Detailed info on Medium Parcel Boxes

Medium parcel boxes, by their very definition, tend to be 610 x 460 x 460 mm in size (or very close), in order that the boxes can benefit from the lower postage costs associated with this.

However, at this size, this can start to cause issues. Whilst it is wise to maximise the available space in some circumstances, if you are consistently sending out products which are smaller than this, it can lead to you using excess void fill to fill the empty space. It can also mean increased costs through unnecessary material usage.

Another issue with using stock PIP packaging sizes (e.g. such as supplied by online ecommerce sites) means you have no choice with regards to the material. Most will simply use double wall cardboard to ensure it is sufficiently strong to hold the maximum 20 Kg weight. There may however be no need for this additional strength if your business is sending bulky but lightweight items.

By selecting bespoke sizes and materials however, you can significantly reduce your costs. This can be by eliminating the secondary void fill packaging, reducing material usage, improving protection (and minimising returns resulting from transit damage), or indeed all three.

Bespoke Medium Parcel Boxes

But there are other ways bespoke medium parcel boxes (and in fact all PIP packaging) can benefit your business.

For example, you can select cost effective 0201 style boxes, which are easily manufactured and supplied flat to save storage. Or alternatively, you can choose a crash lock base, which allows for quicker assembly and reduces the amount of tape required (another cost saving).

Your business can also match your branding, not only through a wide range of print options (from single colour logos to full colour, interior printing) but by using either premium white or eco-friendly kraft material.

Due to the available space, medium parcel boxes can also include a range of other customisation options, including integrated fittings for specific products, or fixed / adjustable dividers to enable the shipping of multiple items in a single carton.

This makes medium parcel boxes perfect for shipping items such as clothing, gifts, multiple DVDs / CDs, home wares and other smaller products.

Maximise the value of your PIP packaging

GWP Packaging are not a supplier of off the shelf packaging products. This means that if you are not a business, or only require very low volumes, we probably won’t be able to help.

However, by manufacturing packaging to your specific requirements, it allows your company to benefit from medium parcel boxes (and indeed any form of corrugated packaging) that offers the optimum level of protection, at the optimum cost. We’ve been doing this successfully for nearly 30 years.

Not sure whether this is the right approach for your business? Well, GWP will be happy to offer genuinely impartial advice on whether you can benefit from using bespoke packaging, as well as providing no obligation quotes as well.
