There is no such thing as a "good" bag or "bad" bag. In cheese packaging, what matters is whether the bag works for your particular application.
- Prior to using a particular cheese bag on a regular basis, you should "qualify" the bag for your process. That means running a small number of bags on machinery under standard conditions. Ideally, technical experts from your bag vendor should be present during the trial run.
- Examine the package for an adequate, leak-proof seal. Put it through your standard storage and distribution process. Only then can you be confident that this particular bag works with your manufacturing process.
- If anything in your process changes, you should re-qualify your packaging material. In order to keep your cost as low as possible, packaging materials are usually designed with a very small margin of error. Even something as simple as a new sealing bar can be reason for re-qualifying your packaging material. This gives you the best guarantee that the manufacturer will stand behind the bag in the event of a failure. Getting the manufacturer's agreement in advance that their bags are qualified for use in your process will protect you and reduce the possibility of disputes later on.
