AUTOMOTIVE APPLICATION

Fasteners & small parts.
Prepare the packed part.

Counted pieces, hardware and mixed sets.

BRING TO THE BRIEF

What the category
cannot tell us.

Check pack quantity and sharp features before choosing an opening or film thickness.

Build an application brief

Useful starting information

  • Count or weight of pieces per bag
  • Pointed threads or edges
  • Counting, identification and repeated access

Film grade, thickness, opening and print layout are reviewed together. If any detail is unknown, leave it for discussion rather than guessing.

How the part family changes the brief

Counted fasteners need a pack that supports accurate counting, containment and identification. Mixed sets need a clear decision on separation before a format is selected.

Packaging risks to review

  • Points and threads can puncture film or catch on the opening.
  • Small pieces can escape through an inadequately closed mouth.
  • Mixed lengths or grades can become difficult to distinguish.
  • Repeated opening can spill or mix the contents.

Information worth sending first

  • Count or weight of pieces per bag
  • Pointed threads or edges
  • Counting, identification and repeated access

Bag format discussion

Start from how the pack is filled, carried, opened and stored. A flat bag, handled bag, zip-seal bag or easy-tear bag may each be discussed, but the format name does not establish dimensions, film or performance. Check pack quantity and sharp features before choosing an opening or film thickness.

Sample and verification checklist

  1. Confirm count by piece or weight and the acceptable tolerance.
  2. Test the real mix for puncture and nesting.
  3. Check that the filled bag can be counted and labeled clearly.
  4. Confirm whether parts may mix or require separate compartments.

What needs project confirmation

Film grade, thickness, usable opening, print layout and special performance are reviewed together. Sampling is available; scope, timing and cost are agreed individually. Production timing and commercial terms remain subject to quotation. Requests for ESD, corrosion, barrier, cleanliness or fluid-contact performance need an explicit technical review.

Preparation questions before an RFQ

Before asking for a price, record the packed outline, the number of pieces in one pack and the condition in which the part arrives. State whether it is dry, oiled or handled with gloves, and whether the pack is opened once or more often. These details change the discussion more than a generic material name.

Keep a photo or drawing tied to the part reference. A vehicle model or catalog image can help identify the component, but it does not replace packed measurements. If a current bag is in use, send its measured dimensions and note what works or fails.

How to compare a sample

Compare samples with the same component and pack quantity. Check the opening, seam, closure and label after filling, then repeat the handling step that matters for the route. Write down the result and keep the sample reference with the artwork version so a later change is not confused with an approved arrangement.

Transit protection remains a separate question. A flexible bag can contain and cover the part, while an outer carton, divider or other support controls movement and external load. Review the complete packing system before treating a bag trial as a transit result.
