Sealock vacuum compression bags reduce the packed volume of clothes by up to about 70% and keep it that way. Each bag is made from TPU laminated fabric with high-frequency welded seams and a full-length sealed zipper, so there are no needle holes for air to leak back through. Choose a roll-up bag with a one-way valve, a bag with a hand pump, or a bag with a built-in USB-C electric pump. All three are available for OEM and private label from 300 pieces, with custom sizes, colours, logo and retail packaging, made in China or Vietnam.
Manual vacuum compression packing bag with a screw-type air valve and an included hand pump. Occupies the position between press-by-hand and battery-powered compression: full evacuation performance with no electronics, no charging cycle, and no lithium battery to declare or certify for air freight. High-frequency welded TPU body, full-length sealed waterproof zipper, welded transparent viewing window, and moulded grip tabs on both sides for holding the bag steady during evacuation. 48 × 29 × 10 cm, approx. 13.9 L, 0.18 kg, in white or black.

Vacuum compression packing bag with an integrated USB-C rechargeable electric pump — no separate pump unit to lose or forget, which is the single most common failure point in this category. High-frequency welded TPU body with a full-length sealed waterproof zipper, transparent viewing window, D-ring hanging loop, and bound edge finishing. Digital display shows compression countdown; screw-down waterproof cap seals the pump housing when not in use. 42 × 29 × 11 cm, approx. 13.4 L, 0.2 kg. Splash, dust, and damp resistant; not rated for submersion. MOQ 300 pcs FOB Guangdong, samples in 7–15 days. -->
Reusable vacuum compression bag in high-frequency welded TPU with a full-length sealed waterproof zipper and a centre-mounted one-way valve. No pump or power required — hand pressure compresses, and the valve holds. Welded seams rather than heat-sealed film give the cycle life that cheap compression bags lack, and the sealed construction means the bag also functions as a dry bag for wet kit. Three sizes: 38 × 27 × 14 cm (14L), 46.5 × 31.5 × 14 cm (20L), 53.5 × 38.5 × 16 cm (33L), 150g each, black. Verified by 24-hour vacuum retention and air-leak determination. Nested retail sets, colour-coded sizing, and transparent panels available as ODM. MOQ 500 pcs, samples in 7–15 days.
Start with how the air comes out. A roll-up bag has a one-way valve and needs no pump: you roll or press the bag and the air leaves. It is the lightest option and the simplest to sell as a nested set of three sizes. A hand-pump bag removes more of the air trapped in down and fleece and has no battery, so it ships as ordinary cargo. A bag with a built-in electric pump compresses at the press of a button in about 15 seconds and suits travellers who repack every day.
Then check the size against the luggage. A compressed bag is a flat, stiff slab, so it should lie flat inside the case without bending. Bags up to about 48 × 31 cm fit a carry-on; larger bags of around 53 × 38 cm suit checked suitcases and duffels of 60 litres and above. Finally, look at what keeps the vacuum in: a sealed zipper that is either fully open or fully closed, a valve cap that screws down onto a gasket, and welded seams. Thin film bags with press seals and heat-sealed edges are cheaper, but they are the ones that fill with air again overnight.
We develop compression bags for travel, luggage and outdoor brands. Sizes can be matched to the inside of your own suitcases or duffels, the TPU can be colour-matched to Pantone, and a clear window, size labels and printed packing instructions can be added. Logos are applied by silk screen, heat transfer, welded patch or custom zipper pull. Sets are packed in a colour box, header card or gift box. MOQ is 300 pieces for the hand-pump and built-in-pump bags and 500 for the roll-up set, samples take about 7–15 days and bulk production about 30–45 days. Our sewing lines make matching travel bags and pouches to the same standard, so a full travel set can come from one factory.
Every order passes through incoming material inspection (IQC), in-process checks during welding and assembly (IPQC) and final inspection (OQC), with SGS or QIMA third-party inspection available on request. Welded seams are tested for tensile and bonding strength at the valve mount, window frame and zipper ends. Finished bags go through a load test of 1,500+ cycles and a 3,000-cycle zipper test; built-in pumps are run through pump and battery charge cycles. Every compression bag then goes through our customer inspection procedure: unboxing, vacuum extraction, a 24-hour static rest and air-leak determination.
Up to about 60–70% of the volume of soft, bulky clothes such as knitwear, fleece and down. They save space, not weight, so weigh the packed case before a flight.
No. Roll-up bags compress by hand, and the pump models carry their own hand pump or built-in electric pump.
Yes, in both carry-on and checked luggage. Security may ask to open one. Bags with a built-in pump contain a small lithium battery and should travel in the cabin, switched off.
300 pieces per style for the hand-pump and built-in-pump bags and 500 for the roll-up set.
Price depends on the compression method, size, number of bags per set, logo method, packaging and order quantity. Send us your specification and target quantity for a quotation.
Yes, by silk screen, heat transfer, welded logo patch or custom zipper pull, with colours matched to Pantone.
