A buyer searching for Shrink Film is usually trying to stop a bad substitute. Packaging is specified by the product it must protect, the distribution test, and the print. The notes below are selection criteria for a Shrink Film. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Shrink Film
Packaging is specified by the product it must protect, the distribution test, and the print. For a Shrink Film, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Shrink Film is easy to confuse with Clamshell Packaging. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Shrink Film |
|---|---|
| Barrier | Moisture or grease needs, if any. |
| Colors, the artwork revision, and the barcode. | |
| Closure | Tape, adhesive, or a zipper, and how the line erects it. |
| Recycling | The material claim you are prepared to print. |
| Size | Internal dimensions and the board or film grade. |
| Strength | ECT, burst, or a stated drop and stack test. |
How to compare two offers
Lay both quotes for Shrink Film on one sheet and line up barrier, print, and closure. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Shrink Film with a cheaper line that omitted barrier.
Documents worth having before the deposit
Ask for a drawing with flute or film and the dieline. The file should name Shrink Film and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Approving artwork without the barcode quiet zone.
- Claiming a recycle mark the local system does not accept.
- Sizing the box to the product and forgetting void and drop height.
On a Shrink Film, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Shrink Film — Write size, board or film, strength test, and artwork revision.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like explosion-proof / ATEX belong
Searches often add a constraint to Shrink Film: explosion-proof / ATEX, or automotive grade. Keep those on this page. ATEX or IECEx is a certificate for a zone, a gas or dust group, and a temperature class. An IP rating does not grant it. Skip the mark if the site is not hazardous. Automotive grade is a temperature, vibration, and documentation claim. Ask which AEC or customer spec is actually met, and for which part number. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Shrink Film include?
Write size, board or film, strength test, and artwork revision.
Is a cheaper Shrink Film the same part?
Only if barrier, print, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Shrink Film they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
