These heavy duty single wall boxes from Kite Packaging are also known as our 'Enviro-box'.
They offer the protection of traditional double wall boxes but use less material.
Our Enviro-box combines superior strength and durability with an efficient material
design. In similar fashion to our single wall cardboard boxes, the heavy duty Enviro-box
features a single-wall structure that offers advanced support over our standard
single wall and double wall boxes.
The Enviro-box is one of the UK’s most environmentally friendly boxes, helping to
reduce material waste in the shipping and moving industry.
Our double wall cardboard boxes also offer heavy duty strength and durability, providing
two layers of corrugated cardboard that increase resistance to crushing during transport
Most of our heavy duty Enviro-boxes are also multi-scored, meaning that the height
of the carton can be adjusted to suit different contents. They have pre-scored fold
lines at heights stated in the table above, simply cut down the corners using a
box cutter and fold along the new
Manufactured from a reinforced single wall, it is robust enough to be reliable yet
cheap enough to be affordable.
The Enviro-box is a versatile and durable choice for individuals and companies requiring
a cardboard product with enhanced strength and portability. Thanks to a reduced-weight
design, the Enviro-box is an efficient and user-friendly alternative to standard
heavy duty boxes. The larger sized heavy duty boxes feature hand holes for ease
Whether for commercial or personal uses, the Enviro-box is well suited to both large-scale
transportation operations and more conventional storage and shipping projects. If
customers are shipping extremely heavy objects, however, we recommend our double-walled
export and pallet boxes. The Enviro-box is also ideal for companies looking to maintain
firm policies on eco-friendly practices.
Available in a range of sizes, customers purchasing the Enviro-box can benefit from
the product’s multiscored construction, allowing for adjustable depth and height
levels. For individuals or organisations purchasing larger orders, bulk pricing
options are available. Wholesale pricing options are also open to our high-volume

boxes. If you are still unsure of anything to do with the boxes then please call
In this video, find out the correct way to measure a box, and learn the difference between internal and external dimensions.
The second dimension is the shortest opening dimension, and the third dimension is always the depth.
Remember that the dimensions are always INTERNAL, the usable space, not the external.
On boxes the difference between internal and external can be very considerable, depending upon the board grade and the style of the box.
Many of our cardboard boxes have multi-score lines that allow the height to be adjusted.
We sell a box cutter that enables this to be done quickly and safely, due to its retractable blade.
Multi-score lines are clearly visible, see the table on the box page for their height.
Using the knife, cut down each corner to the height you require.
Insert your items, then fold down the flaps to the new height.
We sell various types of boxes, from standard duty single wall to extra heavy duty.
Single wall boxes are identified by the prefix ‘CSW’.
Heavy duty Enviro-boxes have a clear ‘Enviro’ print on one of the flaps.
Double wall boxes have a code starting ‘CDW’.
Our single wall boxes have a single layer of corrugated board. They are our best value option for packing lightweight goods. Enviro-boxes are made from a thicker and more rigid single wall board. These are suitable for slightly heavier goods. Double wall boxes have 2 layers of corrugated board, making them our strongest general-use boxes.

Box dimensions refer to the internal (usable) dimensions and are always measured in the same order.
1. Longest opening dimension (length)
2. Shortest opening dimension (width)
3. Depth (height)
Depending on the board grade and flute, the internal and external dimensions of a box can differ significantly. Watch our ‘how to measure a box’ video to find out more.
Corrugated cartons differ in strength depending on the combination of fluting, and weight of paper used, to create a solid board. A single wall box has one layer of fluting, and a double wall box has two (giving extra strength, better suited to heavier items).
Many of our boxes have a ‘multi-score’ feature, giving you the option to vary the depth of the box to a pre-scored dimension. Simply cut the existing slots (between the flaps), fold along the pre-scored crease, and you create a shallower depth carton.

Step 1: How big is your product?
Standard box dimensions are given in the order Length x Width x Height.
Measure the length with a tape measure. Next, measure the width. Measure the height / depth.
Step 2: Select a box that is slightly larger in all 3 dimensions. This will allow for extra padding to protect your product.
You will need the INTERNAL dimensions of the box.
Depending on the board grade, this could be up to 10mm less than the external dimensions.
To check that your box is the correct size, measure the length, width and height on the INSIDE of the box.
All dimensions provided for our boxes are internal.
Step 3: Wrap your product in a suitable padding material and place inside the box.
It should be a snug fit to prevent movement.
Step 4: Close the box and seal with tape or strapping as required.
Consider our custom logo printed tape for a cheap branded sealing option.
Strong cardboard boxes made from double wall cardboard.
General purpose boxes made from single wall cardboard, for packing, shipping & storage.
General purpose packaging tape for various applications. Choose from 66m or cost-effective 150m rolls, and acrylic, hotmelt and solvent adhesives.
