Bag width and suction form one decision: UAH12A’s 70kPa pump matters only when the loaded mouth lies flat within its 32 cm sealing span, because a poor seal cannot retain the vacuum. A 70kPa vacuum sealer is a countertop external-suction machine. Its listed commercial opening tier is 100 units, separate from technical fit.
// 01 — Key takeaways
The documented Guilin operation spans 15,000 m², employs 205 workers and has capacity for 100,000 units per month. Founded in 2005, the company serves 56+ countries and backs UAH12A with a 12-month warranty. See the Vacuum Sealer China Trust Center for the documented factory facts.
The 70kPa vacuum sealer specification describes pressure; it does not replace a bag-and-load acceptance test.
The sealing bar accepts a wider laid-flat bag mouth than the 30 cm sibling models compared below.
The listed heating-strip width is a physical seal-format difference, not a marketing label.
One voltage range supports market-specific plug, manual and packaging programs.
The model record states both flow and tolerance, giving a usable reference for load trials.
// 02 — Decision
What are you buying in UAH12A?
UAH12A is an external-suction countertop model whose buying case combines a wider seal format with pulse and wet/dry control. Pressure, flow, electrical and accessory details matter as a system; the specification table keeps the complete numerical record, while the sections that follow explain which facts change pack fit, workflow and procurement.
Pressure and flow describe different jobs
Pressure describes the vacuum level the pump is intended to reach. Flow describes how quickly air can move under stated conditions. UAH12A lists 70kPa suction and 4 L/min ±15% flow, so a buyer can assess both endpoint and evacuation behavior.
A large, loosely filled bag and a compact, dense portion impose different air volumes. That is why a catalogue pressure value cannot predict the cycle time for every pack. The trial needs the intended film, portion and operator sequence.
Seal geometry controls the usable bag mouth
The 32 cm bar is the upper machine dimension for the laid-flat sealing area. The 5 mm heating strip defines the listed seal width. Side gussets, wrinkles and product contamination can consume usable space, so the filled mouth is the dimension that belongs in a packaging brief.
The ABS body measures 380 × 85 × 50 mm and has a net weight of 0.68 kg. Those figures position UAH12A as a countertop unit that can be planned into retail worktops, demonstration counters or light-commercial prep stations.
Modes change operator control
Wet and dry selection helps the operator choose the intended sealing program. Automatic vacuum sealing handles routine packs, pulse vacuum gives manual control around fragile or moist loads, seal-only closes a bag, and the external hose supports compatible containers.
The product record also lists five vacuum-sealing temperatures. A private-label manual should map each control name to a clear task and keep the same wording on the panel, carton and support page.
UAH12A specification sheet
Rev. 2026.08
The table separates each catalogue value from the commercial reason it matters. It is a selection aid, not a substitute for the ordered specification sheet.
| Specification | UAH12A | Why it matters |
|---|---|---|
| Material | ABS | Defines the listed housing material for finish and artwork planning. |
| Power | 135W | Supports electrical labeling and destination-market documentation. |
| Voltage | 100–240V | Allows one voltage platform with the ordered plug configuration. |
| Suction | 70kPa | States the model’s listed vacuum-pressure capability. |
| Flow rate | 4 L/min ±15% | Adds an evacuation-rate reference with a stated tolerance. |
| Sealing width | 32 cm | Sets the maximum machine span for a laid-flat bag mouth. |
| Heating strip | 5 mm | Defines the listed heat-seal band width. |
| Accessories | Food-sealing vacuum bags; external vacuum hose | Shapes the retail bundle and accessory instructions. |
// 03 — Suction
Does a 70kPa vacuum sealer need 4 L/min?
Yes, the two specifications answer different buyer questions. The 70kPa figure describes pressure capability, while 4 L/min ±15% describes the listed rate of air movement. A useful evaluation records evacuation behavior and retained seal quality on the intended bag, rather than ranking products by kPa alone.
