The letter reads as follows:

SIR,

Globally personal care companies produce some 122 billion plastic sachets each year. If you placed a year’s worth end to end, they would stretch more than 10 million kilometres – equivalent to 27 trips from earth to the moon.
The personal care industry is expected to be the most lucrative end-use market for sachet packaging. Shampoo, moisturiser, perfume, shower gel and face wipes, as well as home care products including detergent and cleaning supplies – are all offered in single-use, valueless and unrecyclable sachets.
Sample sachets are the ultimate symbol of our grab-and-go lifestyle – used to drive instant sales but destined to pollute our planet for centuries. We cannot go on like this.

A raft of solutions already exist. Solutions which use systems and materials that work with nature, not against it. There are no more excuses. Campaign group A Plastic Planet believes it’s time to stamp out non-food plastic sample sachets once and for all. We agree. That’s why today we’re calling on the UK Government and European Union to include plastic single-serve sample sachets in the single-use plastics ban.
