UAHFW5 Vacuum Sealer: What 28 cm Roll Storage Changes

UAHFW5 Vacuum Sealer: What 28 cm Roll Storage Changes
A 28 cm bag mouth is the purchase boundary: choose a wider roll and the machine cannot close it in one pass. The UAHFW5 vacuum sealer is a 110W external vacuum sealer that pairs 75 kPa suction with 12 L/min ±15% flow, built-in roll storage, a cutter, and a 3 mm heating strip.
// 01 — Key takeaways
Founded in 2005, Guilin Prime Household Products Co., Ltd. documents its company history and export reach in the Trust Center.
The sealing width sets the maximum bag-mouth span for one pass.
Suction is one part of package performance; the bag path and finished seam still decide the result.
The flow figure describes air movement, while 75 kPa describes the pressure target.
Four units share one export carton, supporting warehouse and freight planning.
// 02 — Decision frame
What does 28 cm roll storage change in a vacuum sealer?
Built-in roll storage changes the buying decision from machine-only performance to workstation flow. UAHFW5 stores bag material inside the housing, uses an auto-lock cutter to set bag length, and seals openings up to 28 cm. Buyers should map the intended rolls, portions, labels, and operator sequence before comparing headline pressure.
Measure the bag mouth, not the roll length
The 28 cm figure limits the open edge placed across the heating strip. It does not limit how long an operator can cut a bag from a roll. A buyer can vary bag length for different portions, but every open mouth still needs to lie flat inside the stated seal width.
The available product data does not give the roll compartment’s maximum diameter. Include the intended roll in pre-production acceptance; width alone does not prove that it sits and feeds correctly.
Treat the cutter as part of the packing station
The auto-lock bag cutter removes one loose tool from the normal make-bag sequence. The operator cuts one end, seals it, fills the pouch, evacuates air, and closes the second end. That sequence matters when a distributor sells custom-length bags as the product’s main convenience.
Dry/Moist, Vacuum+Seal, Seal Only, and Pulse Vacuum divide the workflow into distinct controls. Pulse mode gives the operator manual influence over delicate or mobile contents; Seal Only supports the first end of a roll-made bag.
// 03 — Specifications
What does the UAHFW5 vacuum sealer specification show?
UAHFW5 is a 110W ABS external sealer for 100–220V, 50–60Hz supply. Its working figures are 75 kPa suction, 12 L/min ±15% flow, a 28 cm seal width, and a 3 mm heating strip. The included kit adds a bag roll, flat vacuum bags, an external suction tube, and a cord.
UAHFW5 spec sheet
Rev. 2026.08
This table defines the selected product configuration. Put the chosen bag structure, plug, labels, and destination-market requirements in the order file.
| Spec | UAHFW5 | Why it matters |
| Housing material | ABS | Sets the body material for color and surface review. |
| Rated power | 110W | Feeds the electrical label and market file. |
| Input | 100–220V, 50–60Hz | Sets the electrical range; the destination plug remains an order choice. |
| Motor rated voltage | DC 15V | Identifies the motor platform inside the appliance. |
| Sealing width | 28 cm | Sets the largest stated bag-mouth span for one pass. |
| Heating strip width | 3 mm | Defines the nominal heated band used to form the seam. |
| Suction | 75 kPa | Sets the vacuum target for procurement and acceptance. |
| Flow rate | 12 L/min ±15% | Describes rated air movement during evacuation. |
| Accessories | Bag roll, flat vacuum bags, external suction tube, cord | Defines the kit for packing and accessory trials. |
How do 75 kPa and 12 L/min differ?
Pressure and flow answer different questions. Pressure expresses the vacuum target; flow describes air volume moved over time under the supplier’s rating method. For a useful comparison, run the same bag structure, package volume, and load, then assess evacuation behavior and the cooled seam.
What does a 3 mm heating strip tell buyers?
Heating-strip width describes the nominal heated band, not a universal seal-strength result. Film construction, surface condition, temperature control, and dwell behavior also shape the seam. Set the acceptance method with the intended bag lot and representative dry and moist loads.
// 04 — Model choice
How does UAHFW5 compare with three factory models?
UAHFW5 centers the integrated roll-and-cutter workflow, while three factory alternatives change bag width, controls, pump arrangement, and opening quantity. UAH01T is the wider touchscreen platform, UAH34A is the dual-pump roll-storage alternative, and UAH56G is the compact touchscreen option. Compare the full configuration before comparing unit prices.

