A flat-packed cardboard box is a packaging option that businesses ship in a collapsed or flat condition. You can send a far greater volume without taking up as much space as it needs to ship ready made boxes. When the product is sold, the user simply pops the plain boxes for gift into shape to create an assembled box. Our experts design each box with pre-scored fold lines for quick and easy assembly.
There are many advantages associated with using these versatile flat packed gift boxes from a retailer end-user's point of view. The custom box supplier in the UK identifies a number of key advantages to using the boxes from the UK supplier, as follows:
To change a basic container into a fantastic gift, add a lid. Supplied by flat pack gift boxes with lids gives a higher level of protection for your items than using an open-top tray or wrapping them in tissue paper.
The lid acts as a barrier from all of the elements that can potentially damage or ruin the item and creates an element of "surprise" when someone opens it.
Choosing the appropriate type of material will influence the strength of the packaging and how it will look. Custom Boxes UK offers many different grades to fit all types of applications.

The best option for developing brands to manage their supply chain is by wholesale purchasing flat pack gift boxes. Buying in bulk provides much lower per-unit pricing and therefore improves profit margins.
Custom Boxes UK helps keep wholesale orders manageable to warehouse teams. Flat packing allows for storing thousands of boxes on a pallet, simplifying the inventory process for an e-commerce reseller.
Not every project will require thousands of products. We make a pack of 5 flatpack gift boxes perfect for start-ups, home-based crafters or individuals. That would like to purchase for their own personal gifting needs. Users may try the pieces with fewer than are normally available for purchase from a wholesale perspective. Thereby having sufficient inventory to test out the quality and size prior to making larger quantities of purchases. They will also provide the same type of commercial grade quality found in wholesale shipments but in a much easier to purchase size.
To assemble Flat-Pack Gift Boxes is a simple process that does not require tools. Once you are comfortable with the process you will be able to assemble the boxes in seconds. By following the easy steps below you will be able to assemble the Flat-Pack Gift Boxes;
1: Open the Box: Start by laying your flat sheet of flat-pack material on a clean surface and open it up to form a box.
2: Secure Bottom Flaps Together: Fold the bottom flaps into the interior of the box — many of the styles will automatically "click" or lock into position as you fold them in.
3: Create Your Box Frame: Push or pull the side panels up to form the box configuration.
4: Attach the Lid: If your lid comes as a separately folded lid then simply fold the corners of the lid and place it over the base of the box; if your lid is already attached to your flaps, then tuck the flap into the front slot or opening in the body of the
