Custom packaging is the set of branded boxes, shipping mailers, and interior add-ons that turn a standard delivery into a recognisable brand experience.

A complete custom packaging system covers three layers: the outer container, the shipping format, and the finishing details inside, each carrying consistent visual identity from the doorstep to the last item removed. This guide covers all three layers, product by product, with practical advice on matching the investment to the occasion.

The moment a parcel arrives at a customer’s door, a team member’s home address, or a client’s office is a brand moment. It is often the most concentrated and most personal physical interaction a brand gets with a recipient.

What the outside of the box communicates, what the inside looks like when opened, and what the materials feel like in the hands all shape whether the recipient experiences something considered and quality-led or something functional and forgettable. The same thinking that goes into choosing eco-friendly business gifts deserves to extend to the packaging it arrives in.

Why Packaging Deserves the Same Design Attention as the Products Inside

There is a tendency in merch and gifting programmes to treat packaging as an afterthought. Products are selected carefully, budgets are allocated to the items inside the box, and then a standard mailer is chosen by default because the packaging question feels like a logistics decision rather than a brand decision. The recipient experiences it differently.

The commercial case is well documented. McKinsey reports that views of YouTube videos with unboxing in the title surpassed 25 billion in 2024, which means the experience of opening a package has become a public, shared, social moment for millions of consumers. The packaging is not incidental to that moment. It is the moment.

Sustainability compounds the case. A joint McKinsey and NielsenIQ study of five years of US sales data found that products making ESG-related claims averaged 28 percent cumulative growth over the period, compared with 20 percent for products that made no such claims. And according to NIQ’s 2023 CPG Sustainability Report, 92 percent of shoppers say sustainability is important when choosing a brand. Choosing sustainable packaging materials is one of the most visible ways to act on that expectation.

When a merch kit, a client gift, or an onboarding pack arrives in packaging that communicates care and quality, the recipient’s expectation of what is inside rises before the box is opened. That tone affects how the products inside are received, how long they are kept, and how likely the recipient is to share the moment. With that in mind, here is the complete custom packaging range, organised by category.

Custom Boxes: The Branded Container That Sets Every Expectation

The box is the first physical impression of the brand in any gifting or fulfilment context. The quality of the box communicates the quality of everything inside before the recipient has seen a single product.

1. Plain Box

Not every programme needs full print from day one, and forcing that investment too early is how packaging budgets get burned before the products are even chosen. The Plain Box in Kraft or White is the flexible, quality base for gifting, onboarding kits, and e-commerce fulfilment at an accessible price point, with production in approximately 4 business days. Pair it with the Sticker for Plain Box further down this list and it becomes a branded delivery experience without the lead time of a printed alternative.

2. Printed Box

A single or two-colour logo stamped on a Kraft surface has an artisanal, considered look that suits lifestyle, food, wellness, and creative brand identities naturally. The Printed Box is the step up from the plain option for programmes where the packaging needs to carry a visible brand mark without full-colour printing, and it produces in approximately 10 business days. It creates immediate branded impact at the doorstep with modest investment.

3. Full Colour Box

Launching a campaign where the artwork matters as much as the logo? The Full Colour Box carries full-colour print on the exterior surface, allowing the complete visual identity, campaign artwork, or event-specific design to be expressed rather than approximated in one colour. Crafted primarily from recycled materials and fully recyclable, it reads as deliberate rather than standard, with production in approximately 18 business days.

4. Double Sided Printed Box

There is a meaningful difference between a box that is branded on the outside and one that reveals a second branded environment when opened. The Double Sided Printed Box, with full-colour print on both the white exterior and the Kraft interior, is the premium option for client gifting, milestone recognition, and any programme where the unboxing experience is as important as the products inside. Made in the EU, with production in approximately 16 business days. When the interior is as considered as the exterior, the recipient experiences a continuous brand statement from arrival to the last product removed. It is the natural container for the kind of client appreciation gifts that are meant to strengthen a relationship.

Shipping Mailers: Practical Branded Delivery Formats

Shipping mailers cover flat-pack and flexible delivery formats for e-commerce fulfilment, apparel, and light-product gifting where a rigid box is not the right fit. They carry the brand at every doorstep moment across the sizes and weights they serve.

5. Kraft Mailer Bag

Sustainability claims lose credibility fast when the parcel arrives in virgin plastic. The Kraft Mailer Bag is made from 100 percent FSC-certified recycled materials and is home-compost friendly, decomposing entirely within 180 days. For brands whose identity is explicitly built around environmental responsibility, it communicates that the commitment extends into the fulfilment infrastructure rather than existing only in product descriptions.

6. Preprinted Mailer Bag

Where the Kraft option leans on material honesty, the Preprinted Mailer Bag leans on efficiency. These reusable stock recycled mailers are the economical, adaptable choice for shipping a wide range of products at volume, with a fast production time of approximately 6 business days. Pair them with a branded sticker or insert card to create a brand moment inside without exterior print investment on every order.

7. Plain Mailer Bag

Shipping soft products at volume and need something light, tough, and reusable? The Plain Mailer Bag is a durable, reusable mailer designed to protect products in transit while carrying a full branded exterior, with production in approximately 7 business days. For fashion brands, apparel distributions, and any programme where the product format allows a flexible bag rather than a box, it delivers exterior brand visibility at the doorstep without the production complexity of a rigid printed alternative.

