Detailed info on Large Parcel Boxes
As the name would suggest, large parcel boxes are a good solution to consider if you send high volumes of larger parcels via the Royal Mail or other courier / postal networks.
With the guidelines indicating that the length of the boxes must not exceed 1.5 metres to gain the preferential shipping price (or length / depth combined not being more than 3 metres), what it also allows for is a wide range of bespoke sizes within this range.
In fact, it makes sense to source large parcel boxes that are tailored to your specific requirements for a number of reasons. Firstly, a custom size will minimise material usage, and will also eliminate the need or excessive amounts of void fill (both of which increase your business’ costs).
Custom sized postal boxes also tend to provide greater levels of transit protection (as they minimise the contents movement during handling / transportation), whilst selecting a suitable material grade (either single or double wall cardboard) also means a box that is as cost effective as possible, whilst providing a suitable level of performance too.
Besides selecting a material for performance purposes (GWP will be happy to advise the best option for your specific application / product), it also allows you to influence the appearance too.
You can select an organic appearing kraft / brown finish, or a premium white material. Both of these can be further enhanced with a range of printing options, plus specialist coatings that can add pantone colours, resistance to water and even anti static properties.
The size of the large parcel boxes also means they can be easily modified with the inclusion of special fittings and dividers (either fixed or adjustable), which further improve protection, whilst adding flexibility and aiding packing too.
This makes these PIP compatible boxes perfect for a wide range of business types, including those selling or shipping clothing, small appliances, food / drink, consumer electronics and much else besides.