Pressure is the endpoint
A pressure specification helps compare pumps under a defined test method. It does not reveal the bag volume, channel resistance, gasket condition or moment when the operator triggers pulse seal. Those variables decide what a user sees during a real pack.
Flow is the route to that endpoint
Flow matters when the product program includes larger bags or repeated portions with significant headspace. UAH12A’s stated ±15% tolerance is commercially useful because the buyer can turn it into a bounded acceptance criterion instead of relying on an adjective such as “fast.”
A pressure number earns its place on the carton only when the bag format, seal band and operator controls work as one system.

// 04 — Bag fit
Which bag formats fit a 32 cm sealing bar?
A bag fits when its filled, laid-flat mouth sits inside the 32 cm heating span without folds, product residue or stretched gussets crossing the seal zone. Nominal roll width is only a starting point. Packaging teams should measure the loaded mouth and reserve a clean, flat area for the 5 mm seal.
Measure the filled mouth, not the roll label
A gusseted pouch can present more material at the mouth than its front-panel width suggests. Thick portions can also pull the film inward. Lay the filled pack in its sealing position, flatten the mouth and record the widest material span that must receive heat.
Why does a 5 mm strip matter?
The listed 5 mm strip creates UAH12A’s stated seal-band format. Wider is not automatically stronger because film structure, cleanliness, temperature and dwell behavior still matter. The strip width is valuable because it gives packaging engineers a defined physical interface to test.
What do wet and dry modes actually change?
Wet and dry modes select the intended program for different food conditions; they are not a license to pull free liquid through an external-suction path. Pulse control lets the operator watch the liquid front and stop evacuation before moisture reaches the seal zone or hose path.
For soups, loose marinades or other free liquids, a chamber machine is a different equipment class. UAH12A is an external-suction countertop model, so the buyer’s use-case list should distinguish moist solids from free-liquid packs.
// 05 — Comparison
How does this 70kPa vacuum sealer compare?
UAH12A trades a higher listed tier price for a 32 cm bar, 5 mm heating strip, 70kPa suction and 135W input. The fetched UAH41G and UAH57GX siblings use 30 cm bars, 3 mm strips, 65kPa suction and 120W input. Their control layouts and price ladders serve different retail positions.
The comparison turns on workflow
UAH12A suits a program that needs its wider seal span and pulse-oriented controls. UAH41G adds a touch screen and built-in bag cutter. UAH57GX presents a compact control set. All three list wet and dry operation and an external hose, but they are not interchangeable SKUs.
| Model | Power | Suction and seal | Operator format | Lowest listed tier |
|---|---|---|---|---|
| UAH12A | 135W | 70kPa; 32 cm bar; 5 mm strip | Wet/dry, automatic, pulse, seal-only, external hose | $12.90 at 3,000 units |
| UAH41G | 120W | 65kPa; 30 cm bar; 3 mm strip | Touch screen, bag cutter, wet/dry, external hose | $8.30 at 5,000 units |
| UAH57GX | 120W | 65kPa; 30 cm bar; 3 mm strip | Compact, wet/dry, external hose | $8.20 at 5,000 units |
The price cells use each fetched model’s lowest published tier and show the quantity that unlocks it. They are not same-volume quotations. The comparison specifications also come from direct SKU records, not from names in a rotating similar-product feed.
When does UAH12A earn its higher tier?
The premium has a concrete basis when the retail program needs a 32 cm bag mouth, 5 mm seal band or the UAH12A control mix. If those differences do not change the pack or user workflow, a 30 cm sibling may define a more suitable price position.
// 06 — Acceptance
What should a buyer test before a purchase order?
Test UAH12A with the exact film, food condition, filled width, voltage and operator sequence planned for sale. Record evacuation behavior, seal appearance and retention after handling. The goal is not to prove a catalogue number in isolation; it is to establish a repeatable acceptance record for the finished private-label configuration.
Run a seal-retention sequence
Use one defined bag film and load, keep the mouth preparation consistent and run repeated cycles. Inspect each 5 mm seal band for channels, wrinkles, incomplete edges and contamination. Then handle and store the packs under the program’s intended conditions before assessing retention.
