Varnish
A transparent finishing layer available in gloss, satin, or matte effects. It enhances the printed surface and adds an extra layer of visual appeal and light protection.
A blank small parcel box for when what actually varies is the label, not the box. Orders start from 100 units.
Every other small parcel box on this range can be printed. Choosing blank on purpose, inside a catalogue built around printing, is worth a real reason rather than a default.
A printed run makes sense when the same design goes on every box. It stops making sense the moment what actually needs to appear is different parcel to parcel, an order number, a returns reference, a customer’s name, since no single printed design can carry that. A sticker or a label applied at the point of dispatch handles it instead, and the box underneath stays blank because it has to. That’s a genuinely different reason from simply not having artwork ready yet, which free design support already solves without needing to drop print altogether.
The board, the construction and the size are specified exactly the same way as any printed small parcel box, matched to the weight and fragility of what’s going inside. Going blank changes the surface, not the build.
Offset, digital and screen printing remain available if a fixed design is wanted after all, since blank is a choice rather than a limitation of the range. Orders start from 100 units. Design support is free. A digital 3D mock-up is free. There are no setup fees. Standard production takes 6 to 8 business days after approval. UK delivery is free.
A confirmed, genuine ready-to-go stock option, unprinted or carrying a pre-made design already applied, rather than a standard custom order simply left unprinted, is Empty Small Parcel Boxes, and it carries the same commercial terms as any custom order. Posting food specifically, where the real question is transit suitability rather than print, is Small Food Parcel Boxes. Anything else in the postal range starts at Small Parcel Boxes.

★★★★★ SANDRA SMITH
This is the first time I have used this company, Thomas assisted me with answering queries and the design of the personalised boxes I was after. Thomas was helpful and knowledgeable and very accommodating in changing design details, always responding quickly with a new version to review. Thomas is very eager to help make sure your packaging is right for you. Sometimes a little too eager chasing for decisions but at least you know someone is handling your enquiry and its not sitting on the bottom of a pile being ignored as I've had experience of elsewhere.
Product takes about 3 weeks to be delivered so can't comment on actual product as yet.

Best customer service! Daniel was great to help me keep the process moving in order for me to meet my business deadlines. He made sure I knew exactly what the boxes would look like and samples were received promptly. I liked the quality of the boxes for the price so much that I added a bunch of labels to the order as well. It has definitely improved the look of packaging in my store.
★★★★★ Natural Zen LLC
This was my first, and won’t be my last, time ordering with ACP UK for my custom packaging. I worked with Frank who walked me through every step. He ensured I understood every aspect of the process and ordering, sent multiple images for me to approve, and checked back in with me when I got them too! Not to mention, my company is all about zero waste and being green so, I had a million questions to ask about the product itself before I even attempted to design anything and he was absolutely amazing and so patient! To date, the best customer service I’ve experienced. I will definitely be ordering again!

ACP UK went above and beyond. Frank took such a personal and hands on approach to making sure this project came out succesfully. We had a tight turn around and with the holidays breathing down our back it was coming down to the wire.

★★★★★ M & L Nugent
I have been working with several companies - trying to nail down a box size and type for my organic tea business. Frank was the ONLY rep in all of the companies I reached out to who was responsive, helpful, and walked me through the entire process. It was an absolute pleasure to give my small business pounds to ACP UK! I will provide another review after I receive my custom product!
JL Aronson
I loved the options and thought the solution we came up with was brilliant. A slide box for a gift thumb drive of irregular shape. Daniel was my rep. Very helpful!

★★★★★ Cory Sweitzer
wonderful service from a company that went beyond expectation to help my project get up and running smoothly. My sales rep, Daniel, and the design team at ACP UK made sure to have every detail in place and gave me a quote other companies could not touch! Lead times were accurate and updates for shipping were by far the most stellar i have yet to see. Thanks a million!
★★★★★ Kaity Burns
Our experience with ACP UK was overall good. They were able to work with our extremely tight timeline and were very responsive and communicative. I will say that there were some things about our final product that we were not happy with, such as creasing of the graphics and images were not full bleed on the cover of our boxes like they were supposed to be. ACP UK was not able to fix the problems on the boxes due to our tight timeline, so we ended up with a product that were were a little less than satisfied with. They offered us a discount on our next order. I think their pricing overall was fair and competitive. We may use them on project in the future again if we are able to see an image of the boxes before they go into full production like we were told that they would do last time.
★★★★★ Shanik Murthy
From the very beginning the team has been nothing but helpful and responsive when it came to my inquiries. Cant thank them enough for all the time and effort they put in to help make the process easier for me! Thank you to Thomas and Daniel specifically!
Michale Anderson
The food boxes are sturdy, neatly printed and easy to assemble. They have made our takeaway presentation look much more professional.

We will definitely use them again!

★★★★★ Nadège Richards
I finally received my order about a month and a half later. Poor communication from the company and I never received shipping confirmation or tracking info until I asked for it. This was from my first experience, however I have now ordered from them 3-4 times and it's been great since then.
★★★★★ Kim Houston-Harris
i have been in business for 5 years and always thought it would be to expensive to have small batch boxes made. Surprise Surprise, a member from my soap facebook group recommended All Custom Packaging UK with a positive review so I gave them a try and a star was born. I felt heard and taken care of along the whole process. I needed my boxes for Mothers Day orders and they made it happen. I'm happy and impressed by the quality.
★★★★★ Caren Henderson Freeman
Fast response to my emails/orders, production time is quick and I love that the shipping is included already in the cost. Not a 4 star only because of some minor production issues with dust, glue, and hanging chads. Customer service is on top of it with fast response and satisfied outcome.
★★★★★ Ashley Andrews
Our skincare company and a sister supplement company have used ACP UK for all of our product boxes for a year now. We are thrilled with the quality of the boxes as well as the responsiveness of the sales and customer service teams. I can't recommend them enough!
Your review will be checked before it appears on the website.
Clear answers about ordering, artwork, production, materials and delivery.
Orders start from 100 units. Standard production takes 6 to 8 business days after approval.
Generally, yes, on a standard uncoated or lightly finished board. A heavier lamination or coating can make an adhesive label less reliable, so if applying your own sticker at dispatch is the plan, it's worth keeping the finish simple and saying so upfront.
No. The board, size and construction are specified the same way as a printed box, and the same commercial terms apply either way.
Not necessarily. Design support is free. That alone makes an unfinished design a poor reason to drop print altogether, since help getting the artwork ready is already available. Blank suits a genuinely different need, content that varies parcel to parcel rather than one design that just hasn't been finished.
An unlaminated paperboard construction may be easier to process through suitable paper-recycling streams than a heavily laminated alternative. Final recyclability depends on the full material and finishing specification and the facilities available locally.
