What this application reference can establish
Evidence level B — application reference. The source text raises dosing, seal integrity, local adaptation and string-and-tag placement for a Colombian tea line. It presents later performance and cooperation as fact without publishing test sheets or commissioning records.
The title and retained images orient the Colombia double-chamber folding review toward double-chamber folds, thread tags and dose distribution.
For the Colombia double-chamber folding review, archived transaction and outcome language remains outside acceptance for double-chamber folds.
Test double-chamber folds with production samples
A double-chamber bag divides the dose through folds and web movement, so tea particle size affects both feeding and final distribution. Include fines and long fragments that can sit across a fold or migrate toward the top closure.
For A double-chamber bag divides the dose through folds and web, record sample origin, storage and expected variation.
Release its operating window only when the trial can prove chamber folding, dose containment and string-tag placement together rather than judging only the final bag outline.

Freeze the package boundary for thread tags
Freeze filter-paper permeability, heat-seal coating, chamber dimensions, thread length, tag stock and staple or knot method where applicable. Each item influences brewing behaviour and mechanical timing.
Record the material code for thread tags.
Add its dimensions and seal zone to the signed drawing.
Test each substitution against look for uneven product split between chambers.
Review each handoff affecting thread tags
Review metering, web folding, chamber division, thread and tag application, top closure, cutting and counting as linked operations. A correct dose can still produce an unusable bag if the fold or thread station drifts.
Look for uneven product split between chambers, trapped particles at the closure, loose tags and thread positioned across the seal. These defects need separate counters because one adjustment may improve a fold while worsening dose distribution.

Release matrix for double-chamber folds, thread tags and dose distribution
| Decision area | Case-specific observation | Required action |
|---|---|---|
| Evidence | The source text raises dosing, seal integrity, local adaptation and string-and-tag placement for a Colombian tea line. | Keep customer and outcome claims outside approval. |
| Product | A double-chamber bag divides the dose through folds and web movement, so tea particle size affects both feeding and final distribution. | Use production-representative samples and record variation. |
| Package | Freeze filter-paper permeability, heat-seal coating, chamber dimensions, thread length, tag stock and staple or knot method where applicable. | Freeze drawing, material code and retained sample. |
| Main risk | Look for uneven product split between chambers, trapped particles at the closure, loose tags and thread positioned across the seal. | Turn the risk into a visible reject and test criterion. |
| Release gate | Prove chamber folding, dose containment and string-tag placement together rather than judging only the final bag outline. | Sign the evidence record before commercial release. |
Keep phase-labelled evidence for thread tags
Sample packs across startup, stable running, reel splice and restart. Open the bag carefully to assess chamber distribution, then test thread pull, infusion opening, net content and visible seal contamination.
For double-chamber folds, thread tags and dose distribution, keep samples, consumable lots, settings and rejects in time order.
Evidence must cover look for uneven product split between chambers after an interruption and restart.
Measure the site inputs in Colombia
For Colombia, record the actual installation altitude, room humidity, voltage, frequency and available technical support rather than assume national defaults. Packaging artwork and food-contact acceptance must follow the buyer's documented review.
Assign a named owner in Colombia to every measured input for double-chamber folds, thread tags and dose distribution.
At the Colombia site, use actual room conditions, utilities and local review for double-chamber folds.

Leave a repeatable record for dose distribution
The handover pack should contain fold diagrams, thread-path settings, approved filter references, reject photographs and spare parts for the closure station. Operators need a response plan for dose drift versus mechanical fold drift.
Version the setup that releases double-chamber folds, thread tags and dose distribution.
A future SKU outside dose distribution receives its own sample record and re-test.
Questions to close before approval
What preserves dose distribution after handover?
Keep double-chamber folds, thread tags and dose distribution beside retained packs, reject examples, training records, critical spares and open actions.
What must the trial prove about look for uneven product split between chambers?
Run production samples around look for uneven product split between chambers. Keep interventions and open actions beside evidence for double-chamber folds, thread tags and dose distribution.
Can the Colombia double-chamber folding review be treated as a completed project?
No cited order or signed acceptance appears in the Colombia double-chamber folding review archive. Decide double-chamber folds from current samples.
Which thread tags input is frozen before tooling?
The release scope is to prove chamber folding, dose containment and string-tag placement together rather than judging only the final bag outline. Any change affecting thread tags requires a recorded re-test.
Conclusion
Move this application forward only when double-chamber folds, thread tags and dose distribution agrees with measured site inputs and retained samples.
Use the related Double Chamber Tea Bag Machine range as a configuration reference for double-chamber folds. Build current acceptance around thread tags and look for uneven product split between chambers; keep the archived outcome outside approval.