Challenge wet-load repeatability
Use the moist solid that represents the target market, not free liquid. Track how close moisture moves toward the seal zone, when pulse control is used and whether the final band remains flat. This reveals both machine behavior and the clarity of the operator instructions.
Inspect controls and accessories
Exercise automatic vacuum sealing, pulse vacuum, seal-only operation, wet and dry selection and the external hose. The inspection record should use the same control names that will appear on the panel and manual, reducing translation and after-sales ambiguity.
// 07 — Fit
Which buyers need this 70kPa vacuum sealer?
The UAH12A vacuum sealer fits distributors, retailers and private-label programs whose loaded bag format needs its wider external-suction layout and whose users benefit from pulse control. It also suits controlled light-commercial portioning. It is not the right equipment class for continuous free-liquid packing or chamber-sealer workloads.
Distributors with wider household bag formats
The 32 cm bar creates a clear merchandising difference from 30 cm siblings. A distributor can pair that dimension with the 5 mm seal strip and external hose in sales training, rather than relying on a generic claim about suction strength.
Private-label programs using one voltage platform
The 100–240V input supports one electrical platform, while plug, panel language, manual, logo, colourway and retail packaging remain market-specific order items. That structure can reduce unnecessary SKU fragmentation without erasing the compliance needs of each destination.
Light-commercial users with controlled portions
Small prep stations may value the compact 380 × 85 × 50 mm body, 0.68 kg net weight and pulse control. Placement should still match the expected cycle pattern, bag preparation and food-safety process. A countertop external unit is not represented here as a continuous-duty chamber machine.
// 08 — Manufacturing
How we manufacture UAH12A
Guilin Prime Household Products Co., LTD builds UAH12A at its Guilin facility and controls tooling, components, finish and line testing. Vacuum Sealer China represents a manufacturer and trading company, not a sourcing agent. The four-step flow below connects OEM choices to pump, seal, compliance and warranty controls.
In-house tooling and private mould work
Tooling and mould control translate the OEM brief into the ABS housing, interface openings and surface finish. Logo, colourway and external details are tied to the same configuration record before packing materials are released.
Pump and PCBA burn-in
Pump and PCBA assemblies move through burn-in before final line release. The purpose is to expose component or control faults before they are hidden inside a packed retail unit.
Quality control and line testing
Line testing covers vacuum response, seal formation and the ordered control functions. Packing follows the accepted panel, accessory and carton configuration so a functioning unit is not paired with the wrong market materials.
CE, RoHS and 12-month warranty
CE and RoHS are the named export compliance marks for relevant configurations, with documents matched to product and destination. UAH12A carries a 12-month warranty, giving the distributor a defined route for manufacturing-related after-sales claims.
// 09 — Commercials
What do the price tiers and cartons mean?
UAH12A has three real catalogue tiers: $13.50 at 100 units, $13.20 at 1,000 and $12.90 at 3,000. Twelve units pack into a carton listed at 0.04953375 CBM and 12.7 kg gross. Buyers should model unit price and freight cube together, because they move through different quantity steps.
Listed UAH12A quantity tiers
The published ladder establishes the starting commercial reference for the unmodified model. OEM artwork, packaging, destination requirements and trade terms can change a quotation, so the purchase order should identify which catalogue tier and which custom deliverables it covers.
| Quantity | Price per unit | Difference from opening tier |
|---|---|---|
| 100 units | $13.50 | $0.00 |
| 1,000 units | $13.20 | $0.30 per unit |
| 3,000 units | $12.90 | $0.60 per unit |
Carton and container data
The logistics record provides exact dimensions and loading quantities for the standard pack. A custom gift box or accessory bundle can alter those values, so freight planning should use the packaging version named in the order.
