Poly Mailers for United Kingdom Businesses
Shipping custom mailer orders to the United Kingdom means producing to your specification and delivering to your address. There is no UK warehouse, no trade counter and no local stock, and this page says so plainly.
UK buyers often use different vocabulary — polythene mailing bags, mailing pouches, plastic postal envelopes — for the same product. They all describe what is on this site, and the specification conversation is the same whichever term you started from.

Terminology, resolved
UK buyers arrive using several different terms. These all describe the same range.
Polythene mailing bags
The most common UK term for what this site calls poly mailers.
Mailing pouches
Usually the same product, occasionally used for smaller formats specifically.
Plastic postal envelopes
Generally the same thing again, sometimes implying a lighter format.
Poly mailers
The term used across this site, adopted from the US market where it is standard.

How supply works for a UK order

Shipped to your address
Tell us about access constraints — no loading bay, upper floors, restricted streets — at quotation stage.

Quotations for UK customers are issued in pounds sterling.
Schedule confirmed in writing
For your specific order rather than as a published figure.
No UK premises
No warehouse, no trade counter and no collection point.
The measurement that matters most here
UK small-parcel pricing is unusually sensitive to parcel thickness, because format thresholds are built around it. For businesses shipping small items in volume, sizing to stay inside a letterbox band is frequently a larger cost lever than anything else in the packaging specification. How to work that out from a real packed parcel is covered on the London page, which deals with format thresholds specifically.

Questions about supplying United Kingdom
Do you supply polythene mailing bags in the UK?
Yes. Polythene mailing bags, mailing pouches and plastic postal envelopes all describe the range on this site. Orders are made to your specification and shipped to your UK address; we hold no UK stock.
What currency are UK quotations issued in?
Pounds sterling. Currency, shipping arrangements and any applicable charges are stated on the quotation rather than assumed.
Can you deliver where there is no loading bay?
Yes, but tell us at quotation stage. No bay, no lift, restricted street access or stairs all change how an order should be structured, and it is far easier to plan around than to run into on the day.
Do you make bags that fit through a letterbox?
We make formats that can, depending on what you put in them — thickness rather than the bag decides it. Check the current format thresholds with your carrier, then measure a real packed parcel against them.
