvas or PU will behave the same way.
Trademark statement: Tyvek® is a registered trademark of DuPont de Nemours, Inc. Rivta is an independent bag manufacturer and is not affiliated with, endorsed by or sponsored by DuPont. Material route and supporting documents are confirmed per project.
2. Build an Artwork Handoff That a Factory Can Use
| RFQ field | Buyer should provide | Why it matters |
|---|---|---|
| Artwork file | Editable vector artwork with fonts outlined. | Prevents missing fonts, rough tracing and uncontrolled resizing. |
| Finished placement | Logo width, height, center line and distance from seams or zipper. | Makes front-panel approval measurable rather than visual only. |
| Color target | Pantone reference, approved swatch or signed physical standard. | Screen color and printed color are not the same approval reference. |
| Coverage | Spot logo, repeated pattern, large solid area, metallic effect or full panel. | Coverage changes process risk, cost, hand feel and sample work. |
| Durability | Expected rubbing, folding, travel use and pass/fail method. | “Durable” has no operational meaning without a test condition. |
3. Put the Artwork on the Finished Pattern
A flat logo position can move visually after the pouch gains depth. Gussets, curved zipper lines and seam turnings change the visible front panel. Ask for a placement drawing tied to the finished dimensions and require the physical sample to show:
- distance from the logo to top, bottom and side seams;
- whether any part of the print crosses a fold, dart, piping or stitch line;
- orientation after the pouch is filled and standing;
- the acceptable effect of the material's creased surface on fine lines;
- alignment between repeated artwork and panel edges.
4. Define the Rub Test Instead of Writing “Good Adhesion”
A procurement brief should describe how the sample will be handled and what counts as failure. The right method depends on the print system, intended use and destination requirements. A practical project-specific check can define:
- dry or damp rubbing;
- the cloth or contact surface;
- number of cycles and applied pressure;
- whether the printed panel is flat, folded or loaded;
- acceptable color transfer, edge wear or cracking;
- the retained approval sample used for comparison.
Do not promise a universal result before the actual material, ink route and test have been agreed. The purpose of the test is to create a shared pass/fail decision for that project.
5. Verified Production Evidence: Screen Print on Metallic Tyvek®
Rivta completed and later repeated production of silver DuPont Tyvek® cosmetic pouches for an anonymized Eastern European skincare brand. The confirmed route used screen printing. The project evidence supports a practical rule: approve printing together with the real metallic surface, crease character, fold direction and export packing. It does not support a claim that one ink or process works for every Tyvek® style.
6. Sample Approval Sequence
- Swatch: confirm the material identity, color and surface finish.
- Print strike-off: compare color, opacity, fine lines and edge definition.
- Finished sample: check placement after sewing, turning, loading and closure.
- Rub and fold check: use the agreed method on the finished panel.
- Packing check: confirm the print is not damaged by individual packing, folding or carton pressure.
- Signed reference: record the material, print route, artwork version and tolerances for bulk inspection.

Frequently Asked Questions
Can the same ink be used on every Tyvek® style?
Do not assume so. The confirmed material style, surface treatment, print process and intended use should be reviewed together and approved by sample.
Can Rivta match a Pantone color exactly?
A Pantone target can guide development, but the substrate color, metallic reflection, ink opacity and process influence the result. Agree an acceptable physical reference and tolerance.
Should a logo cross a fold or seam?
Only after a project-specific sample confirms the visual and durability result. Fine detail, solid areas and metallic effects can change across folds and stitch lines.
What artwork format should a buyer send?
Editable vector artwork is preferred, with fonts outlined and final logo dimensions, placement and color references identified.
What is a useful rub-test brief?
State dry or damp condition, contact material, number of cycles, pressure or handling method, sample orientation and the acceptable level of transfer or wear.
