A 3D mylar bag mockup places flat artwork on the selected bag format so the design can be checked before production. A digital proof is the screen document used to review and approve artwork placement, construction notes, and supplied copy. CPL provides free design support, a free digital proof, and a 3D mockup process for the selected direction.
What does a 3D mylar bag mockup show?
A 3D mylar bag mockup shows how artwork sits across the bag panels, seams, opening, and outline. It can reveal a logo too close to an edge, copy that turns onto a side panel, or artwork that misses an irregular cut. The mockup is a visual check, while the proof notes identify the actual material, closure, finish, and window.
How does a mylar bag proof move toward production?
A mylar bag proof moves toward production after the product, bag format, finished size, artwork, opening, closure, and finish are defined. CPL prepares the digital proof and 3D view for the selected construction. Review panel placement, copy, color direction, window position, and edge clearance. Production is typically 8 to 10 business days after proof approval, plus delivery.
- Send the product, bag format, and finished dimensions.
- Provide artwork, logos, copy, colors, and any available dieline.
- State the zipper, heat-seal, tear-notch, hang-hole, or window direction.
- Inspect orientation, panel balance, seams, and edge clearance in the preview.
- Approve the proof after the design and construction match.
What should you inspect on a mylar bag proof?
Inspect the front panel first, then check the back, sides, opening, seal area, and finish notes. A mylar bag proof is a digital representation of the planned design, so it should be read with the construction details attached.
| Proof area | Check this | Decision |
|---|---|---|
| Front panel | Logo, product name, variant, window, hierarchy | Whether the closed bag reads correctly |
| Back and sides | Instructions, barcode area, seams, copy direction | Whether the filled bag remains readable |
| Opening and seal | Zipper, heat-seal space, tear feature, hand position | Whether the opening matches the pack-out |
| Finish and window | Matte, gloss, foil, spot UV, window boundary | Whether the visual treatment fits the layout |
Which mylar bag formats can use a 3D preview?
Custom mylar ziplock bags can use a preview to check the closure and top panel together. Die-cut mylar bags need the custom outline and artwork boundary. Large mylar bags need a clear view of changed front and side proportions. Mylar bags for freeze drying can use a preview to clarify the fill format and panel layout.
Can the mockup show finish and window choices?
The mockup can show the intended artwork placement, visual direction, and window boundary. Finish notes still have to be specific because matte, gloss, soft-touch, foil, embossing, debossing, spot UV, and holographic treatments do not read the same way on a screen. Mark the window area and state whether it must remain clear of copy, seams, and closure features.
What should you send for a mylar bag design preview?
Send the product, bag style, finished dimensions, artwork, brand assets, copy, closure, window request, finish direction, destination, and quantity. If the artwork is not ready, free design support can organize the panel hierarchy and starting direction. A dieline is the flat cutting template used to cut the bag shape and place the artwork.
Use custom packaging design to organize the dieline and proof conversation. The MOQ is 100 units. Pricing is from $0.49 per unit at volume, quoted to spec. Production is typically 8 to 10 business days after proof approval, plus delivery. Free US shipping and free design support are available. Order the $19.99 sample kit when a physical bag surface reference would help.
Frequently Asked Questions
How is a 3D mockup different from a physical mylar bag sample?
A 3D mylar bag mockup checks artwork placement, panel orientation, shape, seams, opening, and construction notes on screen. A physical sample gives a tangible reference for the bag surface and finish direction. The $19.99 sample kit is the physical option, while the free digital proof handles the design review.
When does production begin after a mylar bag proof?
Mylar bag production is typically 8 to 10 business days after proof approval, plus delivery. The proof must identify the selected format, finished size, artwork, closure, window, and finish before approval. The production period starts after that approval, so the proof review belongs in the order plan.
Can artwork change before proof approval?
Artwork can change during the proof stage before approval. Send corrections to copy, logo placement, colors, window position, closure, or finish notes while the design is under review. Custom Packaging Lane can update the digital direction so production uses the approved artwork and construction.
Which bag features should appear in the 3D preview?
A 3D mylar bag preview should show the bag outline, front and back panels, seams, opening, closure, window boundary, major print areas, and finish direction. Send the actual format and dimensions so the preview reflects the intended bag rather than a substitute shape.
What does the Custom Packaging Lane mockup request cost?
Custom Packaging Lane provides free design support, a free digital proof, and a free 3D mylar bag mockup process. Custom orders start at 100 units, with pricing from $0.49 per unit at volume, quoted to spec. Free US shipping and the $19.99 sample kit are available.
