A vacuum sealer is a benchtop machine that pumps the air out of a bag and heat-seals it, so food keeps three to five times longer. The UAHFW4 is a 110W automatic vacuum sealer with built-in roll storage, a bag cutter and 75 kPa suction, built for wholesale and OEM supply.
// 01 — Key takeaways
Suction at the nozzle — pulls roughly 74% of the air out of the bag to slow spoilage and freezer burn.
Seal-bar width: wide enough for whole fish, bulk cuts and catering portions.
Sustains back-to-back sealing cycles on a busy prep line.
Dry, moist, vacuum-and-seal, seal-only and pulse vacuum from button controls.
MOQ in units, factory-direct from our Guilin, China plant.
Self-contained station: built-in roll storage, bag cutter, detachable drip tray and a one-hand lock hook in a single ABS and stainless-steel body.
// 02 — Definition
What is a vacuum sealer with roll storage?
A vacuum sealer with roll storage is an external sealer that keeps a bag roll inside the machine, so an operator can pull out any length, trim it with the built-in cutter and seal a custom bag in one place.
The UAHFW4 is exactly that kind of unit. Instead of feeding pre-cut bags, staff keep an embossed roll loaded in the body, draw the length each item needs, cut it square and weld the open end — no extra bag inventory to manage on the bench.
How does built-in roll storage work?
An internal compartment holds a standard embossed bag roll. The operator pulls the roll to length, seals one end to form a pouch, fills it, then vacuums and seals the other end. One roll replaces a whole shelf of fixed-size bags.
What does the bag cutter add?
The integrated slide cutter trims the roll square so the next seal sits flat and airtight. Clean, straight cuts mean fewer failed welds and less wasted film — a real saving when a kitchen seals dozens of bags a day.

UAHFW4 specifications and performance
The UAHFW4 runs at 110W on 100–220V with 75 kPa suction, a 12 L/min flow rate, a 28 cm seal bar and a 3 mm heating strip. Every figure below comes from the production unit, so you can match the model to your packaging volume.
UAHFW4 spec sheet
Rev. 2026.06
| Spec | This model (UAHFW4) | Why it matters |
| Rated power | 110 W | Sustains back-to-back sealing cycles |
| Voltage | 100–220 V (50–60 Hz) | One SKU ships to almost any market |
| Suction | 75 kPa | Removes about 74% of bag air to slow spoilage |
| Flow rate | 12 L/min (±15%) | How fast each bag is evacuated |
| Seal-bar width | 28 cm | Fits wide cuts, fish fillets and bulk portions |
| Heating strip | 3 mm | Wider weld means a stronger, more reliable seal |
| Build | ABS + stainless steel | Wipe-clean, food-safe housing |
| Modes | Dry, moist, vacuum+seal, seal-only, pulse | Handles dry goods and damp foods |
| Onboard | Roll storage, bag cutter, drip tray, lock hook | Make custom bags, catch liquids, lock the lid |
What does 75 kPa suction actually remove?
Standard atmospheric pressure is about 101.3 kPa, so a 75 kPa vacuum pulls roughly three-quarters of the air out of the bag. That is enough to tighten the film around dense, moist cuts and lock out the oxygen that drives oxidation.
Why the 28 cm seal bar and 3 mm strip matter
A 28 cm seal bar takes wider bags than typical 30 cm-class home units handle comfortably, and the 3 mm heating strip lays down a broad weld. A wider weld resists peeling in the freezer, where thin seals often fail first.
What do the five vacuum modes do?
Button controls switch between dry, moist, vacuum-and-seal, seal-only and pulse vacuum. The moist setting adjusts heat and timing for marinated or damp items, while pulse vacuum protects delicate contents from being crushed by full suction.
// 04 — Buying decision
External or chamber vacuum sealer: which do you need?
For most kitchens an external vacuum sealer like the UAHFW4 gives the best balance of speed, footprint and running cost. A chamber sealer wins for high-volume liquid packaging but costs far more and takes up much more bench space.
When is an external vacuum sealer the right choice?
