Custom Zipper Bubble Bags for Shipping: OEM Design and Printing Options

Not all pouches close when filled, even when the design matches the drawing. At GT GROUP, artwork approval comes after the packaging specifications.

Zipper Bubble Bags for Shipping

These bags are made from flexible polyethylene film with heat-sealed edges, and have a resealable zipper closure.

Bubble wraps help prevent minor impacts and abrasions. For edge protection, additional rigid dock protection may be needed. To fully close the pouch, the zipper must be closed completely.

1. OEM Dimensions: Specify Usable Cavity

The options for the product are 20 x 30 cm and 30 x 40 cm and these represent the bag dimensions. The internal dimensions are clear. When requesting a quote for a custom Zipper Bubble Bag for Shipping, specify:

Design Variable	Technical Specification	Why It Matters
Dimensions	Measurement reference points	Sets the converting target
Internal opening	Clear width below side seals and zipper track	Determines insertion clearance
Product profile	Maximum packed thickness and protruding corners	Prevents seam/zipper loading
Seal and zipper location	Width and offset of seal and zipper, opening direction	Controls access and available volume

Check side seals and seals for proper tension after product is sealed.

2. Gauge and Bubble Geometry

•Gauge: Determine the likelihood of film rupture and exposure.

•Bubble Structure: Determine the ability of bubble structure to retain air, and how air is compacted. Smaller bubble cells may deflect better and require less clearance.

•Zipper and Seals: Are zippers engaged or loaded in a bag?

ESD protection is generally not needed for standard PE films. For heavier products a rigid additional insert or pack may be necessary.

3. Printing Options for Custom Zipper Bubble Bags for Shipping

There may be lines that need to be extremely thin. Other considerations may be clearances, folding and/or welding. PE Surface treatments and conversions can affect the adhesion of the ink to the PE surface. Other factors that affect adhesion include the treatment of the surface and the ink.

Printing Method	Typical Application	Preproduction Consideration
Flexographic	Repeated logos and line graphics	Plate cost, minimum line width, color consistency
Gravure	High-volume detailed graphics	Cylinder preparation, print registration
Digital	Selected prototypes or shorter runs	PE compatibility, ink adhesion, unit cost

Surface printing leaves graphics exposed to rubbing. Reverse printing places ink behind a transparent layer and generally requires a suitable laminate.

Confirm method availability for the selected pouch.

4. Manufacturing Precision: Which Numbers Should Be Measured?

GT GROUP has 13 units of production equipment and five units of high-speed envelope production lines across its facilities. The description includes film blowing, laminating, slitting, printing, bag conversion and quality testing.

These facility-specific numbers don't establish any capacity or tolerance for this SKU.

Agree to the measurement criteria for inspection prior to sample sign-off for Zipper Bubble Bags for Shipping. The measurement criteria may include:

•Dimension Deviation: Completed width and length. Usable opening compared to approved drawing.

•Film Gauge: Measurement at specified positions compared to nominal.

•Print Registration: Color to color registration, and alignment from cut/seal line.

•Seal Strength: Peel test specimen of defined nominal width, defined peel test method, and pass/fail criterion.

•Zipper Function: Continuity of closure and behavior during opening and closing after defined number of cycles.

No fixed tolerances are provided for this SKU, agree to acceptance ranges for design.

5. From Artwork to Approved Production Sample

Our process includes requirement, quotation, sample approval and production.

Buyers must supply the following:

•PDF or vector artwork with color references.

•Packaged product dimensions and weight.

•What type of cushioning and zipper is required.

•Product will be shipped under what conditions and how many.

Assessments of graphic fit and zipper function should also be included in the approval process. Empty pouches are not shipping ready.

6. Testing and Landed Cost Decisions

Finished samples of Zipper Bubble Bags should be filled to their final representation and then tested.

Test packaged shipping for edge seal peeling and ink rub off. Separate bags with zippers and analyze package deformation.

Using film properties to certify packaged shipping is not allowed. For ISTA testing the bag must be fully filled.

The total cost of shipping the final package must include:

The cost of the bag + the cost of the setup/tooling + the cost of secondary packaging + the cost of labor + freight + the cost of exposure to damage.

Using a smaller pouch to decrease landed cost may in fact increase landed cost due to increases in returns caused by closure strain.

7. Reuse, Recycling, and Supplier Selection

Bubble retention and the durability of the seams determine reusability. Recyclability of the package depends on the complete structure, and the local collection and recycling infrastructure.

Ask suppliers for samples based on your dimensional requirements, written acceptance criteria, approved artwork, and batch traceability.

GT GROUP supports sample based, custom artwork changes and offers ODM services.

Frequently Asked Questions

Are Zipper Bubble Bags for Shipping able to have a custom logo?

Yes. Artwork can be submitted for print area, colors and substrate, if compatible.

What files should buyers send?

Start with a vector artwork or print ready PDF. Final prepress requirements may vary, but we will communicate them to you.

How do I choose the bag size?

Measure the packed product, and then determine the usable dimensions, accounting for zipper and side-seal allowances.

Are these bags waterproof or ESD-safe?

Do not assume either claim; request product-specific tests or a suitable protective construction.
