Custom Shipping Envelopes

Custom shipping envelopes made to your size with printed branding, thick card, peel-and-seal closures, tear strips and optional insert pockets.

Custom Envelopes for Shipping

Custom shipping envelopes are a smart choice when your product is too flat for a box but deserves more than a standard paper envelope.

They work well for cards, photographs, prints, documents, vouchers, product samples, promotional packs, stationery, lightweight merchandise and other slim products that need to arrive neat and professionally presented.

Custom Packly can make the envelope to the size your product actually needs, rather than making you choose from standard postal sizes.

You can add branded printing, thicker card, a peel-and-seal flap, tear strip, matte finish or an extra pocket for a card or leaflet.

For products that need more depth and protection, our custom mailer boxes may be a better fit. For flatter products, a custom shipping envelope keeps the package compact and easy to handle.

Made to Your Size

Standard envelopes are convenient until the product does not fit them properly.

A made-to-size shipping envelope can be created around your actual contents, whether that is a stack of cards, printed artwork, a small textile item, product literature or a mix of flat pieces.

A closer fit has several advantages.

It looks neater, reduces unnecessary empty space and helps stop the contents sliding around inside.

It can also make packing easier because staff are not trying to squeeze products into an envelope that is too tight or fill unnecessary space in one that is too large.

If you are still deciding what packaging best suits your product, How to Choose Custom Packaging for Your Product covers the main decisions worth checking first.

Peel, Seal and Send

The closing flap can include a peel-and-seal adhesive strip.

Your packing team simply loads the contents, removes the backing strip and presses the flap closed.

There is no need to add separate tape to every order.

For businesses sending regular parcels, that small change can make packing faster and keep the finished parcel looking cleaner.

Peel-and-Seal Flaps

A peel-and-seal flap is useful for ecommerce orders, printed mailouts and recurring customer packs.

The adhesive is already added during production, so the envelope is ready to close when it reaches your packing bench.

The flap size and adhesive area can be adjusted to suit the envelope dimensions.

Easy Tear Opening

A tear strip gives the customer a clear place to open the package.

Rather than tearing through the top edge or reaching for scissors, they can pull the strip and open the envelope cleanly.

This works particularly well when the same envelope also has a peel-and-seal flap.

Your team gets quick packing. Your customer gets quick opening.

Add a Card Pocket

Not everything needs to sit loose inside the same compartment.

A small pocket can be added when you need to include an information card, instruction sheet, voucher, thank-you card, flyer or another printed piece.

The pocket keeps that item separate from the main product and can make the contents feel much more organised when the customer opens the envelope.

For example, the main section could hold a card set or small product while the front or inside pocket holds an information card.

We can adjust the pocket depth and opening so the card stays secure but is still easy to remove.

Choose the Right Card

The material should match what you are sending and how much stiffness you want.

Thicker Card

Thicker card is a good choice when you want the envelope to feel more substantial than normal stationery.

Around 300–350 GSM can work well for many printed shipping envelopes, depending on the size and contents.

It gives the envelope more firmness while still allowing it to fold and close neatly.

For heavier or larger products, we can recommend whether you should move to a stronger mailing style instead of simply making the card thicker.

White Card

White card gives bright artwork and full-colour printing a clean starting point.

It suits brands using photography, illustrations, strong colours or detailed packaging artwork.

Kraft Card

Kraft creates a simpler, natural look.

It works particularly well with black print, darker colours and minimal branding.

If you are deciding between different materials and finishes, our customisation section gives a wider view of what can be produced.

Print It Your Way

Custom shipping envelopes do not need to look like ordinary postal supplies.

The front, back and flap can all become part of the presentation when the design calls for it.

Branded Outside Print

Add your logo, colours, pattern, product message or campaign artwork to the outside.

For envelopes going directly through delivery networks, it is sensible to leave enough clear space for shipping labels and any information your fulfilment team needs to add.

Inside Printing

Inside printing can create a second brand moment after the envelope opens.

A simple message, colour or pattern can often work better than filling every surface with artwork.

