Air or water escaping at a seam or a valve.
Seam geometry, welding parameters and valve seating decide whether a chamber holds through a season of use.

Improve an Existing Product
When the sample was good and the production run was not, the answer is usually a specification change rather than a new product. We read the failure, change the construction, and verify the change before it ships.
In-House Film Formulated and calendered on site
24 Hours Holding test on applicable products
AQL 1.5 Pre-shipment inspection
The Situation
Where a Product Starts to Fail
Complaints are rarely about the idea. They are about construction, material, or the drift between one batch and the next.
A film that does not survive the use it was sold for.
Sun, chlorine, abrasion and repeated folding are decided by the film and its formulation, not by the shape.
The first batch was right and the fifth was not.
Print colour, film thickness, accessories and process control drift between runs when nothing holds them.
COMCO Response
Change the Specification, Then Prove It
The levers are known and limited: size, structure, film thickness and configuration.
Diagnosis
Start from the failure, not from the drawing
We look at where and how the product failed: which seam, which chamber, which batch, under what use. That decides whether the fix belongs to geometry, to film, or to process control.
- Failure read against the construction
- Film thickness and formulation checked
- Batch and process records reviewed
The change
Film and construction are ours to change
PVC film is formulated and calendered in-house, so a film change is a production decision rather than a purchase order. Size, structure and film thickness can be adjusted while the external design your retail buyer approved stays as it is.
- Size, structure and film thickness adjustable
- In-house formulation and calendering
- Print and accessories held consistent
Process in action
From Complaint to Revised Production
A revision is sampled and re-tested before it goes back into volume.
-
01
Failure Review
What failed, in which use, and across how many units.
-
02
Specification Review
Seams, geometry, film thickness and configuration re-read against the failure.
-
03
Revised Sample
A counter-sample carrying the change, for approval against the product you sell.
-
04
Validation
Pre-production physical testing, and a 24-hour holding test on applicable inflatables.
-
05
Volume
The revised specification released into repeatable production.
Evidence
How a Change Is Checked
7
Pre-production physical tests
Physical properties are checked on the revised sample before production starts.
24 Hours
Inflation holding
Applicable inflatable products are held under pressure for 24 hours before packing.
AQL 1.5
Pre-shipment inspection
The inspection level applied to pre-shipment checks on the revised specification.
Testing scope depends on the product and the market it is sold into. Where a deviation is confirmed as ours, the affected units are put right — the handling is set out on Quality.

Frequently Asked Questions
Improve an Existing Product FAQ
What buyers ask first about this problem, and how COMCO answers it.
Yes. Send the affected units and the batch information. We review the construction, the film and the production records, then say what changed and what the revised specification should be.
Usually. Size, structure and film thickness can be adjusted inside the same external design, so the look your buyer approved and the packaging that was signed off both stay as they are.
Yes. A revised sample goes through pre-production physical testing, and applicable inflatables are held under pressure for 24 hours. The test set depends on the product and the market it is sold into.
