Buying a Large-Jar Blower for the Intended Jar Life Cycle
A large water jar may be used once or returned for washing and reuse. That distinction belongs in the package specification before selecting the preform and blower. Nominal gallon capacity does not establish durability or washing compatibility.
Define bottle acceptance
Specify drawing, neck finish, weight and the relevant load, leak and handling tests. Include the conditions the jar will encounter after filling. Use representative production preforms rather than an unusually heavy demonstration sample.
Check trial boundaries
Record accepted jars per hour and the utility conditions needed to achieve them. Inspect every mould cavity and identify required change parts. A brief successful blowing cycle does not establish the intended jar life cycle.
