Letterbox-Sized Packs

Letterbox-Sized Packs

Plenty of online orders are small, light and flat, so they do not require a big box. Letterbox-sized packs UK brands order are small corrugated boxes that go through a standard letterbox. Sellers use them for small beauty items, prints and accessories, and for flat sachets such as facial mask packaging pouches. At Hale Path Packaging, we make letterbox packaging UK buyers can order in custom sizes, board and print.

Letterbox Packs UK Sellers Use to Put Orders Through the Door and Into Customers' Hands

Letterbox packs are shallow corrugated boxes with a tuck-in lid. You’ll see them sold as letterbox-sized boxes, letterbox-size postal boxes or flat mailers. Because they’re slim, they go straight through the door. Nobody has to wait in for a courier. Open the lid and a printed note or product card is the first thing the customer sees. Customers notice that. Beauty sellers shipping pencils and liners often begin with our eyebrow pencil boxes and pack those inside the letterbox pack. 

Which Board Should a Letterbox Pack Use?

Sorting machines and mailbags are rough on a flat pack. The board needs to be slim enough for the slot, but strong enough to keep its shape. For letterbox size packaging, we use fine-flute single-wall board, which stays thin but doesn’t bend easily. Kraft gives a natural look, and white board shows colour better. A tea blender in Cornwall posts loose-leaf sample sets in 20 mm letterbox packs. Each lid carries a short brewing guide. Customers often mention that guide in their reviews, and many go on to order the full-size tins.Loose items need to stay put. A card insert holds flat pieces in place. Powders and small sachets do better in an inner 3-side seal aluminium pouch, which keeps them contained without adding depth.

Letterbox Size Boxes UK Dimensions Explained, From Standard Letter Box Size cm to Large Letterbox-Sized Packs UK

Postal rules set the size. The Large Letter size limit is 35.3 x 25 x 2.5 cm, and the weight limit is 750 g. Go thicker or heavier, and the parcel is charged as a small parcel. If you’re hunting for letterbox boxes that will accept, treat those figures as your ceiling for the external size. People also search for the standard letterbox size cm. In reality, home letterboxes vary from door to door. The postal limit is the safer guide for letterbox sizing. For postage, the letterbox UK size that counts is the Large Letter band. Large letterbox-sized packs UK sellers order tend to suit A4 prints, thin books and folded tops. Check current postage rates before you settle on a size. Small cosmetics need very little depth, and our concealer boxes are one example. Two checks help before you order:

  • Keep the pack 2 to 3 mm under the 25 mm limit. Then push a template through a slot to run a slot test.

Printing and Finishing That Make a Slim Pack Look Like a Gift Worth Opening

The lid is wide and flat, which leaves plenty of space for your logo. We print on the outside, the inside or both. Whiteboard suits full colour artwork. On kraft, a one-colour logo is usually enough. Add a matt or gloss varnish if you like the print to reach the customer without scratching off. Our letterbox packaging boxes UK buyers order can match the lid to their custom blush packaging, so the whole order looks like one range. The inside of the lid is free space too. You can print a thank you note, usage tips or a discount code there without adding any thickness. Eye makeup lines can carry the same artwork over from their kajal boxes.

Why Small Brands and Trade Buyers Order the Best Letterbox-Sized Packs UK-Wide From Hale Path Packaging

We manufacture these packs ourselves, so the cut, the crease and the print stay in our hands. Small brands get a pack built around the product, with no wasted space. Cheap letterbox-sized packs UK buyers want usually come down to postage. A pack that keeps every order inside the Large Letter band saves money on each parcel. Subscription sellers can pair it with our candle kit boxes for wax melt and tea light sets.

Trade buyers get steady specs, and repeat orders match the first one. Flat pack shipping keeps pallets compact and storage simple. Our team can propose a board and pack size once they know your product depth and monthly volume. Sample size vials fit this format too, and our serum boxes suit the next size up.

Frequently Asked Questions

What's the thickest a letterbox pack can be before it counts as a small parcel?

The outside must stay at 25 mm or under, and the whole pack must weigh no more than 750 g. Go over either figure and it's charged as a small parcel.

Do you offer free letterbox-sized packs UK sellers can try?

Packs are made to order and priced per run. For samples, ask our team before you place a full order.

How can I cut the postage cost of a letterbox pack?

Postage follows size and weight, so keep both low. Choose the slimmest pack that fits your product and keep the contents light. A snug fit helps too, because it takes a few millimetres off the depth.

Which board protects best in a slim pack?

Fine flute single-wall board is the best fit, as it stays thin and stiff. Add a card insert if the items bend easily.

Can one pack hold more than one product?

Yes, if everything lies flat and the stack stays under 25 mm. A card divider stops the items sliding around in the post.

Will the lid stay shut in the post?

The tuck flap holds the lid shut. For valuable contents, put a sticker seal over the flap as well.

Which letterbox pack fits A4 prints?

Leave a little extra room inside so the print drops in without being seen, and keep the outside depth below 25 mm.

Are letterbox packs recyclable?

Yes, plain board printed with water-based ink can go in your normal cardboard recycling. Peel away any plastic window or foil before you recycle it.