Four product configurations in one decision table
Match workflow and hard specifications to the retail brief, then read every unit price with its tier quantity. A lower unit figure at a smaller opening tier does not establish equivalent features or the same quote scope.
| Model | Workflow | Power, suction, seal width | Opening price tier |
|---|---|---|---|
| UAHFW5 | Built-in roll storage, auto-lock cutter, buttons | 110W; 75 kPa; 28 cm | $25.44 at 1,000 units |
| UAH01T | Watch-style touchscreen, 7 modes, detachable base | 135W; 70 kPa; 31 cm | $12.50 at 10 units |
| UAH34A | 30 cm × 5 m roll bay, sliding cutter, dual pump | 135W; 60–95 kPa dry; 30 cm | $23.00 at 10 units |
| UAH56G | Waterproof touchscreen, external hose, detachable base | 120W; 65 kPa; 30 cm | $10.50 at 1 unit |
When does UAHFW5 earn a shortlist place?
Choose UAHFW5 when an enclosed roll-and-cutter sequence, detachable drip tray, and one-hand lock hook belong in the retail brief. It also suits an accessory plan that includes both bags and an external suction tube.
When should width or controls win instead?
UAH01T is the wider touchscreen option in this set. UAH34A is the closer roll-storage alternative when a 30 cm by 5 m compartment and dual pumps drive the brief. UAH56G suits a compact touchscreen proposition. Compare configuration first because the first price tiers use different quantities.
// 05 — Bag system
Which bags fit a 28 cm external vacuum sealer?
Use a bag system designed to preserve an air path while an external machine clamps the mouth. Keep the open edge within 28 cm, lay it flat over the 3 mm heating zone, and keep food or liquid away from that zone. Roll material also needs to fit the built-in storage compartment and cutter path.
Why does an external sealer need an air channel?
An external vacuum sealer draws air through the same opening it later closes. If the two film faces collapse into a smooth blockage before evacuation finishes, air can remain inside. Textured or channeled material made for external extraction maintains a route toward the pump while the lid is closed.
The included flat bags do not define a universal film specification. In the purchase file, name the structure, width, thickness, texture, roll diameter, and intended pack types so the machine and consumable arrive as one matched system.
How should operators protect the seal zone?
Leave enough unfilled film to place the mouth flat, without folds or residue across the 3 mm band. Use Moist mode where the product behavior calls for it, and use Pulse Vacuum when unrestricted evacuation could move liquid or compress a fragile item.
The detachable drip tray supports cleanup after moisture enters the collection area. It does not turn the machine into a liquid packer, so the operating brief should define which products and fill states are in scope.
// 06 — Acceptance
How should buyers test a pre-production UAHFW5?
A pre-production plan should follow one complete roll-to-package sequence with the production-intent film, representative contents, final artwork, and accessory set. Record the cut, first-end seal, fill, evacuation, final seam, cleanup, and carton handover as separate outputs. This reveals workflow faults that a suction figure alone cannot show.
Run the complete roll-to-bag sequence
Load the intended roll, pull material through its designed path, cut several required lengths, and close the first end with Seal Only. Record skewed cuts, drag, loose roll movement, and usable bag geometry. Repeat with the shortest and longest planned packs rather than one convenient demonstration pouch.
Test vacuum and seal as separate outputs
Use named dry, moist, dense, and fragile loads from the target assortment. Record mode, fill amount, headspace, evacuation behavior, liquid movement, and final package shape. Then inspect the full seam after cooling for folds, gaps, scorching, contamination, or uneven bands.
Set one written leak or peel method with a numerical acceptance limit before production. That single protocol makes results comparable across the pre-production unit, line inspection, and any warranty claim.
Record cleanup, accessories, and packing
Remove and refit the drip tray, operate the one-hand lock, and exercise the external suction tube with the intended compatible container. Count the bag roll, flat bags, tube, and cord. Match the unit box and export carton to the product record.
// 07 — Commercials
What do price, MOQ, and lead time mean for UAHFW5?
UAHFW5 is priced at $25.44 per unit for 1,000 units, which is also the standard MOQ. Typical production lead time is 15–30 days, depending on volume and customization. Request a quotation that separates product configuration, packaging, delivery basis, and destination documents so the commercial scope is clear.
How should buyers use the opening quantity tier?
Budget $25.44 per unit at 1,000 units for the stated configuration. Ask for a new quotation if quantity or configuration changes; no additional UAHFW5 tier is published, so compare actual quote scopes instead of extrapolating a trial price or volume discount.
Which payment and shipping terms are recorded?
Use 30/70 T/T for the payment plan and select FOB China, EXW, or CIF for the delivery basis. Name the Incoterm, destination, freight responsibility, carton basis, and required documents on the quotation so the unit price and delivery boundary remain distinct.
What can a private-label buyer customize?
OEM, ODM, and private-label options include logos, colors, packaging, accessory bundles, buyer-supplied branding, and retail-ready box design. The electrical range does not choose a market plug by itself; put the plug, rating label, language, and warnings in the order file.
// 08 — Food safety
What food-safety claims should vacuum sealer copy avoid?
A vacuum sealer removes air and closes a compatible package; it does not sterilize food or replace refrigeration, freezing, cooking, or a regulated reduced-oxygen process. Retail content should separate machine specifications from food-handling instructions. Shelf-life statements need a named food, package, temperature, method, and supporting evidence rather than a universal multiplier.