Choose an external sealer for dry goods, portioned meat, sous-vide prep and mixed daily packaging. It is lighter, cheaper to buy, runs on inexpensive embossed rolls and stores easily — ideal for cafes, butchers, delis and home batch cooks.
When should you choose a chamber sealer?
Pick a chamber sealer if you seal large volumes of soups, brines or marinades every day. Chamber pouches cost less per unit, but the machines are heavier, pricier and slower to clean between liquid runs, so they suit dedicated production lines.
Air is the enemy of stored food. Pull it out, weld the bag tight, and you slow almost every process that spoils what is inside.

// 05 — Shelf life
How much does vacuum sealing extend shelf life?
Vacuum sealing removes the oxygen that drives oxidation, freezer burn and spoilage bacteria, so sealed food typically keeps three to five times longer. The exact gain depends on the food and on correct refrigeration or freezing after sealing.
How long does vacuum-sealed food keep?
Vacuum-sealed raw meat can hold one to three years frozen, versus six to twelve months wrapped loosely, and stays fresher in the fridge too. The USDA notes that food held constantly at 0 °F (−18 °C) stays safe indefinitely, because freezing pushes spoilage microbes into dormancy.
Does vacuum sealing prevent freezer burn?
Largely, yes. Freezer burn happens when air reaches the food surface and moisture sublimates into ice crystals. By pulling that air out and welding the bag shut, the UAHFW4 keeps dehydration and ice crystals off stored food far better than loose wrapping.
Is vacuum sealing a substitute for refrigeration?
No. Food-safety specialists at the University of Maine Cooperative Extension stress that vacuum sealing alone is not a method of food preservation and does not make food shelf stable. Keep sealed food refrigerated or frozen, and take extra care with fish to limit botulism risk.
// 06 — Manufacturing
How we manufacture the UAHFW4
Use At Home builds the UAHFW4 in-house at our Guilin, China factory. We control tooling, pump assembly, sealing tests and final inspection, which keeps quality consistent across large wholesale runs and makes private-label work straightforward.
In-house tooling & molding
Our own injection moulds shape the ABS and stainless housing, so we adjust labels, colour and branding without outsourcing tooling. That control shortens lead times and lets buyers commission private-mould variants for exclusive lines.
Pump & PCBA burn-in
Each vacuum pump and control board is powered up and burned in before assembly. Early electrical load testing catches weak components on the bench, not in your customer’s kitchen, protecting your brand from field returns.
Seal-integrity & vacuum test
Every batch is checked for suction level and seal strength. Inline tests on the 3 mm heating strip and pump confirm the unit reaches 75 kPa and welds a clean, airtight seam before it is packed.
Compliance & warranty
The UAHFW4 is built to export electrical norms, with CE and RoHS conformity available for EU-bound orders and a 12-month warranty. Confirm the exact certificate set for your destination market before you order.
// 07 — Wholesale & B2B
Wholesale, MOQ and OEM ordering
The UAHFW4 is made for distributors, hotel groups, catering suppliers and private-label brands. Factory-direct pricing, flexible customisation and container-ready packing make it a dependable line for repeat wholesale programmes.
What is the MOQ and lead time?
The minimum order is 1,000 units, with factory-direct pricing from $26.42 per unit. Standard production runs 15 to 30 days after sample approval and deposit, scaling with order volume and the level of customisation you need.
Shipping, Incoterms and payment terms
We ship FOB China with EXW and CIF options, and typically work on 30/70 T/T terms with Alibaba Trade Assurance. Export cartons hold four units at 10 kg, so container quantities are easy to plan for efficient freight.
Plug standards and voltage by market
The wide 100–220 V, 50–60 Hz input means one SKU covers most export markets — we simply fit the correct plug head for your destination, whether that is the EU, UK, US, Australia or the Middle East.
Can you do OEM and private-label?
Yes. As the manufacturer we offer OEM, ODM and private-label services across logo, colour, panel labelling, packaging and the accessory set of bag roll, flat bags, external suction tube and cord. Share your artwork and we will quote tooling and samples.
