You have finished product, safe, shelf-stable jerky or meat sticks. Now it has to become thousands of sealed, dated, retail-ready packs, and then cases and pallets, without losing shelf life or blowing the budget. That step, filling and packing at scale, is a real operation with real equipment, and it is where a lot of growing brands hit a wall: build and staff the line yourself, or hand it to a co-packer who already has it. This guide walks through what that step actually involves and how to think about the build-versus-outsource decision.
The path from bulk product to shelf runs through three stages: primary fill-seal, atmosphere and quality control, and secondary packaging for retail. Each has its own equipment and its own failure points. It is the deep dive behind the filling-at-scale decision in our packaging playbook for the protein-snack boom.
Stage 1: Primary Fill-Seal
The core of the operation is form-fill-seal (FFS) equipment, which forms the pack from a roll of film, fills it with product, and seals it in one continuous automated motion. There are two types, and the choice depends on the product and format:
- Vertical form-fill-seal (VFFS). Film is pulled over a forming tube, product drops in by gravity, and the pack is sealed. Efficient and space-saving, well suited to jerky pieces, sticks, and pillow or gusseted bags, and to nitrogen flushing. The most common choice in snack food.
- Horizontal form-fill-seal (HFFS). The pack is formed and filled horizontally, better for products that cannot survive a vertical drop and for premium formats like stand-up pouches, zippered packs, and four-side-seal packs, with strong control for modified-atmosphere packaging.
These lines run fast, commonly from roughly 60 to well over 200 packs per minute depending on product and machine, which is exactly why consistency and uptime matter so much. A single jaw misalignment or film-tension fault can produce thousands of failed seals before anyone catches it, and a failed seal on a meat product is a food-safety and shelf-life problem, not a cosmetic one.
Stage 2: Atmosphere and Quality Control
For an oxygen-sensitive meat snack, sealing is only half the job; controlling what is inside the pack is the other half:
- Modified atmosphere / nitrogen flushing. Integrated into the fill-seal step, the pack’s headspace is flushed with nitrogen to displace oxygen (commonly to around 2% or below), slowing fat oxidation and extending shelf life. HFFS lines in particular offer fine gas control.
- Seal integrity and fill-weight verification. Checkweighers confirm each pack is within weight tolerance, and seal checks catch leaks before product ships. On a line running tens of thousands of packs per shift, these checks are what keep a small fault from becoming a large recall.
- Coding and labeling. Date and lot coding and label application, done in-line, keep every pack traceable, which matters for both retail and the USDA-regulated environment meat snacks live in.
Stage 3: Secondary Packaging for Retail
Sealed single packs are not shelf-ready yet. Retail wants cartons, multipacks, club packs, and displays, and that is a second packing operation:
- Cartoning. Sealed pouches or sticks loaded into folding cartons or display boxes.
- Club, variety, and combo pack-outs. The multipacks and assortments that club and grocery channels want, and that a brand chasing a broadening audience needs to offer.
- Tray and case packing, then palletizing. Grouping packs into cases and onto pallets, engineered so the load ships without crushing and stacks to retailer requirements.
- Point-of-purchase displays. Retail-ready display units that put the product in front of the shopper, increasingly important as the category competes for attention on a crowded shelf.
Build It or Outsource It?
A brand can build this in-house, but the honest math usually favors outsourcing, especially early. Building means buying VFFS or HFFS equipment (often six-figure, with lead times measured in months), adding MAP and checkweighing, hiring and training operators, maintaining the line, and carrying all of it as fixed cost whether demand is up or down. For a category as seasonal and promotion-driven as meat snacks, that fixed cost is a real risk.
Outsourcing to a co-packer who already has the certified line, the equipment, and the trained operators converts that capital expense into a variable one, and lets a brand scale up for a promotion or down for a slow quarter without owning the overhead. The trade-off is choosing the right partner, one with the equipment, the certification, and the capacity for your product and formats.
Whether you build or outsource, fill-seal lines only pay off when they run. Downtime on a packaging line backs up everything behind it. If you outsource, ask a prospective co-packer how they maintain uptime, how they handle equipment service, spare parts, and preventive maintenance. A partner who sells and services packaging equipment, not just operates it, tends to keep lines running better, because keeping equipment up is part of their core business, not an afterthought.
How Korpack Solves This
Korpack covers all three stages as one operation, and it is unusual in also selling and servicing the equipment that runs them.
Korpack runs vertical and horizontal form-fill-seal and pouch filling and sealing equipment, with the checkweighing, coding, and labeling that keep every pack accurate and traceable. It handles the primary pack that protects a meat snack’s shelf life.
Cartoning, tray and case packing, club, variety, and combo pack-outs, subscription kitting, and Point-of-Purchase display builds, the secondary packaging that turns sealed product into a shelf-ready SKU for grocery, club, and convenience channels.
Because Korpack also sells and services packaging automation, keeping lines running is core to the business. That includes trained service technicians, parts support, an equipment database, and, for brands weighing their own line, a Loaner Program and financing that lower the barrier to automating.
The single-source advantage ties it together: the same partner supplying the barrier film runs the fill-seal that uses it and the secondary packaging that follows, so the material, the fill, and the pack-out are designed to work together rather than sourced from three vendors and forced to fit. For brands that want to hold buffer stock without carrying it themselves, vendor-managed inventory keeps materials ready for the next run.
Getting a protein snack from bulk to shelf is an engineering and operations problem. Owning the whole line is optional; getting it right is not.
Korpack runs the fill-seal, atmosphere control, and retail-ready secondary packaging that turn finished jerky and sticks into shelf-ready product, with the equipment expertise to keep the line running. Let’s talk about your volumes and formats.

Frequently Asked Questions
What equipment is used to package meat sticks and jerky?
Form-fill-seal equipment is the core: vertical form-fill-seal (VFFS) for jerky pieces, sticks, and pillow bags, and horizontal form-fill-seal (HFFS) for stand-up pouches and premium formats. Lines commonly also integrate nitrogen flushing or modified atmosphere packaging, checkweighing, and date/lot coding, followed by cartoning and case packing for retail.
Should I buy my own packaging line or use a co-packer?
For most growing brands, outsourcing to a co-packer is faster and less capital-intensive than buying fill-seal equipment (often six-figure, with months-long lead times), adding atmosphere control and checkweighing, and hiring operators. Outsourcing converts fixed cost into variable cost and lets you scale with demand. Building can make sense at high, steady volume, but it carries fixed overhead through slow periods.
How fast do fill-seal lines run?
Depending on the product and machine, form-fill-seal lines commonly run from roughly 60 to well over 200 packs per minute. At those speeds a single seal or fill fault can affect thousands of packs quickly, which is why in-line checkweighing, seal verification, and line uptime are critical, especially for a meat product where a failed seal is a safety and shelf-life issue.
What is secondary packaging for a meat snack?
Everything after the sealed single pack: cartoning, club, variety, and combo multipacks, tray and case packing, palletizing, and point-of-purchase displays. It turns a sealed pouch or stick into a retail-ready SKU that ships intact and meets a retailer’s presentation and case requirements.
