Carton Sealing Machine for Garments and Textile

Why are garment cartons different from other loads?

Garments are light and soft. A carton of folded shirts weighs little for its size, so the seal rarely fails from weight. It fails for other reasons:

• Over-filling. Packers fit one more polybag into the box, the top bulges, and the flaps no longer meet.
• No firm base for the tape. Soft contents give way under the top head, so the tape can wrinkle unless the box is filled evenly.
• Buyer rules. Export buyers often specify the carton size, board, tape width, label position and sometimes straps.
• Marking space. Shipping marks, PO number, carton number and barcode labels all compete for the same faces as the tape.

A carton sealer for textile and garments work therefore has to give a flat, centred seam on a soft box, and leave the marking areas clear.

Overfilled soft cartons: how do you get a flat seal?

Most garment seal complaints start before the machine. A carton that bulges by even a finger's width pushes the seam apart, and tape laid across a gap between flaps peels from the middle.

1. Pack to a count that fits. Fix pieces per carton for each style so the top closes flat without pressing.
2. Press bundles before boxing. Bundling folded garments under even pressure, often with a strap, makes them take less room and keeps the top flat.
3. Set the top head lightly. On a semi automatic sealer the top head should just touch the closed box. Lowering it to squash a bulge creases the tape and crushes corners.
4. Close flaps edge to edge. The two long flaps should meet in a straight line along the centre before the carton enters the belts.

Once these are right, a fixed-size sealer gives the same flat seam on the last box of the shift as on the first.

Which garment carton suits which PackForge model?

Rates exclude 18% GST; model names link to full specifications.

Many export garment cartons are longer than 500 mm. The 102TU lists its limit as width and height, not length, but a carton that long falls outside the 5050J range. Check your buyer's carton size against the table before ordering. All prices are on the carton sealing machine price page.

Export H-seal: when a buyer's specification asks for it

Some export buyers ask for edge taping on top of the centre seam, giving an H shape on each face. It closes the corners of the seam and makes a carton hard to open without leaving marks, which matters on a long sea or air journey through several handlers.

There are two ways to meet the rule:

• Machine centre seam, edge strips by hand. A fixed sealer tapes top and bottom; a packer adds the end strips with a dispenser. This works for modest export volumes and for cartons longer than 500 mm.
• 5050J edge sealer. One machine lays the centre seam and the edge strips, top and bottom, for packs of 2.5 to 30 kg. It needs air at 0.5 to 0.6 MPa and takes 60 or 76 mm tape.

Read the specification carefully: some buyers fix tape width and colour as well as the pattern. More on export packing is on carton sealing machine for export.

Carton marking space: how do you keep tape off the shipping marks?

A garment export carton carries a lot of print: buyer name, PO and style numbers, colour and size breakdown, carton number, gross and net weight, and often a barcode label in a fixed position. Tape that runs over any of it causes trouble at the buyer's warehouse.

• Centre seam only: the tape covers the flap joint on top and bottom, plus a short leg on each end face. Keep end-face marks clear of the top and bottom edges by more than the leg length.
• H-seal: the edge strips run along the ends of the top and bottom faces. Marks near those edges need to move inward.
• Tape width: 48 mm tape leaves more of the top face free than 3-inch tape. Use the narrower width unless the buyer or the carton weight calls for wider.
• Label position: if the buyer fixes it, check one sealed sample against the specification before bulk packing starts.

Should garment cartons be strapped as well?

Usually, a well-filled garment carton travels fine on tape alone, because it is light. Strap comes in for three reasons:

1. The buyer's packing note asks for straps, often two, in set positions.
2. Cartons will sit at the bottom of a tall stack in a container or godown.
3. Bundles of folded garments are compressed before boxing to save carton space.

Soft cartons crush easily, so keep strap tension low and use edge protectors on printed board. A semi automatic strapping machine beside the sealer handles both carton strapping and bundle pressing.

Home textiles and made-ups: light but bulky

Bed linen, towels, curtains and other made-ups usually leave in cartons; blankets, quilts and rugs are often baled instead. The carton side follows the same rules as garments: pack to a count that closes flat, and keep marks clear of the tape. The bale side is a strapping job, where the strap holds the compression in place for the whole journey.

Panipat is the best-known example in North India, with blankets, rugs and made-ups going across the country and abroad. Units there often need a sealer for cartons and a strapper for bales on the same floor. See packaging machines for Panipat.

Changing styles, changing carton sizes

Garment units pack many styles, and each buyer or size set may come with its own carton. On a fixed-size sealer, each change means resetting width and height. With two or three cartons a day, that takes little time. When the carton changes many times in a day, packers start taping by hand again.

Count how many carton sizes really run for more than a short while each day. With three or fewer, a fixed sealer is the cheaper choice. With more, look at the self-adjusting random sealer on our main carton sealing machine page, which needs compressed air. Garment brands shipping single orders to marketplaces should also read the carton sealing machine for e-commerce page.
