Start with the actual carton and applicator
“Corrugated carton” describes the package, not the exact surface receiving the adhesive. An uncoated board, a printed area and a film-coated area should not be treated as the same bond. Before requesting a glue-stick sample, identify both surfaces being joined and the equipment that will apply the adhesive.
Jiajian's HT-4403 product page presents the model as an option for uncoated corrugated cartons. Its model-specific technical data sheet lists packaging among the intended uses. Those sources establish a candidate for review; they do not establish a passing carton test, a particular customer's result or suitability for every coating, machine or destination.
1. Describe the board rather than asking for “carton glue”
Send representative samples of the production board and identify the exact glue line. Record whether each bonding surface is bare paper, printed, varnished, laminated or otherwise treated. Include flap construction, board grade if known, dust or recycled-fiber variation, and any change between the sample board and the volume-production board.
The HT-4403 page's uncoated-carton positioning should not be extended to a UV-varnished or film-laminated carton without a separate review. If the bonding area has a coating, tell the supplier before choosing a sample. The glue-stick product range lists different packaging candidates, but their descriptions are not interchangeable test results.
2. Check the feed format and the current technical sheet
The current HT-4403 product page lists 7 × 270 mm and 11 × 270 mm stick formats. The model-specific sheet revised March 18, 2025 identifies a yellow EVA glue stick and a recommended application-temperature range of 150–180°C; it does not list those stick dimensions. Confirm the exact orderable diameter and length with sales and compare them with the applicator manufacturer's permitted feed dimensions before requesting a sample.
The same sheet lists a 45-second opening-time reference and an 8–15-second curing-time reference. It does not define the test methods or prove that a particular carton line can run at a particular speed. Ask the technical team to explain the measurement conditions and agree a safe trial window within the equipment's operating limits. Do not copy the sheet's temperature or timing entries directly into a machine recipe.
3. Design a small, recorded line trial
Before the trial, let the packaging and production teams agree how a pass will be judged. A useful record includes:
- Adhesive model, sample identifier and technical-sheet revision.
- Carton board and the exact two surfaces joined at each glue line.
- Applicator make and model, verified stick dimensions and measured working temperature.
- Bead placement, amount applied, compression or closing conditions and production speed.
- Bond appearance and the buyer's agreed checks after normal handling, packing and relevant storage or transport conditions.
- Any changes made during the trial, with failed samples retained alongside passing ones.
These are proposed buyer controls, not HT-4403 laboratory results or a promise of performance. If several carton constructions are used, test each relevant construction. A hand-applied sample should not be treated as approval for a different automated station.
4. Request the documents for the actual order
Ask for the current HT-4403 technical sheet and identify the destination market and end use. A report about a general yellow hot-melt material is not, by itself, proof of HT-4403-specific certification or finished-package compliance. Any requested regulatory or customer-standard document must be checked for model, tested material, report date and scope before it is used as an approval claim.
Availability, price, minimum order quantity, lead time and final packaging should be confirmed for the proposed quantity and destination. None is established by the sample-trial checklist.
A short sample request buyers can use
> We seal [carton construction] at [glue-line location]. The two bonding surfaces are [surface A] and [surface B], with [print, varnish or film details]. Our stick-fed applicator is [make/model] and accepts [diameter × length]. We currently run at [measured temperature and line speed]. Please confirm whether HT-4403 is an appropriate sample candidate, the available stick size, the current technical-sheet revision and a proposed trial scope. Our destination is [country/region] and estimated purchasing volume is [quantity and unit].
This brief gives the supplier enough context to screen a sample; it is not a request to guarantee a bond before the line trial.
Frequently asked questions
Does HT-4403 automatically work on UV-coated or laminated cartons?
No such result is established by the sources used here. The product page positions HT-4403 for uncoated corrugated cartons, while the sheet describes packaging use more broadly. A coated bonding surface needs separate product selection and testing.
Can we set the machine to 150–180°C and approve the product?
No. That range is a model-specific technical-sheet reference, not a machine instruction or a carton-performance guarantee. Check the applicator's limits and confirm a trial procedure with the technical team.
Are both 7 mm and 11 mm sticks available for our order?
The product page lists both 7 × 270 mm and 11 × 270 mm formats, but the technical sheet does not state those sizes. Confirm current availability and equipment fit for the exact order before relying on either format.
Does a general yellow-adhesive report certify this model for food packaging?
No. A general material report cannot be treated as model-specific or finished-package evidence. State the intended end use and destination, then have the current documents reviewed for their actual scope.
