01
Surface water and drip
Water and drip from fish and shellfish reach the tray flange and cause weak or leaking seals.
What we do · Every packaging test checks seal quality and water on the flange.
Fresh Seafood MAP Packaging
Build the tray packaging around the seafood, the tray, the film and the packaging mode. Our Hybrid Pro T680 tray sealer lists seafood and runs MAP, VSP and seal-only packs on one machine.
Typical route: tray supply → product loading → T680 tray sealing → inspection → case packing
Fresh Seafood MAP Packaging Challenges
Six points that decide whether a fresh seafood tray line runs well.
02
Shells, fins and sharp edges
Shells, fins and bone edges can pierce the film, most of all when skin film is drawn tight in VSP.
What we do · Film and packaging mode are checked against the edges of your product.
03
Shape and height in the tray
Whole fish, fillets and portions sit differently in the tray. Pieces above the rim get caught in the seal.
What we do · Product height and position are checked against your tray.
04
Gas mix and residual oxygen
Seafood products need different gas mixes, and MAP results depend on how much oxygen stays in the pack.
What we do · The T680 mixes O₂, CO₂ and N₂ with ±2% accuracy. The mix for your seafood is set in testing.

05
VSP fit
VSP suits some seafood better than others. Shape, height, edges and shells decide how the skin film forms.
What we do · VSP is checked with your product, tray and film before it is chosen.
06
Keeping it chilled
Fresh seafood warms up while filled trays wait for the sealer.
What we do · Tray supply, loading and sealing rates are matched so filled trays do not wait.
Recommended Packaging Route
Tray supply, loading and sealing are planned together, then matched to the seafood.
- 01
Tray Supply
Empty trays to the line
- 02
Product Loading
By hand or automatic, as the project needs
- 03
T680 Tray Sealing
MAP, VSP or seal-only
- 04
Inspection and Labeling
Checks and labels on the sealed tray
- 05
Case Packing and Palletizing
Trays into cases, cases onto pallets
Tray denesting, automatic loading and labeling are planned for each project.
Modules Matched to the Product
Each module is chosen for the seafood and the tray, then integrated into the line.
Hybrid Pro T680 Tray Sealer
Lists seafood. MAP, VSP and seal-only on one machine, on plastic or paper-based trays. Up to 20 (MAP), 12 (VSP) or 25 (seal-only) cycles/min.*
Tray Tooling
Made for your tray and cavity layout. Standard tooling seals 4 trays per cycle, and a quick-change cart swaps tooling in about 15–30 min.
Inspection
Checkweighing, metal detection, combined units, or X-ray where the application calls for it. The method is chosen once the product, tray and film are known.
Case Packing and Palletizing
Robotic case packing and palletizing, integrated around the sealed tray, the case pattern, the case rate and the pallet pattern.
*Machine maximum. Actual output depends on product, tray, film, gas mixture and tooling.
Define Sustainable Good Output
A fresh seafood tray line runs at the pace of its slowest stage, so we check every stage instead of quoting the sealer's top speed.
Good trays per minute= Good cycles per minute × Trays per cycle
Trays per cycle come from your tooling, so we do not multiply the 20 cycles/min maximum by four. We set the line target from tests and agreed FAT conditions.

Enough accepted trays per minute

Case packing
Enough cases per minute at the trays per case you need
- 06
Palletizing

Packaging Mode and Machine Fit
Choose the mode first. MAP, VSP and seal-only all run on the T680.
MAP
Vacuum, then gas filling with an O₂ / CO₂ / N₂ mix. Residual O₂ below 0.5%.
Up to 20 cycles/min*VSP
Vacuum skin packaging: the top film is formed closely around the product. Checked for each seafood product.
Up to 12 cycles/min*Seal-Only
Lidding film sealed onto the tray without changing the atmosphere.
Up to 25 cycles/min*
*Machine maximum. Actual output depends on product, tray, film, gas mixture and tooling.
Why the T680
Seafood is one of the T680's listed applications, and one machine covers all three modes on plastic or paper-based trays. Detailed specifications are on the machine page.

The machine, industry, tray format and services behind this application.
Is the T680 suitable for fresh seafood?
Yes. Seafood is one of the T680's listed applications. The setup for your product is defined from the seafood, tray, film and packaging mode.
Which packaging modes can I use?
MAP, VSP and seal-only, all on the T680. The tooling and settings change with the mode and the tray.
How fast does the T680 run?
Up to 20 cycles/min in MAP, 12 in VSP and 25 in seal-only. These are machine maximums. Actual output depends on the product, tray, film and gas mix.
Does 4 trays per cycle mean a fixed number of trays per minute?
No. Four trays per cycle is the standard tooling. Your tray and product decide the cavity layout, and the sustainable output is confirmed in testing.
What residual oxygen can MAP reach?
The T680 reference for MAP is residual O₂ below 0.5%. We measure it on your pack in the test.
Which gas mix should I use for seafood?
The T680 mixes O₂, CO₂ and N₂ with ±2% accuracy. The right mix depends on your product and pack, and is set during testing.
Can one VSP setup work for all seafood?
No. Product shape, height, edges and shells, the tray and the film are checked for each product.
Will MAP give my seafood a fixed shelf life?
No. Shelf life depends on the product, gas mix, tray, film and storage, so it has to be tested for your pack.
