When a sample test is useful
Use a sample trial to resolve product-handling or sealing questions and compare candidate routes on your production material. We agree the configuration, measurements and sample quantity before the run.
- Sticky, dusty, fragile or poorly flowing products, including powder stick pack and sachet applications
- Liquids with particles, high viscosity or foaming, such as liquid and sauce portion packs or pesto and oil-suspension pastes
- A new film, laminate or pouch that has not been run before
- A tight fill tolerance or a very small dose
- A choice between two packaging routes or dosing methods
Agree on samples before shipping
Discuss representative product and packaging samples, handling conditions and the quantity needed. Confirm shipping instructions with our engineering team before sending material to our Foshan factory.
- Product from a normal production batch, in the agreed quantity
- Packaging material in the production specification: roll film at the correct width, printed if registration matters, or pouches, cartons or labels
- A safety data sheet for chemical, flammable or otherwise hazardous products
- Storage conditions, such as frozen, chilled or dry, and how long the product stays stable
- Your reference ID on the parcel and in the shipping documents
Define what the trial should establish
Agree on the proposed configuration and the measurements that will help answer your selection questions.
- Fill consistency and measurement method
- Pack formation and seal evaluation
- Product behavior during feeding and dosing
- Output, stoppages and reject handling under the recorded conditions
Agree how results are measured
State before the test how each result will be judged. For fill, agree how many packs are weighed and against which target and tolerance. For seals, agree whether packs are checked visually, by hand or by a leak or drop check you specify. For output, agree whether the figure is packs formed or good packs over a timed run.
Agree what you receive
Decide in advance what the test should produce for you: a written record, photographs or video of the run, and whether packed samples are returned for your own checks. Returning samples may involve shipping cost and handling conditions to agree.
Keep conditions with the result
We record the product batch, packaging material, machine configuration, settings and observations together. These conditions make the findings useful for selecting tooling and planning acceptance checks.
Turn trial findings into an acceptance plan
Use the trial results to finalize the dosing, forming and sealing arrangement. Set the production-run duration, format coverage and batch variation to evaluate in the acceptance plan. Shelf-life studies and tests of downstream units need their own methods and conditions.
What to send us
Send what you have and mark what is still undecided. Discuss your application with LINEVO.
| Item | Why we need it | Example format |
|---|---|---|
| Product and its behavior | Powder, granule, liquid, paste or solid pieces decide the dosing method and the parts that touch the product. | Free-flowing granules, with a photo of the product |
| Finished pack and fill | The pack style, its size and the fill per pack set the format and the dosing range. | Pillow bag, 100 × 150 mm, 50 g per bag |
| Target output | Output per minute or per shift decides the number of lanes and the model size. | 60 good packs per minute, one shift per day |
| Packaging material | Film or container type affects sealing, forming and the settings we confirm. | Laminated roll film, 250 mm wide, or the film datasheet |
| Site and destination | Power supply, compressed air and destination country decide the electrical and utility scope. | 380 V, 3-phase, 50 Hz, delivery to Germany |
