Material comparison
PVC vs TPU Dry Bags: Which Material Should You Choose?
PVC and TPU can both be effective in dry bag construction. The best choice depends on how the bag will be used, stored, branded and positioned.
Key takeaways
- Compare the whole construction, not just material names.
- Match flexibility and environmental needs to the use case.
- Test proposed material with the chosen seam and closure design.
PVC considerations
PVC tarpaulin is commonly selected for robust coated-fabric constructions. Weight, hand feel and formulation can vary significantly.
TPU considerations
TPU is often considered where flexibility, low-temperature behavior or material-positioning requirements are important. Its processing and sourcing should be reviewed for the project.
Buyer decision framework
Compare sample hand feel, expected exposure, seam method, performance needs, compliance requirements and budget.
Buyer considerations
Use this guide as a structured conversation with your internal team and supplier. Make the application, construction, testing and commercial assumptions visible before approving samples or production.
Common mistakes
Comparing incomplete quotations, treating a material label as a full specification, and approving an unrecorded sample can all create avoidable risk. Keep a written brief and inspection plan alongside every project decision.
