Put these on the RFQ for Plastic Bag before you compare prices.

A buyer searching for Plastic Bag 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 Plastic Bag. 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 Plastic Bag

Packaging is specified by the product it must protect, the distribution test, and the print. For a Plastic Bag, 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.

Plastic Bag is easy to confuse with Zip Lock Bag. 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 Plastic Bag
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.
Print Colors, the artwork revision, and the barcode.
Closure Tape, adhesive, or a zipper, and how the line erects it.

How to compare two offers

Lay both quotes for Plastic Bag on one sheet and line up recycling, size, and strength. 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 Plastic Bag with a cheaper line that omitted recycling.

Documents worth having before the deposit

Ask for a drawing with flute or film and the dieline. The file should name Plastic Bag 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 Plastic Bag, 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: “Plastic Bag — 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 waterproof / IP65 belong

Searches often add a constraint to Plastic Bag: waterproof / IP65, or OEM / custom. Keep those on this page. 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. OEM or custom means a drawing, a revision, and a statement of who owns the tool. Without those, you are buying the catalog part. 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 Plastic Bag include?

Write size, board or film, strength test, and artwork revision.

Is a cheaper Plastic Bag the same part?

Only if recycling, size, and the documents match. A missing line is a different offer.

Do waterproof, OEM, or IP words need their own page?

No. For Plastic Bag they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
