Pack quality

Filled pack quality checks for carbonated drinks.

A carbonated filling project should define how finished bottles or cans will be judged after filling, closing and handling.

Finished-pack checks should be matched to the drink and container. A beer can may require different checks from a PET sparkling water bottle or a crown-capped cider bottle. The goal is not to create unnecessary paperwork; it is to make acceptance practical and repeatable.

Fill level or net contentAgree whether visual fill, weight, volume or another site method is used.
Foam and appearanceCheck foam carryover, splash, product loss and settled appearance.
Closure or seamInspect cap seating, torque, crown application, ROPP finish or seam quality as applicable.
Leaks and pressure retentionUse the buyer’s agreed leak and hold checks for the package.
Carbonation and oxygenUse validated measurement methods where carbonation or oxygen is a contractual acceptance point.
  • Record product temperature and start/stop conditions.
  • Log container and closure batch details where possible.
  • Separate foam, low fill, cap/seam and handling rejects.
  • Keep sample photographs where visual appearance is important.

A good commissioning process does not simply run containers through a machine; it proves that the filled package is acceptable for the buyer’s production and quality expectations.

Buyer questions

Questions to resolve before specification.

Are fill-level checks enough?

No. Carbonated drinks may also need closure, seam, leak, carbonation, oxygen and visual checks.

Should quality checks be the same for cans and bottles?

Some principles overlap, but cans and bottles need different closure or seam checks.

Who sets the acceptance standard?

The buyer should define the product quality standard, with Lancing advising on practical machine-related checks.

Can checks be added after installation?

They can, but it is better to define them before FAT/SAT so the line is tested against the right expectations.

Ready to specify the route?

Send the product, package and output details.

Lancing can review the drink type, carbonation target, container, closure or seam route, target output, utilities and site requirements before recommending the machinery path.
