Construction choices that still block a quote

shrink bags bulk

Before a shrink bags bulk request can share one factory line, open choices on film family, post-consumer recycled content, bag form and decoration have to be named or marked undecided. This page is a material-options brief, not a sustainability scorecard and not a claim that we extrude film or own a converting plant.

Decision order for a comparable construction

  1. Name the film story

    POF, PE, PVC or PETG. Post-consumer recycled content is a lot file, not a site slogan.

  2. Pick a bag form

    Pre-made bag, centerfold roll or sleeve. Do not average those tools on one bulk-order row.

  3. Lock gauge and shrink ratio

    50-80 μm POF or a thicker PE wall, plus the shrink ratio the tunnel can actually run.

  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 resin versus virgin POF

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

Check: lot file, not homepage badge

Mono-material PE versus multilayer barrier

A PE or PP mono-material story can improve recycling reporting when the bag stays in the same family. A metallized or EVOH barrier layer is a new construction. Verify the buyer still accepts that barrier before treating the quote as the same shrink bags bulk line. Mono-material first can help reporting; barrier when shelf life requires it can still need a laminate.

Check: barrier family together

Paper-plastic or fibre substitutes

A paper-plastic or fibre alternative is a different pack family. If a factory offers a kraft pouch or a folding carton instead of a shrink bag, treat it as a new RFQ. Do not score it as a shrink bags bulk saving. Paperboard caliper belongs on that other brief, not on this one.

Check: same family before compare

Files that support an option, not logos of allies

Food-contact and migration testing

If the bag touches food, ask for the FDA 21 CFR review path on that film and ink lot. A missing file is a reason to keep the quote pending, not a reason to advertise a green claim. Seal initiation temperature only belongs on the brief if a heat-seal path is part of the same purchase.

Recycled-content notes

Global Recycled Standard language, if used, must match the resin 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

60 μm

Example POF gauge. Only valid with bag size and shrink ratio named on the same line.

50%

Example shrink ratio used on many tunnel briefs. Do not convert it into a PE duty without labeling the film.

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 shrink path, or accept a refit. Confirm the 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.

Mark undecided films or bag forms instead of forcing a fake complete spec. Factories can quote a range or decline.
