How it works
See how the carbon footprint of our mailer boxes compare to a benchmark product.
FEFCO 0427Quick to assemble, FEFCO 0427 has a wide, flat interior surface which is ideal for branding or creating a memorable unboxing experience. FEFCO 0427 is durable in transit with each sidewall constructed from two layers of cardboard, providing excellent crush resistance.
Brown kraftFSC-certified, unbleached and uncoated paper made from virgin pulp. Brown kraft is the most sustainable material for these mailer boxes.
White kraftFSC-certified, bleached paper made from recycled and virgin pulp. White kraft liner has a fibrous texture and a matte finish.
White coatedFSC certified, bleached paper made from recycled and virgin pulp. Coated with kaolin clay to create a smooth surface for printing with a shine..
Brown testlinerFSC certified and made from 100% recycled fibres, brown testliner is a cost-effective paper used on any non-printed, brown side of a mailer box. This reduces its carbon footprint and cost. Testliner isn’t printed on as colours can appear muted and finer details can occasionally blur because of its high absorption rate.
White testlinerFSC certified and made from 100% recycled fibres, white testliner is a cost-effective paper used on any non-printed, white side of a mailer box. This reduces its carbon footprint and cost. Testliner isn’t printed on as colours can appear muted and finer details can occasionally blur because of its high absorption rate.
E-fluteE-Flute (1.5-2.0mm) is used for all Sourceful mailer boxes. It has great crush resistance for its weight, provides a flat surface for printing and is easy to fold.
Vegetable-based inksMade with vegetable oils as their primary base, these inks are designed for high-quality offset printing. More sustainable than solvent-based inks.
Water-based dye inksMade with water as their primary base, these inks are more sustainable than solvent-based inks.
Water-based sealantApplied to every printed side of a mailer box. This is a standard part of the offset printing process to ensure colour consistency and avoid scuffing. Does not impact the recyclability of the box.
UV varnishUsed to highlight printed features or create a high gloss, professional finish over an entire print area. UV varnish also protects colours and reduces the risk of colours running when wet. Mailer boxes with a UV varnish are widely recyclable.
Single peel & sealOne strip of adhesive covered with a fibre-based backing paper. A single peel & seal makes fulfilment fast and helps make your packaging tamper-proof. Adding a peel & seal has minimal impact on your carbon footprint.
Double peel & sealTwo strips of adhesive covered with fibre-based backing paper. A double peel & seal makes fulfilment fast and returns easy for your customers.