8. Metallic Zip Handle Bag

The Metallic Zip Handle Bag is the premium boutique packaging format for luxury gifting, high-end retail distributions, and the kind of premium client relationship moments where the carry bag itself communicates luxury positioning rather than functional delivery. Available in metallic finish with a secure zip closure.

For gifting programmes at the premium and luxury tier, a metallic zip bag communicates investment in the presentation of the gift at a level that communicates the quality of the relationship being recognised before the bag is opened.

Packaging Add-Ons: The Details That Turn a Package Into an Experience

Add-ons are the interior elements, inserts, and finishing details that determine the quality of the unboxing once the outer box or bag has been opened. These are the details that separate a well-curated kit from a box of products.

9. Sticker for Plain Box

A custom printed box is not always in the budget or the timeline, and it does not need to be. The Sticker for Plain Box is the most cost-efficient way to transform a plain shipping box into a branded delivery experience, applied to the exterior for immediate visual impact, with production in approximately 8 business days. For teams holding plain box inventory, it is the most accessible branded packaging upgrade available.

10. Stickers

Unlike the box-specific sticker above, these travel anywhere. Die-cut contour Stickers with durable adhesive apply cleanly to boxes, mailers, tissue seals, and the products themselves, making them the most flexible branding element in the range. Ordered once, they extend a single design across every packaging format a programme uses.

11. Tissue Paper

The first thing a recipient sees when the lid comes off is not a product. It is the interior layer. Custom Tissue Paper sets the visual tone of the unboxing before any item is visible, creating a branded colour and design context that communicates curation in the first moment of opening, with production in approximately 8 business days. For programmes where the interior experience is part of the brand strategy, it is the element with the most immediate impact.

12. Wood Wool Filling

Efficient packing and genuine curation are not the same thing, and recipients can tell the difference instantly. Natural Wood Wool Filling creates a nest-like interior that makes every product feel individually placed and individually valued. It is sustainable, biodegradable, photographs beautifully in social content, and produces in approximately 7 business days.

13. Paper Filling

Working with a specific brand palette? Recycled coloured Paper Filling, made from 80 percent recycled materials, lets the interior packaging be matched to the brand’s own colours, carrying the palette into the unboxing as effectively as any printed element. It also keeps items securely in place during transit, which makes it as practical as it is visual.

14. Paper Bubble Wrap

Fragile items and sustainability goals used to be in tension. Paper Bubble Wrap resolves it: a recyclable, plastic-free kraft alternative to conventional bubble wrap, with a shock-absorbing embossed structure and flexible layers that give delicate products genuine protective cushioning in transit. Production is approximately 7 business days, and it signals environmental commitment through the most functional part of fulfilment.

15. Card

Products communicate quality; a written message communicates intent. The premium Card in A6 with a matte finish is the personalised element of a gift kit that tells the recipient some one considered them specifically, rather than assembling an identical kit for everyone. For milestone recognition, long-service awards, and new hire welcome moments, it carries the warmth of the occasion in a format no product can replicate. It is a natural fit inside onboarding packs where a personal note from a manager makes the first day memorable.

How to Build a Coherent Branded Packaging System

The strongest packaging programmes are not built from individually chosen products. They are built as systems where every format, from the outer box to the interior tissue to the card inside, carries consistent visual identity and communicates one quality standard.

For a premium unboxing, a Double Sided Printed Box layered with branded tissue paper, wood wool filling, and a personalised card creates an experience where each stage of opening reveals a new branded detail. For high-volume distributions, a Kraft or Preprinted Mailer with a sticker and an insert card delivers a considered, sustainable experience at a unit cost that scales.

Match the investment to the moment. Premium recognition and luxury business gifts deserve premium packaging; event distributions need an efficient system that still communicates identity at accessible unit costs. The mistake to avoid is a mismatch in either direction: a premium gift in an anonymous mailer undersells the gesture, while over-engineered packaging on low-value giveaways reads as waste.

Frequently Asked Questions About Custom Packaging

What is custom packaging?

Custom packaging is branded boxes, mailers, and interior add-ons designed to carry a company’s visual identity through the delivery and unboxing experience. It typically spans three layers: the outer container, the shipping format, and finishing details such as tissue paper, fillings, and cards.

How do I decide between a plain box with a sticker and a fully printed custom box?

Choose based on lead time, volume, and the importance of the recipient moment. A plain box with a branded sticker works well for high-volume distributions on short timelines where speed and cost efficiency are the primary constraints. A full colour or double sided printed box is the right investment for milestone gifting, premium client relationships, and moments where the packaging itself signals the significance of the occasion.

What packaging combination creates the best unboxing experience?

The most consistently well-received combination pairs a double sided printed box with wood wool or coloured paper filling, a branded tissue paper layer, and a personalised card. This creates a layered experience where each stage of opening reveals a new branded detail, building anticipation and communicating care at every step.

How does sustainable packaging communicate brand values?

Sustainable packaging expresses environmental commitment through operational choices rather than claims. Research from McKinsey and NielsenIQ found products making ESG-related claims averaged 28 percent cumulative growth over five years versus 20 percent for products without them, and NIQ reports that 92 percent of shoppers say sustainability is important when choosing a brand. Kraft boxes, recycled paper fillings, compostable mailers, and paper bubble wrap all make that commitment tangible at the doorstep.
