Kraft paper sack
Paper-based construction; may use multiple plies and, where required, a suitable liner or barrier. Confirm strength, moisture needs and food-contact suitability with the supplier.

Two common sack directions, made easier to compare
Start with the physical package, then explore how the materials and artwork work together. These Briandcas-branded visuals are illustrative concepts, not approved production specifications.
Woven polypropylene sack
Woven fabric provides strength; optional lamination or an inner liner may be considered for print quality or additional moisture management. Validate the full structure and seals.
Important: printed branding in these concept images is an approximation. Use the official Briandcas SVG logo in final artwork, and have the packaging converter confirm dimensions, seams, material layers and print template before production.

Paper Bags, Wraps & Sleeves
Explained.
Paper formats used for carrying, wrapping, grouping and presenting products, from simple bags to printed sleeves. Paper bags, wraps and sleeves cover a wide range of constructions. A shopping bag, bakery wrap and product sleeve do not share the same strength or barrier requirements. Paper grade, fibre direction, handle or seam design, coatings, adhesives and exposure to grease or moisture all affect suitability.
Schematic only; not to scale. Final material construction, dimensions, seals, closures and print zones must come from the selected packaging converter.
01 / Anatomy & construction
What is this format?
Paper bags, wraps and sleeves cover a wide range of constructions. A shopping bag, bakery wrap and product sleeve do not share the same strength or barrier requirements. Paper grade, fibre direction, handle or seam design, coatings, adhesives and exposure to grease or moisture all affect suitability.
Key components
- Main print face
The primary visible panel; consider how the bag is held, folded or displayed. - Side gusset / fold
Creates capacity and changes how the artwork appears when the bag is filled. - Bottom fold / seam
Carries the contents and should be considered in the structural drawing. - Handle / reinforcement
If present, affects load distribution, print clearance and assembly. - Sleeve overlap / adhesive area
A sleeve must wrap the product and leave enough area for glue or mechanical retention.
Design principle: build the artwork around the real pack construction, not the other way around. Folds, seals, fitments and machine requirements can change the printable area.
02 / Materials & structure
What is it made from?
Common component roles are described below for learning. They are not a recommended bill of materials for every product or supplier.
| Component / layer | Typical role and specification questions |
|---|---|
| Paper grade | Selected for stiffness, surface, strength, absorbency and print performance. |
| Coating / barrier if used | May address specific grease or moisture needs; compatibility and recovery claims must be assessed. |
| Ink / adhesive | Must suit the paper, intended use and converting method. |
Important: a pack’s performance depends on the complete converted structure, including seams, folds, seals, fitments, thickness, process settings and storage conditions. Ask the converter for supporting technical data and product-specific validation.
03 / Applications & trade-offsPROTECTION PRODUCTION USE & DISTRIBUTION
Where is it used?
Retail carry bags, bakery and takeaway wraps, product sleeves, promotional packaging and secondary presentation applications when the selected grade is appropriate.
Potential advantages
Tactile paper appearance; printable surface; flexible sizes and shapes; can be supplied flat for storage.
Trade-offs to consider
Paper strength and barrier vary; grease or moisture may affect performance; handles and seams can fail if under-specified.
Define the product’s sensitivity to moisture, oxygen, light, aroma, contamination, impact or leakage where relevant.
Confirm filling equipment, speed, sealing method, machine compatibility, pack orientation and expected production volume.
Consider transport, stacking, shelf presentation, opening, carrying, reclosure and local end-of-life realities.
04 / Artwork & prepress
Designing for the real pack
Request a structural drawing and sample if folds, handles or sleeve overlaps affect the design. Keep important copy away from seams, adhesive zones, folds and handle cut-outs.
Pre-production checklist
- Define the carried product, load and intended use.
- Confirm paper grade, finish and any coating or barrier.
- Obtain dimensions and approved structural artwork template.
- Check handle, seam, glue and fold zones.
- Test with the real product and realistic handling conditions.
Artwork handover: request the approved dieline or panel drawing, print specifications, colour guidance, technical layer instructions and proofing procedure from the supplier. Never assume a generic template is production-ready.

Frequently asked questions
Are all paper bags suitable for food?
No. The complete material, inks/coatings where relevant and intended contact conditions must be suitable.
Can a paper wrap replace a barrier pack?
Only if the product and distribution requirements can be met. Paper alone may not provide the required moisture, grease or oxygen protection.
Can a sleeve hold a product by itself?
Some sleeves are only presentation components and rely on an inner pack or product geometry; confirm the intended structural role.
