Dry Pet Food VFFS: Record the Format Before Choosing a Machine

Choose a dry pet-food packaging route by identifying how the product must enter the package. Loose kibble can be released as a measured portion through a vertical filling path. A discrete treat may need support and orientation on a conveyor. A premade pouch arrives as a converted bag that must be opened and held during filling. Keep the product, portion and package construction together when comparing those routes.

Record the actual kibble or treat sample, labeled fill quantity and bag drawing before discussing a machine configuration. Note whether the product is sold as loose pieces, a counted group or an individual item that must remain whole. Include coating, dust and visible fragility. These details define the handling question that a representative sample review needs to answer.

A shelf bag shows its shape and closure but often hides how it was made. A pillow pack may come from a horizontal wrapper or a vertical bagger. Trace the product movement and identify whether the material starts as roll film or a finished pouch. Then connect that route to portioning, closing and discharge requirements.

For loose dry kibble sold by weight, review the feeder, weighing or dosing unit, transfer chute and forming tube as a complete product path. Observe whether the incoming sample is whole, dusty, oily on the surface or prone to collecting in a contact area. Keep its grade and lot with the trial conditions so later observations can be compared with the material that entered the line.

A brittle treat or freeze-dried piece needs a defined damage check. Agree what counts as a defect, retain an incoming baseline and compare it with safely collected samples after the relevant transfers. Record broken pieces and fines separately from incomplete portions or product retained in the equipment. Identify the collection point and use the same classification method across samples.

If an item must keep a particular position or remain in an arranged group, review supported transport and wrapping. For a falling portion, inspect contact points and the discharge into the bag. Bag size alone cannot establish gentle handling; the trial must connect damage observations to the actual transfer path and settings.

Wet food, gravy, paste and retorted products require a separate process and packaging review. Route those projects to the responsible product and process team before applying a dry-food handling or acceptance plan.

On a horizontal flow wrapper, an item or arranged group travels on a conveyor and film wraps around it. On a vertical form-fill-seal line, a measured portion falls through a forming tube into a bag made from roll film. On a premade-pouch line, the filling station receives a bag already made by a converter. State this entry route in the project brief so the quotations address the same production task.

Both horizontal and vertical film routes can produce a pillow pack with a longitudinal seam and two end seals. Inspect the product path as well as the finished seams. Where position or support is essential, discuss those needs with a flow-wrap supplier. For a portioned dry product, review whether the feeder, doser and drop path can deliver the intended pack while meeting the agreed handling criteria.

For premade pouches, supply production samples and the converter's drawing. Review pouch pickup, opening, filling support and top sealing. Include zipper handling when the sample has a reclosable feature. A flat drawing should identify the bottom and gusset construction because outside dimensions alone do not establish usable fill volume.

Keep separate records for products that need different entries. Loose kibble in a plain pillow bag and treats in a resealable pouch may need different tooling, material handling and inspection. Compare each configuration against its own product and pack requirements.

Identify the closure on the actual pack sample: a pillow construction, side gussets, a flat bottom with edge seals or a zipper pouch. Mark the seam completed after filling and the space needed to make it. For a zipper, establish whether the converter supplies it already attached or whether the proposed equipment scope includes an application operation. Keep the package drawing and component revisions with that decision.

Review the pouch mouth and the product entry together. The filling outlet must deliver the intended portion while the handling arrangement supports the bag. Inspect product caught near the closure separately from wrinkles or a pouch-opening failure. For a dry product with oil on its surface, record contact and residue at the filling and closing areas during the representative run.

For an open-mouth bag, list bag presentation, support, filling and closing as separate operations. A premade zipper bag and a roll-film bag can have a similar retail appearance while requiring different equipment interfaces. Ask the supplier to identify how the quoted arrangement performs each operation on the supplied sample.

If the specification includes gas flushing, record the gas-supply and package-measurement requirements separately. Define the package objective and inspection conditions with the responsible product team, alongside the closure review.

Complete one route record for each product and pack. Identify loose kibble or a discrete treat, its lot and visible condition, the labeled fill quantity and the specification revision. Add the package construction and the required entry: a dropped portion, a supported item or filling into an existing pouch. Keep the sample photograph and package drawing linked to the same entry.

Record the closure made after filling, any zipper operation and the destination of the finished pack. Include downstream inspection or case handling where it belongs in the project scope. For fragile pieces, link the incoming baseline and damage observations to the transfer points being reviewed. Complete measurement fields during the corresponding checks and retain their method references.

Carry finished dimensions and material details from the approved drawing into the tooling review. For roll-film VFFS, verify the unfolded web, seam allowance and forming arrangement. For a premade pouch, verify opening, gripping and usable filling space with the actual pouch. Dimensions support these route-specific checks once the team knows which operations the machine must perform.

Assign each open question to a person and a specific next item, such as a revised drawing, product sample or handling observation. Separate product records make it easier to see whether two proposed SKUs can share a configuration and what must change between them.

Define the handling and finished-pack criteria before arranging a sample run. Include portion measurement, product condition after transfer, the space available for closure and the discharge handoff. For a discrete piece, state the damage classification and sampling locations. For loose kibble, retain individual fill results and the events around replenishment, pauses and restart.

List the quoted feeder, doser, forming or pouch-handling arrangement and included format parts. Keep sample lot, packaging material and settings with the observation record. If the trial uses a substitute product, pouch or film, identify the difference and decide which acceptance questions still require the intended production material.

The configuration review should end with a proposed route and a clear set of checks for the selected product and pack. Treat later changes in coating, piece geometry or package construction as new review inputs. Product treatment, storage conditions and shelf-life validation remain with the responsible food and packaging teams, alongside the equipment project.

Send our engineering team the product and lot identification, target fill quantity, bag style, package drawing and the handling issue you need to resolve. Include a photograph of the actual kibble or discrete pieces and describe their coating, size variation and observed fragility. These inputs connect the feeding and weighing arrangement to the intended pack.

Use the WhatsApp link below to share the brief and its drawing or specification references. Our configuration review covers the product path, portioning, film or pouch handling and the line interfaces. Where a handling question needs representative material, define the observation and acceptance method for the sample run.

Keep the sample identity, portion, packaging material and proposed equipment arrangement together in the project record. A trial evaluates that combination, so a later product or format change needs its own review. Confirm the sample quantity, packaging material and receiving arrangements with our team before shipping. The resulting configuration scope should identify the included feed and dosing equipment, format parts, utilities and handover documents.

Start the route record with the actual kibble or pet-food piece, its surface condition, the labeled fill mass and a pack drawing. For roll-film VFFS, follow the material through the feeder, weigher, transfer chute and forming tube. Inspect the product before and after transfer, and keep fines, broken pieces, bridging and product carryover as separate observations. Compare the fill's settled volume with the space available below the seal. A larger-looking bag can still leave too little clear sealing area when the product settles unevenly.

Treat premade pouches and open-mouth bags as separate handling routes. Record how each bag is supplied, opened and supported during filling; a flat-bottom appearance alone does not identify the machine that makes or fills it. For a zipper pouch, include the opening and closing operations in the review. For an open-mouth sack, document the closing equipment and handoff separately from retail roll-film bagging.

Our engineering team uses the completed route record to identify the forming, dosing, feeding and closure checks for the selected pack. Retain the product lot, film or pouch sample and settings with each observation. Enter trial measurements against that run, keeping unmeasured cells blank until the corresponding check is completed.
