Hinged Lid Cardboard Boxes

Our Hinged Lid Cardboard Boxes provide a compact packaging option for presenting, storing and posting suitable small products. The low-profile shape works particularly well for shallow items that do not require the height of a standard shipping carton.

The attached lid stays connected to the main body of the box. As a result, users do not need to manage separate bases and lids during assembly or packing.

Furthermore, the hinged construction creates a convenient opening for placing, presenting and removing products. Therefore, the box can support online orders, retail goods, samples and small gifts.

The white finish offers a clean appearance for commercial and presentation applications. However, the box may still require an external address label, suitable sealing method and protective outer packaging depending on the intended journey.

Because Hinged Lid Cardboard Boxes use single-wall cardboard, they provide lightweight everyday protection without the bulk of a double-wall carton. Nevertheless, customers should assess the contents and handling risks before dispatch.

Hinged Lid Cardboard Boxes Size and Specifications

The nominal box size is:

• Metric: approximately 139.7mm x 127mm x 50.8mm
• Imperial: approximately 5.5 x 5 x 2 inches

The main product specifications are:

• Measurement order: length x width x height
• Product type: white hinged-lid cardboard box
• Construction: single-wall cardboard
• Colour: white
• Shape: compact and low-profile
• Lid style: attached hinged lid

The measurements for Hinged Lid Cardboard Boxes are nominal. Therefore, small manufacturing tolerances may apply to the folded dimensions.

Additionally, customers should confirm whether the listed size represents internal or external measurements when an exact fit is essential. The usable internal space will generally be slightly smaller because the cardboard has its own thickness.

Understanding Hinged Lid Cardboard Boxes Dimensions

The box measurements follow the order length x width x height. Therefore, the box is approximately 139.7mm long x 127mm wide x 50.8mm high, which is equivalent to approximately 5.5 inches x 5 inches x 2 inches.

Before ordering, measure every part of the intended product. For example, include projecting handles, closures, cables and protective wrapping when checking the required space.

The shallow 50.8mm, or 2-inch, height suits low-profile goods. However, products close to this height may not fit after allowing for cardboard thickness and internal cushioning.

Furthermore, Hinged Lid Cardboard Boxes require enough clearance for the lid to close naturally. Do not force the lid over an oversized or overfilled product.

The completed parcel may qualify for small-parcel services depending on its final dimensions, weight and the carrier’s current rules. Nevertheless, customers should measure the sealed package rather than relying only on the nominal empty-box size.

Choosing Hinged Lid Cardboard Boxes

Choose Hinged Lid Cardboard Boxes when you need a compact white box for suitable shallow items. In particular, consider the product’s dimensions, weight, fragility and presentation requirements.

The hinged design works well for products that customers or staff may need to access easily. Additionally, it reduces the risk of a separate lid becoming misplaced before packing.

The white surface creates a smart appearance for gifts, promotional items and retail products. However, markings, labels and handling can affect the finish, so protect the box where appearance remains critical.

Single-wall cardboard suits many lightweight everyday applications. Conversely, heavy, highly fragile or valuable contents may require a stronger outer carton or additional internal protection.

Choose a box that leaves enough space for suitable cushioning without creating excessive empty space. Consequently, the product can remain controlled while the finished package stays compact.

How to Assemble Hinged Lid Cardboard Boxes

Before assembly, inspect the cardboard for tears, moisture, crushed edges or damaged fold lines. Next, place the box on a clean, dry and stable packing surface.

To assemble Hinged Lid Cardboard Boxes:

1. Open the box carefully without tearing the hinged section.
2. Follow the existing crease lines to form the base and side walls.
3. Fold any internal tabs into their intended positions.
4. Make sure the corners sit square and level.
5. Add a suitable base layer of protective packaging where required.
6. Place the product centrally inside the box.
7. Add protection around the sides and above the item.
8. Bring the hinged lid forward without forcing the fold.
9. Close the box using its intended closure arrangement.
10. Add suitable tape or another closure if the journey requires extra security.
11. Apply any required address, barcode or handling labels.
12. Inspect the finished box before dispatch.

However, do not use staples unless they suit the product, handling environment and delivery method. Sharp fasteners may damage the contents or create a handling risk.

Finally, ensure the lid lies flat and the side walls remain straight. A bulging lid usually indicates excessive filling or an unsuitable product size.

Packing with Hinged Lid Cardboard Boxes

The compact size helps control appropriately sized products. Therefore, Hinged Lid Cardboard Boxes can reduce the need to place a small item inside an unnecessarily large carton.

First, protect delicate surfaces and projecting parts. Then, place a suitable layer of cushioning beneath the item where necessary.

Position the product centrally and avoid direct contact with the side walls when shock protection is important. Afterwards, fill any remaining gaps so the product cannot move excessively.

Suitable internal packaging may include:

• Tissue paper
• Kraft paper
• Corrugated paper
• Bubble cushioning
• White foam
• Cardboard pads
• Small protective sleeves
• Suitable loose-fill material
• Dividers or inserts

However, choose the cushioning according to the product. Polished, painted or delicate surfaces may require a soft, non-abrasive layer, while electronic components may require specialist anti-static packaging.