Full-Colour Printing

Full-colour printing is well suited to photography, illustrations, gradients and artwork using several colours.

For simple branding, a more restrained print can also look strong and may keep the design cleaner.

Finishes That Make Sense

The finish should support the look you want rather than being added simply because it is available.

Matte Finish

Matte lamination gives the envelope a smooth, understated finish.

It suits premium mailouts, branded product packs and designs where you want less shine.

Gloss Finish

Gloss creates more shine and can make colours look more vivid.

It can work well for bold branding and promotional mailouts.

Foil and Spot Details

Foil, embossing, debossing and spot UV can be considered when you want a logo or small design detail to stand out.

For everyday ecommerce shipping, clean printing and good material will often do more for the presentation than adding too many finishes.

What Can You Send?

Custom shipping envelopes work best for products that are relatively slim.

They can be used for:

Art prints
Photographs
Cards and card sets
Vouchers
Certificates
Booklets
Small clothing items
Stationery
Promotional packs
Membership packs
Welcome packs
Product samples
Event materials
Lightweight accessories
Printed marketing kits

For heavier, fragile or bulky products, a box will usually give better protection.

Our shipping and postal packaging covers stronger choices for products that need more protection during delivery.

Envelope or Mailer Box?

The decision usually comes down to thickness and protection.

A shipping envelope works best when the product is flat, lightweight and does not need thick side walls.

A mailer box is better when the product has more depth, several loose pieces or needs extra protection around the corners and sides.

For example, a printed certificate pack may suit an envelope perfectly.

A candle, skincare set or small electronics bundle is more likely to need a box.

The aim is not to use more packaging than necessary. It is to use enough packaging for the product to arrive properly.

Envelope or Mailing Box?

Custom mailing boxes are useful when you like the idea of compact postal packaging but need more room around the contents.

They can hold thicker packs, product bundles and items that need greater protection.

A custom shipping envelope stays much flatter.

If your product is only a few millimetres thick, moving straight to a mailing box may add unnecessary size.

Envelope or Postal Box?

Custom postal boxes suit small ecommerce parcels that need the protection of a box without moving to a large shipping carton.

Choose a postal box when the item has depth or needs better corner protection.

Choose a shipping envelope when the product is flat and the main priorities are a clean fit, quick packing and branded presentation.

Plan the Opening First

The tear strip and adhesive should be considered before the artwork is finished.

That avoids placing important logos, wording or images across areas that need to fold, seal or tear.

The same applies when there is a card pocket.

Once we know where the flap, adhesive strip, tear line and pocket need to sit, the artwork can be placed around them properly.

If you already have artwork, we can work with it.

If not, Custom Packly can help with the packaging design, dieline and 3D mockup.

Keep Packing Easy

A good envelope should be easy for your team to use every day.

The opening needs enough room for the product to slide in without catching.

The pocket needs to be easy to load.

The peel strip needs to be easy to grab.

The finished parcel needs to close without staff pressing, bending or forcing the contents into place.

These details become much more important when you are packing hundreds or thousands of orders.

Sometimes adding a few millimetres makes packing noticeably faster without making the finished envelope look oversized.

Keep Delivery in Mind

A shipping envelope can add firmness and presentation, but it should still match the product.

If the contents can easily bend, crack or break, the envelope may need to be paired with extra protection or replaced with a stronger mailer.

Art prints, photographs and certificates may need more stiffness than clothing or paper inserts.

A soft textile item may tolerate more movement than a printed piece that must arrive perfectly flat.

If protection is the main concern, it is worth comparing the envelope with a postal box before placing the order.

What Changes the Price?

Custom shipping envelope pricing depends mainly on the size, quantity, material, printing and added features.

A simple printed envelope costs differently from one using thicker card, matte lamination, an adhesive strip, a tear strip and an extra pocket.

Quantity can also make a large difference to the price per piece.

If you know that you may eventually need 500 or 1,000 units, it can be useful to compare those quantities with the first order rather than pricing only one quantity.

Our breakdown of custom packaging costs in Australia covers why size, quantity, materials and finishing can move pricing up or down.
