BAG FORMAT
Zip-seal bags.
Start with the use.
Repair kits or components where repeated access is part of the handling process.
Concept illustration only — not a measured product or load-rating demonstration.
What to discuss
Check the usable space below the press seal and access around the part. Reclosability is not a waterproof, airtight or anti-corrosion claim.
- Parts per set and their arrangement
- Usable space below the closure
- Expected opening and closing needs
- Part edges and any direct oil contact
- Common materials discussed
- LDPE · LLDPE · PO (Polyolefin) · PP are discussed across projects; material structure and suitability for this bag format are confirmed per project.
- Dimensions & thickness
- Confirmed by project — no universal range is promised.
- Bring the artwork or reference for review.
- Sampling
- Available; scope, timing and costs agreed individually.
Where this format can fit
A press-to-close opening can help when a service kit or component is handled more than once. It is a handling feature, not evidence of airtight, waterproof or corrosion-protection performance.
Packaging risks to review
- The closure consumes usable space and can interfere with a bulky part.
- Sharp or contaminated edges can affect repeated opening and closing.
- Powder, oil or grit near the seal can change how it behaves.
- A reclosable bag can still permit moisture or air exchange.
Questions to settle in the brief
- Parts per set and their arrangement
- Usable space below the closure
- Expected opening and closing needs
- Part edges and any direct oil contact
Sample checks before approval
A sample is useful only when it tests the real part and the intended handling method. Record what passed, what failed and what remains open.
- Place the complete kit below the closure and test access.
- Open and close the sample repeatedly with the real contents.
- Check the seal area for trapped parts or sharp contact.
- State any barrier, cleanliness or corrosion requirement for separate review.
Material, thickness and opening
LDPE, LLDPE, PO (polyolefin) and PP are discussed across projects. Their suitability for this format, the film structure and the usable opening are confirmed per project. Closure strength, barrier performance and expected reopen cycles are confirmed by project. No standard cycle count or protection claim is made.
Print and identification
Bring the artwork or a reference. Keep part number, quantity, batch or handling text in a layout that remains visible after filling. Print feasibility, color and approval method need factory review.
What remains a project decision
Dimensions, thickness, closure, print and performance are not fixed by the format name. Sampling is available; scope, timing and cost are agreed individually. Production timing and pricing remain subject to quotation.
How to brief this format
Start with the packed part: its largest outline, number of pieces and any edge or surface that must stay clear. Say how the pack is filled, closed, carried and opened. If a current bag is used, send its measured dimensions and identify what should stay the same; do not send only a product name.
For print, separate the information that must remain readable from decoration. Part number, quantity, handling notes and barcodes can have different space and contrast needs. At sample stage, check that the opening and closure still work after the label is applied, then keep the approved sample reference with the artwork version.
What a concept image cannot show
The illustration on this page explains the format; it is not a measured product, a material sample or a load test. Film thickness, seal condition and opening behavior need a physical sample with the real component. A successful fit does not establish transit protection, barrier performance or a production release.
