Product overview
A pH label does not establish whether a water-soluble film will remain suitable in contact with a chemical. Ingredients, concentration, available moisture, temperature and storage time must be considered together. Sample evaluation is an essential part of specifying this product.
Starting specifications
| Material | PVA / PVOH film |
| Typical thickness | 50–90 μm |
| Product direction | Water-Soluble Film for Acidic and Alkaline Chemicals |
| Dimensions & packing | Width, length, converted dimensions and packing to be discussed for the application. |
| Final selection | Confirmed through representative material and application trials. |
The catalogue specification is a starting point. Ask for the technical information of the proposed grade before setting acceptance criteria.
What to evaluate
- Review complete formulation information and available safety data.
- Record pH, concentration, moisture and contact temperature.
- Evaluate film condition and seal integrity through representative storage.
- Test controlled release under the intended dilution and mixing conditions.
From inquiry to an application trial
Agree a compatibility test with representative contents before conducting a packaging trial. Inspect the filled pack over time and define acceptance criteria for handling, leakage and dissolution before confirming a production specification.
For a useful first review, send your application, current material or sample, dimensions, equipment, performance target, estimated quantity and destination. Our team can discuss a starting specification and sample arrangement.

Frequently asked questions
Does this film resist all acids and alkalis?
No. This product is offered for formulation-specific evaluation, not universal chemical resistance.
Can thickness compensate for an incompatible formulation?
A thicker film does not establish chemical compatibility. Review the grade and actual formulation first.
What should I send for technical review?
Send composition and concentration information, safety data where available, target dose, storage conditions, contact duration and mixing process.
