A buyer searching for Soft Tube 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 Soft Tube. 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 Soft Tube
Packaging is specified by the product it must protect, the distribution test, and the print. For a Soft Tube, 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.
Soft Tube is easy to confuse with Blister Pack. 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 Soft Tube |
|---|---|
| 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. |
| Barrier | Moisture or grease needs, if any. |
How to compare two offers
Lay both quotes for Soft Tube on one sheet and line up print, closure, and recycling. 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 Soft Tube with a cheaper line that omitted print.
Documents worth having before the deposit
Ask for a drawing with flute or film and the dieline. The file should name Soft Tube 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
- Sizing the box to the product and forgetting void and drop height.
- Approving artwork without the barcode quiet zone.
- Claiming a recycle mark the local system does not accept.
On a Soft Tube, 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: “Soft Tube — 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 automotive grade belong
Searches often add a constraint to Soft Tube: automotive grade, or waterproof / IP65. Keep those on this page. Automotive grade is a temperature, vibration, and documentation claim. Ask which AEC or customer spec is actually met, and for which part number. IP65 in IEC 60529 means dust-tight and protected against water jets. Write that code if hoses are the real exposure. The word waterproof alone does not name a test. 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 Soft Tube include?
Write size, board or film, strength test, and artwork revision.
Is a cheaper Soft Tube the same part?
Only if print, closure, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Soft Tube they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
