Nylon (PA) Thermoforming Film — Food Package F2646 (50μm)
NL50 NY/PE thermoforming film used as a sealing film on continuous automatic vacuum thermoforming lines. Laminates with PET or OPP film to form a vacuum bag for chicken, ham, sausage, bacon, duck, meat, and seafood.
A Sealing Film Built for Continuous Vacuum Thermoforming
F2646 is the 50μm entry point of Intlpak's NL series, running as the sealing (top) film on continuous automatic vacuum thermoforming lines at high packing speeds. It is engineered for the best formability and twist resistance without pinholes, with the transparency and gloss that keep vacuum-packed proteins retail-ready through the distribution chain.
Where F2646 Is Used
- 1
Chilled and Frozen Vacuum Packs
Vacuum packaging film for refrigerated and frozen food. At 50μm F2646 is the sealing web rather than the forming web — it closes the pack over a cavity drawn from a heavier grade below it.
- 2
Fresh Meat and Seafood Packs
Fresh beef, chicken, pork, seafood, sausage, and fresh meat products. At 4% haze it is the clearest grade in the NL nylon (PA) family, which is what a retail-facing top web needs.
- 3
Ham, Bacon and Processed Meats
Ham, bacon, duck, and other ready-to-eat and processed meats. Sliced and portioned products are judged on appearance through the film, so the top web carries the clarity requirement.

Automatic Thermoforming Line Sealing
Sealing film on continuous automatic vacuum thermoforming lines, laminated with PET or OPP to complete the bag. The forming depth is set by the bottom web, chosen separately from 80μm up to 262μm.
Full Specifications — Thermoforming Nylon/PE Film Series
F2646 is the 50μm sealing-film grade in Intlpak's NL nylon/PE thermoforming film family — a 50 micron nylon sealing film with 4% haze, the lowest in the series, laminated with PET or OPP to form vacuum bags for chilled meat and deli products. The table below shows F2646 alongside the deeper-draw 80–262μm grades in the same series.

Questions About F2646
F2646 is only 50 μm — what is its role in the nylon family?
It seals; it doesn't form. Every other grade in the series carries a recommended forming depth and F2646 does not — it runs as the top web sealing against a formed bottom web, or in packs with negligible draw. For an actual formed cavity, start at F2624 (80 μm, 10–15 mm).
At 4% haze, is F2646 the clearest nylon grade?
It is. Haze climbs with gauge across the family: F2646 at 4%, F2624 5.7%, F2615 10%, F2606 12.5%, F2647 15% and 15309 20%. As a top web its clarity is what the shopper actually looks through, which is where the thin grades earn their place.
F2646's elongation is low — what should I watch on the line?
Tension and corners. At 370%/440% it is the least extensible in the family ( F2647 runs 620%/600%), meaning it tolerates stretch poorly. The upside is dimensional stability and accurate print registration; the downside is that it splits where the web is asked to draw. Pairing it over a deep-draw bottom web, confirm the top web sees no forming stress.
How does F2646's strength compare with grades twice its gauge?
Closer than expected. F2646 breaks at 450/380 kg/cm² and F2624 at 80 μm breaks at 460/470 — effectively level in MD, with the gap opening only in TD. Machine-direction strength is already substantial at 50 μm; cross-direction tear resistance is what added gauge actually buys.
What packs is F2646 used in?
Sealing film for continuous automatic vacuum thermoforming, across ambient, chilled and frozen food distribution. Run against a formed bottom web from the same family, its nylon layer supplies toughness and pinhole resistance — a standard top-web choice for meat and processed food vacuum packs.
Our sliced product looks dull through the pack — what makes a film look clear?
Haze, and it is published per grade. F2646 reads 4% haze, the clearest in Intlpak's NL nylon/PE range, because at 50 μm it carries the least material. Deep-draw grades in the same family climb to 12.5% at 150 μm and 20% at 262 μm. If shelf appearance matters more than draw depth, specify the lightest grade the pack format allows.
If we are only sealing and not forming, do we still need a nylon film?
Often yes, because the sealing web still has to carry barrier and puncture resistance even though it is never drawn. F2646 is the 50 μm sealing-film grade in the NL series, laminated with PET or OPP to close vacuum bags for chicken, ham, sausage and bacon. The forming web underneath is where draw depth is specified — the two are chosen separately.
