Choose with evidence. Test in your process.
Use your contents, equipment and performance targets to define a practical film evaluation.
Four inputs that shape the specification.
Contents & contact
Describe the liquid, powder, granules or contact material. Share relevant composition, moisture and contact duration.
Equipment & process
Specify forming depth, sealing method, running conditions and any current film reference.
Use & removal
State the target water temperature, agitation and intended dissolution or removal conditions.
Storage & handling
Describe storage duration, humidity exposure, pack format and how the material is handled after opening.
A clear specification makes samples more useful.
Film dimensions
Thickness, width, roll length and any agreed tolerances.
Roll configuration
Core internal diameter, maximum roll diameter and winding requirements.
Appearance & finish
Clear or colored material; smooth or embossed surface where available.
Processing requirements
Forming, sealing, wrapping, shrink processing or conversion requirements.
Dissolution conditions
Water temperature, agitation, sample size and the endpoint you want to evaluate.
Finished products
Bag dimensions, seam construction, cover shape and packaging requirements.
Compare the film under repeatable conditions.
01 / Record the baseline
Identify the sample grade, thickness, batch reference and conditioning history before comparing results.
02 / Check contact behavior
Evaluate the selected film with the actual contents or contact material under representative storage conditions.
03 / Run the process trial
Observe forming, sealing, release or other relevant process behavior on your equipment.
04 / Agree acceptance criteria
Record results and agree the required performance and final dimensions before confirming the order.
Record the conditions, not just the time.
For a useful comparison, record film thickness, sample dimensions, water volume, temperature and agitation. Define whether your endpoint is initial breakup, loss of visible film or another agreed observation.
Use the same method for all samples. These observations describe the test performed; they are not a biodegradation or environmental certification.
Request information for the selected grade.
Storage & handling
Request the instructions for unopened rolls, opened material and finished products.
Sample review
Send your current specification, test conditions and observations for discussion.
Before you set a numerical target.
Can I use one dissolution time for every film?
Use a target tied to your selected grade and test method. Thickness, temperature and agitation must be stated alongside the result.
Can you confirm compatibility from the product name alone?
The product name is a starting point. Actual contents, contact conditions and sample evaluation are needed to assess suitability.
Which machine details should I share for pod film?
Tell us whether the machine is rotary drum, flatbed or another type, and include forming depth, sealing conditions and the current film specification.
Are all custom options available for every product?
Available dimensions, finishes and conversion options depend on the product. Confirm the combination you need before ordering.
Bring us your current specification.
