What evidence should be agreed before acceptance testing for pet food packing machines?
Agree the products, pack formats, operating conditions and finished-pack checks before the trial. For each combination, record dose, count or weight results, closing checks and how failed packs will be identified and handled. Agree acceptable ranges and the evidence needed for acceptance.
Use representative dry kibble, treats or wet products from the intended range. Record the product condition, actual pack specification, intended fill and production pattern, and state which difficult cases the trial will cover. Keep untested products and formats explicit.
Plan pet food packing machines around your product, pack range, target output, cleaning needs and finished-pack checks. Discuss a practical line concept with Lancing using representative samples. Use this guide to resolve finished-pack checks and reject handling before it limits the final system.

Record the product batch and condition, pack material and format, intended fill, machine settings and agreed starting state. Note how quantity, product condition and the closing area will be inspected, including any limits of the checking method.
Include the normal product and pack range plus the difficult combinations that matter to the project, such as fragile pieces, wet products with solids or a small pack opening. Agree repetitions and trial duration with the team reviewing the result; do not substitute a smooth-liquid demonstration for a different product.
Record when fills, product condition or closures fall outside the agreed criteria, what intervention is needed and how affected packs are handled. Review recovery and repeat the relevant checks before resuming the trial. Keep product-process and shelf-life validation separate from the machine trial.
Identify the actual product and packing condition. For dry kibble or treats, inspect breakage and fines after transfer; for wet products, observe product passage, distribution of pieces and dosing cut-off where relevant. Keep these observations separate from the quantity result.
Use the intended bags, pouches, trays or containers, including their openings, closure features and required headspace. Record presentation, support, closing and discharge, and inspect product around the sealing or closure area. Keep untested pack variants outside the accepted scope.
Agree whether the required quantity is a dose, count or pack weight, then record the checking method, samples, acceptable range and individual results. A passing total weight does not by itself prove product condition or the distribution of a mixed product.
Count accepted finished packs over the agreed trial period, alongside refills, blocked feeds, interventions and rejected packs. For a short-run job mix, include emptying, cleaning, packaging changes and first-pack release rather than comparing only the fastest uninterrupted run.
Record the production sequence, contact-part cleaning and residue-removal steps defined by the site, together with line clearance and format restoration. Check the first packs after a change and retain the settings and observations used to release the next run.
Agree the finished-pack quantity, product-condition, seal or closure and coding checks that apply to the project. Record each failure, the affected-pack response, retest results and who reviews the evidence. List exceptions and untested combinations alongside the acceptance record.