What is vacuum packaging?
The USDA Food Safety and Inspection Service explanation defines vacuum packaging as removing substantially all air before sealing so a vacuum remains inside. That definition supports a clear function claim for UAHFW5 without implying that oxygen removal makes every food shelf stable.
Can vacuum-sealed food stay at room temperature?
Not merely because it is vacuum packed. The USDA FSIS safety answer says perishable vacuum-packaged foods belong at or below 40°F in a refrigerator or at 0°F in a freezer. It also states that vacuum packaging does not replace safe processing for room-temperature storage.
When does reduced-oxygen packaging need formal controls?
The FDA Food Code is a model for retail and food-service safety rules and addresses reduced-oxygen packaging. USDA’s vacuum-sealing technical assistance likewise tells institutional operators to consider safe practices, package type, product characteristics, and local requirements.
// 09 — Manufacturing
How we manufacture UAHFW5 for private-label orders
Guilin Prime Household Products Co., Ltd. operates from a 15,000 m² factory with 205 workers and stated capacity of 100,000 units/month. For UAHFW5 private-label orders, the production file moves from released housing and artwork requirements to component assembly, defined functional inspections, packing, destination compliance, and warranty documentation.
In-house tooling and private moulding
The ABS housing, roll bay, cutter path, one-hand lock, control labels, color, logo, and retail pack are tied to the released configuration. Private-label artwork is settled before the visual parts and printed materials enter the production sequence.
Pump and PCBA burn-in controls
The released production route places the pump, motor platform, and PCBA through assembly and functional burn-in before final assembly. The order-specific QC plan defines the duration and acceptance limits; no UAHFW5 burn-in result was supplied for this article.
Quality control inspection points
The UAHFW5 QC route identifies air removal, heating-strip operation, cutter travel, lock engagement, drip-tray fit, and external-suction-tube function as inspection points. Packing inspection uses this model’s unit and export-carton dimensions. No operation-specific roll-fit, cutter-alignment, seal-strength, or leak-test result was supplied with the product data.
CE, RoHS, and 12-month warranty
The compliance stage maps the selected configuration to CE and RoHS requirements for the destination and records the 12-month manufacturing-defect warranty. Put the market, plug, rating label, instructions, and required declarations in the order file; this article attaches no certificates.
Mi Lan’s documented review observation: The 28 cm roll workflow should be judged as one chain: intended-roll fit, square cutter alignment, and a clean first-end seal before filling.

// 10 — Buyer fit
Who should shortlist the UAHFW5 vacuum sealer?
Shortlist UAHFW5 when a distributor wants roll storage, an integrated cutter, button controls, four operating modes, a detachable drip tray, and external-container support in one retail offer. Move to another factory model when the brief prioritizes a wider bag path, touchscreen controls, dual pumps, a different roll compartment, or a lower opening quantity.
Distributors selling roll-based bag systems
The product story is easy to demonstrate: store the roll, cut the needed length, close one end, fill, evacuate, and seal. That sequence can support starter kits and replenishment rolls when the chosen film fits the compartment and external-extraction path.
Private-label programs needing a defined feature set
Use the button interface, four working modes, external suction, detachable drip tray, and one-hand lock as the fixed feature brief. Build the private-label offer with logo, color, packaging, and accessory choices, while keeping pressure and food-preservation claims within the supplied product and food-safety evidence.
Buyers whose priority is width or interface
Use the model matrix when the brief changes. Choose by bag width, control interface, pump arrangement, roll-storage design, and opening quantity, then request the matching configuration. These are different product positions, not a ranking of universal quality.
// 11 — Buyer questions
Questions buyers ask before ordering a vacuum sealer
Buyers commonly ask how much suction is enough, whether roll storage justifies its footprint, which bags work, how to scope a quotation, and whether vacuum-packed food can sit at room temperature. The answers below turn those People-Also-Ask-style questions into purchase actions and connect the food-handling point to official guidance.
What is a good suction power for a food vacuum sealer?
Is a built-in bag cutter worth it?
Can any bag work with an external vacuum sealer?
What is the MOQ for UAHFW5?
Can vacuum-sealed food be kept at room temperature?
// 12 — Conclusion
Conclusion: where UAHFW5 fits a roll-storage range
UAHFW5 belongs in a wholesale range when custom-length roll bags and an integrated make-bag station match the operator’s work. Base the final buying decision on a documented pre-production protocol covering intended-roll fit, cutter tracking, first-end seal formation, representative loads, cleanup, accessories, artwork, and the specified pack-out.
The model is not the automatic choice for every external-sealer line. Use the comparison matrix to switch when the brief favors more width, a touchscreen, dual pumps, a different roll bay, or a smaller opening tier. Keep UAHFW5 when its enclosed roll-and-cutter sequence is the stronger retail and operator fit.
