Poly bags for hoodies are sized to the hoodie as it is folded, with depth for the hood and cuffs, so the zip seal closes flat rather than straining. Velocity Wear makes frosted, resealable zip-seal bags printed with your logo, with size stickers and a hang hole, from 50 bags per design, and confirms the dimensions for each heavyweight style in your quote.

How do you fold a hoodie to fit a poly bag?

Fold it into an even rectangle with the hood's bulk spread out, not bunched at one end. A consistent fold matters as much as the bag, because the bag is sized to it. A method that works for most hoodies and sweatshirts:

  1. 1Lay the hoodie face down and smooth the back flat.
  2. 2Fold each sleeve across the back, cuffs pointing down.
  3. 3Fold the sides in to the width you want, ideally around a folding board.
  4. 4Lay the hood flat onto the back instead of leaving it standing up behind the neck.
  5. 5Fold the body in half or in thirds from the hem up, depending on the bag you are working to.
  6. 6Turn it over so the chest print or logo faces the front of the bag and shows behind the frosted film.

Use the same fold on every piece and describe it with the order, because a bag sized to one fold is wrong for another. Garments made in our hoodie range are folded to the agreed fold before bagging.

Why does the zip seal matter more on heavy garments?

A zip seal, the pair of interlocking plastic tracks that press shut along the top of the bag, holds best when it closes without tension. A heavyweight hoodie that fills its bag to the brim pulls on those tracks whenever the bag is lifted or stacked, and a seal under constant strain can work open. The answer is clearance. Our zip-seal garment bags are sized so the folded garment sits below the zip track, with enough depth that the film is not stretched tight across the hood.

Before closing, smooth the bag from the bottom up to push out trapped air, so it lies flat and nothing presses on the seal from inside. To see how the seal behaves around your heaviest piece, one or two samples cost £150, credited against the bulk order, as explained on the samples page.

Where should the size sticker go on a bulky bag?

On a flat part of the face, in the same place on every bag. A hoodie bag bulges where the hood and cuffs sit, and a sticker placed over that curve wrinkles, lifts at the edge or reads at an angle. Pick a flat corner away from the hood, keep it clear of the printed logo, and use that position across the whole size run, so a picker facing a shelf of stacked hoodies knows where to look.

Can jackets go in poly bags?

Yes, with more preparation. Close every zip, button and popper before folding, lay the collar flat, fold the sleeves back across the body and fold in half, so the hardware sits inside the fold instead of pressing against the film. Jackets are usually the deepest items a brand bags, and the collar and zip pulls decide that depth. The same goes for outerwear from our jackets range and for denim jackets with metal buttons: each style gets its own bag size, and garment-by-garment measuring is in polythene bag sizes for clothing.

Sending a heavyweight bag order

Start with the heaviest, largest piece, because that sets the deepest bag. In the enquiry form, list each style with its fold, attach the logo file and your size breakdown for the stickers, and add the number of bags per design with the delivery country and the date you need them. For your own garments, send the largest size of each style. The custom polythene bag range has the specification, and the printed polythene bag guide covers the rest of the range.

FAQ

Quick Answers

Common questions about packaging — answered.

A heavyweight hoodie rarely fits a bag sized for a t-shirt: the hood, cuffs and thicker fabric add depth, so the zip seal strains, the hood gets crushed and the seal can pull open. Velocity Wear sizes each bag to the folded hoodie, with depth for the hood, and confirms the dimensions per style in the quote.

A jacket packs best fastened, with zips and poppers closed, the sleeves folded back and the collar laid flat, then sealed in a garment bag deep enough for its hardware and sent inside an outer mailer or box. Velocity Wear sizes resealable printed bags to each folded jacket style, adds size stickers and confirms the dimensions in the quote.

Sweatshirts and hoodies of the same fabric weight often fold to a similar width, but the hood adds depth at one end, so a hoodie usually needs a deeper bag than a crew-neck sweatshirt. Velocity Wear sizes each polythene bag to the folded style and says in the quote whether two styles can share one bag size.

Pressing the air out of a hoodie bag before closing the zip seal makes the bag lie flat, stack neatly and take up less room in a carton, and it stops trapped air pushing on the seal when bags are stacked. Smooth the bag from the bottom towards the open top, then close the zip along its full length.
