BAG FORMAT
Easy-tear bags.
Start with the use.
Packs where an agreed tear feature helps the recipient access a part.
Concept illustration only — not a measured product or load-rating demonstration.
What to discuss
The exact tear structure, location and opening behavior need sample discussion. Do not assume a tear strip, perforation or a universal tear strength.
- Where the pack should open
- Current opening problem, if any
- Part clearance from the proposed tear area
- Packing, closing and handling sequence
- 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
An easy-tear feature can be considered when the recipient needs a straightforward opening without tools. The exact tear location and behavior must be demonstrated on a sample rather than inferred from the format name.
Packaging risks to review
- A tear path can cross a printed instruction or part reference.
- A sharp component can contact the intended opening zone.
- Tear behavior can change with film direction, thickness and the filled shape.
- Premature opening can expose the part during transit.
Questions to settle in the brief
- Where the pack should open
- Current opening problem, if any
- Part clearance from the proposed tear area
- Packing, closing and handling sequence
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.
- Mark the intended opening direction and location on a drawing.
- Test opening with the actual filled pack, not an empty bag.
- Check that the part remains enclosed during normal handling.
- Confirm print and label visibility after the pack is opened.
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. Tear strip, perforation, laser score or another construction is not assumed. The opening method, force and location are confirmed per project.
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.