| Pack item | UAH12A catalogue value |
|---|---|
| Unit net / gross weight | 0.68 kg / 1 kg |
| Product size | 380 × 85 × 50 mm |
| Packaging size | 408 × 85 × 98 mm |
| Units per carton | 12 |
| Carton size / gross weight | 425 × 370 × 315 mm / 12.7 kg |
| CBM per carton | 0.04953375 |
| 20 ft / 40 ft / 40 HQ load | 6,780 / 14,040 / 16,464 units |
Read price and freight together
The lowest unit tier may not create the lowest landed cost for every sales plan. Compare the tier break, carton count, container utilization and inventory turn in one model. That analysis uses published figures without pretending that duties or local delivery costs are universal.
// 10 — Purchase order
What belongs in the UAH12A purchase order?
The purchase order should identify UAH12A through the controlled specification table, then lock the destination plug, panel language, controls, accessories, artwork, packaging, quantity tier, trade terms and agreed bag-and-load acceptance method. Using one reference prevents conflicting figures from being copied into the PO, manual, carton and inspection record.
Electrical and market configuration
Name the destination market, plug standard, rated label, manual language and required compliance set. A broad voltage range does not make plug hardware, labels or local documentation interchangeable, so these items need their own lines rather than a note that says “global version.”
Brand, colour and pack files
Attach the controlled logo file, colour reference, panel copy, carton artwork, manual copy and barcode data. State whether food-sealing bags and the external vacuum hose are included. These details turn OEM or ODM intent into a packable bill of materials.
Trade and delivery terms
The standard B2B framework starts at a 100-unit catalogue tier, with a 15–30-day lead-time range and FOB China as the baseline. EXW or CIF, 30/70 T/T and Alibaba Trade Assurance can be specified where chosen. The final order should state the Incoterm, port, payment milestones and dispatch basis.
// 11 — Food safety
What food-safety limits belong in the manual?
A vacuum sealer removes air and seals a package; it does not make unsafe food safe or replace refrigeration, freezing and process controls. Distributor manuals should separate machine operation from food-handling rules and direct commercial users to the authority that governs reduced-oxygen packaging in their jurisdiction.
Vacuum packaging reduces oxygen; it does not preserve by itself
The USDA Food Safety and Inspection Service explains that vacuum packaging removes air from a package and that oxygen contributes to chemical breakdown and microbial spoilage. This supports a careful benefit statement without promising a universal shelf-life multiple.
Retail and food-service users need process controls
The FDA Food Code treats vacuum packaging as reduced-oxygen packaging and provides a model for retail and food-service controls. A machine supplier should not turn that regulatory framework into one global instruction; operators need the rules adopted by their own authority.
Frozen produce guidance adds a practical use case
USDA’s vacuum-sealing guidance for school nutrition operators discusses frozen produce, freezer-burn reduction and safe practices. It also reinforces the distinction between equipment capability and the operator’s food process, which belongs in training and local procedures.
// 12 — FAQ
What do buyers ask about a 70kPa vacuum sealer?
The FAQ converts recurring catalogue questions into procurement decisions: how to read suction, measure a loaded bag mouth, control moist foods, judge electrical input and define acceptance evidence. Each answer points to an action or limit; the full UAH12A figures remain in the specification and comparison tables above.
What does 70kPa mean on a vacuum sealer?
Is a 32 cm seal bar wide enough for retail bags?
What is the difference between wet and dry vacuum sealer modes?
Is 135W enough for a vacuum sealer?
What should an importer test before ordering UAH12A?
// 13 — Conclusion
What evidence should decide the UAH12A order?
The order should be decided by evidence from the intended pack, not by repeating the catalogue. First establish bag fit and a clean seal, then record evacuation and retention under the planned operator sequence. Only after that result should the buyer choose the configuration, quantity tier and purchase-order controls.
The UAH12A vacuum sealer belongs on the shortlist when that evidence supports the retail format and the ordered controls reduce operator ambiguity. Carry the accepted film, load, market configuration and pack files into one controlled purchase order; use the specification and comparison tables above as the numerical record.
