Description

Detailed info on Large Letter Boxes

In 2013, the Royal Mail changed the way in which priced specific sizes of parcels and letters. Known as pricing in proportion, this meant to benefit from specific price bands, your business’ packaging had to fall within pre-defined dimensions / weights.

The large letter boxes as they have become known, must not exceed 353 x 250 x 25 mm (length x width x depth), and have a maximum weight (including packaging and contents) of 0.75 Kg.

As such, your business can source a range of corrugated packaging from GWP which satisfies these requirements.

However, you do not simply need to specify this maximum size. You can choose any size within this range to create a better, tailored fit for your specific products, enhancing the level of protection in transit. It can also help reduce costs by eliminating or minimising any void fill required too.

They can also be created in a range of styles, from pizza style boxes (also referred to as 0427) to 5 panel wraps which fold around your products. If you are unsure of the best design for your application, a member of the GWP team will be happy to advise.

Whatever style you select will be easy, quick and efficient to assemble, and supplied flat packed to minimise storage requirements.

Finally, besides choosing a bespoke size and / or style, you can also choose a natural, eco-friendly kraft brown finish, or a more premium white cardboard appearance. When coupled with a range of one, two or full colour print – that can be applied to the exterior or interior of your large letter boxes – it means you can perfectly match your brand identity.

Whatever options you decide are best for your business, any large letter boxes supplied will use a thin, lightweight yet durable single flute corrugated material. This allows the packaging to maximise the available space of the PIP box guidelines, but also keep the contents safe, secure and free from damage.

All of this makes the large letter cardboard boxes ideal for a range of applications. Any business or ecommerce site selling books, DVDs, computer software or similar sized items could potentially see lower shipping costs as a result of switching to this packaging.

Cost effective packaging for your business

Unlike other suppliers of PIP boxes, GWP Packaging does not hold standard sized boxes. Everything we supply is manufactured bespoke to your business’ requirements.

Whilst this may sound strange for what are essentially boxes defined by a set size, by manufacturing bespoke it allows for packaging that not only provide optimum protection for your items, but is genuinely cost effective in mid to high volumes.

As a trade supplier, GWP is happy to provide you with no obligation quotes on a large letter boxes, guidance on the best packaging for your specific application, and to even advise if you would be better off purchasing stock boxes from a merchant or online seller (i.e. if you only require low volumes, or would not truly benefit from bespoke options).