Do not overfill the box or force the lid closed. Otherwise, internal pressure may damage the product, distort the cardboard or place strain on the hinge.

After closing the box, gently check it for movement. If the item shifts, adjust the internal protection before completing the dispatch.

Hinged Lid Cardboard Boxes for Business, Gifting and Storage

Hinged Lid Cardboard Boxes support businesses that pack compact retail goods and online orders. For example, jewellery sellers, craft businesses, cosmetics suppliers and promotional-product companies can use them for appropriately sized items.

The white finish creates a cleaner presentation than a standard brown transit box. As a result, the packaging can complement gifts, samples and customer-facing products.

Retailers can also use the boxes for click-and-collect orders or protected stock transfers. Meanwhile, offices and workshops can use them to organise small fittings, accessories and components.

Because the lid remains attached, staff can open and close the box without keeping track of a separate component. Nevertheless, repeated opening may eventually weaken the cardboard hinge, depending on the frequency and handling method.

For postal dispatch, secure the box according to the value and nature of the contents. Additionally, apply a clear address label and protect the white surface if the finished presentation matters.

Express Packaging can deliver these boxes to UK mainland addresses. Therefore, businesses can include the product in purchasing plans for different shops, offices and packing stations.

Storing Hinged Lid Cardboard Boxes

Store unused Hinged Lid Cardboard Boxes indoors in a clean, dry and well-ventilated location. Additionally, protect the white surface from dust, dirt and marks.

Keep the boxes away from:

• Rain and condensation
• Damp walls and floors
• Excessive humidity
• Direct sunlight
• Naked flames and ignition sources
• Hot surfaces
• Oils and solvents
• Aggressive chemicals
• Dust and workshop debris
• Crushing pressure
• Rodents and other pests

Moisture can soften cardboard and reduce its structural performance. Therefore, never use a damp box for an application that relies on dependable storage or transit protection.

Store unassembled boxes flat and support them evenly. Otherwise, leaning or uneven stacks may bend the panels and distort the lid.

The white surface can show marks more readily than natural kraft cardboard. Consequently, staff should handle the boxes with clean, dry hands where presentation remains important.

Finally, rotate stock so older undamaged boxes enter use first. Inspect each box before assembly and set aside any damaged packaging.

Alternative Names for Hinged Lid Cardboard Boxes

Customers may also refer to these boxes as:

• White hinged-lid boxes
• White cardboard gift boxes
• Size A cardboard boxes
• Small white postal boxes
• White presentation boxes
• Hinged cardboard cartons
• Single-wall hinged boxes
• Small white packaging boxes
• White product boxes
• Compact gift boxes
• Small e-commerce boxes
• 5.5 x 5 x 2-inch boxes
• 139.7mm x 127mm x 50.8mm boxes
• Shallow white cardboard boxes

Although these terms can describe similar products, dimensions, board grades, closure styles and colours may differ. Therefore, confirm the nominal size, white finish, hinged lid and single-wall construction when comparing products.

In particular, Hinged Lid Cardboard Boxes should not be confused with two-piece boxes that have completely separate lids. The attached lid forms part of this product’s practical design.

Food Safety Information

Direct food-contact suitability has not been confirmed for this box. Therefore, do not place unpackaged food directly against the cardboard.

When packing food or confectionery, keep it completely enclosed within suitable food-contact packaging. Additionally, make sure the cardboard cannot puncture, contaminate or compromise the primary pack.

The box may suit secondary packaging for appropriately sealed food products. However, businesses should complete their own hygiene assessment and request current compliance documents where required.

Furthermore, cardboard can absorb liquids, oils and odours. Replace the box if contamination, dampness or staining occurs.

PPWR Compliance Information

The EU Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40, introduces requirements affecting packaging placed on the EU market.

However, compliance depends on the complete packaging system, supply chain, intended market and applicable implementation dates. Therefore, this description should not be treated as a declaration of PPWR compliance.

Businesses should assess the finished packaging configuration, including the box, tape, labels, inserts and protective materials. Additionally, they should request current technical evidence before making formal regulatory or environmental claims.

Where recycling facilities accept cardboard, remove incompatible components and keep the material clean and dry. Nevertheless, collection and recycling requirements can vary between local authorities and commercial waste providers.

Illustration Only

Product images are for general illustration only. Consequently, the precise white shade, board texture, fold style and finishing details may vary slightly between manufacturing batches.

The stated 139.7mm x 127mm x 50.8mm and 5.5 x 5 x 2-inch measurements are nominal. Therefore, small manufacturing tolerances may apply.

Any products, labels, tape or internal packaging shown in an image are for presentation purposes unless the product listing specifically states otherwise.

Request a sample before committing to an application where the internal fit, white finish or box performance is critical. Additionally, test the complete package under realistic handling, stacking, storage and transport conditions.
