Construction choices that still block a quote

kraft paper bags with logo

Before a kraft paper bags with logo request can share one factory line, open choices on paper grade, post-consumer recycled content, window film and decoration have to be named or marked undecided. This page is a material-options brief for PCR, mono-material and paper-plastic substitutes. It is not a sustainability scorecard and not a claim that we pulp fibre or own a converting plant.

Decision order for a comparable construction

  1. Name the paper story

    Virgin kraft, recycled kraft or a stated post-consumer recycled content share. PCR is a lot file, not a site slogan.

  2. Decide the window path

    No window, paper-only die-cut, or a PET / PP / PLA / cellulose patch. Do not average those tools on one logo-order row.

  3. Lock GSM and die line

    70–120 g/m² plus window placement from the top seal. A moved patch is a new die line even when the logo stays put.

  4. Choose decoration route

    Digital for frequent artwork changes; flexographic printing or gravure printing for a stable volume. Record the open dispute instead of hiding it.

Option cards a buyer can verify

PCR kraft versus virgin fibre

Post-consumer recycled content can support a recycling report when the lot file names the share. It can also change shade, tear and food-contact status. Accept an alternative only after the buyer checks color and the food-contact file, if the fill needs one.

Check: lot file, not homepage badge

Mono-material paper versus a film window

A paper-only opening can improve recycling reporting when the bag stays in the fibre family. A PET or PP patch is a paper-plastic assembly. Verify the buyer still accepts that mixed construction before treating the quote as the same kraft paper bags with logo line. Mono-material first can help reporting; a sealed window when product visibility requires it can still need a film.

Check: film family together

Paper-plastic or fibre substitutes

A PLA window, a cellulose window or a folding-carton sleeve is a different pack family. If a factory offers a stand-up pouch or a carton instead of a kraft bag, treat it as a new RFQ. Do not score it as a kraft paper bags with logo saving. Oxygen transmission rate belongs on that other brief when the substitute is a sealed pouch.

Check: same family before compare

Files that support an option, not logos of allies

Food-contact and migration testing

If the bag or window film touches food, ask for the FDA 21 CFR review path on that paper, film and ink lot. A missing file is a reason to keep the quote pending, not a reason to advertise a green claim. Water vapor transmission rate only belongs on the brief if incoming QC will test that film lot.

Recycled-content and fibre notes

FSC or recycled-content language, if used, must match the named paper lot. Neither document is granted by publishing this page. Digital for short runs can reduce plate cost when SKU count is high; conventional flexo or gravure often keeps unit cost and spot color control better on a stable long run.

Numbers that belong on the brief

80 g/m²

Example kraft GSM. Only valid with bag size and window placement named on the same line.

80 × 50 mm

Example window opening. Do not convert it into a PLA duty without labeling the film family.

4-color

Example flexographic printing or gravure printing count. Digital short runs still need artwork revision written beside it.

What must be verified before accepting an alternative

Confirm the alternative uses the same bag size unit and handle path, or accept a refit. Confirm the window film family is the one you asked for. Confirm print route and plate extras are itemized. Confirm any recycled or food-contact statement is a file for that lot. If those items stay open, the alternative is not yet comparable. Continue with inquiry options or the requirement form.

Lock the open material choices

Send paper grade, window path and logo process so factory replies can share one construction. No existing quotation is required.
